It is useful to implement a buy-sell contract if these agreements are often comparable to marriage contracts for companies. They determine what happens to the ownership of the business when one of the owners (or individual entrepreneurs) undergoes life changes that may influence the continuation of the business itself. Life changes can range from divorce or bankruptcy to death. The buy-sell agreement protects the business and the remaining owners from the effects of an owner`s personal life that can impact the business. A buy-sell contract is a legally binding contract that defines the parameters under which shares can be bought or sold in a company. A buy-sell agreement is an attempt to avoid potential chaos if one of an organization`s partners wants or needs to leave the business.
