One of the first things my ex did was to threaten me with a non-mol & occupation order. My solicitor told me to ignore it as it would take ages to get to court and probably wouldn’t succeed anyway.
It has been touch and go on whether or not to serve him with one as his behaviour has been horrible and he refused to move and refused to help with the house in any way at all. I decided ultimately that it wasn’t worth it. If it failed, it would have been hugely expensive and it would have made him feel even angrier and more entitled.
He has finally moved out. Hooray!
