Protect Yourself And Preserver Your Business With A Buy-Sell Agreement If you own a business with others, eventually a change in ownership will occur. An owner will retire, die, or move on for some other reason. A change in ownership could spell disaster for your business unless you and your co-owners have developed a plan for the transition. A buy-sell agreement is your business continuation plan. A properly prepared buy-sell agreement enables a smooth transition for the departing owner, the remaining owners, and the business.
