 If it does not, the marriage certificate can be used as documentation to justify a legal name change but not as proof that a name change has occurred.If there is no place for a change of name to be recorded, the name is changed as requested on government documents with proof of marriage.In California, under Section 501 of the state's Family Code, a county clerk is authorised to issue a confidential marriage licence and subsequently grant a confidential marriage certificate; Section 511 of the same Code states that the records of marriages registered under this provision are not open to public inspection, except by an order of the court.
