E-stamp paper — what stamp duty actually buys you, why an unstamped document cannot be shown in court, and the ruling that stamp paper never expires

What stamp duty actually is

Stamp duty is a tax on a document. Not on the transaction, not on the parties, not on the money that changes hands — on the instrument. That distinction sounds academic until it starts deciding cases, which it does constantly.

The Indian Stamp Act, 1899 sets out which instruments are chargeable and at what rate, and the rates applicable within a State are fixed by that State. An instrument is chargeable because of what it does, not because of what it is called. A document headed “Memorandum of Understanding” which in substance creates a lease is charged as a lease. A document headed “Agreement to Sell” which in substance transfers possession and consideration may attract duty as a conveyance. The heading is the last thing anybody looks at; the operative clauses are the first.

This is worth internalising before you buy anything, because the commonest expensive error in this area is not forgetting to stamp a document. It is stamping it as the wrong kind of document, cheaply, and discovering the real classification years later when somebody produces it in a dispute.

There is a second reason the distinction matters. Because the duty attaches to the instrument, it does not disappear if the transaction falls through, and it is not reduced because the parties are family, because no money changed hands on the day, or because everybody involved trusts everybody else. The document exists; the charge exists. The only question is whether it has been paid.

Judicial, non-judicial, and why court fee is a different tax

Older documents and older people talk about “judicial” and “non-judicial” stamp paper as though they were two grades of the same thing. They are not; they belong to two different statutes and answer two different requirements.

The practical consequence: if a court has directed you to make good a deficiency in court fee, buying a non-judicial e-stamp does not answer it, and the reverse is equally true. People lose dates over this. Read the order, note which statute it names, and pay under that one.

Why Delhi stopped selling stamp paper

Physical stamp paper had three chronic problems. It could be counterfeited, and was, on a scale large enough to produce one of the country’s better-known frauds. It could be hoarded and resold at a premium whenever a denomination ran short at the vendor. And it left no central record, so the only proof that duty had been paid was the piece of paper itself — which meant that losing the paper could mean losing the proof.

Electronic stamping answers all three. The certificate is generated against a central record, so it can be verified by anyone holding the number; the denomination is whatever you need rather than whatever the vendor happens to have; and the record survives the loss of the printout. Delhi moved to e-stamping and phased out physical non-judicial stamp papers, which is why a Delhi transaction today almost always means an e-stamp certificate rather than a sheet of stamp paper.

There is one consequence people find inconvenient, and it is deliberate: because every certificate is centrally recorded with its date, the date on your stamp is now checkable by the other side, by the registrar, and by a court. That is a feature rather than a defect, and it is the reason the back-dating question below has such a short answer.

How an e-stamp certificate is produced

The mechanism is worth understanding, because it explains exactly what can and cannot be changed afterwards.

A central record keeping agency maintains the system for the State. Duty is collected through authorised collection centres — commonly banks, and counters at or near sub-registrar offices — which enter the particulars and generate the certificate. Those particulars are the ones that matter: the amount of duty, the description of the instrument, the first party, the second party, the person on whose behalf the duty is being paid, and the date. The system then issues a certificate carrying a unique identification number.

Everything on that certificate is fixed at generation and recorded centrally. You cannot later change the parties, the description or the date on a certificate that has already been issued. If any of those were entered wrongly, the answer is not correction fluid; it is a fresh certificate and, where the first was never used, a refund claim for the unused one. Which is why five minutes of care at the counter is worth more than any amount of argument afterwards.

Section 17 — before or at the time of execution

The timing rule is short and absolute. Section 17 of the Indian Stamp Act provides that all instruments chargeable with duty and executed by any person in India shall be stamped before or at the time of execution.

Not afterwards. Not when the document is first needed. Not when a dispute starts. The duty attaches at execution, and a document executed on unstamped paper is, from that moment, an instrument that is not duly stamped — with all the consequences set out in Section 35.

This is the provision that people unknowingly ask us to break when they ask for a stamp certificate dated last March for an agreement signed last March. The honest answer, and the one that keeps the document usable, is below.

Section 35 — the penalty that is not a fine

If you read only one provision of the Act, read this one.

Read the three verbs. Admitted in evidence. Acted upon. Registered or authenticated. Each is a separate disability, and each one is fatal in a different situation.

• Admitted in evidence — you cannot prove the agreement in court by producing it. If your case rests on the document, the case does not get off the ground.
• Acted upon — a public officer cannot give effect to it. This reaches far beyond courts, into every office where a document is presented in order to obtain something.
• Registered or authenticated — the sub-registrar cannot register it. A transaction that legally requires registration therefore cannot be completed at all.

Notice what Section 35 does not say. It does not say the agreement is void. It does not say the parties owe each other nothing. It says the instrument cannot be used. That distinction is the subject of the 2023 judgment below, and it is why an unstamped document is a serious problem rather than a terminal one.

The ten-times cure

The Act provides its own remedy, in the first proviso to Section 35. An instrument that is not duly stamped may be admitted in evidence on payment of the duty with which it is chargeable, together with a penalty of five rupees, or, where the deficit portion of the duty exceeds five rupees, a penalty of a sum equal to ten times such duty or portion.

Ten times the shortfall. Not ten per cent — ten times. On a small affidavit that is a trivial sum. On a lease or a conveyance where the correct duty ran to lakhs and the document was stamped as a simple agreement, it is the kind of number that ends transactions.

The lesson is not that the penalty is harsh. It is that the penalty is payable at the worst possible moment. Nobody discovers a stamping defect on a quiet afternoon. They discover it when the registrar refuses the document, or when the other side’s counsel takes the objection — which is precisely when you have the least room to negotiate anything at all.

The promissory note that can never be cured

The second proviso to Section 35 carves out an exception with real teeth: the curing facility does not apply to a bill of exchange or promissory note.

An unstamped promissory note cannot be saved by paying duty and penalty later. It is inadmissible, and it stays inadmissible. For a lender relying on a promissory note as the record of the debt, that is the whole security gone — not reduced, gone.

We raise this on a page about e-stamping because the people most likely to be caught are precisely the people least likely to be reading about stamp duty: a friend lending to a friend, a small trader taking a note from a customer, a family advancing money against a written promise. The duty on a promissory note is small. The cost of skipping it is total.

Section 33 — impounding is a duty, not a choice

People sometimes assume that a sympathetic official can overlook a stamping defect. The Act removes that possibility deliberately.

Section 33 provides that every person having by law or consent of parties authority to receive evidence, and every person in charge of a public office before whom any instrument chargeable with duty is produced or comes in the performance of his functions, shall, if it appears to him that the instrument is not duly stamped, impound it.

Impounding means the instrument is taken and sent for determination of the duty and penalty. The officer is not exercising discretion; he is discharging an obligation. That is why a sub-registrar cannot quietly register a short-paid document as a favour, and why producing an unstamped document in a proceeding can mean losing possession of it as well as losing the point.

Section 31 — adjudication before you sign

There is a provision in the Act designed for exactly the situation where you genuinely do not know what the correct duty is, and hardly anybody uses it.

Section 31 allows an instrument, whether executed or not, to be brought to the Collector, with an application and the prescribed fee, for the Collector to determine the duty with which it is chargeable. Section 32 then provides for a certificate endorsing that determination, and an instrument so certified is treated as duly stamped.

What you are buying is certainty. On a document of any size — a long lease with a premium and a rent, a family arrangement, a development agreement, a deed with mixed operative parts — the difference between two possible classifications can run into very large numbers, and the ten-times penalty applies to the gap. An adjudication removes the argument before it can be had.

It is slower than walking up to a counter, and it costs a fee. On a small agreement it is not worth it. On anything where you would be genuinely unhappy to be told, years later, that you stamped it as the wrong instrument, it is the cheapest insurance in the Act.

Section 29 — who pays

Disputes about who bears the duty are common and almost always avoidable, because the Act’s rule is a default rather than a command.

Section 29 allocates the expense of providing the proper stamp in the absence of an agreement to the contrary. Under that default, taking the two situations people ask about most, the duty on a conveyance falls on the grantee — the buyer — and the duty on a lease or an agreement to lease falls on the lessee.

Because the section yields to agreement, the only sensible practice is to write the allocation into the document. One line saying who pays the stamp duty and who pays the registration fee removes an entire category of argument on the day of registration, when neither side has any appetite for it.

Does stamp paper expire? The 2008 answer

This is the most persistent myth in Indian documentation, and the Supreme Court dealt with it squarely.

So a document written on stamp paper bought two years ago is not defective for that reason. If a counter tells you otherwise, this is the answer, and it has been the answer since 2008.

Two qualifications, both practical rather than legal. First, the ruling concerns the validity of the paper, not the sufficiency of the duty — old paper of the right value is fine, old paper of the wrong value is still under-stamped. Second, with an e-stamp the date sits in a central record that anybody can check, so a long gap between the certificate date and the execution date does not make the document invalid, but it does invite a question about when the document was really signed. If there is an innocent explanation, have it ready.

Why an e-stamp cannot be back-dated

We are asked for this several times a week, almost always for a rent agreement, and almost always for an understandable reason: the tenancy started in April, it is now August, and somebody — a bank, an employer, a school, a police verification — has asked to see the agreement.

It cannot be done, and the reason is structural rather than a matter of willingness. The certificate is generated with the date it is issued, and that date is written to a central record at the moment of generation. Any person to whom you show the certificate can verify that record. A certificate purporting to bear an earlier date is therefore not a clever solution; it is a discrepancy that announces itself to the first person who checks.

The lawful routes for a document that has already been executed are the ones the Act itself provides: pay the duty with the penalty under the proviso to Section 35, or have the instrument adjudicated under Section 31. Both are unglamorous. Both leave you holding a document you can actually use.

The 2023 seven-judge ruling on unstamped agreements

For several years there was a genuine and unresolved question in Indian law: if a contract containing an arbitration clause is unstamped, is the arbitration clause itself unenforceable? The answer moved more than once, and in 2023 a Constitution Bench settled it.

Why this matters far beyond arbitration: it is the clearest modern statement of the distinction this whole page turns on. A stamping defect attacks the usability of the document, not its existence. The contract is still a contract. The obligations are still obligations. What you have lost, until you cure it, is the right to put the paper in front of a court or an officer and have them act on it.

That is worth knowing if you are ever on the receiving end of an argument that your agreement is “void because it is not stamped”. It is not void. It is inadmissible, and inadmissibility is curable — expensively, but curable.

Stamp duty is not the registration fee

These are two separate payments under two separate statutes, and they are routinely conflated — usually to the buyer’s surprise on the day.

Which documents must be registered is a separate question with its own answer, and we have set it out where it belongs rather than repeating it here — the lease position is covered in our leave and licence guide and the practical Delhi routine in the rent agreement guide.

Getting the amount right

Three things decide the number, in this order.

• What the instrument is in substance. Not its title. An instrument is charged according to the article of the schedule it truly falls under. Where a document does several things at once, this can be genuinely difficult, and it is the classic case for adjudication under Section 31.
• The value, where value matters. For instruments relating to immovable property the duty is computed on the consideration or on the value fixed by the State’s circle rate schedule, whichever is higher. Writing a lower figure into the document does not reduce the duty; it merely creates a mismatch the registering officer is required to notice.
• The State. Rates are set State by State, and several States give a concession on instruments in favour of women. Because these rates are revised by notification from time to time, we deliberately do not print a rate table on this page that would be wrong within a year. We confirm the current figure for your instrument before anything is bought, and you see the certificate with the amount on it.

Verifying a certificate, and spotting a bad one

Every e-stamp certificate carries a unique identification number, and that number can be checked against the central record. The check returns the particulars: amount, date, description, and the parties. It takes under a minute.

Do it in three situations especially.

• When somebody hands you a ready-made agreement. Most often a rent agreement, already printed on a stamp certificate that you did not buy. Check that the parties and the amount match what you are about to sign.
• When the stamp was bought by the other side. The person who pays chooses what to declare. Verify rather than assume.
• When the certificate looks like a photocopy of a photocopy. The certificate carries a number for exactly this reason. Use it.

If the number does not verify, or verifies with a different amount, a different description or different parties, stop and ask why before signing anything. That mismatch is not a clerical curiosity; it decides whether the document you are about to sign is stamped at all.

Lost, spoiled and unused certificates

Three different situations with three different answers.

• Lost printout, stamp already used on a document. The central record still holds the entry against the identification number. This is the easiest of the three, and it is one of the real advantages of e-stamping over paper.
• Bought but never used. Section 54 provides for a refund on unused stamp paper where the claim is made within six months, subject to the prescribed conditions and the deduction the rules allow. This is the provision that gave rise to the expiry myth, and it is all the six-month period ever meant.
• Spoiled — wrong particulars, or an abandoned transaction. The Act contains its own machinery for spoiled stamps, with its own conditions and time limits. Act quickly; these remedies are time-bound, and a certificate left in a drawer for a year is usually beyond help.

Franking, and when you would still use it

Franking is payment of duty by impressing the document itself with a stamp, done by an authorised agent — typically a bank — on payment of the amount. It is a legitimate mode of paying duty, not a lesser one.

E-stamping has largely displaced it for everyday documents because the central record makes verification trivial. But franking is still used, it is still accepted where it is available, and for some instruments and some offices it remains the practical choice. The only question worth asking is which mode the office receiving your document will accept, and that has a definite answer rather than being a matter of preference.

We provide franking alongside e-stamping for that reason. Tell us the document and where it is going, and we will tell you which one to use.

Which of your documents needs what

Stamp duty sits underneath almost every document on this website. This table is a map of where this page connects to the rest of them.

Order e-stamp assistance — free, pay after work

Where these go wrong

• Stamping by the title of the document. The schedule charges by substance. A document called an agreement which operates as a lease is charged as a lease, and the difference surfaces at registration or in a dispute.
• Signing first, stamping later. Section 17 requires stamping before or at execution. Reversing the order converts a routine payment into a penalty exposure.
• Names on the certificate that do not match the document. A misspelt party or a wrong first-party field is the most common objection at the registration counter, and it cannot be corrected on the certificate itself.
• Believing the six-month myth. Stamp paper does not expire. People discard valid paper, or accept a refusal that the 2008 judgment answers.
• Asking for a back date. The date is centrally recorded. The request creates a worse problem than the one it was meant to solve.
• Leaving a promissory note unstamped. The one defect in this area with no remedy at all.
• Under-stating consideration to save duty. Duty is charged on the circle rate where that is higher, so nothing is saved and the mismatch is permanent.
• Assuming the registration fee is included. Two statutes, two payments. Budget for both.
• Paying non-judicial duty when the court asked for court fee. Different Act, different payment, lost date.
• Not verifying a certificate handed to you. A minute’s check against the central record, before signing, answers a question you cannot ask afterwards.

Time and cost

An e-stamp certificate for an ordinary document is a same-day matter. What takes time is not the generation of the certificate but the two decisions before it: what the instrument really is, and what the duty on it therefore comes to. On a simple affidavit or agreement those take minutes. On a property instrument, or anything with mixed operative parts, they deserve proper attention and sometimes deserve adjudication.

We do not mark up stamp duty. It is a government levy, you see the certificate with the amount on it, and our charge is stated separately. Nothing is payable in advance — placing an order is free, we call you with the exact duty and the final figure, and payment comes after the work is done.
