Affidavit of Birth

An Affidavit of Birth is a sworn statement used to establish a person's date and place of birth when an official birth certificate is unavailable, and it is legally valid once signed before a notary public and based on the affiant's personal knowledge. Government agencies, including the Social Security Administration, state DMVs, and U.S. passport offices, accept Affidavits of Birth as secondary evidence under their own documentation rules, often requiring statements from two people who have known the individual since early childhood. The affidavit derives its legal force from the oath: the affiant swears under penalty of perjury (28 U.S.C. 1746) that the birth facts are true. Because it is secondary evidence, an Affidavit of Birth rarely outranks a delayed or amended birth certificate when one can be obtained, but it bridges the gap for older individuals, foreign-born applicants, and those whose original records were lost or never filed.

An Affidavit of Birth should be signed by someone with direct, personal knowledge of the subject's birth, such as a parent, an attending physician or midwife, an older relative, or a long-time family friend present at or near the time of birth. Most agencies that accept these affidavits, including the Social Security Administration and U.S. Department of State for passport applications, prefer two affiants who are not the applicant and who have known the person since infancy. The affiant must be an adult competent to swear an oath and must base the statement on what they personally witnessed or know, not on hearsay. Each affiant signs before a notary public, who verifies identity and administers the oath. When the only people with firsthand knowledge are deceased, applicants typically must rely on a delayed birth certificate procedure through the state vital records office instead.

An Affidavit of Birth is needed when a person must prove their date or place of birth but cannot produce an official birth certificate, a situation common for individuals born at home, born before universal birth registration, or born abroad without consular records. Typical triggers include applying for a Social Security card, obtaining a REAL ID-compliant driver's license, securing a U.S. passport, enrolling in school, or claiming benefits where age must be documented. Each requesting agency sets its own evidentiary standard, so an applicant should confirm whether one or two affidavits are required and whether additional secondary evidence, such as a census record or baptismal certificate, must accompany them. The affidavit supplements rather than replaces the official record, so applicants should also pursue a delayed birth certificate from the state vital records office when eligible.

An Affidavit of Birth must be notarized to be accepted by most government agencies, because notarization is how the affiant's sworn oath is formally administered and authenticated. The notary public verifies the affiant's identity with valid photo identification, witnesses the signature, confirms the affiant swore the contents are true, and then completes a jurat with a seal. Without notarization, the document is an unsworn statement and the Social Security Administration, DMV, and passport offices will generally reject it. Some agencies accept a federal unsworn declaration under 28 U.S.C. 1746 in place of notarization, but for birth-evidence purposes the safer practice is full notarization for each affiant. Because requirements differ by agency and state, applicants should confirm the exact format, including how many witnesses must sign and whether the agency provides its own affidavit form.

An Affidavit of Birth should include the full legal name of the person whose birth is being attested, their date and place of birth, and the names of the parents, along with the affiant's full name, address, relationship to the subject, and the basis of their personal knowledge. The statement must explain how the affiant knows the birth facts, for example by being present at the birth or by being a close relative who has known the person since infancy. Accuracy is essential because the affidavit is sworn under penalty of perjury under 28 U.S.C. 1746, and false statements can result in criminal charges and denial of the benefit sought. Each affiant signs and dates the document before a notary public. Agencies frequently require two separate affidavits from different witnesses, so applicants should prepare and notarize each one independently to satisfy the documentation standard.
