Core content: The rules for contract performance include legal obligation rules, personal performance rules, actual performance rules, and so on.

Statutory obligation rules

Legal obligation: refers to the legal contractual obligation that the parties should bear, even if there is no agreement in the contract, according to legal provisions. (Article 60, Paragraph 2 of the Contract Law: The parties shall abide by the principle of good faith and fulfill obligations such as notification, assistance, and confidentiality in accordance with the nature, purpose, and transaction habits of the contract.)

① Assistance obligation: refers to the obligation of the contracting parties to assist the other party in fulfilling their obligations, in order to ensure the smooth performance of the contract.

② Convenience obligation: refers to the obligation to provide convenience for the other party to fulfill contractual obligations.

③ Notification obligation: The contracting parties shall promptly notify the other party of their performance of obligations.

④ Duty to reduce losses: In Contract Law, the term "preventing the expansion of losses" refers to the situation where one party suffers losses due to subjective and objective reasons, and the party suffering losses should take necessary measures to prevent the expansion of losses.

⑤ Confidentiality obligation: refers to the obligation of the contracting parties to keep confidential the secrets of the other party that they have learned through the establishment of the contractual relationship.

Proper performance

Also known as appropriate performance, it refers to the obligation of the parties to fulfill their contractual obligations in accordance with the provisions of the contract.

① The performance subject is correct (personally fulfilling the rules); But when the performance of contractual obligations by a third party does not harm the interests of the creditor, and when the third party accepts that the performance of contractual obligations does not harm the interests of the debtor, it is also correct for the third party to be the subject of contractual performance.

② Correct performance of the subject matter (principle of actual performance);

③ The fulfillment time is correct;

④ The place of performance is correct;

⑤ The fulfillment method is correct.

Personally fulfill

The contractual obligations must be fulfilled by the contractual debtor to the contractual creditor and cannot be replaced by a third party.

Performance with unclear terms and conditions

① Performance of quality unclear clauses; (Article 62, Paragraph 1: If the quality requirements are not clear, they shall be fulfilled in accordance with national or industry standards; if there are no national or industry standards, they shall be fulfilled in accordance with ordinary standards or specific standards that meet the purpose of the contract.)

② Performance of price unclear clauses; (Article 62, Paragraph 2: If the price or remuneration is unclear, the performance shall be based on the market price at the place of performance at the time of signing the contract; if government pricing or government guidance pricing should be implemented according to law, it shall be performed in accordance with regulations.)

③ Performance of terms with unclear location; (Article 62, Paragraph 3: If the place of performance is unclear and the currency is paid, performance shall be made at the location of the receiving party; if the immovable property is delivered, performance shall be made at the location of the immovable property; and for other objects, performance shall be made at the location of the performing party.)

④ Performance of terms with unclear deadlines; (Article 62, Paragraph 4: If the performance period is unclear, the debtor may perform at any time, and the creditor may also demand performance at any time, but the other party shall be given necessary preparation time.)

⑤ Performance of terms with unclear methods; (Article 62, Paragraph 5: If the method of performance is unclear, it shall be performed in a manner that is conducive to achieving the purpose of the contract.)

⑥ Performance of unclear cost clauses; (Article 62, Paragraph 6: If the burden of performance costs is unclear, the party performing the obligation shall bear it.)

Third party performance

Concept: Third party performance refers to the situation where the person performing the contractual obligations or the person accepting the performance of the obligations is not a party to the contract, but a third party outside of the parties to the contract during the contract performance process. As long as there is an agreement in the contract, a third party can become the subject of contract performance. (Article 64: If the parties agree that the debtor shall perform the debt to a third party, and the debtor fails to perform the debt to the third party or fails to perform the debt in accordance with the agreement, it shall be liable for breach of contract to the creditor. Article 65: If the parties agree that the third party shall perform the debt to the creditor, and the third party fails to perform the debt or fails to perform the debt in accordance with the agreement, the debtor shall be liable for breach of contract to the creditor.)

Fulfillment of price changes

Concept: It refers to the issue of the price at which government pricing adjustments occur after the contract is signed and before its performance, in order to fulfill government pricing contracts. (Article 63: For the implementation of government pricing or government guided pricing, if the government adjusts the price within the delivery period specified in the contract, the pricing shall be based on the price at the time of delivery. If the delivery of the subject matter is delayed, the original price shall be implemented when the price increases; if the price decreases, the new price shall be implemented. If the subject matter is delayed in extraction or payment, the new price shall be implemented when the price increases; if the price decreases, the original price shall be implemented.)
