Going thro a similar thing myself, only that I worked most of the marriage while my wife didn't and the house is in her name. I left with a mountain of debt and am claiming a % of the value of the house. I'm sure many women will say thats wrong but I did pay for the house over 10 years and she has access to substantial funds. Regardless, he will be entitled to something, the court will start with a 50/50 split then weigh up each side, most of it will go in your favour. But I'm sure he can demonstrate he contributed a bit which means he's entitled to a bit. I did my divorce myself with some advice from solicitor to check forms etc. Any financial claim can be sorted separate from the divorce providing its not filed until you've signed for the Degree Nisi so don't get the two issues confused. Also, your business may be safe but the judge could rule (although extremely unlikely based on what you've said) that you have funds in the business available to pay what they decide he is entitled to.
