Why do you have to leave Thesoundofrain? Can you not report him and get a residency order (I think its called). You will make yourself homeless, when he’s abusing you? He should face charges for this.
I hate to say it, but I would assume he would change the locks once you leave, and if he shows police his name on documents they will probably agree that you have no right of access, even though marriage probably does, when done in family court mean you would have the property divided properly upon divorce. I guess you would plan to divorce after you’ve left?
You need legal advice, and ifyou cannot find/afford/get legalaid, call rights of women and ask their advice on your position in this before you make any permanent steps, unles syou are in immediate danger, then you just have to go and work it out after, which you’ll get support to do when in refuge with a key worker.
warmest wishes ts
