Can I stop my sons father from seeing him if he isn't named on the birth certificate and he hasn't seen him for 4 years? I'm so worried. We split 4 years ago after I found out he was cheating and since then he's been living abroad and hasn't seen or spoken to my son since. He's never paid maintenance or had.contact in all that time. Today he showed up at my Mums door asking to see his son.He doesn't know my address as far as I'm aware but I'm terrified he'll show up at my Mums when my son is there and try to take him. Neither of us want to see him. I don't think he has any rights after all this time. Am I right? And does it make any difference that my son doesn't want to see his father either. He's a smart little boy and I have asked him what he thinks and he sees this man as a stranger and although he knows its his dad he has told me he doesn't want to see him. Can I stop him from coming near the house? I'm now with a new partner and 4 weeks away from giving birth. This is putting me under so much stress I could cry. I really need advice but can't afford a lawyer. Will citizens advice be able to advise me. Please help.
