Couples who wish to marry must present proof of identity and personal information to a county clerk, according to Texas Constitution and Statutes. A driver's license, U.S. passport and birth certificate are among the accepted items to establish identity.
In the application, couples must answer statements to establish their eligibility for a marriage certificate, states Texas Constitution and Statutes. The statements include if both people are not married, if they are not related within the same family, and if either person is delinquent with child support.
Both applicants for a marriage certificate must sign an oath that the answers to the statements are truthful, notes Texas Constitution and Statutes. The county clerk confirms the couple signed the oath and adds the date and county of the marriage ceremony and the address where the certificate is mailed.
