My question involves name change laws in the State of: California
County: Contra Costa
I have two daughters. They have my maiden last name as theirs. Biological father is not listed on birth certificates. His location is unknown but probably still resides somewhere is Calif. He has not been around or involved for 8+ years.
I would like to legally change my daughters' last name from my maiden name to my married name.
Is this possible to do without the other parent??
Thank you.
