Affidavit of Marriage

When to use Affidavit of Marriage

An affidavit of marriage serves as a written statement made under oath made in regards to the date, validity and occasion of your marriage. This kind of sworn declaration may be used for many legal purposes. Affidavits of marriage are often used as evidence during family legal contests (such as divorce and child support cases) but they may also be used in order to confirm facts for the purposes of updating a passport, securing a joint line of credit, etc.

After you have filled out an affidavit of marriage, you will need to ensure that it is properly notarized. This process allows interested parties to treat the marriage-related information you have produced as a sworn statement for any relevant purpose. As an affidavit is a sworn statement, it is important to be accurate when completing it, as providing inaccurate or incomplete information could lead to undesirable legal consequences.


At any time that you need to make a statement under oath (as legally defined) about your marriage (including where and when you were wed), you may be able to use an affidavit of marriage in order to do so. Similarly, if you cannot obtain a complete and accurate marriage certificate, an affidavit of birth may serve as an adequate substitute under certain circumstances.

Please contact a family law attorney if you have any questions about ensuring that your marriage affidavit has been properly drafted, notarized and submitted. If you need to make a sworn statement about your marriage, filling out this document can help you to accomplish that goal.
