Affidavit: What It Is, Common Types & How to Make One (2026)

Introduction

An affidavit is a written statement of facts made voluntarily by a person and affirmed or sworn to be true before a person authorized to administer oaths, such as a Notary Public, Oath Commissioner, or another competent authority. Affidavits are widely used in legal proceedings, government applications, banking matters, educational institutions, property transactions, and personal documentation.

Although an affidavit serves as a formal declaration of facts, it does not automatically prove those facts. If disputed, the contents may still need to be established through evidence in accordance with the law.

This guide explains what an affidavit is, its legal purpose, common types, the procedure for preparing one, required documents, and important legal considerations.

What is an Affidavit?

The affidavit is signed by the deponent and is generally sworn or affirmed before a legally authorized official.

Affidavits are commonly used to place facts on record in legal and administrative matters.

How to Make an Affidavit

Step 1: Draft the Affidavit

Prepare the affidavit in clear and simple language.

Include only factual statements that you know to be true.

Step 2: Print the Affidavit

Print the affidavit in the format required by the concerned authority.

In some cases, non-judicial stamp paper of the prescribed value may be required under the applicable State laws.

Step 3: Sign the Affidavit

The deponent should sign the affidavit in the presence of the authorized official.

Do not sign it beforehand if the authority requires signing in their presence.

Step 4: Swear or Affirm the Contents

The deponent must swear or affirm that the statements made are true.

The authorized official will administer the oath or affirmation as required.

Step 5: Get the Affidavit Attested

The affidavit is generally attested by:

• Notary Public.

• Oath Commissioner.

• Executive Magistrate (where applicable).

The competent authority depends on the purpose of the affidavit and the applicable legal requirements.
