The marriage license and the certified copy are two different errands

The Starr County Clerk keeps the marriage counter in the courthouse at 401 N. Britton Avenue in Rio Grande City. The county page links its license rules, an absent-applicant form, and a separate form for an informal marriage. Texas usually puts 72 hours between the license and the ceremony. The law has exceptions, and a judge can waive the wait in some cases. Do not plan on a same-day license unless the clerk confirms that one of those paths fits.

The license lets the marriage happen. It is not the certified copy people later use for records and name changes. That copy is a second request after the completed license comes back to the clerk for filing.
