First things first: if you're getting married in California, you'll need to get a marriage license. You can do this at any county clerk's office in the state, and they'll also be able to tell you what documents (like your birth certificate) you need to bring with you when you apply for the license. You can have a wedding ceremony at the courthouse, at several branch offices of the Registrar-Recorder/County Clerk, or at an off-site location of your choice. The fee for a marriage ceremony costs $35. For any additional info, check here.
