California's new law restricting the release of marriage license information went into effect on January 1. This law is aimed at protecting private information and, as a result, curb identity theft. The law requires people obtaining marriage license information to fill out an application that gives information about the requester. This gives the authorities a record of who asked for the information in case it is later misused.
This is already done regarding birth and death certificates, which have for a decade or more not been available without data about the person seeking the certificate.
I think this law is a good idea and I hope more states follow California's lead.
