Both parties should visit any county clerk's office in California. In the San Fernando Valley you would go to the Van Nuys Court House. In Ventura County it would be the Ventura Court House or the County Recorder's office in the Thousand Oaks Civic Center. In other parts of California, you will need to check online for the most convenient office to your location. Find out when their hours are, how much your license will cost, and what forms of identification and/or other documents will be needed. Fees can be paid by cash or personal check only. When your ceremony has been performed and after the marriage license has been signed by the bride, groom and witnesses, I will mail your license to the County Clerk's office based on the county you were married in to be filed. You are responsible for obtaining registered copies. You can be married the same day or any day after your license is issued before the license expires. The license expires 90 days from date of issuance.
