Contra Costa County Marriage Services

Contra Costa County offers marriage licenses plus appointment, walk-in, after-hours, window, outdoor, and destination civil ceremony formats from Martinez. A public license is about $95; ceremonies range from about $35 for an expedited window ceremony to about $120 for a destination ceremony, before applicable appointment fees.

Office ceremonies allow up to 15 guests, require one witness age 12 or older, and use a license obtained before the ceremony. The format menu is helpful when a standard weekday chapel slot does not fit.

Pick the ceremony type that matches privacy, guest count, and schedule, then complete the license step before the day-of appointment.
