Marriage forms are legal documents that pertain to the process of getting married. They are used to record and establish the legal union between two individuals. These forms may include application forms, affidavits, marriage licenses, and certificates, among others. They are typically required by government authorities and are filled out by individuals who are planning to get married, as well as by officiants who perform the marriage ceremony. Marriage forms help ensure that the marriage is legally recognized and provide a record of the union.
