You can sign your name as it appears on your identification or you can sign with your spouse's name that you are taking on the bride and groom lines of the certificate.
Self-solemnizing couples, who perform their self-solemnization in the Clerk and Recorder Office, should sign their current name on the certificate on the official title line as well as, bride and groom lines. You also have the option to sign on the bride line and groom line in your spouse's last name, if you choose to. It is not a requirement to do so.
Please note: Name changes are not made by the Clerk and Recorder Office. You are responsible for making name changes through Social Security, motor vehicle, etc.
