HB 1814 amends provisions in the Family Code to update the forms and procedures related to marriage licenses and declarations of informal marriages. The bill revises the application for a marriage license to allow each applicant to specify their full name, including the surname they intend to adopt after marriage, replacing language that previously focused on the maiden surname of women. It similarly updates the declaration of informal marriage to reflect modern terminology and practices, replacing references to "husband and wife" with "spouses."
