Is an NDA enforceable in India?

Yes. A non-disclosure agreement is an ordinary contract under the Indian Contract Act, 1872 and is enforceable if the usual requirements are met. Remedies include damages and, more practically, an injunction under the Specific Relief Act, 1963 to restrain threatened or continuing disclosure. Enforcement in practice depends heavily on being able to prove what was disclosed, when, and that it was confidential.

How long should an NDA last?

It depends on the information. Commercial information with a short shelf life is adequately protected by a two to five year term. Trade secrets, algorithms, source code and formulations should be protected for as long as they remain secret, because a fixed expiry hands the recipient a date on which they become free to use them. Many agreements sensibly use a general term with a longer carve-out for trade secrets.

Do I need an NDA before every business conversation?

No, and insisting on one can slow down early discussions unnecessarily. An NDA is worth having before disclosing genuinely non-public commercial, technical or financial information — diligence material, product roadmaps, pricing structures, customer data or unpublished IP. For a first exploratory conversation held at a general level, it is usually disproportionate.

Contracts

What is an NDA and when do you need one?

A non-disclosure agreement is a contract under which one or both parties agree to keep specified information confidential and to use it only for an agreed purpose. It is governed in India by the Indian Contract Act, 1872. A workable NDA defines confidential information and its exclusions, states the permitted purpose, restricts onward disclosure, sets the duration of the obligation, and provides for return or destruction of material on termination.

Key takeaways

The permitted-purpose clause matters as much as the confidentiality obligation itself.
Standard exclusions — public domain, independently developed, lawfully received — are essential.
Trade secrets should be protected for as long as they remain secret, not for a fixed term.
An NDA does not assign intellectual property; that needs a separate provision.

Relevant law and authority

Indian Contract Act, 1872: Governs the formation and enforceability of the agreement.
Specific Relief Act, 1963: Injunctive relief to restrain a threatened or continuing disclosure.
Copyright Act, 1957: Relevant where the disclosed material is itself a protected work.
Digital Personal Data Protection Act, 2023: Applies where the confidential information includes personal data.

The clauses that do the work

The definition of confidential information sets the scope. A definition covering everything disclosed, in any form, is common but should be paired with a marking or confirmation mechanism for oral disclosures so there is no dispute later about what was covered.

Exclusions are standard and important: information already public, already known to the recipient, independently developed without use of the disclosure, lawfully received from a third party, or required to be disclosed by law or regulation, usually with a notification obligation.

The permitted purpose limits use, not just disclosure. Without it, a recipient could argue it was entitled to use the information for its own competing purpose so long as it did not tell anyone.

Duration and survival

Commercial NDAs commonly run confidentiality obligations for two to five years from disclosure. That is often the wrong answer for genuine trade secrets, source code or formulations, which should be protected for as long as they remain secret.

Return or destruction obligations should account for backup systems and regulatory retention, since a blanket destruction promise is frequently impossible to perform honestly.

What an NDA does not do

An NDA does not transfer ownership of anything. If a discussion is likely to produce jointly developed material, the IP position needs a separate clause or a separate agreement.

It also does not prevent independent development. Where that is a real commercial concern, a residuals clause, a non-solicitation provision or a formal collaboration agreement is the appropriate instrument rather than a broader confidentiality definition.

Practical implications

Decide whether the NDA needs to be mutual or one-way before drafting.
Set a longer or indefinite term for true trade secrets.
Include a permitted-purpose clause, not just a non-disclosure obligation.
Carve out disclosure compelled by law, with notice to the disclosing party.
Address personal data expressly if any is likely to be shared.
