What's your status? Are you divorced? Still married? Legally separated?
If you're already divorced or never married, then the VALUE of the business would not be relevant. The earnings of the business very well could (and probably should) be considered, but it depends on the business structure.
If, for example, you set up a business as an LLC and chose reporting as a partnership, with two people owning equal percentages, and the business had earnings of $100,000, then you would each have $50,000 in income to report on your taxes - regardless of how much cash you actually received. There are a lot of other variations, so you'd have to explain the structure of the business, as well.
