Civil Law and Wealth Advisory Contract Disputes in Europe

1. Introduction

Wealth advisory contract disputes arise when a financial adviser, wealth manager, private bank, financial intermediary, insurance adviser, family-office professional, or investment consultant allegedly fails to perform the advisory services promised to a client.

The disputes commonly concern:

unsuitable investment recommendations;

failure to understand the client's financial circumstances;

inadequate risk warnings;

misleading representations about expected returns;

undisclosed commissions;

conflicts of interest;

tax-planning advice;

insurance-linked investments;

structured products;

private equity and alternative investments;

portfolio diversification;

inheritance and succession planning;

investment concentration;

unauthorized transactions;

excessive fees;

failure to monitor investments;

negligent portfolio management;

breach of confidentiality;

fraudulent or dishonest advice.

European wealth-advisory disputes are particularly interesting from a civil-law perspective because the advisory relationship is usually treated as a professional services relationship involving enhanced duties of information, loyalty, diligence and suitability.

The central legal question is often not:

"Did the investment lose money?"

but rather:

"Did the wealth adviser perform the advisory mandate with the degree of professional care required by the contract, applicable civil law, and financial-services regulation?"

2. Nature of a Wealth Advisory Contract

A wealth advisory relationship can take several legal forms.

A. Investment-advisory agreement

The adviser recommends investments, but the client ultimately makes the investment decision.

B. Discretionary portfolio-management agreement

The adviser or portfolio manager has authority to make investment decisions within agreed parameters.

C. Financial-planning agreement

The adviser provides broader advice concerning:

investments;

retirement;

tax;

insurance;

succession;

estate planning.

D. Private-banking relationship

A bank may provide:

investment advice;

custody;

financing;

portfolio management;

securities execution;

tax-related coordination.

E. Family-office agreement

A family office may advise on:

investments;

trusts;

succession;

real estate;

private companies;

alternative assets;

intergenerational wealth planning.

The legal duties depend heavily on what the parties actually contracted for.

3. Advisory Relationship Versus Portfolio Management

This distinction is fundamental.

Advisory relationship

The adviser says:

"I recommend that you invest 20% of your portfolio in this structured product."

The client decides whether to invest.

Discretionary management

The client gives the manager authority to invest:

"Manage my portfolio according to the agreed moderate-risk investment mandate."

The manager then has greater responsibility for execution and ongoing management.

Consequently, a court generally cannot determine liability without first identifying the precise nature of the contractual relationship.

4. The European Regulatory Framework

Wealth advisory disputes operate within several layers of law.

Important European frameworks include:

MiFID and MiFID II;

national financial-services legislation;

consumer-protection legislation;

contract law;

tort/delict law;

professional-negligence principles;

anti-money-laundering legislation;

insurance-distribution rules;

data-protection law;

succession and tax law.

MiFID II is particularly important for investment advice because it regulates matters such as:

suitability;

appropriateness;

client classification;

information;

conflicts of interest;

inducements;

product governance.

But regulatory breach and civil liability are not necessarily identical.

A breach of financial regulation may provide evidence of professional misconduct without automatically determining the civil remedy.

5. The Duty of Care

The core civil-law obligation is generally a duty to act as a reasonably competent professional adviser.

The adviser may therefore be required to:

obtain relevant information from the client;

understand the client's objectives;

assess risk tolerance;

consider financial capacity;

understand investment experience;

explain material risks;

recommend reasonably suitable products;

disclose relevant conflicts;

disclose applicable remuneration;

maintain appropriate records;

follow the agreed investment mandate.

The precise scope varies among European jurisdictions.

6. Know-Your-Client Principle

One of the most important principles is know your client.

An adviser should ordinarily understand matters such as:

age;

financial resources;

investment experience;

income;

liabilities;

liquidity requirements;

investment objectives;

risk tolerance;

investment horizon;

tax circumstances where relevant.

For example, recommending a highly speculative product to a client whose contractual objective is preservation of capital may constitute a serious breach.

7. Suitability

Suitability is different from merely giving accurate information.

An adviser may tell a client:

"This product can lose 70% of its value."

But if the client's mandate is capital preservation, the adviser may still have a duty not to recommend the product as suitable.

Thus:

Disclosure ≠ suitability.

An adviser cannot necessarily avoid liability simply by placing risk disclosures in a document.

8. Risk Disclosure

Wealth advisers may need to explain:

possibility of capital loss;

liquidity risk;

market risk;

credit risk;

counterparty risk;

currency risk;

leverage;

concentration risk;

early redemption restrictions;

tax consequences;

complexity of structured products.

The quality of the warning is important.

A technical document containing hundreds of pages of financial terminology may not adequately discharge an adviser's duty if the adviser knows that the client cannot reasonably understand the practical risk.

9. Conflict of Interest

Conflicts are particularly important in wealth-advisory disputes.

For example, an adviser recommends Fund A because:

Fund A pays the adviser a commission;

the adviser owns part of Fund A;

the bank's investment division benefits from the transaction;

the adviser receives a placement fee.

The client may argue that the recommendation was not genuinely independent.

This creates questions concerning:

disclosure;

loyalty;

inducements;

professional ethics;

suitability;

causation.

10. Case Law 1 — Genil 48 and Comercial Hostelera de Grandes Vinos v Bankinter

CJEU, Case C-604/11, 30 May 2013

This is one of the most important EU cases concerning investment advice.

Facts

The dispute involved financial products, including interest-rate swaps, and the interpretation of the obligations imposed on investment firms under the EU Markets in Financial Instruments framework.

Legal issue

The CJEU considered the requirements concerning:

investment advice;

suitability;

appropriateness;

client information;

financial-services obligations.

Importance

The Court confirmed the importance of assessing whether the financial service or product is appropriate or suitable in light of the relevant client circumstances.

Relevance to wealth advisory disputes

This case is fundamental where a client argues:

"The adviser recommended a financial product without properly assessing whether it was suitable for me."

It demonstrates that investment advice is not simply a sales activity. It involves regulatory obligations concerning the client's circumstances and the recommended service.

11. Case Law 2 — BGH III ZR 170/10

German Federal Court of Justice, 3 March 2011

This is an important German civil-law authority concerning investment advisers.

Facts

The case concerned an independent investment adviser and disclosure concerning commissions received from recommending an investment fund.

Legal issue

The question was whether the adviser had a duty to disclose remuneration or commissions received from the investment.

Principle

The Bundesgerichtshof recognised the significance of transparency concerning commissions received by an independent investment adviser.

Importance

The case illustrates a fundamental principle:

A wealth adviser should not conceal financial incentives that may influence the recommendation.

The client's decision may be affected by knowledge that the adviser receives remuneration from the product provider.

Civil-law significance

Failure to disclose relevant remuneration can potentially support:

breach of advisory duty;

damages;

rescission-related arguments where available;

causation arguments.

12. Case Law 3 — BGH III ZR 196/09

German Federal Court of Justice, 15 April 2010

This decision is closely associated with the German jurisprudence on disclosure of commissions in investment advice.

Importance

The BGH addressed the obligation of an independent investment adviser to explain commissions or other financial benefits associated with recommended investment products.

The underlying principle is that the client should be able to assess whether the adviser has an economic incentive to recommend a particular investment.

Application

Suppose a wealth adviser tells a client:

"This fund is the best option for your portfolio."

If the adviser receives a significant commission from the fund provider but does not disclose it where disclosure is legally required, the client may argue that the advice was affected by a hidden conflict.

13. Case Law 4 — Hoge Raad, 27 January 2017, ECLI:NL:HR:2017:107

Supreme Court of the Netherlands

This case concerned an investment-advisory relationship and the bank's special duty of care.

Principle

The Dutch Supreme Court recognised that a professional financial institution has a special duty of care toward an investor in an investment-advisory relationship.

Importance

The duty may require the institution to consider:

financial capacity;

investment experience;

objectives;

risk profile.

The court also considered the possibility of contributory negligence by the investor.

Significance

A wealthy or sophisticated client is not necessarily deprived of protection.

The court must consider the client's actual expertise and circumstances.

14. Case Law 5 — Hoge Raad, 18 January 2013, ECLI:NL:HR:2013:BY4600

This Dutch Supreme Court jurisprudence is highly significant for investment-advisory relationships.

Principle

The bank's special duty of care may require it to:

investigate the client's financial circumstances;

understand investment experience;

understand investment objectives;

warn about risks;

warn when a proposed strategy is inconsistent with the client's circumstances.

Important distinction

A fall in investment value does not automatically prove negligence.

Investment advice involves legitimate market risks.

The claimant must generally demonstrate something more:

that the adviser breached the professional standard applicable at the relevant time.

This prevents courts from turning ordinary investment losses into automatic professional-liability claims.

15. Case Law 6 — Hoge Raad, 19 July 2013 / Related Dutch Advisory Jurisprudence

Dutch Supreme Court jurisprudence also emphasises that the scope of the special duty of care depends upon the nature of the relationship.

A bank providing:

execution-only services,

investment advice,

discretionary management

does not necessarily owe precisely the same duties.

The more the client relies on the institution's professional expertise, the more important the institution's advisory and warning obligations can become.

Application

If a client merely instructs a bank:

"Buy 100 shares."

the bank's duty is different from a situation in which the bank says:

"We have reviewed your entire wealth and recommend this portfolio as appropriate for your retirement."

16. Case Law 7 — French Cour de cassation, Pourvoi No. 18-19.251

Cour de cassation, France

This case concerned the liability of a conseiller en gestion de patrimoine (wealth-management adviser).

Principle

The adviser was expected to:

obtain information about the client's situation;

explain the characteristics and risks of the recommended investment;

assess the suitability of the transaction;

consider its legal and tax implications;

consider its feasibility and reliability.

Importance

This is particularly valuable because it deals directly with the French concept of conseil en gestion de patrimoine rather than merely ordinary banking.

The decision demonstrates that a French wealth adviser can face liability where professional advisory duties are breached.

17. Case Law 8 — French Cour de cassation, Pourvoi No. 19-10.679

This case concerned investment advice and structured investment products.

Facts

The investor had a relatively limited tolerance for capital loss but was advised to invest substantially in a complex structured product.

Legal issue

The dispute concerned whether the adviser had properly performed its duty to:

inform;

warn;

match the investment to the client's risk profile.

Importance

The case illustrates the principle that an adviser must take the client's declared risk tolerance seriously.

If a client indicates that only a small capital fluctuation is acceptable, recommending a product carrying significant capital-loss risk may expose the adviser to liability.

The case is also important for the concept of loss of chance.

18. Case Law 9 — French Cour de cassation, Pourvoi No. 21-16.716

This case concerned insurance-linked investment products and advice from a wealth-management adviser.

Issue

The clients alleged losses caused by failure to provide appropriate:

investment advice;

warnings;

risk-profile matching.

Important procedural issue

The case also dealt with limitation/prescription.

This is important because a client cannot necessarily wait indefinitely after an allegedly defective recommendation.

The French approach considers when the claimant knew or should have known the facts enabling the claim.

Practical significance

Wealth advisers should maintain records showing:

when advice was provided;

what risk disclosures were made;

what client profile was recorded;

when the client became aware of losses.

19. Case Law 10 — French Cour de cassation, Pourvoi No. 21-19.853

This is another French wealth-management dispute concerning investment advice.

Importance

The case involved an insurance product with investment-linked units and allegations that the adviser failed to properly assess:

risk;

suitability;

capital-loss exposure.

The case demonstrates the interaction between:

advisory duties;

investment risk;

limitation periods;

actual knowledge of loss.

It is particularly useful in disputes involving long-term wealth-management products.

20. Case Law 11 — French Cour de cassation / Axyalis and Similar Wealth-Advisory Jurisprudence

French courts have repeatedly emphasised that a wealth adviser may owe a professional duty to:

identify the client's objectives;

determine risk tolerance;

assess the proposed investment;

explain disadvantages;

identify material risks.

The adviser generally does not guarantee investment performance.

This distinction is fundamental.

21. Wealth Advisory as an Obligation of Means

In many civil-law systems, professional financial advice is generally treated as an obligation of means, not an absolute guarantee of success.

Therefore:

The adviser generally promises:

"I will provide competent professional advice."

not:

"Your investment will definitely make 10%."

Consequently, a market loss by itself does not automatically establish liability.

The claimant must usually establish a professional failure.

22. Example: Legitimate Investment Loss

Assume:

client wants a balanced portfolio;

adviser conducts proper suitability assessment;

adviser explains market risks;

client understands the possibility of loss;

investment complies with the mandate;

market subsequently falls by 25%.

The adviser may not be liable merely because the client lost money.

23. Example: Potentially Negligent Advice

Now change the facts:

client requires capital preservation;

client expressly states that losses above 5% are unacceptable;

adviser recommends a highly leveraged structured product;

adviser receives a substantial undisclosed commission;

adviser does not explain the possibility of a 40% capital loss.

A strong civil claim may arise because several duties may have been breached:

suitability;

risk disclosure;

conflict disclosure;

professional care;

contractual obligations.

24. Duty to Understand the Client

A wealth adviser cannot always rely blindly on a standard questionnaire.

Suppose a client's questionnaire says:

"Risk tolerance: high."

But the adviser knows that:

the client is retired;

the investment represents 90% of the client's assets;

the client needs the money for medical expenses;

the client's stated objective is preservation of capital.

The adviser may have difficulty defending a highly speculative recommendation simply by producing the signed questionnaire.

The substance of the advisory relationship matters.

25. Client Sophistication

The client's expertise is an important factor.

A court may distinguish between:

Retail investor

Little investment experience.

Affluent but inexperienced client

Large wealth but limited financial knowledge.

Professional investor

Significant investment expertise.

Institutional investor

Sophisticated financial organisation.

Greater expertise may affect the scope of the adviser's duties, but wealth alone does not equal sophistication.

A person can have €50 million in assets and still lack expertise in derivatives, structured products or private equity.

26. Hidden Commissions

Commission disputes are among the most important wealth-advisory conflicts.

Consider:

Product provider pays adviser 5% of invested capital.

The adviser recommends the product without adequately disclosing the remuneration.

The client later argues:

"You recommended the product because you were financially rewarded for selling it."

The legal questions include:

Was disclosure mandatory?

Was the adviser independent?

Did the commission create a conflict?

Did the client suffer loss?

Would the client have invested without the undisclosed commission?

27. Tax Advice

Wealth advisers frequently recommend investments partly because of tax advantages.

For example:

pension products;

real-estate structures;

insurance wrappers;

tax-advantaged investments;

succession structures.

If the adviser gives incorrect tax advice, the client may incur:

unexpected tax;

penalties;

interest;

loss of tax benefits.

The adviser may face contractual liability if tax advice formed part of the agreed service.

However, courts must distinguish:

incorrect tax advice

from

a subsequent tax-law change that was reasonably unforeseeable.

28. Estate and Succession Planning

Wealth advisory contracts may extend beyond investment management.

They can include:

inheritance planning;

wills;

trusts;

family-company structures;

gifts;

succession vehicles.

An adviser may face liability if it fails to identify an obvious conflict between the client's stated succession objectives and the recommended structure.

For example:

A client wants equal inheritance among three children, but the adviser structures an investment vehicle that unintentionally produces a substantially unequal distribution.

The legal issue may involve both:

contractual professional negligence;

succession law.

29. Private Equity and Alternative Investments

Wealth advisers increasingly recommend:

private equity;

venture capital;

private debt;

hedge funds;

infrastructure funds;

real-estate funds;

art;

wine;

collectibles;

cryptocurrency.

These investments create additional risks:

illiquidity;

valuation uncertainty;

long lock-up periods;

limited transparency;

complex fee structures;

counterparty risk.

A suitability analysis therefore becomes especially important.

30. Structured Products

Structured products are a frequent source of disputes.

They may contain:

derivatives;

barriers;

autocall mechanisms;

leverage;

credit-linked exposure;

conditional capital protection.

A client may sign a lengthy product document without actually understanding its economic consequences.

Courts may examine whether the adviser:

explained the essential risk;

assessed suitability;

properly identified capital-loss exposure;

understood the client's investment objective.

31. Portfolio Concentration

Suppose a client has:

70% of wealth in one company;

20% in cash;

10% diversified assets.

The adviser recommends another 15% investment in the same company.

Even if the company is fundamentally sound, the recommendation may create excessive concentration.

A wealth adviser may therefore have to consider portfolio-level risk, not merely whether each individual product is suitable in isolation.

32. Failure to Monitor

In discretionary management, duties may continue after the initial recommendation.

For example:

The client's circumstances change substantially, but the adviser never reviews the portfolio.

Potential problems include:

retirement;

loss of income;

increased liquidity needs;

change in family circumstances;

increased debt;

change in risk tolerance.

A continuing advisory relationship may therefore create continuing obligations.

33. Unauthorized Transactions

A different category involves transactions outside the client's authority.

Example:

Client authorises a conservative portfolio, but adviser purchases leveraged derivatives without authority.

Potential claims may involve:

breach of contract;

unauthorized mandate;

negligence;

restitution;

damages.

These cases may be easier to establish than a simple claim based upon poor investment performance because the adviser may have exceeded the agreed mandate.

34. Causation

Even where an adviser breached a duty, the claimant normally needs to establish that the breach caused legally recoverable loss.

The court may ask:

What would the client have done if proper advice had been given?

Possible answers include:

invested in a safer product;

kept money in cash;

diversified;

invested in government bonds;

declined the transaction.

This is why many wealth-advisory disputes involve loss-of-chance analysis.

35. Loss of Chance

Suppose an adviser failed to warn a client about the risk of capital loss.

The client cannot necessarily prove:

"I definitely would have invested elsewhere."

Instead, the client may argue:

"Had I been properly advised, I had a substantial chance of choosing a safer investment."

Some European courts may compensate the lost opportunity according to the applicable national rules.

French jurisprudence has particularly developed the concept of perte de chance in professional-advice disputes.

36. Comparative Treatment of Damages

Possible damages include:

Actual financial loss

The reduction in investment value.

Avoidable loss

Loss that proper advice would probably have prevented.

Lost opportunity

The value of a lost investment opportunity.

Additional costs

For example:

tax;

advisory fees;

transaction costs.

Non-pecuniary loss

Generally more difficult in commercial investment disputes, but potentially relevant depending on national law.

37. Contributory Negligence

An adviser may argue:

"The client ignored our warnings."

or:

"The client knowingly chose the investment."

Civil-law systems may reduce damages where the claimant contributed to the loss.

However, the claimant's sophistication and reliance on professional advice are important.

A signed risk document does not necessarily eliminate liability if the adviser fundamentally failed to perform its advisory duties.

38. Contractual Limitation of Liability

Wealth-management contracts frequently contain clauses such as:

"The adviser shall not be liable for market losses."

Such clauses may be enforceable to some extent.

But they may not protect the adviser against:

fraud;

intentional misconduct;

gross negligence;

mandatory statutory duties;

regulatory obligations;

certain consumer claims.

The validity of limitation clauses depends heavily on national law.

39. Documentation

Documentation is critical.

A wealth adviser should preserve:

client questionnaires;

risk profiles;

suitability assessments;

investment proposals;

emails;

meeting notes;

commission disclosures;

conflict disclosures;

product documents;

investment mandates;

periodic reviews.

In litigation, these records can determine whether the adviser actually performed the required advisory process.

40. Regulatory Breach Versus Civil Liability

An important distinction is:

Regulatory breach does not automatically equal damages liability.

For example, an adviser may breach a regulatory recordkeeping rule without causing any financial loss.

Conversely, a claimant may have a civil claim based on professional negligence even where the regulatory breach is not itself the cause of action.

Courts therefore frequently separate:

existence of duty;

breach;

causation;

damage;

available remedy.

41. Limitation and Prescription

Limitation is especially complicated in long-term wealth-management relationships.

Potential dates include:

date of advice;

date of investment;

date of loss;

date of maturity;

date client discovered the problem.

For structured products, the client may not know the ultimate economic loss until maturity.

French case law involving wealth advisers has specifically addressed the relationship between investment losses and the commencement of limitation periods.

42. Cross-Border Wealth Advisory

Cross-border disputes are increasingly common.

Example:

French resident + Swiss wealth manager + Luxembourg investment fund + German custodian.

The contract may raise questions concerning:

governing law;

jurisdiction;

EU private international law;

consumer protection;

financial-services regulation;

recognition and enforcement.

The claimant may need to distinguish:

where the adviser is located

from

where the client suffered the financial consequences.

43. Arbitration

High-value wealth-management agreements may contain arbitration clauses.

Arbitration can be attractive because:

proceedings may be confidential;

arbitrators may possess financial expertise;

cross-border enforcement may be easier;

complex contractual disputes can be handled privately.

But mandatory consumer protections may limit the effectiveness of arbitration clauses in certain circumstances.

44. Typical Claims Against Wealth Advisers

A claimant may plead:

Contractual breach

Failure to perform the advisory mandate.

Professional negligence

Failure to act as a reasonably competent adviser.

Misrepresentation

False or misleading statements.

Failure to warn

Insufficient explanation of material risks.

Unsuitability

Recommendation inconsistent with client's circumstances.

Conflict of interest

Undisclosed economic incentives.

Unauthorized dealing

Transactions outside the mandate.

Fraud

Intentional deception.

Breach of fiduciary or equivalent loyalty duties

Where recognised under the applicable national legal system.

45. Typical Defences

The adviser may argue:

the client was sophisticated;

all risks were disclosed;

the client independently selected the investment;

the investment complied with the agreed risk profile;

the loss resulted from market movements;

no causation exists;

the client would have made the same investment anyway;

the claim is time-barred;

the contract excluded liability;

the claimant contributed to the loss.

46. Practical Hypothetical

Assume a wealthy client enters a five-year wealth-management agreement with a European private bank.

The contract says:

moderate risk;

capital preservation;

diversified portfolio.

The client has €10 million.

The adviser recommends:

€3 million in a highly concentrated structured product;

€2 million in an illiquid private fund;

€1 million in a leveraged derivative-linked product.

The adviser receives commissions from the product providers.

Two years later, the portfolio loses €3 million.

The client sues.

47. Legal Analysis of the Hypothetical

Issue 1 — What was the mandate?

The court first examines the contract.

If it expressly required moderate risk and capital preservation, that is highly significant.

Issue 2 — Was suitability assessed?

The adviser must show that the recommendations were appropriate for the client's circumstances.

Issue 3 — Were risks disclosed?

The court considers the quality—not merely existence—of risk warnings.

Issue 4 — Were commissions disclosed?

Hidden commissions may create a conflict-of-interest problem.

Issue 5 — Was the portfolio excessively concentrated?

The court may assess portfolio-level risk.

Issue 6 — Was the client sophisticated?

The client's wealth does not automatically prove financial expertise.

Issue 7 — What caused the loss?

The claimant must connect the advisory breach to the financial loss.

Issue 8 — What would proper advice have produced?

The court may need to assess the alternative investment scenario.

48. Case Law Comparison

49. Core Principles Emerging from European Case Law

The cases demonstrate several recurring principles.

Principle 1 — Wealth advisers owe professional duties

A professional adviser cannot simply say:

"The client signed the documents."

The adviser must perform the agreed professional service competently.

Principle 2 — Client circumstances matter

Advice must be assessed against:

objectives;

financial position;

risk tolerance;

experience;

investment horizon.

Principle 3 — Investment losses alone are insufficient

A falling portfolio does not automatically establish negligence.

The claimant normally must prove a breach.

Principle 4 — Commissions can matter

Undisclosed remuneration may create a significant conflict-of-interest issue.

Principle 5 — Risk disclosure must be meaningful

Technical disclosure may not necessarily discharge a professional duty if the recommendation itself was unsuitable.

Principle 6 — Sophistication matters but is not absolute

A wealthy client is not automatically a professional investor.

Principle 7 — Causation remains essential

The claimant must normally demonstrate that proper advice would probably have avoided or reduced the claimed loss.

Principle 8 — Limitation can defeat otherwise arguable claims

Clients must carefully examine when the relevant limitation period began.

50. Distinction Between Wealth Adviser and Investment Manager

This distinction can substantially affect liability.

51. Distinction Between Advice and Sales

Another critical issue is whether the professional actually provided investment advice or merely sold a product.

If the adviser merely executes the client's independent instructions, its duties may differ from those of an adviser who actively recommends the product.

Courts therefore examine:

communications;

marketing materials;

contracts;

meeting records;

product recommendations;

client profiles.

A company cannot necessarily avoid advisory obligations simply by calling itself a "sales intermediary" if, in substance, it provided personalised recommendations.

52. Wealth Advisory and Consumer Protection

Where the client qualifies as a consumer, additional protection may arise.

Potential issues include:

unfair contractual terms;

transparency;

information duties;

jurisdiction clauses;

liability exclusions;

arbitration clauses;

unfair commercial practices.

High net worth does not necessarily remove consumer status.

The legal classification depends upon the client's role and the applicable legislation.

53. Wealth Advisory and Digital Platforms

Modern wealth advisory increasingly uses:

robo-advisers;

algorithmic portfolio management;

AI-generated investment recommendations;

automated suitability assessments.

This creates new civil-law questions:

Who is responsible for an algorithmic recommendation?

Was the client's risk profile correctly classified?

Was the algorithm defective?

Was the human adviser required to review the recommendation?

Who bears responsibility for inaccurate client data?

Traditional professional-liability principles can potentially be applied to these new technologies.

54. Wealth Advisory and Cryptocurrency

Where advisers recommend:

cryptocurrency;

tokenised assets;

digital assets;

decentralised-finance products,

the suitability and risk-disclosure issues become particularly important.

A court may examine:

volatility;

liquidity;

custody risk;

regulatory uncertainty;

counterparty risk;

fraud risk.

An adviser who presents an extremely volatile digital asset as a conservative investment could face substantial professional-liability issues depending upon the applicable law.

55. Drafting a Strong Wealth Advisory Contract

A carefully drafted agreement should specify:

Scope of services

What exactly is the adviser providing?

Investment mandate

What investments are permitted?

Risk profile

What level of risk is acceptable?

Review frequency

How often must the portfolio be reviewed?

Conflicts

How are conflicts disclosed and managed?

Remuneration

Who pays the adviser?

Commissions

Are product-provider commissions permitted?

Liability

What limitations are legally permissible?

Reporting

What information must be supplied to the client?

Termination

How can either party terminate?

Governing law

Which country's law applies?

Dispute resolution

Courts or arbitration?

56. Checklist for Claimants

A claimant considering a wealth-advisory action should collect:

advisory agreement;

investment mandate;

risk questionnaire;

suitability reports;

portfolio statements;

emails;

meeting notes;

product documents;

commission information;

fee statements;

tax advice;

investment-performance records;

evidence of financial objectives;

evidence of losses;

communications concerning warnings.

The chronological record is often critical.

57. Checklist for Wealth Advisers

Advisers should maintain evidence showing:

what the client wanted;

what information the client supplied;

what risk profile was established;

what alternatives were considered;

why the product was suitable;

what risks were explained;

what commissions were disclosed;

what conflicts were identified;

what reviews were conducted;

what instructions the client gave.

Good documentation can be as important as the quality of the advice itself.

58. Overall Conclusion

Wealth advisory contract disputes in Europe sit at the intersection of civil contract law, professional negligence, financial regulation, consumer protection and investment law.

The central civil-law principle is that a wealth adviser is generally not an insurer of investment performance. Market losses alone do not ordinarily establish liability. The crucial question is whether the adviser performed the agreed professional service with the competence, diligence, information, warning, suitability and loyalty required by the applicable law.

The European case law demonstrates several particularly important themes:

Genil 48 (C-604/11) establishes the importance of suitability and investment-service obligations at EU level.

BGH III ZR 170/10 and III ZR 196/09 illustrate the German emphasis on transparency concerning adviser remuneration and conflicts.

Dutch Supreme Court jurisprudence recognises a special duty of care in investment-advisory relationships and requires consideration of the client's circumstances.

French Cour de cassation jurisprudence concerning conseillers en gestion de patrimoine emphasises information, warning, suitability, professional competence and, in appropriate cases, compensation for loss of chance.

Ultimately, a successful wealth-advisory claim normally requires a structured analysis of:

contract → scope of mandate → client profile → advisory duty → suitability → risk disclosure → conflicts/commissions → breach → causation → loss → limitation → remedy.

The most important practical lesson is that wealth-management liability is assessed by reference to the advisory process, not merely the eventual investment result. A properly documented investment that loses money because of ordinary market risk may create no liability, while an investment that performs well can still generate liability if the adviser fundamentally breached mandatory professional duties.
