My DH has never known his biological father as he left his Mum when DH was a baby. His Mum remarried and DH was not adopted as his birth father wouldn't agree to it but his surname was changed by deedpoll. We know his name as it is on the birth certificate but we do not know anymore information as DH's Mum will not discuss the situation (the only time it was mentioned was when they told him when he was 14 that his Dad wasn't his biological Dad and it has never been talked about since and he is now 31!!)
DH is considering looking into tracing his father but we don't know where to start so any advice would be appreciated.
TIA
