My question involves name change laws in the State of: California
The person listed on the birth certificate is not the bio-logical father. I want to prove this in court because he threatend to TAKE my 2 year old daughter. She currently has his last name big mistake, Me being too nice. Once the DNA proves he is NOT the father, do I still need his permission to change her name and can I then remove him from the birth certificate and be done with this mistake once and for all.
