Legal Question in Family Law in California

Re: Parantage

It's a starting point, but if you want to prove or disprove parentage, you should file a court action to do so.

Re: Parantage

You've listed two states, California and Florida. If the child (therefore your case) is located in Florida, the birth certificate is nearly irrelevant unless you were married to the mother when the child was born. DNA is pretty much the "ultimate answer" to proving parentage in court in Florida. There are some rare exception--like marriage--but the birth certificate is rarely even mentioned in Florida courts.
