This just sounds dreadful. Get good financial advice and a good solicitor and get out of this marriage. Life is too short to put up with this kind torment.
All the best 💐
There appears to be little love in your marriage. You say he's researching divorce process, i.e. planning to end the marriage to his financial and time advantage. Time for you to take control and do the same.
This is good, straight forward advice from Fallingstar along side as others have said * get your ducks in a row*. Meanwhile and in tandem:
1) Collate electronic copies of all detail of financial assets, income, outgoings, tax paid, pensions, savings, business profits, valuation, trust detail etc.
2) Share with your solicitor if and when you begin divorce proceedings to use in negotiations and/or with a divorce mediator to directly negotiate with your husband how to split the your joint financial assets directly.
3) You mention an £800k business, that you helped build up is "in a trust' for your children. Trusts can be reviewed, changed or ended or reassigned- take legal advice. Notwithstanding the business and trust value whilst you are both still alive in a joint marital financial asset. Your health and well being during and after a divorce process is paramount and your husband needs to understand review of the trust is required to ensure you can be adequately and fairly housed. That is just and respectful.
4) Add up the value of all your assets, including the value of the £800k business and bungalow in which you live. You then know the total which is up for negotiation.
5) You are each entitled to the half the total value of those assets and you can negotiate to stay in the bungalow, if that remains your choice, as part of that total sum to be divided accordingly.
6) On divorce you and your then ex husband will each need to make a new will. If either or both of you wishes to set up a trust to benefit your children, and that remains appropriate once the martial assets are divided that is an option for both of you to consider.
7) In reality your children can still benefit form the separate inheritance of mum and Dad when divorced- the facts the business is currently in a trust should not alter change or delay the divorce asset sharing negotiation.
Good luck and take care 💐
