• A legal entity sale and purchase agreement is an agreement between a partnership or corporation as a legal entity and the owners (partners or shareholders) whereby, in the event of the death of the owner, the company (partnership) will acquire the deceased owner’s interest in the business. . Ownership of the company is still retained by the surviving owners. As a result, each survivor receives a large stake in the company, and the deceased owner’s estate is supplied with the cash he will need.
