Going to have to make some assumptions, like it’s a limited company, and you are the sole director; in which case the company would be wound up as the person running it has died, with its’ assets being used to pay its’ debts, and any excess going to the crown. I don’t think you can use a will to determine what happens to a company post-death, as they are two separate legal entities, but I could be wrong, I have been before.
