Legal Question in Family Law in California

I think it is realistic for you to get legal and physical custody. I do not generally see judges award 100%, but it is possible for some issues.

If you want help with this please let me know at your earliest convenience.

Mr. Hale is correct. Unless there is some serious issue about the safety of your daughter with her father, chances are almost zero that you will get 100% custody, because that means no visitation. You also cannot change her name if he objects. It sounds like what you are looking to accomplish is a step-parent adoption. That would change the name and cut off your ex's rights entirely. Again, however, unless he consents or disappears entirely for a very long time to where you can't even find him, it's not going to happen. And while I understand your desire to solidify the bonds of your new family, unless your ex is willing to totally turn his back on her, in which case he will consent to the adoption, for your daughter's sake you should probably be fostering an improved relationship with him, not cutting him off.
