Civil Law and UAE — Key Civil Law Principle Digest

1. Introduction

UAE civil law is built around a combination of contractual autonomy, good faith, protection against abuse of rights, compensation for actual loss, causation, fairness, legal certainty, and judicial discretion.

A particularly important development is that the Federal Decree by Law No. 25 of 2025 promulgating the Civil Transactions Law is now the principal federal civil-law framework. The new law came into force on 1 June 2026, so current analysis should distinguish the new provisions from cases decided under the former 1985 Civil Transactions Law.

One important current provision is Article 120, which states that contracts are governed by consent and the obligations undertaken by the parties, while also requiring contractual interpretation to achieve justice and good faith. It further protects the weaker party in cases of ambiguity or inconsistency.

2. Core UAE Civil Law Principles — Digest

3. Principle of Contractual Autonomy

The starting point of UAE civil law is that parties are free to determine their contractual relationship within the limits of mandatory law, public order and applicable legal restrictions.

Current Article 120 expressly begins with the proposition that the governing principle of a contract is the consent of the contracting parties and what they have undertaken in the contract.

Example

If A and B agree:

• price = AED 1 million;
• delivery = 30 June;
• payment = 50% advance and 50% on delivery;

a court does not ordinarily rewrite these commercial terms simply because another arrangement might appear more commercially attractive.

Key idea

Freedom of contract → contractual certainty → judicial respect for the bargain.

4. Pacta Sunt Servanda — Contracts Must Be Performed

A fundamental civil-law principle is that a valid contract creates binding obligations.

This principle protects commercial certainty. Businesses must be able to rely upon contracts without assuming that a court will routinely redesign the bargain.

However, contractual binding force does not mean that every contractual term operates without limitation. Mandatory statutory rules, good faith, abuse-of-rights principles, hardship provisions and other statutory controls can affect the result.

Important distinction

Contractual freedom does not mean unlimited contractual freedom.

5. Good Faith

Good faith is one of the most important principles in UAE private law.

Historically, former Civil Code Article 246 required performance in accordance with the contract and consistently with good faith. Current UAE law continues the importance of good faith through its contractual interpretation framework, including Article 120.

Article 120(11) now expressly provides that a contract should be interpreted in a manner achieving justice and good faith between the parties.

Good faith can involve:

1. honest performance;
2. avoiding deception;
3. respecting legitimate contractual expectations;
4. not deliberately frustrating contractual performance;
5. exercising contractual powers for legitimate purposes;
6. cooperating where cooperation is required by the nature of the transaction.

But good faith does not automatically create a new contract or require a party to surrender legitimate contractual interests.

6. Case Law — Access Group DWC LLC & Proex Partners Ltd v BLS International FZE

Access Group DWC LLC & Proex Partners Ltd v BLS International FZE [2023] DIFC CFI 091

This case is useful because the DIFC Court considered UAE-law contractual principles, including the former Civil Code provisions concerning good faith and abuse of rights.

The judgment discussed former Articles 106 and 246 and described good-faith performance as involving honest performance, avoidance of deception and abusive conduct, and respect for the legitimate interests of the counterparty.

Principle

Good faith is not merely an abstract moral concept. It can influence the manner in which contractual rights are exercised and obligations performed.

Importance

The case demonstrates that contractual rights and good faith operate together rather than as completely separate principles.

Caution: this was decided under the former Civil Code framework and in the DIFC Courts. It should therefore be used as persuasive/illustrative authority when analysing the current 2026 federal Civil Transactions Law.

7. Abuse of Rights

The principle of abuse of rights prevents a person from treating the existence of a legal right as an unlimited licence to harm another person.

Under the former UAE Civil Code Article 106, exercise of a right could be unlawful where, among other circumstances:

• there was intentional infringement;
• the desired interest conflicted with law/public order;
• the benefit sought was disproportionately small compared with harm caused; or
• the exercise exceeded accepted custom and practice.

These concepts remain highly important when understanding UAE private-law methodology, although current cases must be checked against the new 2025 Civil Transactions Law.

Example

A creditor may have a legitimate contractual right, but deliberately exercising that right solely to cause disproportionate harm can raise an abuse-of-right issue.

8. Interpretation — Intention Over Mere Words

Current Article 120 specifically provides several interpretive rules.

Among them:

• intention and meaning are considered rather than words and forms alone;
• literal meaning remains important;
• express terms generally prevail over implications;
• contractual wording should be given effect where possible;
• commercial custom can be relevant;
• surrounding factual circumstances can be considered;
• ambiguity or inconsistency may be construed in favour of the party bearing the obligation or the weaker party. 

Therefore, UAE contractual interpretation is neither purely literal nor completely discretionary.

The court normally moves through a structured process:

Text → intention → contractual context → circumstances → custom → good faith/justice.

9. Case Law — Bank of Singapore Ltd v Marj Holding Ltd

Bank of Singapore Ltd v Marj Holding Ltd & Mohammed Ahmad Ramadhan Juma [2022] DIFC CFI 090

The DIFC Court considered whether contractual discretionary powers should be subject to implied duties of good faith, rationality and proper purpose.

The court emphasised that fairness alone is insufficient to imply a contractual term. The relevant test for implication is necessity rather than simply whether the proposed term appears reasonable.

Principle

Good faith cannot simply be used by a court to insert whatever term appears fair after the dispute has arisen.

Importance

This illustrates an important equilibrium:

Good faith limits abusive conduct, but does not destroy contractual autonomy.

10. Good Faith Does Not Require Renegotiation of Fundamental Terms

Hexagon Holdings (Cayman) Ltd v DIFC Authority & DIFC Investments LLC

[2019] DIFC CFI 013

The case concerned contractual obligations to use “best endeavours in good faith”.

The court held, in substance, that a good-faith/best-endeavours obligation did not require a party to renegotiate the fundamental commercial terms of the existing agreement.

Principle

Good faith facilitates performance of an existing bargain; it does not automatically authorise the court to manufacture a new bargain.

Exam point

Good faith ≠ compulsory renegotiation.

11. Justice and Contractual Interpretation

The current law makes the relationship particularly clear.

Article 120(11) expressly states that a contract should be interpreted in a manner achieving justice and good faith between the parties.

This does not mean that courts can disregard clear contractual terms whenever they consider another outcome fair.

Instead, justice functions within the statutory framework of interpretation.

Practical formula

Clear contract + lawful term → normally enforce

Ambiguous contract → interpret using statutory rules

Abusive exercise → possible legal intervention

Mandatory statutory rule → contractual term cannot override it

12. Principle of Compensation for Damage

Civil liability generally requires consideration of:

1. legally recognised wrongful conduct;
2. damage;
3. causal connection;
4. appropriate legal basis for liability.

The purpose of compensation is ordinarily reparation rather than punishment.

The claimant should generally be placed, so far as legally possible, in the position that would have existed without the wrongful conduct.

13. Principle of Actual Damage

A central civil-law concept is that compensation should correspond to the damage legally attributable to the defendant.

Damage may include:

• actual financial loss;
• lost profits where legally recoverable;
• physical damage;
• certain forms of non-economic harm where recognised by law.

But a claimant cannot simply identify a large contractual or commercial loss and assume that the entire amount is recoverable.

The court considers:

Loss → causation → foreseeability/legal limits → evidence → appropriate compensation.

14. Agreed Compensation / Contractual Penalty

The current Civil Transactions Law contains a particularly important provision in Article 340.

The parties may predetermine compensation in the contract or a subsequent agreement.

However, the court may reduce agreed compensation where the statutory conditions are satisfied, including where:

• the debtor establishes that the agreed amount is excessive;
• the original obligation has been partially performed;
• the creditor contributed by fault to the occurrence or increase of the damage.

Where fraud or gross fault is established, the creditor may in the appropriate circumstances claim compensation exceeding the agreed amount.

Important change

This is now governed by Article 340, rather than former Article 390.

Therefore, older cases referring to Article 390 remain useful for historical interpretation, but current legal analysis should begin with Article 340.

15. Case Law — Dubai Court of Cassation, Appeal No. 222 of 2005

Judgment of 19 June 2006

Under former Article 390, the Dubai Court of Cassation recognised the court's power to adjust agreed compensation so that it corresponded with the actual damage established in the case.

Principle

An agreed damages clause is important evidence of the parties' assessment, but statutory judicial control can prevent an unjustified or excessive result.

Current relevance

The case should now be read alongside current Article 340, rather than treated as a direct statement of the wording of the present law.

16. Proportionality

Proportionality appears throughout UAE civil law.

It can arise in:

• contractual penalties;
• damages;
• abuse of rights;
• hardship;
• injunctive relief;
• enforcement;
• procedural sanctions.

The basic idea is:

The legal consequence should remain appropriately connected to the protected interest and the actual circumstances of the dispute.

Proportionality does not mean that every dispute must produce an equal outcome for both parties.

17. Hardship

UAE civil law distinguishes hardship from force majeure.

Hardship concerns situations where unforeseen exceptional circumstances make contractual performance extraordinarily onerous while performance may still technically be possible.

Under the current framework, statutory hardship provisions can permit judicial adjustment or other intervention when their legal requirements are satisfied.

Example

A long-term commercial contract becomes extraordinarily burdensome because of an unforeseeable exceptional event.

That does not automatically cancel the contract.

The court must consider the statutory conditions and circumstances.

18. Force Majeure

Force majeure is conceptually different.

The basic question is generally whether an external event legally qualifies to prevent or excuse performance.

Difference

Thus:

Expensive ≠ impossible.

19. Procedural Fairness and Justice

Justice is not confined to substantive contractual rights.

It also affects civil procedure.

Oman Insurance Co PSC v Globemed Gulf Healthcare Solutions LLC

[2021] DIFC CA 009

The DIFC Court of Appeal discussed the overriding objective and the need to balance justice, fairness and procedural efficiency.

The judgment recognised that excessive procedural delay can itself cause injustice, particularly in substantial commercial litigation.

Principle

Procedural justice requires both:

• a fair opportunity to present a case; and
• efficient administration of proceedings.

Exam formula

Justice = fairness + procedural efficiency + appropriate judicial discretion.

20. Public Policy

Public policy represents a boundary beyond which private contractual autonomy cannot operate.

Examples can include matters involving:

• fundamental legal principles;
• illegality;
• serious violations of mandatory law;
• fundamental principles of justice.

The concept is normally applied cautiously, particularly in arbitration enforcement.

It should not be confused with the proposition that a judge may simply substitute personal notions of fairness for the parties' contract.

21. Case Law — Nihan v Nicholas & Niaz

Nihan v Nicholas & Niaz [2024] DIFC CA 012

The DIFC Court of Appeal considered the public-policy threshold and emphasised that the exception is concerned with fundamental principles of justice and fairness, rather than every alleged violation of mandatory law.

Principle

Public policy is a narrow protective mechanism, not a general appeal against an unfavourable legal result.

Importance

It demonstrates the boundary between:

ordinary legal error/disagreement

and

fundamental public-policy violation.

22. Burden of Proof

A fundamental evidentiary principle is:

The person asserting a right generally bears the burden of proving the facts necessary to establish it.

This becomes particularly important in civil litigation involving:

• unpaid debts;
• breach of contract;
• negligence;
• damages;
• fraud;
• causation;
• ownership;
• agency;
• contractual performance.

The UAE Evidence Law also recognises legal and judicial presumptions, allowing certain facts to be inferred or presumed under specified circumstances.

23. Judicial Discretion

UAE courts exercise substantial discretion in areas such as:

• evaluation of evidence;
• assessment of damage;
• causal connection;
• contractual compensation;
• expert evidence;
• certain procedural matters;
• statutory hardship;
• proportionality.

But judicial discretion is not unlimited discretion.

A decision should remain connected to:

1. applicable legislation;
2. evidence;
3. reasons;
4. relevant legal principles.

24. Case Law — Access Group and the Limits of Good Faith

The Access Group litigation is particularly useful because it demonstrates both sides of the principle.

The claimants relied upon good faith and abuse-of-right concepts, but the court distinguished between obligations arising during contractual performance and obligations during pre-contractual negotiations. The court held that the good-faith performance obligation could not simply create a duty to renew or renegotiate a contract where no such obligation existed.

Principle

Good faith operates within the legal relationship actually created by the parties.

It does not automatically create a continuing obligation to enter into a new contract.

25. Custom and Commercial Practice

UAE civil law gives considerable importance to:

• established commercial practices;
• trade usage;
• customary terms;
• industry practices.

Current Article 120 specifically provides that what is customary among merchants can be treated as a contractual condition between them.

Example

If a particular industry consistently follows a recognised billing practice, that practice may become relevant when interpreting an otherwise incomplete commercial agreement.

However, custom cannot ordinarily override an express mandatory legal rule.

26. Protection of the Weaker Contracting Party

The modern UAE civil-law framework recognises that contractual equality in theory does not always mean economic or informational equality in practice.

Current Article 120 provides special interpretive protection where ambiguity or inconsistency exists, including protection for the weaker party and the adhering party in relevant adhesion contracts.

This principle is especially important in:

• standard-form contracts;
• consumer contracts;
• financial agreements;
• insurance;
• employment-related agreements;
• digital platform contracts.

27. Equilibrium Between Competing Principles

The UAE civil-law system can be understood as attempting to maintain equilibrium among several competing values:

Contractual autonomy

“Respect what the parties agreed.”

Good faith

“Perform and exercise rights honestly.”

Justice

“Interpret and apply the law fairly.”

Proportionality

“Avoid excessive legal consequences.”

Legal certainty

“Do not rewrite contracts without legal justification.”

Public policy

“Private agreement cannot override fundamental mandatory principles.”

This creates an important overall formula:

Autonomy + good faith + proportionality + legal certainty + mandatory law = UAE civil-law equilibrium.

28. Six Key Case Laws — Quick Revision Table

The first five are DIFC authorities, so they should not be treated as binding authorities on mainland UAE courts merely because they concern UAE-based transactions. The 2005 Dubai Cassation case is a mainland UAE authority under the former Civil Code and is principally useful for understanding the historical development of agreed-compensation doctrine.

29. Key Civil Law Principles — One-Line Digest

For examination or quick revision:

1. Consent — parties are generally bound by their agreement.
2. Pacta sunt servanda — valid contracts must be performed.
3. Good faith — contractual performance must satisfy good-faith requirements.
4. Abuse of rights — legal rights cannot be exercised unlawfully.
5. Intention over form — contractual meaning is important, not merely labels.
6. Literal meaning — clear contractual language normally receives effect.
7. Custom — commercial usage can supplement contractual interpretation.
8. Weaker-party protection — ambiguity may be interpreted protectively.
9. Actual damage — compensation is connected to legally recoverable loss.
10. Causation — damage must be legally connected to the wrongful act.
11. Proportionality — excessive consequences may be controlled where legislation permits.
12. Hardship — exceptional circumstances may justify statutory intervention.
13. Force majeure — legally qualifying external prevention may affect liability.
14. Burden of proof — the asserting party generally bears the evidentiary burden.
15. Public policy — private agreements cannot defeat fundamental mandatory principles.
16. Judicial discretion — discretion must remain grounded in law and evidence.
17. Procedural fairness — parties should receive a fair opportunity to present their cases.
18. Legal certainty — fairness does not ordinarily authorise wholesale rewriting of contracts.

30. Exam-Oriented Conclusion

The key civil-law principle digest of the UAE can be reduced to the following formula:

Contract + Consent + Good Faith + No Abuse + Proportionality + Compensation + Causation + Legal Certainty + Justice + Public Policy.

The most important conceptual point is that UAE civil law does not treat justice as a free-standing power to disregard contractual obligations. Instead, justice operates within a structured legal system that simultaneously protects contractual autonomy, good-faith performance, legitimate expectations, weaker parties, proportionality and fundamental public policy.

The current Article 120 is particularly significant because it expressly connects contractual consent with interpretation based on justice and good faith, while preserving rules concerning literal meaning, express terms, commercial custom and protection of the weaker party.

Short revision formula

“Consent creates the contract; good faith governs its performance; interpretation determines its meaning; causation connects wrong to damage; compensation repairs loss; proportionality controls excess; public policy sets the outer boundary.”
