Affidavit Of Relationship Template for the United States

An Affidavit of Relationship is a sworn statement in which one person confirms, in writing and under oath, that a relationship exists between two people. It reads much like a formal letter of proof: you set out who you are, who the other person is, and how you know the facts you are describing. Authorities ask for it when they need reliable evidence of a family, personal, or friendship connection, and it carries weight because you sign it under penalty of perjury.

What is an affidavit of relationship?

It is a signed, notarized document that puts a relationship on the record. The person making the statement is called the affiant. Common examples include a spouse confirming a marriage, a parent confirming a child, a partner confirming a domestic relationship, or a friend confirming that they know a couple or an individual well. In that last case people often ask for a supporting letter from a friend, and an affidavit is the sworn version of that letter. A relationship affidavit is sometimes filed alongside an affidavit of support, where one party takes financial responsibility for another, so it helps to know which document each agency actually needs.

When do you need this document?

You'll need an Affidavit of Relationship in various legal and administrative situations. Immigration proceedings frequently require these affidavits to prove family relationships for visa applications, green card petitions, or naturalization cases. Insurance companies may request them to add beneficiaries or dependents to policies. Legal proceedings, including probate cases, custody disputes, or inheritance matters, often require sworn testimony about family relationships. Government benefit applications for social security, veterans' benefits, or healthcare programs may also require formal relationship documentation. Additionally, you might need this document for name changes, adoption proceedings, or when establishing guardianship rights.

What should an affidavit of relationship include?

To be accepted, the document should set out each of the following clearly:

• The affiant's details: full legal name, home address, and other identifying information for the person signing.
• The other person's details: the full name and identifying information of the person the affidavit is about.
• The nature of the relationship: the specific type of relationship (spouse, relative, partner, friend) and how long you have known the person.
• Supporting facts: concrete details that show how you know what you are attesting to, drawn from your own knowledge rather than assumption. Where a relationship rests on a documented event, a birth certificate or marriage certificate can back up the statement.
• The verification statement: a line confirming the information is true and correct under penalty of perjury.
• Signature and notarization: your signature, the date, and, where the state requires it, a notary public's acknowledgment with the notary stamp and signature.

Do you need a notary?

It depends on the state and on who will read the affidavit. Some states and agencies accept an unsworn declaration signed under penalty of perjury per 28 U.S.C. 1746. Others require the affiant to sign in front of a notary public, who then adds a notary stamp and signature to confirm your identity and that you signed willingly. Because the requirement differs, check what the agency receiving the document asks for before you sign. When notarization is required, do not sign the affidavit until you are in front of the notary.

Key legal considerations

Your affidavit must include specific elements to be legally valid and admissible. The document requires your full legal name, home address, and identifying information as the affiant. You must clearly describe the nature of the relationship, including how long you've known the person, the specific type of relationship, and detailed facts supporting your knowledge. The verification statement confirms that all information is true and correct under penalty of perjury. Remember that providing false information in a sworn affidavit constitutes perjury, a serious criminal offense that can result in fines and imprisonment. Include only facts within your personal knowledge, and avoid speculation or hearsay. Supporting documentation such as a birth certificate, while not always required, can strengthen your affidavit's credibility.

Legal requirements in the United States

Federal law governs affidavits through 28 U.S.C. 1746, which allows unsworn declarations under penalty of perjury in federal matters. For immigration purposes, the Immigration and Nationality Act sets specific requirements for relationship documentation. State laws vary significantly regarding notarization, with some states requiring a notarial acknowledgment while others accept unsworn declarations. You must execute the affidavit in compliance with the laws of the state where you sign it. Most states require the affiant to be at least 18 years old and of sound mind. The Federal Rules of Evidence determine admissibility in federal court, while state evidence rules apply in state courts. Make sure your affidavit meets the specific formatting and content requirements of the jurisdiction where you'll use it, as non-compliance can result in rejection.

Common questions about affidavits of relationship

Two questions come up often. First, can a friend write one? Yes. A friend with direct, personal knowledge can serve as the affiant, which is common in immigration cases where a friend confirms that a relationship is genuine. Second, how is it different from a support letter? A support letter is an informal account, while an affidavit is the same information sworn under penalty of perjury and, where required, notarized, so agencies treat it as stronger evidence. If you're unsure which document fits your situation, start from the template above and adjust the facts to match your relationship and the agency you're filing with.
