A confidential marriage license is a type of license that is only available to couples who are already living together and do not want their marriage to be a matter of public record. To obtain a confidential marriage license in California, both parties must appear in person at a County Clerk-Recorder's office and provide valid identification, such as a driver's license, passport, or military ID. The couple must also sign a statement indicating that they are living together and not related by blood. After paying the fee, the confidential marriage license will be issued immediately.
