Where a creditor delays in accepting the performance of one of the debtors subjected to joint and several liabilities, such delay takes effect on the other debtors subject to joint and several liabilities.

agreement cannot be reached within a reasonable period of time, the parties may request the people's court or an arbitration institution to rectify or rescind the contract.

Article 535

Where a debtor's right against a counterparty or an accessory right related thereto has not been claimed against the counterparty owing to the debtor's indolence, and the enforcement of the creditor's due claim is thus adversely affected, the creditor may request the people's court to allow him to exercise by subrogation the debtor's claim against the counterparty of the debtor in his own name, unless such claim belongs exclusively to the debtor himself.

The scope of the right of subrogation is limited to the creditor's due claim. The necessary expenses for the creditor to exercise the right of subrogation shall be borne by the debtor.

Prior to the due date of the creditor's claim, where there exists a circumstance under which the limitation period for the debtor's principal claim against a counterparty or an accessory claim related thereto is to expire, or the debtor fails to timely declare his claim in a bankruptcy proceeding, and hence, the enforcement of the creditor's claim is adversely affected, the creditor may, by subrogation, request the counterparty of the debtor to perform its obligation to the debtor, declare the debtor's claim to the bankruptcy administrator, or take other necessary acts.

Article 537

Article 538

Where a debtor gratuitously disposes of his proprietary rights and interests by waiving his claims, waiving the security for his claims, or transferring his property without consideration, and the like, or maliciously extends the period of performance of his due claim, and hence, the enforcement of the creditor's claim is adversely affected, the creditor may request the people's court to revoke the debtor's act.

Article 539

Where the debtor fails to make such a designation, the obligation that has become due shall be performed first. Where multiple obligations have become due, the obligation not secured or with the least security shall be performed first. Where none of the obligations are secured or the obligations are equally secured, the obligation with which the debtor assumes the heaviest burden shall be performed first.

Article 565

Where one of the parties requests to rescind the contract in accordance with law, the other party shall be duly notified.

A creditor may collect the subject matter placed in escrow at any time, except that where an obligation owed by the creditor to the debtor becomes due, the escrow agency, upon request of the debtor, shall reject the creditor's request for collecting it before the creditor performs such obligation or providing security therefor.

The creditor's right to collect the subject matter placed in escrow is extinguished if such right is not exercised within five years from the date the subject matter is delivered to the escrow agency, and the subject matter shall be escheated to the State after the escrow agency's expenses are deducted. However, where a creditor fails to perform his overdue obligation to the debtor, or where the creditor waives his right to collect the subject matter placed in escrow in writing to the escrow agency, the debtor has the right to take back the subject matter after paying the escrow agency's expenses.

(3) the creditor fails to request for performance within a reasonable period of time.

Where one of the situations specified in the preceding paragraph exists so that the purpose of the contract cannot be achieved, the people's court or an arbitration institution may terminate the contractual relationship of rights and obligations upon request by a party, but the default liability to be borne is not affected.

Where the agreed amount of liquidated damages is lower than the losses caused, the people's court or an arbitration institution may, upon request of a party, increase the amount. Where the agreed amount of liquidated damages is excessively higher than the losses caused, the people's court or an arbitration institution may, upon request of a party, reduce it appropriately.

Where the parties agree on the liquidated damages for delayed performance, the breaching party shall continue to perform the obligation after paying the liquidated damages.

Article 586

The parties may agree that one party provides earnest money with the other party to secure the claim. An earnest money contract is formed upon actual delivery of the earnest money.

The amount of the earnest money shall be agreed by the parties, except that it may not exceed 20% of the value of the object of the principal contract, and any excessive amount does not have the effect of earnest money. Where the amount of the earnest money actually delivered is more or less than the agreed amount, the agreed amount of the earnest money is deemed to have been changed.

Article 587

After a debtor has performed the obligation, the earnest money shall be calculated as part of the price or be refunded.
