I do apologize for my delay. As soon as I sat down to reply, I got very busy and the phone started ringing.
In answer to your question - well, I'll be darned -yes, you can do this. Section 306.5 pecifies that a person may adopt any of the following last names:
the current last name of the other spouse
the last name of either spouse given at birth
a name combining into a single last name all or a segment of the current last name or the last name of either spouse given at birth
a hyphenated combination of last names.
Thus, since your last name is ***** ***** or both of you could change your name to say, A (First name) B (Last Name) or A (First Name) C (Last Name).
California Family Code section 306.5(b)(4) provides that such election by a person to change his or her name serves as a record of the name change. A certified copy of a marriage certificate containing the new name, or retaining the former name, shall constitute proof that the use of the new name or retention of the former name is lawful.
So, you would still have to go to the DMV
and social security to update them with the change of name of course, but your proof of lawful name change, if requested, is a certified copy of the marriage certificate.
