A client tells their lawyer the whole truth only when they are sure it will stay between them. If the police or the other side could later force the lawyer to repeat what was said, no client would speak freely, and the advice would be worthless. Indian evidence law protects that trust. Section 132 of the Bharatiya Sakshya Adhiniyam, 2023 (BSA) keeps communications between an advocate and a client confidential and out of evidence, with narrow exceptions. This explainer sets out what the section covers, the old provision it replaced, the limits on the protection, and what the Supreme Court held in 2025. Last verified October 2026.

The short answer
  • What it is: advocate-client privilege, the rule that keeps client communications, documents and advice confidential and out of evidence.
  • New-code section: Section 132 of the Bharatiya Sakshya Adhiniyam, 2023.
  • Old section it replaced: Section 126 of the Indian Evidence Act, 1872. This is an evidence rule, so there is no punishment attached.
  • When it does not apply: communications in furtherance of an illegal purpose, and facts showing a crime or fraud committed since the engagement began.
  • Tracking cases: Claw tracks matters under this section across 9,102 forums.

01The problem the rule solves

Legal advice only works if the client is honest. A client who hides facts to protect themselves ends up with weak advice and a weak case. So the law gives the client a promise: what you tell your advocate stays protected, and no one can make the advocate disclose it in court.

This protection is not a favour to lawyers. It belongs to the client. It is what lets a person describe an awkward fact, ask about the worst case, or admit a mistake, knowing the conversation cannot be turned into evidence against them.

Section 132 of the BSA is the section that carries this promise in Indian evidence law. It applies in both civil and criminal matters, across all courts.

02What Section 132 says

Section 132 of the BSA bars an advocate from disclosing, without the client’s express consent, three things: any communication made to the advocate by or for the client in the course of and for the purpose of the engagement; the contents or condition of any document the advocate saw in that course; and any advice the advocate gave the client.

The protection does not end when the matter ends. The Explanation to the section makes clear that the duty continues after the engagement is over. A lawyer cannot reveal an old client’s confidence years later.

The privilege belongs to the client

Only the client can waive it, and the waiver must be express. In the client’s absence the advocate is expected to claim the privilege on the client’s behalf, not to give it up.

Section 132 sits in a small cluster. Section 133 extends the same duty to the advocate’s interpreters, clerks and staff. Section 134 deals with confidential communications between a person and their legal adviser and when that protection is treated as waived, for example when the client gives evidence and discloses the communication.

03Old law to new law: the mapping

Section 132 of the BSA replaces Section 126 of the Indian Evidence Act, 1872. The principle is the same. The main change is the language of who is covered.

New law (BSA, 2023)Old law (Evidence Act, 1872)Subject
Section 132Section 126Advocate cannot disclose client communications, documents or advice
Section 133Section 127Same protection for interpreters, clerks and staff of the advocate
Section 134Sections 128 and 129Confidential communications with a legal adviser, and waiver

The old Section 126 spoke of a “barrister, attorney, pleader or vakil”. Those words came from 1872 and named the categories of legal professionals of that time. Section 132 now uses the single modern term “advocate”. The substance of the protection is carried over.

04When the privilege does not apply

The protection is strong but not absolute. The proviso to Section 132 lists where it falls away.

  • Illegal purpose. A communication made in furtherance of any illegal purpose is not protected. A client cannot use a lawyer as a shield to plan a crime or a fraud.
  • Crime or fraud seen during the engagement. Any fact the advocate observes in the course of the engagement that shows a crime or fraud has been committed since the engagement began is not protected. It does not matter whether the client drew the advocate’s attention to that fact.

Two more limits matter in practice. First, the privilege covers confidences, not every fact. The identity of the client, or the fact that an engagement exists, is usually not a secret. Second, the client can waive the protection, and may do so by their own conduct, such as putting the advice in issue in a case.

The privilege protects honest legal advice. It does not cover a plan to commit a crime, because that is no longer advice the law will shield.

05The 2025 Supreme Court ruling

In 2025 the Supreme Court used Section 132 to limit how investigating agencies deal with lawyers. The Court described the privilege as one that belongs to the client and binds the advocate.

On investigations, the Court held that an investigating officer, or a station house officer running a preliminary inquiry into a cognizable offence, should not summon an advocate who represents the accused only to learn the details of the case, unless the matter falls within one of the exceptions in Section 132. The Court treated Sections 132 to 134 as meant to shield lawyers from being pressured into revealing privileged communications.

The Court also drew a line for in-house counsel. It held that a full-time in-house counsel, being an employee rather than an advocate practising in court, is not entitled to the Section 132 privilege, though the position of a legal adviser may be looked at under Section 134.

06Practical points

  • Get consent in writing before disclosing anything. If a client wants you to share a communication, record the express consent. Silence is not consent.
  • Protect the staff chain. Section 133 covers clerks and interpreters, so train your team that client files are confidential too.
  • Respond to a summons with the section, not with silence. If asked to reveal client communications, claim the privilege under Section 132 and, where relevant, cite the 2025 ruling.
  • Do not assume in-house equals privileged. After the 2025 ruling, an in-house lawyer should take advice on how Section 134 applies to their communications.

Privilege under Section 132 is argued almost entirely through case law, the proviso exceptions, waiver and the 2025 summoning ruling among them, so the real work is finding the right authorities and watching the matters where the point is live. Claw helps with both. You can search more than 30 crore judgments, from the Supreme Court since 1950 and the High Courts since 1990, to pull decisions on Section 132 and the old Section 126 in under five seconds, and you can follow orders and hearings on any live matter across 9,102 courts, benches and forums. Search by advocate name or use the all-courts case search hub to start.

A free Claw account lets you look these cases up and keep them on watch by party or advocate name. Fittingly for a privilege topic, Claw does not use customer case documents to train AI models.

09Frequently asked questions

What is Section 132 of the Bharatiya Sakshya Adhiniyam?

It is the provision that protects advocate-client privilege. An advocate cannot disclose a client’s communications, the contents of documents seen during the engagement, or the advice given, without the client’s express consent. It replaces Section 126 of the Indian Evidence Act, 1872.

Which old section does BSA Section 132 replace?

Section 126 of the Indian Evidence Act, 1872. The related protections in old Sections 127 to 129 now sit in Sections 133 and 134 of the BSA. The principle carried over, with the old list of professionals replaced by the single word advocate.

Is there a punishment under Section 132?

No. Section 132 is a rule of evidence, not an offence. It decides what an advocate can and cannot be compelled to disclose. It does not create a crime or a punishment.

When can an advocate be forced to disclose client communications?

Only in narrow cases. The proviso removes protection for communications made in furtherance of an illegal purpose, and for facts the advocate observes during the engagement that show a crime or fraud committed since it began. The client can also waive the privilege by express consent.

Does the privilege cover in-house company lawyers?

The Supreme Court held in 2025 that a full-time in-house counsel, being an employee rather than a practising advocate, is not entitled to the Section 132 privilege, though Section 134 on communications with a legal adviser may be relevant. In-house lawyers should take specific advice.

Can I track cases on advocate privilege in Claw?

Yes. Claw lets you search 30 crore+ judgments on Section 132 and old Section 126 in under 5 seconds, and track matters by party or advocate name across 9,102 courts, benches and forums, with automatic updates and alerts.
