Legal principle allows a company to retroactively validate an unauthorized contract by taking actions that indicate acceptance of the terms, such as making payments or receiving goods. Subsequent performance ratification is a concept in Chinese contract law that prevents a company from using a lack of authorization as a technicality to escape a deal it has already begun to fulfill. Under article one hundred seventy one of the civil code, if a person acts without authority but the company later acknowledges the act or performs its own obligations under the contract, the deal becomes binding.
This rule is designed to promote fairness and to protect counterparties who have already invested in the transaction. The ratification stops the company from “cherry picking” which parts of an unauthorized deal it wants to follow. It applies as soon as the first significant act of performance is completed by the entity.
Proof of ratification often comes from the financial and operational records of the company rather than from a formal board resolution. If a firm receives raw materials from a supplier and uses them in production, it has implicitly ratified the contract that the supplier signed with an unauthorized agent. Similarly, making a partial payment on an unauthorized loan is a strong indicator of subsequent performance ratification.
The court will look for any “clear and unequivocal” act that shows the company intended to treat the contract as valid. This can include sending emails to coordinate delivery, accepting a security deposit, or providing a guarantee for the deal.
Legal consequence of these actions is that the company is “estopped” from later claiming that the contract is invalid. This means the entity cannot wait to see if a deal is profitable before deciding whether to honor the unauthorized signature. Once the ratification has occurred, the contract has the same legal force as if it had been properly signed by the legal representative.
This protects the stability of the market by ensuring that companies are responsible for the actions they allow to happen on their behalf. The estoppel effect is a powerful tool for contractors who find themselves in a dispute with a company that is trying to avoid its debts.
Application of this principle helps to resolve the ambiguity that often surrounds unauthorized transactions in the Chinese market. It creates a clear boundary: if you take the benefit of the contract, you must also take the burden. This certainty allows businesses to continue working even when there are questions about the internal authority of their counterparts.
However, subsequent performance ratification does not apply if the company acted only to mitigate its losses or if it protested the unauthorized act immediately. The company must have had knowledge of the unauthorized act before the performance can be considered a ratification. This knowledge can be proven through internal memos or the fact that the person who signed the contract was a senior manager.
The final result of a ratification case is usually the full enforcement of the contract, including any penalties for late payment or breach. This principle encourages companies to be more careful in their internal communications and to act quickly if they discover an unauthorized deal. It balances the rights of the company to control its identity with the reality of commercial behavior.
Subsequent performance ratification remains a key mechanism for maintaining the integrity of the Chinese contract system.
