If you have just begun the divorce procedure you will know it comes in 2 parts. One is the actual civil divorce and the other is the financial settlement. I'm presuming he has accepted the divorce as going ahead.
Have you already negotiated the financial settlement? Signed and sealed an agreement?
If not, I suggest you get advice on it very quickly indeed.
Are you still living in the house with him? if he has gone and has accommodation already then think twice about selling the house.
It is actually very hard to remove you from the house if you are in it and he has accommodation and you have no where to go and not adequate means to get accommodation (and on top of it can prove M Health stuff) then it will be hard to get you out.
He would have to take out a court order against you and it would cost him and it takes a long time.
The courts are moving very slowly atm indeed - with everything, btw, your divorce may take longer than you had anticipated.
I was a Safeguarded Adult during the break up process due to his threats and abuse and had the police round twice, changed locks etc. but I also had to help him - he has MH workers and although they advised me to bring the police in against him, I did help him get warden assisted accommodation, at which point he had secure housing and I needed to stay, but thats why I went into it with my solicitor as to being able to stay as long as possible in my house if he did end up having claims against it.
