Divorce and joint business

[Storm587]

Going through a divorce and he's arguing that because he works more hours in our joint business than I do that it would no longer be fair to split profits 50:50 (which has been the case since we started it many years ago).
My problem is that I don't know how much of the time he is 'at work' is taken up by other non-work things. For example, he told me he used the computer at work when searching for escorts as he would never use home devices to do that.
WWYD in this situation. I can't ask him as I'd never get the truth because he's a liar.

Get a forensic accountant.

A forensic accountant wouldn't be able to assess what I need to know.

Do you have a sense for how long the tasks he claims to have done would actually take? If he's claiming to have worked 100 hours but you know that he should have accomplished x y and z in that time and didn't, then you have a basis for a counter-negotiation. Or if he has games installed on his office computer. Alternately, you could take a sampling of his work browser history over a few weeks. You'll never get the "correct" valuation but you could get closer.

I think you need a solicitor and take this into account during the settlement.

Did you facilitate him working linger hours, I.e. looking after children etc.
Are there sales. Who brought them in.... there are so msny variables.
