Name Change

Can I change my son's last name from his biological dad's to mine without his consent in Oklahoma? We were never married and he is not on the birth certificate.

Okay so I was adopted when I was eight and my adoptive parents changed my name is there anyway I could change my name back to my birth name. Also I am trying to find my younger brother how do I go about doing that?

My son has his bio dads last name. He really wants Our entire families last name hyphenated with his current last name. how do I go about doing this in Iowa? I’m married and have other children with my current husband. our names all match. My son doesn't feel like a part of us.

My 13 year old daughter has known another man as her father since she was 12 months old. She met her biological father in 2016 for the first time he was died in a car accident a few months later. She has always had her biological fathers last name but has been asking to change her last name way before she met her biological father. She continues to ask and both I and her father agree along with her to have her last name changed. Can this be done and if so how do we get started?

My husband was adopted by his stepfather when he was very young. He went to live with his biological father as a teenager. His biological father told him that he had his name changed back to his original birthname.My husband has been going by his biological last name for over 35 years. He applied for his birth certificate to get his passport and found out his biological father never changed his last name back to his biological last name. What do we need to do now to get this straight and so he is legal to use jis original biological last name? He has been filing taxes,has sscard and drivers license in his biological last name. We have a mess.I have contacted the Horry County courthouse where the adoption took place and they have no records of the adoption but his birth certificate in VA has his adopted name.
