Agree that all access should be recorded in case they take it to court, which they may not do. We have had the old threat of court but it never came to anything. Your DD really needs to get advice on this and not try to struggle on trying to be nice. It doesn't work! Unless she is a family law solicitor she won't know all the complexities. In our case, mediation came to nothing as the father wouldn't engage. But it might be worth trying.
Courts stress that decisions are made in the interests of the child. Note down how often his father had contact with him before the new GF. Also anything he has contributed financially.....which appears to be nothing.
It is very upsetting for you and DD to have these threats to deal with. Even worse is the emotional manipulation of your GS! Appalling behaviour showing total disregard for the little one's wellbeing. You really need to follow up your legal aid status and if possible get a good family law solicitor on the case.
We have been on the receiving end of threats, lies and no financial support. But he has made no attempt to follow through legally, or to see his son. Prefers to tell his sob story to anyone who listens and gives him sympathy. We ignore all of this!
To think that London, or anywhere else for that matter, does not belong to any one demographic
