We separated 6 weeks ago. He moved out to his Mum's. I allowed v generous access - he comes 4 evenings a week for an hour and half - and then is here 12-6 on sunday - whilst I make myself scarce. Kids can't go to MILs (alcoholic). We have not done anything legally yet - but he is constantly pushing the boundaries on what we agreed. This morning I popped out with younger child and returned to him in the kitchen whipping up pancakes for the older children (teens). We own the house jointly. Do I just have to tolerate this until the house is sold? Or can I instigate/enforce some sort of official access schedule? No idea where to start, how long it would take and how much it would cost.
