Decide what circumstances trigger a buy-out of co-owner's share of the business. Death, divorce and bankruptcy are circumstances that are typically included in the agreement, but you should also specifically state whether a co-owner has a right to force a buy-out if that person simply no longer wants to be part of the business, whether through retirement or resignation.
Decide who can buy the co-owner's share of the business. You may want to limit the sale to the other co-owners and the corporation itself.
Decide how the price for the buy-out will be determined. There are a variety of formulas used to value a business, and it's best to decide on which one to use that is appropriate for your industry.
Decide what to do in the event that the co-owners are unable to agree on a buy-out price. You may want to consider hiring a neutral appraiser who is qualified to value businesses in your industry to decide the price.
Consider whether to require mediation and arbitration as a means to resolve a dispute regarding the buy-out. These alternative dispute resolution services can be less costly and time-consuming than litigating in court.
Decide how the transaction costs associated with the buy-out should be allocated between the corporation and co-owners involved in the sale. Even when the co-owners are in agreement, the buy-out will usually require the services of the business's accountant and lawyer to complete the transaction.
Consider requiring life insurance for each of the owners as a means of funding the buy-out in the event of a co-owner's death.
