Undue Performance and the Conditions for Its Realization
Undue performance is a concept recognized in the Civil Code and derives from principles of Islamic jurisprudence.
Despite its legal importance, many individuals are unfamiliar with this term. The purpose of this article is to explain the concept of undue performance, its applications, and the conditions required for its realization.
Legal Consequences Arising from Undue Performance
The Concept of Undue Performance
As the term suggests, undue performance consists of two elements: performance and lack of legal justification. In its literal sense, performance means the fulfillment of an obligation or the complete discharge of another person’s right. Undue refers to an act carried out without legal entitlement or lawful cause. Accordingly, when a person transfers property or pays money to another without the existence of a legal obligation or lawful cause, such payment is considered undue performance.
In contrast, proper performance occurs when a valid debt exists, and the debtor discharges it by making a payment to the creditor.
Conditions for Restitution of Money or Property Due to Undue Performance
Given that the law permits the performance of a debt by a person other than the debtor, a claimant alleging undue performance must prove not only the absence of any personal debt but also the absence of intent to discharge the debt of a third party. If a person voluntarily and without compulsion pays the debt of another, that person cannot later seek restitution merely on the ground that they were not personally indebted.
This is because the law recognizes the permissibility of performance by a non-debtor.
A payer may seek recourse against the principal debtor only where payment was made with authorization. In such a case, after satisfying the creditor, the payer may claim from the debtor the amount paid on his or her behalf. Where payment is made without authorization, no right of recourse against the principal debtor exists.
With respect to mistakes in payment, it should be noted that a mere error in delivering goods or paying money does not, by itself, constitute undue performance. Some legal scholars are of the view that, pursuant to Article 265 of the Civil Code, the payer may claim restitution only if he or she can prove the absence of any existing debt.
Accordingly, a claimant may seek restitution upon establishing the following circumstances:
- Undue performance occurs where the payer or transferor owes no debt to the recipient. In some cases, a debt may have existed but was extinguished before payment. If payment is made after the debt has been discharged, the performance is deemed undue. An example is where a third party pays the debtor’s obligation, and the debtor, unaware of such payment, subsequently pays the same debt again.
- Where a debtor pays a debt before its agreed maturity, the debtor may seek restitution of the amount paid as a result of undue performance.
Establishing the Undue Nature of Performance
Pursuant to Article 265 of the Civil Code, whenever a person transfers property to another, the law presumes that the transfer was not gratuitous and was made for a lawful reason. Therefore, if a person transfers property to another without being indebted, that person is entitled to restitution.
Where an individual mistakenly believes that they are indebted and makes payment on that basis, the recipient’s retention of the property lacks legal justification, and the property must be returned to the payer.
Restitution requires proof of the undue nature of the payment by the payer. In addition, the payer must establish that the recipient was not legally entitled to receive the property.
Examples of Undue Performance:
- Payment of a debt, due to mistake, coercion, or deceit, to a person other than the rightful creditor.
- Payment of money or transfer of property under the mistaken belief of being indebted.
- Payment of a debt that has already been extinguished.
Legal Effects of Undue Performance
- The recipient is obligated to return the property to the payer.
- The recipient must also compensate for any benefits derived from the property, as the rightful owner was deprived of its use during the period of unjust possession and is entitled to reasonable compensation.
- Transactions conducted with respect to property obtained through undue performance are legally ineffective.

Undue performance refers to a situation in which a person transfers property or pays money to another without any legal obligation or lawful cause. In such cases, the payment is unjustified, and the payer may seek restitution.
Proper performance occurs when a debtor discharges an existing debt. In contrast, undue performance arises where the payer owes no debt to the recipient or where the debt has already been extinguished.

Under Article 265 of the Civil Code, if a person transfers property to another without being indebted, restitution may be claimed. The payer must prove both the absence of a debt and the lack of entitlement on the part of the recipient.
Examples include mistaken payment to a person other than the creditor, payment made under the erroneous belief of indebtedness, and payment of a debt that has already been discharged.
