Purchase and sale contracts are often used by sole proprietorships, partnerships and entered into companies to facilitate the transfer of ownership when each partner dies, retires or decides to leave the business. One of the best ways to make it easier to buy and sell a deceased partner`s interest in a business is to use an entire life insurance policy. For two business partners, both life insurances go through the life of the other. For example, the agreement may prevent owners from selling their interests to outside investors without the agreement of the remaining owners. Similar protection may be granted in the event of the death of a partner. Persons wishing to marry and marry in the community of property conclude a marriage contract drawn up by a notary and duly registered. . . .
