Marriage Affidavit Template for the United States

A Marriage Affidavit is a sworn legal document that establishes your eligibility to marry under United States federal and state law. This notarized statement provides official verification of your marital status, age compliance, and legal capacity to enter into marriage. The document serves as crucial evidence for immigration proceedings, international marriage applications, and state marriage license requirements across all U.S. jurisdictions.

What is a marriage affidavit?

A marriage affidavit is a written statement, signed under oath before a notary, that confirms facts about a person's ability to marry or about an existing marriage. It is sometimes called an affidavit of marriage, an affidavit for marriage, or an affidavit of eligibility to marry, and the same template covers each use. People reach for one when a marriage certificate cannot be produced, when a foreign authority needs proof of single status, or when a marriage-based application needs third-party or first-person verification of a genuine relationship. It supports a marriage certificate as evidence; it does not replace the certificate itself.

When do you need this document?

You need a Marriage Affidavit when applying for marriage-based immigration benefits through USCIS, as the Immigration and Nationality Act requires proof of valid marriage eligibility. International marriages often require this document to satisfy foreign consular requirements and establish single status abroad. State marriage license offices may request affidavits when standard documentation is unavailable or when verifying compliance with waiting period laws. Military personnel stationed overseas frequently need these affidavits to marry in foreign jurisdictions while maintaining U.S. legal compliance.

How do you create and sign a marriage affidavit?

Start from a marriage affidavit template, fill in the full legal names, addresses, dates of birth, and citizenship status of both parties, then set out the sworn facts you are confirming. Sign the affidavit in front of a notary public, who verifies your identity and administers the oath before adding their seal. For overseas use you may also need an apostille to certify the notarization. You can browse related sworn statements in the affidavit templates library.

What information do you need before you start?

Gather the details for both spouses before you begin so you can complete the affidavit in one sitting:

• Full legal names and any former names for each spouse
• Current home addresses and dates of birth
• Citizenship or immigration status of each party
• Date and place of the marriage, if one has already taken place
• Details of any prior marriages and how each ended
• The name of the consulate, agency, or license office that requested the affidavit

If you need to change any facts later, update the affidavit and have it notarized again, since a signed sworn statement cannot be edited after the fact.

Key legal considerations

Your affidavit must include complete personal information for both parties, including full legal names, addresses, dates of birth, and citizenship status. The declaration of eligibility section requires sworn statements about mental capacity, age requirements, and absence of prohibited relationships under state law. Any previous marriages must be fully disclosed with dates, locations, and dissolution details to satisfy full faith and credit requirements between states. The legal compliance statement must affirm adherence to all applicable state marriage laws, including minimum age requirements and any mandatory waiting periods. False statements in a marriage affidavit constitute perjury and can result in federal criminal charges, immigration consequences, and invalidation of subsequent marriage proceedings.

How does a marriage affidavit differ from a marriage certificate?

A marriage certificate is the official record issued by a vital statistics office proving a marriage took place. A marriage affidavit is your own sworn declaration of facts, used to fill gaps the certificate cannot, such as confirming single status before a wedding or explaining a missing record. The table below sets out the difference.

Legal requirements in United States

Federal law under the Defense of Marriage Act and Obergefell v. Hodges guarantees equal marriage rights regardless of gender, requiring your affidavit to comply with constitutional equal protection standards. State age requirements vary significantly, with most states requiring parties to be 18 or older, though some allow marriage at 16 or 17 with parental or judicial consent. Waiting period laws differ by state, with some requiring mandatory delays between license application and ceremony, which must be acknowledged in your affidavit. The document requires notarization by a licensed notary public and may need additional certification for international use through apostille procedures. Immigration applications require specific language confirming the marriage's validity under both state law where performed and federal immigration statutes.

Who uses a marriage affidavit?

Individuals and couples use it for personal immigration and international marriage needs, and organizations sometimes need one to verify an employee's marital status for benefits or relocation. Businesses in relocation, real estate, and cross-border hiring may ask for a marriage affidavit as supporting evidence when a certificate is delayed. If you have a question about which facts to include or need to match the wording to a specific consulate or state office, start from the template and adapt the sworn statements to match the request.

Where to find help

A marriage affidavit is not a contract or a financial agreement between spouses, so it does not settle property or support terms. If you need those, a separate document such as a prenuptial or postnuptial agreement covers them. To find and prepare the right sworn statement for your situation, select the marriage affidavit template, complete both parties' details, and adapt the eligibility language to the office that asked for it.
