If someone owes money, he or she can sue the court for repayment within the limitation of action. After winning the lawsuit, if the other party fails to perform the judgment of the court during the performance period, he or she can apply to the court for compulsory execution. Or you can apply to the court for a payment order to urge the other party to repay.
 [Legal Basis]
 In Article 188 of the Civil Code, the limitation period of action for requesting the people's court to protect civil rights is three years. If the law provides otherwise, such provisions shall prevail.
 The limitation period of action shall be counted from the date when the obligee knows or should know that his rights have been damaged and the obligor. If the law provides otherwise, such provisions shall prevail.
 However, if it has been more than 20 years since the date of damage to rights, the people's court shall not protect them. Under special circumstances, the people's court may decide to extend them on the application of the obligee.
