The prudent rule prior to entering a business is to establish a formal agreement for getting out of the business relationship. Buy and sell agreements allow the business owner to transfer an interest in the business to other owners or to the business itself. The agreement can guarantee a buyer for the business and eliminate difficulties associated with transferring the business upon death or disability of one or more of the owners. Conflicts among interested parties to the business may be minimized by clearly establishing the definition of market value prior to the time of need.
