An affidavit is sworn before a notary under penalty of perjury. If the request simply asks you to prove your address, a signed proof of residency letter is usually enough — draft one with the generator, then have it notarized only if an affidavit is specifically required.
An affidavit of residence is a written statement, sworn under oath before a notary public, that confirms where a person legally lives. The word "affidavit" is what sets it apart from an ordinary proof of residency letter: the person signing — the affiant — swears that the facts are true under penalty of perjury, and a notary certifies that oath. That sworn element is exactly what a requester is after when they ask for an affidavit rather than just a letter.
Because it carries the weight of a legal oath, an affidavit of residence is used where a plain confirmation would not be trusted: enrolling a child in a specific school district, registering a vehicle, proving in-state residency for tuition, or establishing residence in a court or government matter. The affiant can be the resident themselves or a third party with direct knowledge, such as a parent, landlord, or relative.
Sworn under oath and notarized. The affiant signs in front of a notary, who completes a notarial certificate. Required when an official body wants a legally binding statement — a school district, the DMV, a court, or a securities transfer agent.
A signed confirmation of address, often written by a landlord, employer, or family member. No oath, and usually no notary. Accepted by most landlords, banks, and everyday requests — and far faster when nobody specifically asked for an affidavit.
Read the request carefully. If it says "affidavit," plan on notarization. If it just asks you to prove where you live, use the generator to create a proof of residency letter and skip the extra step. Our proof of residency letter sample shows what the letter version looks like.
A valid affidavit of residence generally states:
Some requesters, especially school districts, also ask you to attach supporting documents such as a utility bill or lease in the resident's name. See what counts as proof of residency for the documents commonly accepted alongside the affidavit.
The first four concern a living person's current address. The last, the affidavit of domicile, is a distinct legal document about a decedent's state of residence — check which one your requester actually means before you prepare it.
Draft the statement — your name, the address, how you know it, and the sworn language.
Take it to a notary and sign in their presence so they can administer the oath.
Submit the notarized affidavit, with any supporting documents the requester asked for.
Do not sign an affidavit before you reach the notary — the whole point is that the signature is witnessed under oath. Notarization is available at most banks, shipping stores, and law offices, and online notaries are accepted in many states. If a court or agency handed you their own blank affidavit as a PDF, you can type the details into the affidavit form online first, then print the completed document to sign at the notary.
When no one specifically asked for a sworn affidavit, a signed proof of residency letter is accepted almost everywhere and takes minutes. Generate one, then have it notarized only if an affidavit is required.
