i would like to know what i need to do to be able to change my step-daughter's name to my last name, but there are a couple other issues i may have to deal with first. for one, her maternal grandmother has legal custody of her but she is residing with myself and my wife (her mom). her mom has no problems legally to be able to regain custody of her. she thinks i need to adopt her to be able to change her name. the biological father is currently incarcerated for sexually molesting 3 of my wifes other daughters. she was told that because of this he lost his rights to his daughter. do we need his permission? please someone help me to figure out what to do.
