a little bit confusing, your father whose last name is what you are using right now is not your biological father, but the court ordered that you retain the names...maybe because during the time that you were born, your mother was still married to him? so how did u become illegitimate? you maybe not hve his blood running through your veins but in the law, he is your father. and how did that become your soon to be father in law's problem? better get a lawyer and sit down and discuss everything and ask him possible outcome or cobsequences
