I am wanting to get my son's last name changed to my husbands last name. His biological father signed over all rights to him legally twice so I didn't know if that would be enough to exclude him from this process. I need to know if I have to get his biological father's permission. Also, my son is 14, does that make a difference in the state of Missouri as I know it does in the state of Michigan?

How did he sign over he rights? A in order for him to have no rights a judge would have to terminate them and that only happens once. I don't think his rights have actually been terminated therefore you would need his permission.

An attorney drew up the papers and we had it done legally but there was no judge involved.

Was there someone to adopt? In absolutely every state I know of a judge has to sign off on it or it isn't final.
