A name affidavit is a sworn statement in which you declare that two or more versions of your name — different spellings, a former name, a nickname, a missing middle initial — all refer to the same person. It doesn’t change your name. It explains the inconsistency so a title company, bank, government agency, or court can move forward with a transaction that your mismatched records would otherwise hold up.
How It Differs From a Legal Name Change
A legal name change is a court order that replaces your name with a new one. A name affidavit does something much narrower: it confirms that “Robert J. Smith,” “Bob Smith,” and “Robert James Smith” are the same person. No new name is created, and no court is involved.
If your name actually changed through marriage or divorce, the marriage certificate or divorce decree is usually proof enough on its own. The affidavit becomes useful afterward, when old records under your former name keep surfacing and causing friction. It is also the standard workaround for a name you adopted informally years ago without ever going to court.
When You Actually Need One
Real Estate Closings and Title Searches
This is the most common trigger. A title company examines every deed, mortgage, lien, and court filing tied to a property. If your name appears as “Katherine” on one document and “Katharine” on another, the examiner flags it as a cloud on title, and that cloud can block the closing or prevent title insurance from issuing. A name affidavit — sometimes called an AKA affidavit or a “one and the same” affidavit — clears it by swearing under oath that both names belong to you.
The same thing happens with mortgage underwriting. Credit bureaus often record every spelling variation ever tied to your Social Security number, including misspellings from old creditors. Lenders routinely ask borrowers to sign an AKA affidavit listing every variation and identifying the true legal name.
Passport Applications
The State Department uses Form DS-60 when the name you use now is substantially different from the name on your citizenship evidence and the change wasn’t the product of a marriage or a court order. Two people who know you by both names, preferably blood relatives, each complete the form and swear they have personal knowledge of your use of both. If you can show three or more public documents proving exclusive use of your current name for five years or longer — tax records, employment records, medical records — a single DS-60 from one person may be enough.1U.S. Department of State. Affidavit Regarding a Change of Name – DS-60 A marriage certificate or court order documenting the change eliminates the need for a DS-60 entirely.
Immigration Filings
USCIS expects a government-issued birth certificate as primary proof of identity and birth. When that document is unavailable, was registered late, or lacks key details, the agency may accept affidavits as secondary evidence. Each affidavit must come from someone with personal knowledge of the event and must include the affiant’s full name, address, date and place of birth, relationship to you, and a detailed explanation of how they know what they’re attesting to.2USCIS. USCIS Policy Manual Volume 6 Part J Chapter 3 – Documentation and Evidence An affidavit alone rarely satisfies USCIS; expect to pair it with other records created close to the time of birth, such as baptismal or school records.
Banks, Insurers, and Estates
Banks and investment firms may ask for a name affidavit when the name on an account doesn’t match your current ID, which happens often with accounts still carrying a maiden name. Insurance companies, schools, and licensing boards run into the same problem. Estates are another frequent setting: if a will names “James R. Williams” but the decedent’s property records say “James Williams” with no middle initial, the executor may need an affidavit to connect them.
What to Put in the Affidavit
Unless the institution supplies its own form, you’ll draft one or use a general template. The core pieces are the same either way:
- Your full legal name — the version you consider correct and want records to reflect.
- Every variation that appears on any document involved. List them all, even the ones that look obviously wrong.
- Where each variation appears. For example: “My birth certificate lists my name as Maria T. Garcia; my driver’s license reads Maria Teresa Garcia-Lopez.”
- The reason for the discrepancy — clerical error, marriage, informal adoption, cultural naming conventions, or something else.
- A sworn statement declaring, under penalty of perjury, that the contents are true and correct to the best of your knowledge.
Under federal law, a written declaration signed under penalty of perjury carries the same legal weight as a statement made under oath, even without a notary.3Office of the Law Revision Counsel. United States Code Title 28 – Section 1746 In practice, most institutions that request a name affidavit still want it notarized, and a notarized version is almost never rejected on form.
Attach supporting documents when you can. A marriage certificate explaining a surname change, a birth certificate showing the original name, or a copy of the record that contains the error all strengthen the affidavit and reduce the chance you’ll be asked for more.
Getting It Notarized
Notarization gives the receiving institution independent confirmation that you are who you say you are and signed voluntarily. The notary checks your government-issued photo ID, confirms you understand what you’re signing, and then either witnesses your signature or administers an oath. Name affidavits are usually handled as jurats, because the document contains sworn factual statements rather than a bare signature.4American Society of Notaries. Presence Requirement
You have to appear before the notary; never sign ahead of time and bring in a pre-signed document.5American Society of Notaries. Physical Presence – The Foundation of All Notarial Acts Most states now also permit remote online notarization by live video, which helps when the issue crosses state lines or you’re traveling. Banks often notarize for account holders at no charge; shipping stores, law offices, and mobile notaries are other options. State law caps the fee per notarization, typically from a few dollars up to around $15, with mobile and online services adding convenience charges.
How Long It Stays Good
A properly notarized name affidavit generally doesn’t expire. The notarization is valid as long as the notary’s commission was active when you signed, and the underlying facts about your identity don’t become less true with time. Some institutions impose their own freshness rules anyway. A title company may want one executed within the last 30 or 60 days even though an older one would be legally sufficient. Ask about any time limit before you notarize, so you don’t do it too early.
What a Name Affidavit Won’t Do
The affidavit resolves one transaction. It does not update government databases on its own. The Social Security Administration, for instance, requires an actual legal name-change document — a marriage certificate, divorce decree, certificate of naturalization, or court order — and insists on originals or certified copies from the issuing agency. Notarized copies and photocopies aren’t accepted, and a notarized affidavit about your name history isn’t a substitute for the underlying legal document.6Social Security Administration. Learn What Documents You Will Need to Get a Social Security Card If your records are inconsistent across multiple agencies, plan to update each one separately through its own process.
The Perjury Warning Is Real, But Narrow
Signing an affidavit under oath or under penalty of perjury carries real legal weight; a knowingly false statement can be prosecuted. A declaration made under penalty of perjury carries the same consequences as a statement sworn before an officer.7Legal Information Institute. Declaration Under Penalty of Perjury The DS-60 says so explicitly, warning that false statements are punishable by fine or imprisonment under the general perjury statute and under laws specific to passport fraud.1U.S. Department of State. Affidavit Regarding a Change of Name – DS-60
Be thorough and honest, and the warning takes care of itself. The perjury risk exists for people using affidavits to claim someone else’s identity or assets, not for someone cleaning up a misspelled middle name on a decades-old birth certificate.
