I have filed papers to change my 17 yr old son's last name to my husband's, who has raised him since he was a baby. They tell me by law I have to serve the biological father. HUGE PROBLEM. I have no idea where he is. I have not seen him in 17 years. I have looked for him at his last known address with no luck. Does anyone have any ideas what should be done next? I have to show proof of service on my court date April 2nd.
