A contract to buy and sell shares is an agreement for the sale and purchase of a given number of shares at an agreed price. The shareholder who sells his shares is the seller and the party that buys the shares is the buyer. This agreement specifies the terms of sale and purchase of the shares. What distinguishes this document from a share purchase agreement is that a share purchase agreement is used in cases where a company sells its shares, while a shareholder of the company sells shares already issued to another party as part of a share sale and sale agreement. Once all parties have signed the document, each party should keep at least one copy of the original signed document for its minutes. After the post-foundation bid, the buyer`s name is added to the list of company members (if the buyer is not yet a member of the company).
