Why an Unstamped Agreement Can Fail You in Court
Stamping is treated as a formality to be sorted out later, and later frequently means the day you need the agreement to prove something. It is the least interesting clause in Indian contracting and one of the most consequential.
Key takeaways
- Section 35 of the Indian Stamp Act, 1899 addresses instruments that are not duly stamped.
- Such an instrument is not to be admitted in evidence until the deficiency and penalty are addressed.
- Stamp duty rates are a State subject and vary considerably.
- The problem is curable, but it is cured at the point of maximum inconvenience.
- Electronic execution does not remove the stamping question.
What Section 35 does
Section 35 of the Indian Stamp Act, 1899 addresses instruments not duly stamped, providing that no instrument chargeable with duty shall be admitted in evidence for any purpose by any person having authority to receive evidence, or shall be acted upon, registered or authenticated by any such person or by any public officer, unless such instrument is duly stamped.
The section contains provisos allowing the position to be regularised, including on payment of the duty together with a penalty. So the consequence is not that the agreement is void; it is that you cannot use it to prove your case until you have paid to fix it.
Why that is worse than it sounds
The moment you need an agreement in evidence is the moment a dispute has already gone wrong. Discovering then that the document cannot be admitted until duty and a penalty are paid adds cost, delay and a poor first impression, at precisely the point you can least afford any of them.
The penalty is calculated on the deficiency and can substantially exceed the duty that would have been paid at execution. A saving of a few thousand rupees at signature turns into a materially larger sum years later, with the added cost of the delay it causes.
Rates are a State matter
Stamp duty on most instruments is a State subject, and both the rate and the mechanism vary. Some States have their own Stamp Act; others apply the 1899 Act as locally amended. Rates differ by instrument type, so an employment bond, a leave and licence agreement and a conveyance are treated differently.
This is why no article should give you a number. The rate for your instrument in your State is what matters, and it is a question for a local advocate, a company secretary, or the State stamp authority, not for a general guide.
Where it bites most often
- Rent and leave and licence agreements, which are executed constantly and stamped casually.
- Employment bonds and indemnity bonds, where the sum at stake is exactly what a dispute will be about.
- Agreements to sell and conveyances, where duty is substantial and registration is also engaged.
- LLP agreements and partnership deeds, which sit in a drawer until a partner dispute arises.
- Guarantees and powers of attorney, which are relied on precisely when relationships have broken down.
Electronic execution
Section 10A of the Information Technology Act, 2000 addresses the validity of contracts formed through electronic means, providing that such a contract shall not be deemed unenforceable solely on the ground that electronic form or means was used. Electronic execution is therefore not the problem.
What electronic execution does not do is answer the stamping question. An agreement executed electronically may still be chargeable with duty, and the mechanism for paying it varies by State. Assuming that a digitally signed document sidesteps stamping is a common and expensive error.
The practical rule
Stamp at execution, at the correct rate for your State and instrument, and keep the evidence with the agreement rather than separately. That is the whole discipline, and it costs a fraction of what curing a deficiency costs later.
Where you are signing a document someone else prepared, ask who is responsible for stamping and confirm it has been done. Silence on that point in an agreement is worth a single email, and the email is worth keeping.

Review your employment contractCommon questions
Is an unstamped agreement void in India?
Section 35 addresses admissibility rather than validity, and contains provisos allowing the position to be regularised on payment of duty and penalty. The practical difficulty is that this is discovered when you need the document, and the penalty can considerably exceed the original duty.
What is the stamp duty on my agreement?
That depends on the instrument type and the State, both of which vary considerably. Confirm it with a local advocate, a company secretary or your State stamp authority rather than relying on a figure from a general article.
We signed electronically. Does stamping still apply?
Electronic execution is addressed by Section 10A of the Information Technology Act and does not by itself remove a stamping obligation. The mechanism for paying duty on an electronically executed document varies by State and is worth confirming locally.
