Inchoate Stamped Instruments under Section 20 NI Act

Updated 11 October 2026 · Fact-checked

An inchoate stamped instrument is a signed, stamped paper that is blank or incomplete. Under Section 20, the signer gives the holder prima facie authority to complete it for any amount up to the stamp cover. The signer is liable to a holder in due course for that amount, in the capacity in which he signed.

Understand Inchoate Stamped Instruments

Inchoate means incomplete. An inchoate stamped instrument is a paper that has the stamp on it and the signature of a person, but is either wholly blank or has an incomplete negotiable instrument written on it. The amount, the payee or other details may be missing.

Section 20 deals with what happens when such a paper is signed and handed over. The person who signs and delivers it gives the holder prima facie authority to make or complete a negotiable instrument on it. Prima facie means the authority is presumed on first view, and it can be challenged with proof.

There is a limit. The holder can complete the instrument for any amount specified in it, but not more than the amount covered by the stamp. If the stamp covers ₹10,000, the instrument cannot validly be completed for ₹50,000.

The signer is liable on the completed instrument, in the capacity in which he signed (maker, drawer, acceptor or indorser), to any holder in due course for the amount completed. This is so even if the holder filled in more than the signer intended, as long as it is within the stamp.

The proviso protects the signer against others. A person who is not a holder in due course cannot recover from the signer anything more than the amount the signer intended to be paid. So the protection of the signer depends on who is claiming.

Key formulas to remember

Authority of the holder: Signed + stamped + delivered (blank or incomplete) → prima facie authority to complete; The paper must be stamped as per the law on negotiable instruments then in force in India, and must be signed and delivered.
Limit on amount: Amount completed ≤ amount covered by the stamp; The holder may complete for any amount specified, but not above what the stamp covers.
Liability to a holder in due course: Signer is liable to a holder in due course for the full completed amount (within stamp); Liability is in the capacity in which the person signed.
Liability to others (proviso): Holder who is not a holder in due course: recovery ≤ amount intended by the signer; No person other than a holder in due course can recover more than the signer intended.

How to solve Inchoate Stamped Instruments questions

Use this method for any question on Section 20, whether it is a one-mark MCQ or a written fact-based question.

1Check that the paper was signed and delivered by the person, and that it is stamped. Without these, Section 20 does not apply.
2Check that it was blank or carried an incomplete negotiable instrument.
3Note the amount covered by the stamp and the amount filled in by the holder.
4If the amount filled in is within the stamp, the holder had prima facie authority. If it is above the stamp, the excess is not covered.
5Find out who is claiming: a holder in due course or not.
6If a holder in due course, the signer is liable for the full amount completed within the stamp, in the capacity in which he signed.
7If not a holder in due course, limit recovery to the amount the signer intended.
8State the conclusion with the reason in one line.

Quickest way: Three-check shortcut

When to use it: Use it in Paper 4 MCQs where an incomplete signed paper is completed by someone and you must pick the liability.

Check 1: Is it stamped and signed? If not, Section 20 fails.
Check 2: Is the amount within the stamp? Anything above the stamp is outside the authority.
Check 3: Is the claimant a holder in due course? Yes means the full amount within the stamp. No means only the intended amount.
Pick the option that matches the answers to the three checks.

Common mistakes in Inchoate Stamped Instruments

Thinking the holder can fill any amount he likes.
Students remember the authority but forget the ceiling.
Fix: Always compare the filled amount with the amount covered by the stamp.
Saying the signer is never liable if he did not intend the amount.
Students read only the proviso about intention.
Fix: Intention matters only against a holder who is not a holder in due course. A holder in due course recovers the full amount within the stamp.
Applying Section 20 to an unstamped paper.
Students focus on the blank and signature and ignore the stamp.
Fix: The section needs a paper stamped in accordance with the law on negotiable instruments then in force.
Calling the authority absolute.
The word prima facie is skipped.
Fix: Write that the authority is prima facie, meaning it is presumed and can be questioned.
Forgetting the capacity of the signer.
Students say liable without saying how.
Fix: Add that the signer is liable in the capacity in which he signed, such as maker or drawer.

Worked examples

Example 1

Ravi signs a blank paper bearing a stamp that covers ₹20,000 and hands it to Meera to make a promissory note for ₹15,000. Meera writes ₹18,000 and negotiates it to Sunil, a holder in due course. How much can Sunil recover from Ravi?

Show the solution

The paper is signed, stamped and delivered, and it was blank, so Section 20 applies.
Meera had prima facie authority to complete it for any amount up to ₹20,000, the stamp cover.
The amount ₹18,000 is within the stamp.
Sunil is a holder in due course, so Ravi is liable to him for the completed amount, as maker.

Answer: Sunil can recover ₹18,000 from Ravi.

Example 2

Anil signs and delivers a stamped blank paper, intending a note of ₹5,000. The stamp covers ₹25,000. The holder, Karan, who is not a holder in due course, completes it for ₹20,000. How much can Karan recover from Anil?

Show the solution

Section 20 applies because the paper was signed, stamped, delivered and blank.
₹20,000 is within the stamp of ₹25,000, so the completion is within the limit.
Karan is not a holder in due course.
By the proviso, a person other than a holder in due course cannot recover more than the amount intended by the signer.
Anil intended ₹5,000.

Answer: Karan can recover only ₹5,000 from Anil.

Exam tips

In MCQs, look for the words signed, stamped and blank. They point to Section 20.
Always compare the amount filled with the stamp cover before choosing an answer.
Check whether the claimant is a holder in due course. Options often differ only on this point.
In a written answer, quote the key phrases: prima facie authority, amount covered by the stamp, capacity in which he signed.
