MY STBXH and I separated over a year ago. He moved to a new house near his work and we agreed that he could have DS aged 2.5 at the time every weekend and could take him for holidays. We mostly did the handovers halfway between us on neutral ground but sometimes we would go to each other's houses and I would often cook family meals at mine as think that's important for DS. Ex had keys to marital home that DS and I are still in but I asked him not to use them and not to try gain access if I was not in. He admitted that when we were away last summer he did enter the house and he removed paperwork to do with the divorce. So I changed the locks but didn't tell him. This summer he tried to gain access again when we were away and found he couldn't. He moved to a new house even further away 3 months ago and will not let me in it. First he said he need to get it sorted and cleaned and needed 2 days to do that. I gave him the time and now he says that he just point blank will not let me in as I won't let him into out house (I do just only when when I am there and that's all I want from him). I just want to see where DS will be sleeping as I don't think EX has got him a proper bed and at nearly 4 yrs old he should have one. Also I really miss Ds at weekends and it would help to be able to picture where he is. I am happy just to visit once to see the set-up. AIBU to want this? Does anyone know if legally I am on strong ground or not? I am not happy for DS to spend time there now until I have seen the set-up as I wonder what EX has got to hide. Overall I just want to put my mind at rest that EX can provide a appropriate, clean safe environment (I still remember the state of his house before we got together!). Can anyone advise please?
