AIBU to ask for specifics needed to end marriage?

[Helppleasethankyou]

I need an exact step by step of what to do here. We can’t continue, he won’t be able to move out for a few months. I have no idea what I’m doing. I often see people say get all important docs, but what specifically?
Also, how does it work with the mortgage? It’s in both names, I can literally just about cover it and bills and know I’m entitled to stay here with kids until 18, but what happens with that? Does he just get back half of equity now or is he expected to pay half to get the total half?
His MH is really really bad and I’m very scared (not for safety) about how he will start treating our children, as in playing inappropriately, which was a boundary I set. Background for this was him calling them losers and not respecting when they say stop until they cry (god awful I know), he stopped when I threatened divorce, his MH has gone downhill and he’s started again, whilst checking out of family life completely.
I’m just terrified.

You need to gather together all personal documentation for you and any DC, birth certs/passports etc. Any financial documentation you can find regarding bank accounts, pensions, wage slips/P60s plus any other financial stuff. Keep them in a safe place outside the house so he can’t get hold of them.You might not think he’s capable of trying to sabotage you but I’d be taking nothing for granted. Then you need to consult a solicitor. Nobody here can advise you as we don’t know your circs but a solicitor can.
Good luck and stay strong x.

Oh, and the financial docs need to be for both of you. Take pics or scan anything of his that you can find.

You're not entitled to stay there so don't assume you will.

How everything works - what you get, what he gets, what he has to pay - will depend on the agreement or court settlement you reach. There is no set formula.

You would be best consulting a specialist solicitor.

The government actually has a fairly helpful resource here: www.gov.uk/divorce

I would maybe ask to move this to legal advice because you'll get fewer but generally more informative and accurate answers there.

Good luck op
