I'll try to keep this brief but it may not be. I separated from my H two years ago and he moved out. He was and has continued to be abusive in a number ways, not paying any maintenance, refusing to agree to any childcare agreements -- grudgingly does two school pick-ups a week and then disappears. My daughter lives with me all the time. He constantly demands money from me. He's got fairly severe mental health problems and his life has unwound over the past few months to the point where he has difficulty working and he's about to be kicked out of the flat he's rented for two years.
I've offered to help him with a deposit towards a new flat and he says no and is demanding to move back in to my flat until the divorce goes through (I am going to have to pay out to him, he doesn't have a penny, house is in my name so he will benefit from the divorce. I will be lucky to keep my flat). He has harassed me in various ways over the past few months, suicide threats, threats to burn the flat down among them. I've reported two of these to the police. He's also separately been picked up by the police on several occasions due to his mental health and has been seen by a mental health team. I think he basically needs to be sectioned but as some of you know its not that easy to get someone sectioned. I have tried to help him as far as I can with his mental health issues, but there's a limit to what I can do.
I don't want him to be on the street, but I am very worried about him moving back, for obvious reasons. I'm not worried he will hurt me or DD (who is his), but just that his selfish and odd behaviour will freak her out, that it will be unsettling for her once he's moved back in and that he will generally make my life a nightmare once he's in the house.
He literally has nowhere else to go and no money and I don't want him to die or be homeless but I'm very worried.
Do I have any legal recourse to prevent him moving back in? Seeing a solicitor tomorrow but would be good to get some advice here too.
