Will do my best to brief, but it's complicated, sorry.
DP has 2 DS (DS 1 & 2) that live with us and another 2 DC (DS 3 &4) that live with their mother (not same woman)
Recent problems with DP's parents have meant that they are not allowed unsupervised access to DS 1&2. This is not our decision, but that of SS. We support it though.
When DP's parents were told this, they caused a lot of problems and went to a solicitor to demand unsupervised access. We went through our solicitor and refused this, but offered for them to visit DS 1 & 2 at our home every week.
At the same time, mother of DS 3 & 4 suddenly says DP can't see them, no valid reason given. A letter then arrives from her solicitor to say that he is only allowed supervised access to DS 3 & 4 for 2 hours per week. Supervised by their mother.
Odd thing is, they both have the same solicitor - even the same partner in the firm! We suspected they were all working together, as mother of DS 3 & 4 is determined to cause trouble, but this seems loony. Can they do this? Posted in AIBU for traffic too.
