Divorce- what happens to savings

[Losforwords]

Hello,
After many horrible years I have finally decided that this year is the time to get divorced and give myself a chance for a better life.
I am trying to figure out how would our assets be shared and I am really worried about a significant amount of savings that are held in my soon to be ex husband bank account, which is in his own name and I do not have access to it. He is very protective over money, and I am totally sure that when he finds out about me wanting the divorce, he will try and conceal this money by probably transferring it elsewhere. Can he get away with that at all?
Also, what would be the fair arrangement if I wanted to stay in the house with the children? We have mortgage on the house with a fair bit of equity.
Please share your experiences as I am completely lost and not sure where to start.

Sorry to drip feed but just to add some perspective, we have been married since early 20s we are mid 30s now and both came into relationship with no assets/savings. Everything we have got today is by both of us working, apart from me taking 3 years off to raise two children. Both earning similar, me paying for majority and him saving. Financial abuse, I know but I couldn’t face breaking family over money.

Can you get hold of a statement of the savings? Then go and see a solicitor. All savings (and debts) should go into the pot if you've been married for a significant number of years

Yes, just get hold of anything you can.

Having gone through this process I would advise you to get a good solicitor.
Part of the divorce process involves both you and your husband making a full financial disclosure. This takes into account earnings, savings, investments, and debt, including mortgage and pensions.

I think there is a divorce board on here, but the general starting point will 50/50 on assets & debts etc., then flexing a bit
unless there is a very compelling reason you will probably not get to keep the house as that will probably be your marriage largest asset by a mile.
if your husband wants any form of childcare he is also going to need somewhere suitable to live etc etc
