A purchase-sale contract is a document used when a company wishes to enter into an agreement with the owners of the business on how its stake in the business, called “Ownership Units”, can be sold or transferred. These documents govern what happens in different situations, even if an owner wishes to voluntarily sell their ownership of the business during their lifetime. The company can have different forms – a company, LLC, partnership, etc. – the same types of questions are asked. Suppose that in the event of the death of a co-owner of a company or a strange situation, that an individual or a group of co-owners is forced to leave the company, all partners will sign a purchase-sale contract covering all business that leaves the company or decides to leave the company. Life insurance is a common way for many companies to plan the execution of the purchase-sale contract. In the case of several co-owners, for example, the market value of the business of the business would be estimated. Each partner would then be insured by the other owners or the company for its share of the total value of the business. .
