Basically we are thinking about going to court for full custody as social services are not doing anything to help even though they have said ss is at risk of emotional and physical abuse bm and partner have failed parenting assessments and he isn't allowed around ss at all not even over the phone contact. She leaves ss with us while she goes to the contact centre with him to see his son and always wants us to have him extra days so she can with him. We found out they are viewing houses to move into together so we want custody of ss ( even though everyone knows this) for his safety now, he's also on child protection register and we have a whole ss case of concerns with her .What are the chances of us having full custody as we will have to pay for court and solicitors.
