Affidavit — in plain language

Plain language

a written statement that someone swears is true in front of a notary or other official who can witness oaths

• sworn written statement
• written oath
• sworn declaration

What to watch for

• Non-lawyers often confuse affidavits with depositions. A deposition is given in court or a lawyer's office under oath; an affidavit is written and signed before a notary.
• Some jurisdictions allow 'declarations under penalty of perjury' instead of affidavits. These are similar but don't require a notary — the translation should clarify whether a notary is involved.
• An affidavit is not proof that the facts are true — it's just a statement that the signer claims is true. The translation should not imply that sworn means verified.
• In contracts, 'lost note affidavits' or 'title affidavits' are specific types with particular legal effects. The plain-language version should explain what kind of affidavit it is.

Why This Term Is Hard to Translate. "Affidavit" sounds formal and intimidating, but the concept is straightforward: someone wrote down facts and swore they're true. The challenge is that non-lawyers may not know what "swearing before a notary" means or how it differs from just signing a regular letter.

What to Watch For.

• Notary requirement: Most affidavits must be signed in front of a notary public. If the document doesn't mention a notary, it might be a different type of sworn statement.
• Specific purposes: In contracts and legal filings, you'll see specialized affidavits like "lost note affidavits" or "title affidavits." These have specific legal meanings that should be explained.
• Penalty of perjury: Some jurisdictions allow declarations under penalty of perjury instead of traditional affidavits. These don't require a notary but still involve swearing the facts are true.

Common Misunderstandings by Non-Lawyers.

• "If it's sworn, it must be true." (No — people can lie under oath. An affidavit is just a statement claiming the facts are true, not proof that they are.)
• "An affidavit is the same as a contract." (No — an affidavit is a statement of facts, not an agreement between parties.)
• "You can write an affidavit yourself and just sign it." (No — it must be witnessed by a notary or authorized official to be legally valid.)

Legal definition

A written statement that someone signs and swears is true in front of a notary public or another official who has the authority to witness oaths. The person signing the affidavit promises that the facts they state are true to the best of their knowledge. Affidavits are used in court cases, loan applications, insurance claims, and many other legal situations where written proof of facts is needed.
