1. Meaning: Unauthorized Device Monitoring in Marriage

Marriage unauthorized device monitoring disputes arise when one spouse secretly accesses or tracks the other spouse’s:

• Mobile phone (calls, SMS, WhatsApp chats)
• Email or cloud accounts
• Social media accounts (Instagram, Facebook, etc.)
• Location via GPS tracking apps
• Spyware / screen mirroring apps
• Call recording apps installed without consent

These disputes usually surface in:

• Divorce (cruelty/adultery allegations)
• Domestic violence complaints
• Custody battles
• Financial concealment allegations

2. Core Legal Issues

(A) Right to Privacy in Marriage

Indian courts have repeatedly held that marriage does NOT destroy privacy rights.

Even spouses:

• cannot hack devices
• cannot install spyware
• cannot secretly intercept communications

(B) Admissibility of Illegally Obtained Digital Evidence

Courts face a conflict:

• Privacy violation vs truth-finding in trial
• Whether illegally obtained chats/recordings can still be used in court

3. Key Constitutional and Statutory Provisions

• Article 21 – Right to privacy (life and personal liberty)
• Section 72, IT Act 2000 – Breach of confidentiality
• Section 66, IT Act – Computer-related offences (hacking/unauthorized access)
• Section 65B, Evidence Act / Bharatiya Sakshya Adhiniyam, 2023 – electronic evidence certification
• Section 122 Evidence Act – marital communications privilege (limited exceptions)

4. Major Judicial Principles

1. Spousal Privacy is Fundamental

Courts recognize that surveillance destroys marital trust.

2. Unauthorized interception = violation of Article 21

Even a spouse cannot justify hacking on “marriage grounds”.

3. Evidence may still be considered—but scrutinized

Some courts admit illegally obtained evidence, but others reject it.
