Summary

An affiant is the person who makes and swears an affidavit, confirming that all statements written in it are true to the best of their knowledge. The affiant signs the affidavit in front of a notary public or oath commissioner, making it a legally valid sworn statement. Affiants are commonly involved in legal, identity, and official processes such as court matters, passport verification, address or name change, and employment documentation. Providing false information in an affidavit can lead to legal penalties or perjury charges.

Are you confused about what is an affiant and how this role evolved in courts? An affiant is a person who swears to the facts in an affidavit, which is used as legal evidence. In India, affidavits were standardized during the colonial administration and are now governed by the Oaths Act, 1969. An affidavit must state facts truthfully, be drafted clearly, and remain accountable. Knowing the affiant's meaning helps in property transactions, banking, and official filings. The process saves time, and the cost usually ranges from ₹50 to ₹100.

What is an Affiant?

An affiant is a person who voluntarily swears a written statement, called an affidavit, before an authorized authority, declaring facts as true. The affiant takes legal responsibility for accuracy, honesty, and completeness. This sworn declaration is widely used in courts, banking, property matters, and government procedures across India legally. This definition of "affiant" is best understood with the real-life situations that are mentioned below:

  • Court Affidavit: A witness affiant submits an affidavit to support a civil suit, sworn before an oath commissioner or magistrate under the Oath Act 1969.
  • Government Application: An affiant signs an affidavit declaring the correct date of birth for a passport or name correction, sworn in front of a notary/authorized officer.

Who Can Be an Affiant?

To understand who can be an affiant, it is important to know the legal requirements for this role. An affiant must be a person who is legally competent to make a sworn statement. This generally means the individual must be of the age of majority (18 years or older) and of sound mind, capable of understanding the contents of the affidavit and the legal consequences of signing it. [1][3]

Duties and Responsibilities of an Affiant

An affiant has several crucial duties and responsibilities that underscore the seriousness of their role in the legal process.

  • To State the Truth: The foremost duty is to ensure that all statements made in the affidavit are true and accurate to the best of their personal knowledge.
  • To swear an Oath: The affiant must formally swear an oath or make an affirmation before an authorised official like a Notary Public that the contents of the affidavit are true. [2]
  • To Understand the Content: It is the affiant's responsibility to read and understand the entire affidavit before signing, as its contents legally bind them. [1]
  • To Disclose the Source of Information: If any statement is not based on the affiant's direct knowledge but on information received from another source, the affiant must disclose that source in the affidavit.  [3]

Rights and Liabilities of an Affiant

An affiant has specific legal rights and responsibilities when giving a sworn affidavit, and understanding them helps you avoid mistakes and confidently handle court or official processes in India. 

  • An affiant can correct genuine errors through proper procedure, but deliberate misstatements create criminal liability and weaken credibility permanently legally. [1][3]
  • An affiant has a right to state facts voluntarily but is liable for truthfulness, facing penalties if statements are false.
  • An affiant may seek legal guidance before swearing, yet remain personally responsible for accuracy, clarity, and consequences under law.

Common Documents Where an Affiant is Required

The role of an affiant is central to many common legal and administrative documents that require a sworn declaration of facts, and professional affidavit services assist in preparing, verifying, and notarizing these declarations to ensure their legal validity. [3]

  • Affidavits for Name Change: The person changing their name is the affiant.
  • Education Gap Affidavits: The student explaining their academic break is the affiant.
  • Proof of Income Affidavits: The individual declaring their income is the affiant.
  • Power of Attorney Documents: The person granting the power (the principal) often signs an affidavit as the affiant.
  • Applications for Passports and Visas: Certain declarations within these applications are made as an affiant.
  • Court Petitions and Filings: Many documents submitted to a court require a supporting affidavit from the petitioner, who acts as the affiant.

Difference Between Affiant, Deponent, and Witness

Understanding legal roles avoids confusion, especially when affidavits are involved; knowing the affiant's meaning helps clearly differentiate between an affiant, deponent, and witness in courts and official proceedings. [1][2]

Legal Documents Requiring an Affiant

An affiant is required for any legal document that needs to be presented as a sworn statement of facts. These documents are used when a formal, personal declaration is necessary. [3]

The most common legal documents that require an individual to act as an affiant in an affidavit are:

  • Affidavits for various purposes (e.g., change of name, proof of address/income).
  • Applications for government-issued documents like passports.
  • Certain declarations filed in court as part of a legal case.
  • Loan applications where a self-declaration of certain facts is needed.

Examples of When You Need to Be an Affiant

You may need to act as an affiant in many common life situations. These examples illustrate when you would need to prepare and sign an affidavit. [1][3]

  • When you have lost your original educational certificates and need to apply for duplicates.
  • When you are applying for a marriage certificate, you need to declare your age and marital status.
  • When you legally change your name, you need to declare your old and new names.
  • When a student takes a gap year, they need to provide a formal reason to a university.

Mistakes to Avoid When Acting as an Affiant 

Acting as an affiant is a serious legal responsibility, and avoiding common mistakes helps you stay safe, credible, and legally compliant when submitting affidavits for courts or official government purposes. Below are a few mistakes to avoid as an acting affiant:

  • Making false or exaggerated statements, which can lead to penalties under the Oaths Act, 1969, and damage your legal credibility.
  • Submitting unsigned affidavits, as missing signatures make the document invalid and unacceptable in courts or government offices.
  • Using incorrect notarization, such as signing before an unauthorized person, which can result in rejection of the affidavit entirely.
