Execution, Attestation and Alteration of Documents Explained

Updated 11 October 2026 · Fact-checked

Execution means signing a document, with any other formalities, so that it becomes binding on the person signing. Attestation means a witness sees the executant sign, or receives a personal acknowledgment of the signature, then signs too. A material alteration by a party without the other party's consent avoids the instrument or makes it unenforceable against the non-consenting party.

Understand Execution, Attestation and Alteration of Documents

Execution is the act of completing a document so that it takes effect. For most deeds, it means the party signs it (or puts a thumb impression or mark if unable to sign), with intent to be bound. A document that is drafted but not signed is only a draft.

Attestation is different. It is done by a witness, who sees the executant sign (or receives the executant's personal acknowledgment of the signature) and then signs the document in the executant's presence. The witness confirms that the signing happened. The witness does not become a party to the document.

The Transfer of Property Act, 1882 requires certain transfers to be made by a registered instrument that is attested. A mortgage, other than by deposit of title-deeds, where the principal money secured is ₹100 or more, can be effected only by a registered instrument signed by the mortgagor and attested by at least two witnesses. Where the principal money secured is less than ₹100, the mortgage may be made by such an instrument or by delivery of possession. A gift of immovable property must be made by a registered instrument signed by the donor and attested by at least two witnesses. Each witness must have seen the executant sign or received a personal acknowledgment, and must sign in the executant's presence. Two things are commonly confused: the witnesses need not sign at the same moment, but each must sign after seeing the executant sign or receiving from the executant a personal acknowledgment of the signature.

A document can be changed after it is written. An alteration is any change to the text. An erasure removes words. An interpolation inserts words, often between lines. Where a party to the document makes a change in a material part, such as the amount, the parties, the property or the date of payment, without the consent of the other party, the document is avoided or becomes unenforceable against the party who did not agree. For negotiable instruments, Section 87 of the Negotiable Instruments Act, 1881 states this rule. The rule is about alterations made by a party to the document, not by a stranger. Immaterial changes, such as correcting a spelling, do not have this effect.

Good practice is to avoid alterations. If a change is needed, either redraft the document or have every party initial the change in the margin, and record the correction in the attestation clause or a note. In practice, blanks should be struck through and initialled, so that nobody can add words later.

Key rules to remember

Execution: Execution = signing (or thumb mark) by the executant with intent to be bound + completion of required formalities; Signing is by the party. Witnessing is a separate act.
Attestation under Section 3, Transfer of Property Act, 1882: Attested = at least two witnesses, each having seen the executant sign or received personal acknowledgment of the signature, and each signing in the executant's presence; Witnesses need not sign together. The executant must be present when each signs.
Documents needing attestation (TPA): Gift of immovable property (Section 123) = registered instrument signed by the donor + attested by at least two witnesses. Mortgage other than by deposit of title-deeds (Section 59), principal money secured ₹100 or more = registered instrument signed by the mortgagor + attested by at least two witnesses; Where the principal money secured is less than ₹100, a mortgage may be made by such an instrument or by delivery of possession, so check the amount.
Alteration rule: Material alteration by a party without consent of the other party = instrument avoided or unenforceable against the non-consenting party (Section 87, Negotiable Instruments Act, 1881, for negotiable instruments). Immaterial alteration = no effect on validity; Material means a change affecting rights, duties or identity of parties, subject matter or amount. The rule applies to alterations made by a party, not by a stranger.
Safe practice for changes: Strike through + insert + initial by all parties in the margin + note in the attestation clause; Initials of all executants are the usual evidence of consent.

How to solve Execution, Attestation and Alteration of Documents questions

Use this order for any question on execution, attestation or alteration. It fits both theory and case-based questions.

1Identify the document and its type, such as sale deed, gift deed, mortgage deed, power of attorney or agreement.
2State what the law requires for this type: signature, attestation, stamping or registration. Keep each requirement separate.
3Check who signed, whether the signing was with intent to be bound, and whether the executant had capacity.
4Test attestation: how many witnesses, did each see the signing or receive acknowledgment, and did each sign in the executant's presence.
5Check for alterations, erasures or interpolations. Decide if they are material, and whether the other party consented.
6Apply the rule to the facts and state the conclusion on validity and effect.
7Add the practical drafting point: attestation clause, initialling and witness details.

Quickest way: Four-question check

When to use it: Use it when time is short and the question gives a short fact pattern with a signed document.

Who signed, and did the signature show intent to be bound?
Does the document type need attestation, and are there two witnesses who signed correctly?
Is there any change in the text, and is it material?
Did every affected party agree, ideally by initialling?
Write the conclusion in one line, then the fix in one line.

Common mistakes in Execution, Attestation and Alteration of Documents

Treating execution and attestation as the same thing.
Both involve signatures on the same page.
Fix: Say execution is by the party who is bound, and attestation is by a witness who confirms the signing. Use these two lines in every answer.
Saying the witness must sign at the same time as the executant, or that both witnesses must sign together.
Students remember that witnesses must be present but misread the rule.
Fix: Say each witness must see the executant sign or receive acknowledgment, and sign in the executant's presence. They need not sign at the same moment.
Saying all documents need attestation.
Students generalise from gift and mortgage deeds.
Fix: Name the ones that need it, such as gifts of immovable property and mortgages, other than by deposit of title-deeds, where the principal money secured is ₹100 or more. A mortgage below ₹100 can also be made by delivery of possession. A sale deed is governed by registration and stamping rules.
Saying every alteration makes a document void.
Overstating the rule on material alteration.
Fix: State that only a material alteration made by a party without the other party's consent avoids the document or makes it unenforceable against that party. Immaterial corrections do not.
Forgetting the practical drafting point.
Students stop at the legal rule.
Fix: Finish with the clean way to do it: strike through, insert, initial by all parties, and record in the attestation clause.

Worked examples

Example 1

Meera Iyer signs a gift deed of her house in Pune in favour of her nephew. One witness saw her sign and signed. A second person, who came later, signed as witness after Meera told him in person that the signature was hers. Both signed in Meera's presence. Is the gift deed validly attested?

Show the solution

The document is a gift of immovable property. It must be signed by the donor and attested by at least two witnesses.
Attestation requires that each witness saw the executant sign, or received from her a personal acknowledgment of her signature, and signed in her presence.
The first witness saw Meera sign and signed in her presence. This satisfies the requirement.
The second witness did not see the signing, but received Meera's personal acknowledgment and signed in her presence. This also satisfies the requirement.
The witnesses did not sign at the same moment. That does not matter, since the law does not require simultaneous signing.
Registration and stamping remain separate requirements, and the deed must also meet them to be effective.

Answer: Yes. The deed is validly attested, because both witnesses meet the test of seeing the signing or receiving acknowledgment and signing in the donor's presence. The stamping and registration requirements must still be met separately.

Example 2

Rahul Mehta and Sanjay Rao sign a loan agreement for ₹5,00,000. After signing, Rahul, the lender, changes the interest rate from 9% to 12% without telling Sanjay, and nobody initials the change. Sanjay disputes it. What is the effect, and what should have been done?

Show the solution

The interest rate is a material term, because it changes Sanjay's liability.
The change was made after execution, by one party, without Sanjay's consent.
A material alteration without the consent of the other party can make the document unenforceable against that party.
Rahul cannot rely on the altered rate against Sanjay.
The proper way was to redraft or to make the change with both parties' consent, strike through the old figure, write the new figure and have both initial it in the margin, with a note in the attestation clause.

Answer: The alteration is material and was made without Sanjay's consent, so Rahul cannot enforce the altered document against Sanjay. A consensual change should have been struck through, rewritten and initialled by both parties.

Exam tips

Define execution and attestation in two separate lines, because examiners often ask for the difference directly.
For attestation, give the three elements: two witnesses, who saw the signing or received acknowledgment, and signed in the presence of the executant.
Name the document types where attestation is mandatory under the Transfer of Property Act, 1882, and state that other documents may only need registration or stamping.
In case questions, split the answer into material and immaterial alteration, and ask whether the other party consented.
Close each answer with a drafting point, such as an attestation clause with witness names and addresses, or margin initials for corrections.

Practice questions from Types of Documents

Execution, Attestation and Alteration of Documents: frequently asked questions

What is the difference between execution and attestation?

Execution is signing by the party who is bound, with intent to be bound. Attestation is signing by a witness to confirm that the executant signed or acknowledged the signature. The executant is bound by the document, but the witness is not.

How many witnesses are required to attest a document?

Where the law requires attestation, as for a gift of immovable property or a mortgage not made by deposit of title-deeds where the principal money secured is ₹100 or more, at least two witnesses are required. A mortgage below ₹100 can also be made by delivery of possession. Each witness must have seen the executant sign or received a personal acknowledgment, and must sign in the executant's presence.

Does an alteration make a document void?

Not always. A material alteration made by a party without the consent of the other party avoids the document or makes it unenforceable against the non-consenting party. For negotiable instruments, Section 87 of the Negotiable Instruments Act, 1881 applies. An immaterial change, such as correcting a spelling, does not affect validity.

How should corrections be made in a deed?

Avoid them if you can and redraft instead. If a correction is needed, strike through the old words, write the new words and have every party initial the change in the margin. Note it in the attestation clause.
