Hi I have a question. I am a step father, and I want to adopt my step daughter. Her mother and I are of course married for seven years. Her bio-father has agreed to sign over his rights. Here is the question, does he sign over his rights to my wife, and then I adopt. Or does he sign over his rights to me and I adopt all in one step? Also he lives in ca and I live in tx, where do I file, here or ca?
