You Can’t Get Married Without a Marriage License!
Before you say “I do,” you’ll need a valid marriage license—it’s the one legal requirement for your wedding. In fact, all that’s truly needed for a legal marriage is a signed marriage license and a simple “I do.”

Residency & Citizenship Requirements
✔ Marriage license applicants do not need to be Washington State residents.
✔ A marriage license obtained in any Washington county is valid statewide.
✔ Applicants do not need to apply for a license in the county where the wedding will take place—any county-issued license is valid across the state.
✔ A Washington State marriage license cannot be used in another state or country.
