TL;DR: An affidavit is a written statement of facts sworn before an authorised officer, and its validity turns on four things: the deponent identifies which facts are within personal knowledge and which are believed on information, the verification clause states this split honestly, an authorised person attests it, and stamp duty is paid where the state’s law requires it. Get any of these wrong and a registry can return the affidavit or a court can discount it.

What an affidavit is, and how it differs from a declaration

An affidavit is a written statement of facts that the person making it, the deponent, swears or affirms is true, before someone legally authorised to administer that oath. The oath or affirmation is what separates it from an ordinary written declaration. A declaration you sign and hand over is just your assertion. An affidavit is your assertion made under a legal sanction: if the statement is false, the deponent can be prosecuted for perjury. That sanction is the entire reason courts, registries, and government departments ask for an affidavit rather than a plain letter.

This also means an affidavit is not automatically “evidence” in the technical sense. The Supreme Court settled this in Sudha Devi v M.P. Narayanan, decided on 26 April 1988, holding that affidavits are not included in the definition of evidence in Section 3 of the Evidence Act, and can be used as evidence only if, for sufficient reason, the court passes an order under Order XIX Rules 1 or 2 of the Code of Civil Procedure. In plain terms: filing an affidavit does not by itself make its contents proved facts. A court has to decide to receive it as evidence, or a specific statute has to say it stands as evidence for that proceeding.

If your immediate task is not an affidavit but a response to correspondence, that document does not need an oath at all; see how to reply to a legal notice for that separate drafting exercise, and how to draft a legal notice for the sender’s side of the same document. If you are filing a written statement in a suit, its verification clause is governed by different CPC provisions from the ones covered here; that is addressed in written statement and the limitation period under CPC.

Where the requirement comes from

Three statutes govern affidavits in India, and they do different jobs.

The Code of Civil Procedure 1908 is the primary source for civil matters. Order XIX Rule 1 lets a court, “for sufficient reason,” order that a particular fact be proved by affidavit or that a witness’s affidavit be read at the hearing, subject to a proviso: if a party genuinely wants a witness produced for cross-examination and that witness can be produced, the court will not allow that witness’s evidence to be given by affidavit alone. Order XIX Rule 2 permits evidence by affidavit on any application, but lets the court order the deponent’s attendance for cross-examination at either party’s instance, and that attendance is to be in court unless the deponent is exempt or the court directs otherwise. Order XIX Rule 3(1) fixes the content rule that most affidavit drafting mistakes violate: affidavits must be confined to facts the deponent is able of their own knowledge to prove, except on interlocutory applications, where statements of belief are admissible provided the grounds for that belief are stated. You can read the operative Order XIX text as reproduced and applied by the Andhra Pradesh High Court in Nadella Estate Pvt Ltd v Prema Ravindranath.

The Bharatiya Sakshya Adhiniyam 2023 (BSA), which replaced the Indian Evidence Act 1872 with effect from 1 July 2024, carries forward a rule that surprises people who assume the Evidence Act governs affidavits: it does not. Section 1 of the BSA states that the Act applies to all judicial proceedings before a court, “but not to affidavits presented to any Court or officer, nor to proceedings before an arbitrator.” This is the same exclusion the old Evidence Act carried in its own Section 1. An affidavit is a creature of procedural law, not of the law of evidence, until a court decides to treat it as evidence under a specific procedural provision.

Criminal proceedings have their own route. The Bharatiya Nagarik Suraksha Sanhita 2023 (BNSS), which replaced the Code of Criminal Procedure 1973, carries forward the old Section 296 CrPC provision on evidence of a formal character given by affidavit, now at BNSS Section 332. This lets certain classes of witness, typically ones giving formal or technical evidence rather than disputed facts, testify by affidavit instead of appearing in person, while preserving either party’s right to have the deponent summoned for cross-examination. The Madhya Pradesh High Court traced this correspondence directly in Sunil Agrawal v Nitin Kumar Badhwani, decided 24 February 2026.

The anatomy of a valid affidavit

Every properly drafted affidavit has the same skeleton, whichever court it is going to.

Cause title. If the affidavit is filed in a pending case, it carries the same cause title as that case: the court’s name, the case number, and the parties as arrayed in the main proceeding, followed by a heading such as “Affidavit of [deponent’s name].” If there is no pending case, for example an affidavit made for a passport application or a name change, the heading simply identifies the deponent and the purpose.

Deponent identification. The opening paragraph names the deponent in full, states their parentage or spouse’s name, age, occupation, and residential address, and, where the deponent is a party to a proceeding, their status in that proceeding (plaintiff, respondent, and so on). A deponent who cannot be traced back to a real, identifiable person defeats the entire purpose of swearing an oath.

The numbered paragraph body. Facts are set out one to a paragraph, numbered sequentially, in the deponent’s own voice (“I say that…”, “I state that…”). This is not a stylistic preference; a numbered body is what lets a verification clause refer back to specific paragraphs, and it is what lets an opposing party or the court respond to individual assertions rather than an undifferentiated narrative.

The verification clause and jurat, covered in the next two sections, close the document.

Exhibits. Where the affidavit refers to a document, whether a contract, a notice, or a certificate, that document should be physically annexed and marked as an exhibit (Annexure A, B, and so on), with the affidavit’s text cross-referencing the exhibit by that mark. A document merely described in the body but not annexed is a common source of objection.

An affidavit built on this skeleton is close in spirit to a witness statement in other procedural documents you may already be drafting, such as a writ petition or a caveat petition, both of which are typically accompanied by a supporting affidavit built the same way.

The sequence from drafting to a filed, accepted affidavit runs the same way regardless of the forum:

Personal knowledge versus information and belief

This is the distinction Order XIX Rule 3(1) makes, and it is the single most consequential drafting decision in an affidavit.

A fact is within personal knowledge when the deponent directly perceived it: they were present, they signed the document, they received the payment, they witnessed the event. These facts can be stated flatly: “I say that on 12 March 2026, I personally handed over the sum of Rs 5,00,000 to the respondent at his office.”

A fact is known only on information and belief when the deponent learned it from someone else, a document, or a record, rather than directly. Order XIX Rule 3(1) permits this only on interlocutory applications, and only if the affidavit states the grounds for that belief, meaning it names the source. “I am informed by my accountant, Mr X, and verily believe, that the outstanding amount as per the company’s books is Rs 5,00,000” is the correct form. A bare assertion of the same fact without naming Mr X, or without saying it comes from the books at all, does not meet the rule.

Mixing the two without marking which is which is the error the Supreme Court criticised in State of Bombay v Purushottam Jog Naik, decided 26 May 1952. The affidavit in that case set out facts that were plainly within the Home Secretary’s own knowledge, but the verification clause blanket-stated that everything was “true to the best of his information and belief.” The Court held that verifications should invariably be modelled on Order XIX Rule 3, and that where a matter deposed to is not based on personal knowledge, the source of the information must be clearly disclosed, warning that slipshod verifications of this kind can lead to the affidavit being rejected outright.

The verification clause and the jurat

These are two separate things that get run together in practice, and each has its own function.

The verification clause is the deponent’s certificate about the content of their own affidavit. It typically reads: “I, the deponent above named, do hereby verify that the contents of paragraphs 1 to 4 are true to my personal knowledge, and the contents of paragraph 5 are based on information received from [source] and believed by me to be true, and that nothing material has been concealed therefrom.” Because of Purushottam Jog Naik, a verification clause that lumps every paragraph into “true to the best of my knowledge and belief” without this split is defective, regardless of how well the body paragraphs are written.

The jurat is the attesting officer’s certificate, placed after the deponent’s signature, recording that the affidavit was sworn or affirmed before them, on a stated date, at a stated place. A jurat typically reads: “Solemnly affirmed at [place] on this [date] by the deponent, who is identified to me by [means of identification].” Beneath it, the attesting officer signs, adds their seal or stamp, and, if a notary, their registration number. A signed affidavit without a completed jurat is not an affidavit at all; it is an unsworn statement, which defeats the perjury sanction that gives the document its legal weight in the first place.

Who can attest an affidavit, and where

Section 8(1)(e) of the Notaries Act 1952 gives a notary the power to “administer oath to, or take affidavit from, any person,” a function the Delhi High Court set out in full in Baker Oil Tools (India) Pvt Ltd v Baker Hughes Ltd, decided 3 June 2011, alongside the notary’s other functions of verifying, authenticating, certifying, or attesting instruments. A notary public is therefore a valid attestor for an Indian affidavit anywhere in the country, and is the most commonly used option outside a pending court proceeding.

Where an affidavit is being filed in a pending case, most courts also run their own oath commissioner system: advocates on the court’s own panel, authorised under rules the High Court frames for that purpose, who can attest affidavits filed in that court without the deponent going to an outside notary. Which system a given registry expects, its own panel commissioner or an outside notary, is a matter of that court’s or tribunal’s own filing rules, and it is worth confirming before the deponent signs anything, since an affidavit attested by the wrong category of officer for that forum can be returned on that ground alone.

For a deponent located outside India, most Indian missions abroad can attest an affidavit through their consular officers, and a locally notarised affidavit is often accepted subject to that court’s own rules on foreign attestation and, where applicable, apostille or consular legalisation. This is the same practical issue that comes up with powers of attorney executed abroad and with a vakalatnama signed by a client who cannot attend in person: confirm the specific court’s requirement rather than assuming national practice is uniform.

Stamp duty: when it applies and when it does not

Stamp duty on documents is largely a state subject in India. The Indian Stamp Act 1899 lists “Affidavit” as a chargeable instrument in its central Schedule I, but individual states have amended that schedule or enacted their own Stamp Acts, so whether a given affidavit needs to be executed on stamp paper, and at what value, depends on where it is being filed, not on a single national figure. This piece deliberately does not quote a rupee amount for any state; check the current schedule for the state where the affidavit will be filed, or ask the registry, before buying stamp paper.

A useful working distinction: affidavits filed in ongoing court proceedings, in support of an interlocutory application or in reply to one, are commonly accepted on plain paper in many registries, because the court fee and process already attach to the main proceeding. Affidavits made for a standalone purpose outside a pending case, a name change, an address proof, a lost-document declaration, an affidavit accompanying a registered deed, are more likely to require stamp paper of a value fixed by the state’s own schedule. Neither rule is universal. Some High Courts and quasi-judicial forums insist on stamped affidavits even for interlocutory applications; some states exempt certain categories entirely. The only reliable step is to check the current position for the specific state and forum before the deponent signs, exactly as with the gazette and identity-document formalities around a name change, where the affidavit is usually the first document in the chain and its stamping requirement is set at the state level.

The defects that get affidavits rejected or disbelieved

Registries reject affidavits on filing for procedural defects. Courts discount or disregard affidavits later for substantive ones. Both categories recur often enough to be predictable.

ElementCompliantDefective
Verification clause✓ States which paragraphs are true to personal knowledge and which are based on information, naming the source✗ Blanket “true to the best of my knowledge and belief” with no split, the defect condemned in Purushottam Jog Naik
Deponent identification✓ Full name, parentage or spouse’s name, age, and address stated in the opening paragraph✗ Deponent’s identity appears only in the signature block, not in the body
Paragraph structure✓ Numbered paragraphs, one fact per paragraph✗ Unnumbered narrative blocks mixing several facts and dates together
Jurat✓ Complete: place, date, attesting officer’s signature, seal, and registration number where applicable✗ Deponent’s signature present but no attestation, or attestation without a seal or stamp
Exhibits✓ Every document referred to is physically annexed and marked, and the text cross-references the mark✗ A document is described as “annexed herewith” but is not actually attached
Stamp dutyFollows the filing state’s stamp schedule for that category of affidavitFiled on plain paper in a state or forum where a stamped affidavit is mandatory for that category
Belief without grounds✓ States the source of information for any fact not within personal knowledge✗ States a fact “on information and belief” without saying whose information, violating Order XIX Rule 3(1)

Two of these deserve emphasis because they are the ones that survive drafting and only surface at hearing. First, an affidavit that mismatches its own body and verification, facts that read as first-hand knowledge in the paragraphs but are verified as “information and belief,” or the reverse, invites exactly the objection raised in Purushottam Jog Naik. Second, an affidavit sworn to support a legal argument that cites case law is only as reliable as the citations inside it; an affidavit that quotes a judgment that has since been overruled, or attributes a holding to the wrong bench, damages the deponent’s credibility along with the argument. Checking that a cited authority is still good law before it goes into a sworn document is exactly the kind of verification step a citator is built for. Niyam’s good-law checking flags an overruled or distinguished authority before the affidavit is finalised, which is a cheaper place to catch the error than at the hearing; see how good-law checking works for what that process involves.

Affidavits in specific contexts

In support of an interim application. Applications for interim relief, stay, injunction, or interim maintenance are almost always accompanied by an affidavit setting out the facts urgency depends on: why the relief cannot wait for the final hearing, and what harm follows if it is refused. Because interim applications are exactly where Order XIX Rule 3(1) permits statements on information and belief (with grounds stated), this is where the personal-knowledge-versus-belief distinction gets tested most often. An affidavit in support of an anticipatory bail application or a stay sought in a writ petition follows this same structure.

In reply. A reply affidavit responds paragraph by paragraph to the affidavit it answers, admitting what is admitted, denying what is denied, and adding any new facts the respondent wants on record. A reply that does not track the numbering of the affidavit it answers, responding in a general narrative instead, is harder for the court to match against the original assertions and often draws a direction to refile in proper form.

Evidence on affidavit. Under Order XVIII of the CPC as amended, examination-in-chief in civil trials is commonly taken on affidavit rather than read out orally in court, with cross-examination still conducted live; the mechanics of that shift are covered in CPC civil procedure basics. Here the affidavit functions as a witness’s sworn testimony, which is why Order XIX Rule 2’s cross-examination safeguard matters in practice: a party who wants the deponent tested on their statement can insist on it, and the court cannot treat the affidavit as unchallenged proof if that demand is refused.

The assets-and-liabilities affidavit in maintenance matters. The Supreme Court’s judgment in Rajnesh v Neha, Criminal Appeal No. 730 of 2020, decided 4 November 2020, directs both parties in every maintenance proceeding across the country to file a standardised Affidavit of Disclosure of Assets and Liabilities within four weeks of the first hearing, covering income from all sources, movable and immovable assets, and existing liabilities, with an adverse inference available against a party who files an incomplete or false one. This affidavit follows the same drafting rules as any other, numbered paragraphs, honest verification, proper attestation, but its content is fixed by the format the judgment annexed rather than left to the drafter. The fuller mechanics of how that affidavit feeds into a quantum calculation are set out in maintenance and alimony calculation in India, and the BNSS route for interim maintenance specifically is covered in maintenance under BNSS section 144.

Affidavits also recur in mutual consent divorce petitions, in consumer complaints filed on e-Daakhil, in applications supporting a contempt petition, in an application seeking condonation of delay where the affidavit is the document explaining the delay itself, and in succession certificate and legal heir certificate applications. The format does not change across these; only the facts being sworn to do.

Frequently asked questions

An affidavit is sworn or affirmed before a person legally authorised to administer an oath, which exposes the deponent to perjury consequences for a false statement. A plain declaration is simply signed by the person making it, with no oath and no attesting officer. Courts and registries ask specifically for an affidavit, not a declaration, whenever they need the extra legal weight the oath provides.

Is an affidavit automatically treated as evidence in a case?

No. The Supreme Court held in Sudha Devi v M.P. Narayanan (1988) that affidavits are not evidence within the meaning of Section 3 of the Evidence Act, and can be used as evidence only if the court passes an order under Order XIX Rules 1 or 2 of the CPC for sufficient reason, or a specific statute directs that they be treated as evidence for that proceeding.

Does the Bharatiya Sakshya Adhiniyam 2023 govern affidavits?

No. Section 1 of the BSA, which replaced the Indian Evidence Act from 1 July 2024, expressly states that the Act applies to judicial proceedings before a court but not to affidavits presented to a court or officer, nor to proceedings before an arbitrator. Affidavits are governed instead by procedural statutes such as the CPC, BNSS, and the rules the individual court frames.

Who can attest an affidavit in India?

Section 8(1)(e) of the Notaries Act 1952 authorises a notary public to administer an oath to, or take an affidavit from, any person, making a notary the standard attestor outside a pending court proceeding. Courts also authorise their own panels of oath commissioners to attest affidavits filed in that specific court, under rules the High Court frames; which one a given forum expects depends on that forum’s own filing rules.

Does every affidavit need to be notarised?

No. Affidavits filed within a pending court proceeding are frequently attested by an oath commissioner appointed by that court rather than by an outside notary, and some courts accept either. An affidavit made for a purpose outside any pending case, such as an identity or address affidavit, is more commonly notarised. Check the specific forum’s requirement rather than assuming one rule applies everywhere.

What happens if I file an affidavit on plain paper when stamp duty applies?

A registry can return the affidavit for want of the correct stamp, and in some states an unstamped instrument that should have been stamped cannot be acted upon or admitted until the deficiency and any penalty are made good. Because stamp duty on affidavits is fixed by each state’s own schedule, confirm the current requirement for that state and forum before the deponent signs, rather than assuming a fixed national rule.

What is the difference between stating a fact “to my knowledge” and “to my information and belief”?

A fact stated to personal knowledge means the deponent directly perceived it, they were present, or they personally did the act described. A fact stated on information and belief means the deponent learned it from another source and did not perceive it directly. Order XIX Rule 3(1) of the CPC requires that facts on information and belief be confined mainly to interlocutory applications and that the source of that information be disclosed.

What is a jurat, and how is it different from the verification clause?

The verification clause is the deponent’s own certificate about which paragraphs of the affidavit are true to personal knowledge and which are based on information believed to be true. The jurat is the attesting officer’s separate certificate, placed after the deponent’s signature, recording where and when the affidavit was sworn or affirmed and confirming the officer administered the oath in person. Both are required; neither substitutes for the other.

Can an affidavit be amended after it has been signed and attested?

Not by editing the signed document. If a fact stated in a filed affidavit needs correction, the standard route is to file a fresh affidavit, sometimes described as a supplementary or corrective affidavit, that expressly identifies the paragraph being corrected and states the accurate position. Courts generally expect the correction to be transparent about what changed and why, rather than a silently reworded resubmission.

What happens if an affidavit turns out to contain a false statement?

A deponent who swears to a fact known to be false in a sworn affidavit can face prosecution for perjury, and the court can also draw an adverse inference against that party’s case on the point in question. This is the entire reason courts treat affidavits differently from unsworn submissions: the oath is meant to carry a real consequence for a knowing falsehood, not a formality.

Do I need a separate affidavit for every application I file in the same case?

Generally yes. Each application, whether it is an interim application, a reply, or a fresh application raising new facts, is supported by its own affidavit addressing the facts relevant to that specific application, even where the underlying case is the same. Reusing an old affidavit’s facts without swearing to their continued accuracy for the new application is a common defect that draws objection.

What is affidavit evidence under Order XVIII of the CPC?

In civil trials, examination-in-chief, the witness’s own account of the facts supporting their side, is commonly filed as a sworn affidavit in advance rather than delivered orally in open court, while cross-examination on that affidavit is still conducted live before the judge. This practice is meant to save court time on undisputed narration while preserving the opposing party’s right to test the witness under Order XIX Rule 2.

What is the Affidavit of Disclosure of Assets and Liabilities?

It is a standardised financial disclosure affidavit that the Supreme Court’s judgment in Rajnesh v Neha (2020) requires both parties to file in every maintenance proceeding across India, within four weeks of the first hearing, covering income from all sources, movable and immovable assets, and existing liabilities. Courts may draw an adverse inference against a party who files an incomplete or false one.

Can someone else sign an affidavit on my behalf?

Generally no, an affidavit must be sworn by the person whose personal knowledge or belief it records, since the oath and the perjury consequence attach to that individual. Where a party genuinely cannot appear, for example due to illness or being abroad, the usual route is a duly executed power of attorney authorising an agent to swear the affidavit on the party’s behalf regarding facts within that agent’s own knowledge, not a proxy signature on the party’s own statement.

Is an affidavit notarised abroad valid before an Indian court?

Often yes, but subject to the receiving court’s own rules on foreign attestation, which may require attestation before an Indian consular officer, an apostille, or consular legalisation depending on the country and the forum. This is the same practical issue that arises with a power of attorney executed outside India, so confirm the specific court’s requirement before the deponent signs abroad rather than after.

What documents should be annexed to an affidavit?

Any document the affidavit’s text refers to as proof of a stated fact, a contract, a notice, a certificate, a bank statement, should be physically attached and marked as an exhibit, typically Annexure A, B, and onward, with the affidavit’s paragraphs cross-referencing the mark. Describing a document as “annexed” without actually attaching it is a routine and avoidable defect that draws an objection on filing.

Can the deponent of an affidavit be cross-examined on it?

Yes, where the affidavit is being used as evidence. Order XIX Rule 2 of the CPC allows either party to seek the deponent’s attendance for cross-examination on their affidavit, and courts frequently order this in evidence-on-affidavit trials and in disputed interim applications. Where cross-examination is genuinely sought and the witness can be produced, the proviso to Order XIX Rule 1 bars the court from allowing that evidence to be given by affidavit alone in the first place. Drafting an affidavit that will hold up under cross-examination is exactly where a research tool that verifies every cited authority earns its keep; Niyam’s citation checks catch a mismatched or outdated authority before it is sworn to, not after opposing counsel finds it.

What is the difference between an affidavit and a vakalatnama?

A vakalatnama is the document by which a client authorises an advocate to act and appear on their behalf in a specific case; it is not sworn under oath and does not assert facts. An affidavit is a sworn statement of facts, used to support an application, respond to one, or serve as evidence, and always requires attestation before an authorised officer. The two documents serve entirely different functions and are never interchangeable.
