Perpetual Confidentiality: Can an NDA Really Last Forever?

A perpetual obligation is hard to comply with rather than automatically void: you cannot keep indefinite records of everything you were told. Where perpetual confidentiality operates as a restraint on trade it also engages Section 27.

An NDA with no end date asks you to keep an obligation alive indefinitely, including after the people involved have left, the records have been archived, and nobody can remember what was disclosed. That is a compliance problem as much as a legal one.

Key takeaways

  • A perpetual obligation is difficult to comply with because you cannot maintain indefinite records of what was told to you.
  • Genuine trade secrets are a different case from ordinary business information.
  • The market structure is a defined term plus a carve-out for trade secrets.
  • India has no dedicated trade secrets statute, so the contract does the work.
  • Two to five years is the common range for general confidential information.

The practical problem

Confidentiality obligations bind an organisation, not just the person who signed. Five years after a discussion, the people who attended have moved on, the material has been archived or deleted, and there is no reliable way to know which information came from that counterparty and which came from somewhere else.

An indefinite obligation therefore asks for something that cannot really be operationalised. That is worth saying plainly to a counterparty insisting on it, because it is a practical objection rather than a legal quibble, and it usually lands better.

Trade secrets are the legitimate exception

There is a real category of information for which indefinite protection makes sense. A formula, a process, or a genuinely proprietary method retains its value precisely because it stays secret, and a fixed expiry would be arbitrary.

The distinction is between that category and ordinary business information, such as pricing from three years ago or a product roadmap that has since been superseded. Ordinary information loses commercial sensitivity over time, and an obligation that treats both the same is not calibrated to anything.

The structure that works

The formulation most commonly agreed is a defined term for confidential information generally, commonly two to five years from disclosure or from the end of the relationship, together with a clause providing that information constituting a trade secret remains protected for as long as it retains that character under applicable law.

That gives a disclosing party genuine protection for what actually needs it, and gives the receiving party an obligation it can manage. It is a standard ask and counterparties recognise it.

The Indian context

India does not have a standalone trade secrets statute. Protection rests on the contract together with established principles concerning breach of confidence, rather than on an Act defining a trade secret and prescribing remedies.

That cuts both ways in this discussion. It is a reason for a disclosing party to want a carefully drafted agreement rather than relying on a statutory baseline. It is equally a reason for a receiving party to resist an obligation drafted so broadly and so indefinitely that it cannot be complied with.

What to ask for

  • A defined term for confidential information generally, with the clock starting from disclosure or from termination.
  • A trade secret carve-out, expressed by reference to the information retaining that character.
  • A return or destruction obligation at the end of the term, so the obligation has an operational endpoint.
  • Confirmation that the exclusions apply throughout, including after termination.

Common questions

Is a perpetual NDA unenforceable in India?

It is not automatically void, and the position depends on the drafting and the information involved. The practical argument against it is that it is difficult to comply with and poorly calibrated to ordinary business information, which is usually enough to get a defined term agreed.

Our counterparty insists on perpetual. What is the compromise?

A defined term for general confidential information plus an unlimited carve-out for genuine trade secrets. That gives them indefinite protection for the category that actually needs it and gives you a manageable obligation for everything else.
