my ex and i own a business... am i entited to 50% of the profits?

Generally but not specific to your case, it would depend on the terms of:

1. Your partnership agreement, if any;

2. Your divorce settlement.

Your question is a bit confusing. You state that you are contractors for a moving business. Contractors have different rights than shareholders or partners. If you incorporated a business together, the shareholder's agreement should control who gets what. If you have a partnership, then the partnership or operating agreement controls.

I suspect you do not have any written agreements. Thus, the Illinois Statutes' default rules govern your interest in the partnership. The Uniform Partnership Act has provisions for calculating a disassociated partner's interest in the partnership and the managerial authority of each partner.

Since you are getting a divorce, it is important to retain an attorney to correctly value the business so that you receive a fair shake and to ensure that the marital agreement reflects the business valuation.
