If the company's cooperative shareholding contract is not renewed upon expiration, the parties may extend the contract term through supplementary agreement. Upon the expiration of the investment contract, both parties may continue to sign supplementary agreements to extend the contract term. Legally speaking, if the contract is not renewed, but continues to be performed according to the rights and obligations of the original contract, the contract will take effect. If the company still exists, the contract should continue.

legal ground

Article 490 of the Civil Code stipulates that if the parties conclude a contract in the form of a contract, the contract is established when the parties sign, seal or press their fingerprints. Before signing, sealing or fingerprinting, one party has fulfilled its main obligations, and the contract is established when the other party accepts it.

A contract shall be concluded in written form as stipulated by laws, administrative regulations or agreed by the parties. If the parties do not do this in writing, but one party has fulfilled its main obligations and the other party accepts it, the contract is established.
