Each state requires a marriage license to legalize a marriage and state marriage laws vary. Obtaining a wedding license is the responsibility of the bride and groom. Usually, both parties about to marry need to sign the marriage application in person. You cannot get legally married without a valid Marriage License. Following the wedding ceremony, both spouses and the Wedding Officiant sign the marriage license and some states require the signature of a witness. Marriage license witnesses must be 18 years old. The Officiant then files for a certified copy of the marriage license, which is usually called the marriage certificate. You should make sure to purchase a certified copy of your marriage certificate if it is NOT included in the license fee as this is legal proof of marriage and name change. You must always have a marriage license or wedding certificate from the state in which the marriage ceremony will be performed.
