I became pregnant and the man who signed the birth certificate is not the father. At the time, I thought he was the father and did not find out he was not until a little later. I want to change the name of the father on the birth certificate to the real father and to change the child's name as well. Both men have agreed to this change and will not dispute it. Both men have agreed to sign any documents needed to be signed. I don't know where to start with this process because my son was born in Mississippi and now I live in Tennessee. Any advice will be much appreciated.
