Start a Fort Bend Marriage License Online, Then Sign With the Clerk
Whether you live in Sugar Land, Katy, or an unincorporated stretch out toward Needville, a Fort Bend wedding starts at one place: the County Clerk in Richmond. You fill out the marriage-license application online first, then both people walk into a county office to sign it in front of clerk staff. That same office is where couples file a declaration of informal (common-law) marriage.
Once the license is in hand, Texas makes you wait 72 hours before the ceremony, with a handful of exceptions. The harder cases have their own paths: an applicant who can't be there in person, or a couple asking to waive that waiting period. Reading the ID list and pulling the right form for your situation before the trip is what keeps a quick errand from turning into two.
Almost everything that goes sideways here is paperwork, not law. Show up with valid ID and the application already done and you're in and out; arrive a document short and you're driving back. The license itself is the easy part — it's the missing item that costs you the day.
