What is an Affidavit?

Affidavits are used in many personal and professional situations, yet most people only encounter them when asked to provide one.

If you’ve never prepared an affidavit before, the idea of signing a statement under oath can be unclear.  Understanding how affidavits work helps you avoid mistakes and make sure yours is accepted during any legal proceedings.

This guide explains what you need to know about affidavits for personal, business or legal reasons.

What is an affidavit?

An affidavit is a written statement of facts confirmed as true by the person signing it. The signer takes an oath that the information is accurate. Affidavits are used in legal, financial, government, and construction workflows where verified statements are required for documentation or approvals.

Affidavits are typically witnessed or signed before a notary public. They are considered legally binding and helps provide proof during various legal proceedings and court cases. Many organizations now support digital affidavits and secure e-signing where local regulations allow.

Why are affidavits used?

Affidavits are used any time a person or organization needs a verified written statement of facts. They help document events, confirm information, support legal proceedings or administrative processes, and provide a written record that can be trusted because the signer is making the statement under oath.

They’re often used to:

• Confirm deliveries or completed work
• Record incidents or losses
• Verify identity or ownership
• Support compliance and permitting  
• Document project milestones

Affidavits provide a simple, yet credible way to ensure different parties rely on the same facts.

How does an affidavit work?

An affidavit works by having a person write a sworn statement of facts, then sign it under oath in front of a notary or authorized official or witness. The signer confirms the information is true, and the final document becomes admissible as a legally recognized record.

Organizations use affidavits because they provide prove reliable, verified information in legal matters, financial reviews, or administrative tasks. An affidavit has the following key components:

• Statement of the facts
  Clear facts are required. They must be complete, accurate, and free from coercion.
• Oath or affirmation
  The signer must take an oath voluntarily and must fully understand the contents before taking the oath.
• Signature of the person making the statement
  A valid affidavit includes the signature of the person making the statement (the affiant).
• Signature of a witness or notary (when required)
  Most affidavits must be witnessed or notarized. A notary public or witness verifies identity, confirms the oath, and signs or stamps the affidavit to make it valid.

Giving false information in an affidavit can result in penalties, including perjury, fines, or jail time.
