Insufficiently Stamped Documents: Consequences and Impounding (2026)
What happens when a document is under-stamped or unstamped: impounding, the penalty, and whether the court will look at it. Who acts, where, the procedure, and the appeal. Last verified October 2026.
How-to · Stamp Law · Process
If a document is not stamped, or is stamped for less than the correct duty, a court or authority will not act on it until the shortfall and a penalty are paid. Under the Indian Stamp Act, 1899, such a document is impounded under Section 33 and is inadmissible in evidence under Section 35. The deficit duty plus a penalty of up to ten times the shortfall is recovered before the document can be used. This guide sets out who acts, where, the procedure to regularise the document, and the appeal. Last verified October 2026.
- Effect: an under-stamped or unstamped document is inadmissible in evidence under Section 35 until the defect is cured.
- Impounding: the court or authority must impound it under Section 33 of the Indian Stamp Act, 1899.
- Cure: pay the deficit duty plus a penalty of up to ten times the shortfall to the Collector under Section 40; the instrument is then endorsed under Section 42 and becomes usable.
- Exception: an unstamped or under-stamped bill of exchange or promissory note cannot be validated by later payment.
01The problem in practice
You are ready to rely on an agreement in court, and the other side points out that it was signed on plain paper, or on a stamp of the wrong value. The judge stops and asks about stamp duty. This is a common and avoidable problem in Indian litigation and conveyancing.
Stamp duty is a tax on the instrument, not on the transaction. A document that does not carry the correct duty is treated as a defective instrument. Until the defect is cured, the court will not read it as evidence of its terms. The deal may be sound, but the paper cannot be used to prove it.
Why this bites late
The problem usually surfaces at the worst moment, when you tender the document in evidence or produce it before a registering or quasi-judicial authority. At that point the authority is bound to examine it and act. Fixing stamp duty early, at execution, avoids a penalty of up to ten times the shortfall later.
02What "insufficiently stamped" means
A document is insufficiently stamped when the duty paid is less than the duty chargeable on it. It is unstamped when no duty is paid at all. Both are treated as "not duly stamped" under the Act.
The duty chargeable depends on the kind of instrument (for example a conveyance, lease, agreement, power of attorney or bond) and on the Schedule that applies. Stamp duty is partly a Union subject and largely a State subject, so the rate and the exact section numbers can differ by State. Many States have their own Stamp Act or amendments to the Indian Stamp Act, 1899.
For rates and how duty is set on common agreements, see stamp duty on agreements in India.
03Impounding under Section 33
Section 33 of the Indian Stamp Act, 1899 requires certain persons to impound an under-stamped document. Every person who by law or by consent of parties has authority to receive evidence, and every person in charge of a public office (except a police officer), must examine an instrument that comes before them and impound it if it appears not duly stamped.
Impounding means the document is taken and held, and it cannot be acted upon until the duty position is set right. The authority does not destroy it. The purpose is to secure the duty the State is owed and to stop a defective instrument from being used.
The duty to examine is mandatory, not a matter of choice. The discretion on how much penalty to charge rests with the Collector, not with the officer who impounds.
04Inadmissibility under Section 35
Section 35 is the heart of the problem. It says an instrument that is not duly stamped shall not be admitted in evidence for any purpose, and shall not be acted upon, registered or authenticated by any public officer.
There is a way through. The proviso to Section 35 allows the document to be admitted once the deficit duty and the penalty are paid. In practice the court or authority can admit the instrument after the duty and penalty are made good.
One exception is strict. A bill of exchange or a promissory note that is not stamped, or is insufficiently stamped, cannot be validated by later payment of duty and penalty. For those two instruments the defect is fatal.
An unstamped or under-stamped document is not void. It simply cannot be used until the duty and penalty are paid, except for a bill of exchange or promissory note, which cannot be cured.
05How to regularise: Section 40 and the Collector
The cure runs through the Collector of Stamps. When an impounded instrument is sent to the Collector under Section 38, the Collector acts under Section 40.
- If the document is duly stamped or needs no duty, the Collector certifies that and returns it.
- If it is not duly stamped, the Collector requires payment of the deficient duty, together with a penalty. The penalty can be up to ten times the amount of the deficient duty. The Collector has the discretion to charge a smaller penalty, and in a suitable case a nominal amount.
| Step | Provision | What happens |
|---|---|---|
| Examine and impound | Section 33 | The authority impounds the under-stamped instrument |
| Send to Collector | Section 38 | The impounded instrument is forwarded to the Collector |
| Recover duty and penalty | Section 40 | Collector recovers deficit duty plus penalty up to 10x |
| Endorse and release | Section 42 | Collector endorses the instrument; it is then admissible |
Once the Collector endorses the instrument under Section 42 to show the duty and penalty are paid, it is admissible in evidence and can be acted upon as if it had been duly stamped from the start.
06Time, fees and the appeal
Who can act: the party relying on the document, who pays the deficit duty and penalty to make it usable. The impounding is done by the court or authority before which it is produced.
Where: before the court or authority where the document is tendered, and then before the Collector of Stamps for assessment of duty and penalty.
Fees: the deficient stamp duty, plus a penalty fixed by the Collector up to ten times the shortfall. There is no fixed figure for the penalty; it is set case by case.
Appeal and revision: the Collector’s decision on duty can be referred or revised. Under Section 56 the Chief Controlling Revenue Authority has control over the Collector, and under Section 57 a case can be stated to the High Court on a question of duty. State amendments also provide revision routes.
There is usually no strict limitation to pay the deficit; the document stays unusable until you do. But do it before you need the document, because the penalty and delay can be costly.

09Frequently asked questions
Is an insufficiently stamped agreement valid?
The agreement is not void, but it is inadmissible in evidence under Section 35 of the Indian Stamp Act, 1899 until the deficit duty and penalty are paid. Once you pay the shortfall and the penalty to the Collector, the document can be admitted and acted upon.
What is the penalty for an under-stamped document?
Under Section 40, the Collector can charge the deficient duty plus a penalty of up to ten times that shortfall. The exact penalty is in the Collector’s discretion and can be lower in a suitable case. Some State amendments set a different cap.
Can a court look at an unstamped document?
Not until it is regularised. The court must impound it under Section 33 and cannot admit it in evidence or act on it under Section 35. After the duty and penalty are paid and the instrument is endorsed under Section 42, the court can use it.
Can an unstamped promissory note be fixed later?
No. A bill of exchange or promissory note that is unstamped or insufficiently stamped cannot be validated by paying duty and penalty afterwards. For those two instruments the defect is fatal, which is why stamping them correctly at execution matters.
Who impounds the document?
Any person authorised to receive evidence, and any person in charge of a public office except a police officer, must examine a chargeable instrument and impound it if it appears not duly stamped. The Collector then assesses the duty and penalty.
Can I track a stamp duty dispute in Claw?
Yes. You can search a body of 30 crore+ judgments for how courts have handled under-stamped instruments and get results in under 5 seconds, then follow the orders and hearings in your own stamp dispute across the 9,102 courts, benches and forums Claw tracks.
