How can we figure out the value of the family business?

Since it is unlikely that you have sold stock on a stock exchange, which would be a quick and easy way to determine business value, you may have to hire a valuation expert to determine the value of the business and give evidence of his or her findings to the court. Your spouse will probably do the same, and it would be up to the court to find for one or the other once the appraisals are presented in court.

Tax returns can help in valuation issues, as can any loan applications you may have made. If you have any recent offers to buy the business by a third party that would be excellent evidence of the value of the business.
