Most legal professionals would agree that the concept of condictio indebiti can be complex and confusing.
In this article, we clearly define condictio indebiti, explain the key principles of unjust enrichment that underpin it, and walk through the elements required to establish liability.
You'll learn the origins of condictio indebiti in Roman law, how the doctrine has developed over time, key case examples that illustrate its application, and potential defenses against claims. We'll also overview the remedies available, like restitutio in integrum and recovery of profits, when enrichment liability is found.
Introduction
The legal principle of condictio indebiti allows a party to recover payments that were made by mistake. This concept has its roots in Roman law, where it was used to prevent unjust enrichment and restore equity between parties in cases of mistaken payments.
At its core, condictio indebiti is based on the idea that if Person A pays Person B by mistake, believing that they owed Person B money when in fact they did not, then Person A should be able to recover that payment. It aims to prevent Person B from being unjustly enriched by keeping the mistaken payment.
To successfully claim condictio indebiti, a party must generally prove three key elements:
- A payment was made
- The payment was not legally due (it was made by mistake)
- The payment resulted in unjust enrichment of the receiving party
If these elements are met, the law may allow recovery of the payment to restore both parties to the positions they were in prior to the mistaken payment. This helps to equitably unwind the transaction, prevent undue loss or gain, and uphold good faith between parties.
The concept of condictio indebiti continues to play an important role today in remedying mistaken payments across various legal systems and types of transactions. However, specific requirements, defenses, and remedies vary by jurisdiction.
What is condictio indebiti in Roman law?
Condictio indebiti refers to a legal action in Roman law that allowed the recovery of payments made by mistake. Specifically, it enabled a person (A) to recover money or property that was mistakenly given to another person (B) to which they were not entitled.
Some key things to know about condictio indebiti:
-
It was used when someone paid something by mistake that was not actually due or owed. For example, if someone accidentally paid an invoice twice.
-
The person making the payment by mistake (A) could bring a legal action against the recipient (B) to get the payment returned.
-
It was considered an enrichment or unjustified benefit for the recipient (B) to keep the mistaken payment. Condictio indebiti aimed to reverse this to prevent unjustified enrichment.
-
There needed to be a factual error behind the payment, i.e. the payer did not legally owe the amount paid. If they did owe it, condictio indebiti could not be used.
-
The claimant had to show that the payment was made because of an excusable mistake on their part in order to succeed with the action.
So in summary, condictio indebiti was an important legal remedy in Roman law that allowed recovery of payments made by mistake, preventing unjustified enrichment of the recipient. It still forms the basis of similar legal actions today in many modern legal systems.
What is the law of Solutio indebiti?
Solutio Indebiti refers to the legal principle in Roman law stating that if someone mistakenly pays a debt that is not actually owed or due, the recipient has a duty to return the erroneously paid amount.
The key aspects of Solutio Indebiti law include:
-
It applies when a payment has been made under an objective mistake of fact or law, meaning the payer was genuinely unaware that the amount was not actually owed. This is known as an "excusable mistake".
-
The recipient is seen as being "unjustly enriched" by the amount they were not entitled to receive. Solutio Indebiti aims to prevent this unjust enrichment.
-
It creates an obligation for the recipient to make restitution of the undue payment amount. This typically requires returning the exact amount received, putting them back in the position they would have been without the payment.
-
There are certain exceptions - for example, if the recipient has disposed of the funds in good faith before becoming aware it was paid in error.
The principle of Solutio Indebiti aims to promote equity by reversing transactions found to be lacking legal basis. It continues to influence modern restitution laws regarding recovery of mistaken payments. Key cases like Masters and Seamen of Dundee v Cockerill helped establish the current framework.
Is a condictio indebiti an equitable remedy?
The condictio indebiti is an equitable remedy in civil law that allows a plaintiff to recover a payment that was made by mistake. It is based on the principle that no one should be unjustly enriched at the expense of another.
To successfully bring a condictio indebiti claim, the plaintiff must prove:
- A payment was made by mistake
- There was no legal ground for making the payment
- The defendant benefitted from the payment
If these elements are met, the law implies a contract between the parties requiring the defendant to return the payment. The plaintiff can then seek restitution to recover the amount paid in error.
The condictio indebiti emerged from Roman law and is still an important equitable remedy in many civil law jurisdictions today. It aims to correct unjust enrichments and prevent one party from unfairly benefitting from another party's mistake.
So in summary, yes the condictio indebiti is an equitable legal remedy used to recover mistaken payments and prevent unjust enrichment. It is a key example of how civil law systems incorporate equitable principles.
What is the difference between condictio sine causa and condictio indebiti?
Condictio indebiti and condictio sine causa are two legal concepts in Roman law that allow a plaintiff to recover an unjustified payment or transfer of property.
The key difference between them is the requirement to show a mistake on the part of the plaintiff:
-
Condictio indebiti requires the plaintiff to show that they made a reasonable mistake in making the payment or transfer. For example, paying an invoice by accident or paying the wrong person.
-
Condictio sine causa allows recovery even if there was no mistake by the plaintiff. It applies whenever the defendant has been enriched without legal justification, whether due to a mistake or not.
So in summary:
-
Condictio indebiti lies when there is a mistaken payment or transfer. The plaintiff must show they were reasonably mistaken.
-
Condictio sine causa allows recovery whenever the enrichment of the defendant is without cause, whether due to a mistake or not.
Both legal concepts aim to prevent unjustified enrichment, but condictio sine causa casts a wider net as it does not require a mistake on the part of the plaintiff. It is enough that the defendant's enrichment lacks sufficient legal grounding.
Understanding the Condictio Indebiti Principle
Condictio indebiti refers to the legal principle of recovery of payments made by mistake. It allows a party who has made a payment that was not legally owed to recover the amount paid.
The key elements of a condictio indebiti claim are:
- The claimant made a payment to the defendant
- The claimant was under no obligation to make the payment
- The payment was made by mistake
- The defendant would be unjustly enriched if allowed to retain the payment
Some examples of situations where condictio indebiti could apply:
- An overpayment is made due to a clerical error
- A payment is made twice by accident
- A payment is made under a contract that is later found to be null and void
A successful condictio indebiti claim requires the claimant to prove the payment was genuinely not owed rather than a change of mind after the fact. There must be no legal basis for the defendant to retain the funds.
Literal Translation and Restitutio in Integrum Meaning in Law
The Latin term "condictio indebiti" translates to "action for recovery of undue payment". It is derived from Roman law and is based on the principle of "restitutio in integrum" which means restoration to original condition.
In legal terms, restitutio in integrum refers to the aim of condictio indebiti to reverse unjustified enrichment and restore the parties to the position they were in before the mistaken payment occurred. The defendant must give up the amount they were unduly paid and the claimant recovers the funds they paid out in error.
Key Principles of Unjustified Enrichment
The key principles underpinning condictio indebiti and preventing unjustified enrichment are:
-
Recovery of payments made by mistake: Condictio indebiti allows recovery of funds paid by accident or error when no debt existed. This prevents unexpected windfalls.
-
Absence of legal obligation to pay: There must be no contractual, legal or equitable basis for the defendant to retain the payment. An obligation cannot arise retrospectively.
-
Preventing unjust enrichment: Allowing a party to retain undue payments would result in unfair enrichment at the expense of the payer. Condictio indebiti restores the status quo.
These principles ensure that parties do not profit from genuine mistakes and that liability aligns with legal obligations. Condictio indebiti provides an equitable remedy to reverse incorrect payments.

Elements of Condictio Indebiti and Solutio Indebiti
Condictio indebiti is a legal concept that allows recovery of payments made by mistake. For a successful condictio indebiti claim, the following elements need to be proven:
Payment Made in Error: Excusable Mistake
The payor must prove that they made a payment in error, meaning they were not legally obligated to make the payment in the first place. The mistake also needs to be excusable or justifiable, rather than gross negligence. Examples could include clerical errors, accidental overpayments, payments made under a mistake of fact, etc.
Payment Received and Enrichment Liability
The payment in question must have been received by the payee. By retaining an unowed payment, the payee obtains "enrichment liability" - they are liable for the unjustified enrichment or benefit gained from the erroneous payment.
Absence of Legal Ground or Contract Law Justification
Additionally, the payee must not have any legal ground or contract law justification to retain the erroneous payment. For example, if there was a valid agreement or contract between the parties stipulating the payment, condictio indebiti would not apply.
The related concept of solutio indebiti refers specifically to the act of making an undue payment by mistake. So while condictio indebiti is the legal action to recover undue payments, solutio indebiti is the mistaken payment itself which leads to enrichment liability if retained by the payee.
Historical Perspectives on Condictio Indebiti
Origins in Roman Law
Condictio indebiti originated in Roman law as a legal action to recover payments made by mistake. Under Roman law principles, a person who paid something not owed could recover their payment through the condictio indebiti action. This enabled people to correct mistakes and prevent unjust enrichment of the recipient.
The concept emerged from the principle that no one should be enriched through another's loss. It aimed to restore the payor to their original financial position before the erroneous payment. Over time, Roman jurists refined the rules around what constituted an undue payment recoverable under condictio indebiti.
Key elements included establishing the payment was not legally due, made in error or under a mistaken belief of obligation, and did not unjustly prejudice the recipient if recovered. Condictio indebiti helped cement restitution and unjust enrichment remedies in Roman law.
Development in Civil Law Jurisdictions
Condictio indebiti's influence continued in modern civil law systems derived from Roman law. Most civil law countries recognize some form of the action to recover mistaken payments and prevent unjust enrichment.
French law allows recovery of undue payments made in error under 'payment of a thing not due.' German law has similar provisions under 'performance not owed.' Many Latin American countries also incorporate condictio indebiti principles into their civil codes.
While specifics vary across jurisdictions, core elements remain - the plaintiff must show no legal basis existed for the payment, it was made by mistake, and allowing the recipient to retain it would result in unjust enrichment. Modern condictio indebiti doctrine continues to shape restitution law.
Key Case Examples
Masters and Seamen of Dundee v Cockerill: A Study in Enrichment Remedies
In this case, seamen overpaid Cockerill for goods purchased from his shop. The seamen were able to recover the overpayment under the legal principle of condictio indebiti, a type of enrichment remedy.
The key facts are:
- Cockerill's shop overcharged the seamen
- The seamen paid the amount in full at the time
- The overpayment was later discovered
- The seamen sued to recover the overcharge
The court ruled in favor of the seamen, ordering Cockerill to repay the overcharge. This demonstrates a successful condictio indebiti claim, where plaintiffs can recover payments made by mistake that unjustly enrich the recipient.
Banco de la Nacion Argentina v Banca Nazionale del Lavoro: Condictio Indebiti in Banking
This case involved an erroneous wire transfer between two banks. The court allowed recovery of the mistaken transfer through the principle of condictio indebiti.
The key facts are:
- Banco de la Nacion accidentally sent a transfer to Banca Nazionale
- Banca Nazionale received the full amount
- The mistake was later discovered
- Banco de la Nacion sued to recover the transfer
The court ruled that Banco de la Nacion could recover the full transfer amount under condictio indebiti. This demonstrates the applicability of condictio indebiti to mistaken bank transfers, allowing recovery even from innocent recipients.
Defenses Against Condictio Indebiti Claims
Defendants in condictio indebiti cases may raise several defenses to avoid liability for repayment. Two potential defenses are the change of position defense and distinguishing between actio iniuriarum and condictio furtiva claims.
Change of Position Defense in Enrichment Cases
If the payee no longer has the funds that were paid by mistake, they may argue that they changed their position in reliance on the payment. For example, if the payee used the funds to pay off debts or make investments, they can claim they no longer have the money to repay.
Courts may find this defense valid if the payee can show:
- They received the funds in good faith without knowledge it was a mistake
- They detrimentally changed their position in reliance on the payment
- It would be inequitable to require repayment
However, the payee must prove they no longer have the funds and cannot simply return to their original position.
Actio Iniuriarum and Condictio Furtiva: Distinct Defenses
Two defenses that sound similar but have distinct meanings are actio iniuriarum and condictio furtiva.
Actio iniuriarum refers to claims for compensation for insult or injury. It is not specifically a defense against repayment claims.
Condictio furtiva allows claims against thieves to recover stolen property. This also does not apply as a defense in condictio indebiti cases which deal with mistaken payments.
While these principles may seem related, they address different areas of law. In condictio indebiti cases, defendants cannot claim actio iniuriarum or condictio furtiva as defenses. They must instead show the payment was not truly a mistake or they detrimentally changed their position relying on the funds.
Remedies and Damages in Condictio Indebiti Cases
Restitutio in Integrum: Recovery of Payment Made
The primary remedy in a successful condictio indebiti claim is restitutio in integrum, which aims to restore the plaintiff to the position they were in before the erroneous payment was made. This involves recovery of the actual amount that was paid in error.
For example, if a person accidentally transferred $1,000 to someone else's bank account, they would typically be entitled to repayment of the full $1,000 under condictio indebiti principles.
Courts will order the defendant to repay the amount to the plaintiff, reversing the unjust enrichment. This applies even if the defendant has already spent the money or no longer has it in their possession.
Interest and Profits: Enrichment Remedies
In addition to recovery of the payment itself, plaintiffs in condictio indebiti cases may also seek interest and any profits made from the erroneous payment. These enrichment remedies aim to prevent unjustified enrichment of the defendant.
For instance, if the defendant invested the erroneous $1,000 payment and earned $100 in returns, the plaintiff could recover both the $1,000 and the $100 profit under condictio indebiti.
Interest may be calculated from the time the payment was received to the time it is repaid. Awarding interest and profits prevents defendants from unfairly benefiting from the plaintiff's mistake.
Conclusion
Condictio indebiti is a legal concept that allows for the recovery of payments made by mistake. Specifically, it refers to a claim to recover money or other benefits transferred under an invalid or inexistent obligation.
To successfully bring a condictio indebiti claim, the following elements must be proven:
- A payment or transfer was made by the claimant
- The payment was made under a mistake of fact or law
- There was no valid legal ground for the payment or transfer
- The payee has been unjustly enriched as a result
If these elements are established, the law entitles the claimant to recovery or restitution from the payee. The purpose is to prevent unjustified enrichment and restore the parties to the positions they were in prior to the mistaken payment.
In summary, condictio indebiti provides an equitable legal remedy that reverses invalid payments, aiming to prevent unfair benefit or loss to either party. It is an important concept in contract law and civil law more broadly.
