Hello...I was a teenage mother and when my daughter was born I gave her my last name. Since then I have been with my husband for seven years and he has been taking care of her since she was two years old. Now that we are married we want her to have our last name. Her biological father does pay child support, but that is all he does. He has not seen her in over a year. Would this effect the process of changing her name even though she does not have his last name she has my madien name? I do not remember if he signed the birth certificate or not either, would that have something to do with the name change. And can I even get her name hyhentated with her step-father's name.
