very complicated case

I am divorcing my husband and our financials are extremley complicated.
House worth 450 but only approx 70 equity
We started a business together 6 years ago, him and his friend are directors, I just worked there. Started small and grew to turning over millions. He takes a salary of approx 80.000 plus his fuel, phone etc. He pays himself a monthly pension contribution of 1250 per month.
When I worked there I recieved a salary of 40k and also a pension monthly 1250.00.
His friend and his wife get the same as we did.
Obviously when I walked away I lost this high income, will this be looked at?
I have been fighting him for two years through solicitors and recently realised i have wasted close to 10,000 and I am still in the same position i was back then, so I have recently submitted Form A myself.
His voluntary form E was a joke, claiming the company is worth 500 pounds and he has an income of 700 pounds per month. Its clear to see close to 7k going into his account each month so a blatent lie.
I now earn maybe 10k per year with absolutley no mortgage capacity at all. I have the three children 90 percent of the time.

Could anyone give me some advise please? Can you get a valuation of a business done by looking at companies house? obviously they spend most of the money so they don't pay alot of tax... Also the company is likely to turning over millions more due to the pandemic as its online sales?
He is currently paying the mortgage but is desperate to stop.

can anyone help?
