Civil Law and UAE: Restitution Claims and Repayment Actions

1. Introduction

Restitution claims and repayment actions under UAE civil law concern the recovery of money, property, benefits, or their value where one person has received something without a sufficient legal basis, received an undue payment, or is required to return benefits following nullity, cancellation, termination, mistake, or another legally recognised event.

The current federal framework is the Civil Transactions Law, Federal Decree-Law No. 25 of 2025. Its provisions on beneficial acts contain a dedicated chapter on unjust enrichment and receipt of the undue. In particular:

Article 274 deals with unjust enrichment;

Article 275 deals with receipt of undue payment; and

Article 192 deals with restoration following annulment or nullity of a contract. (UAE Legislation)

The central idea is:

A person should not retain money or property when there is no sufficient legal basis for retaining it.

2. Meaning of a Restitution Claim

A restitution claim seeks to reverse an unjustified transfer of value.

For example:

Example 1 — Mistaken payment

A intends to pay B AED 10,000 but accidentally transfers AED 100,000.

B receives AED 90,000 more than was due.

A may have a repayment/restitution claim for the excess.

Example 2 — Void contract

A pays B AED 1 million under a contract that is subsequently declared void.

The parties may have to restore what they received.

Example 3 — Unlawful retention

B receives A's property without a valid legal basis.

B may be required to return it or, where appropriate, its equivalent/value.

3. Current UAE Law: Unjust Enrichment

Article 274

Article 274 of the current Civil Transactions Law provides that:

no person may take another person's property without a lawful ground;

if property is taken without lawful ground, it must be returned, together with applicable benefits and accretions;

where property is acquired without an acquisitive juridical act, it must be returned if it still exists; and

if it no longer exists, its equivalent or value may have to be restored, subject to the law. (UAE Legislation)

This is the statutory foundation for a broad category of restitutionary claims.

4. Receipt of the Undue Payment

Article 275

Article 275 specifically addresses a person who receives something by way of performance when it was not actually due.

The recipient must make restitution:

in kind if the thing still exists; or

by returning its equivalent/value where it no longer exists, subject to applicable legal rules. (UAE Legislation)

This is particularly relevant to:

mistaken bank transfers;

duplicate payments;

overpayments;

payments after obligations have already been discharged;

payments made under a mistaken understanding of liability;

payments made to the wrong person.

5. Restitution After Contract Nullity

Article 192 provides another important restitutionary mechanism.

Where a contract is annulled or void, the parties are restored to the position they occupied before the contract was concluded.

If restoration is impossible, compensation may be awarded. (UAE Legislation)

Therefore, there are two related but distinct routes:

Route A — Contractual nullity

Void/annulled contract → restoration

Route B — Unjust enrichment/undue receipt

No lawful basis for retention → repayment/restitution

The correct legal basis should be identified before bringing the claim.

6. Restitution Is Not the Same as Damages

This distinction is fundamental.

Restitution

Focuses on:

What benefit did the defendant receive that should be returned?

Damages

Focus on:

What loss did the claimant suffer because of a legally wrongful act?

For example:

A accidentally pays B AED 500,000.

If B has no entitlement to the money:

AED 500,000 → restitution

But if A also suffers a separate legally compensable loss:

additional loss → damages, if the requirements for civil liability are established.

A restitution claim therefore does not automatically establish every possible damages claim.

7. Essential Elements of a UAE Restitution Claim

A practical restitution claim normally requires establishing several matters.

1. Enrichment

The defendant obtained a benefit.

Examples:

money;

property;

use of property;

financial advantage;

discharge of a debt.

2. Corresponding impoverishment or loss

The claimant lost or transferred something of value.

3. Absence of sufficient legal basis

The defendant has no valid legal ground for retaining the benefit.

4. Causal connection

The defendant's enrichment must be connected with the claimant's transfer/loss.

5. Appropriate remedy

The court must determine whether the benefit should be returned:

in kind;

by equivalent property;

by monetary value; or

through another appropriate remedy.

The exact elements can differ depending upon whether the claim is based on unjust enrichment, undue payment, nullity, termination, mistake, or another statutory basis.

8. Case Law 1 — DAMAC Park Towers Company Limited v Youssef Issa Ward [2015] DIFC CA 006

This is an important DIFC Court of Appeal authority concerning restitution and unjust enrichment.

The Court explained that unjust enrichment involved two fundamental questions:

whether the defendant had been enriched; and

whether that enrichment was affected by an unjust factor.

Although DAMAC had received the claimant's payments, the court concluded that there was no unjust factor because the payments were voluntarily made pursuant to the reservation agreement and DAMAC was legally entitled to receive them. Therefore, restitution was unavailable on that basis. (DIFC Courts)

Principle

Enrichment alone is not enough. There must be a legal basis making restitution appropriate.

Importance for UAE law

It provides an excellent analytical distinction between:

money received

and

money wrongfully retained.

Note: DIFC law applied in this case. It should not be presented as a Federal Supreme Court precedent under mainland UAE law.

9. Case Law 2 — Youssef Issa Ward v DAMAC Park Towers Company Limited [2014] DIFC CFI 001

The first-instance court reached a different conclusion.

DAMAC had terminated the reservation agreement, and the court found that the termination was wrongful. It ordered DAMAC to return AED 2,626,335 under the applicable restitution provisions. (DIFC Courts)

The DIFC Contract Law provision considered by the court provided that, following qualifying termination, either party could claim restitution of what it supplied, subject to concurrent restitution of what it had received.

Principle

Restitution following termination is linked to the legal basis for termination.

The subsequent Court of Appeal judgment is particularly important because it reconsidered that conclusion and held that restitution was not available on the facts.

Lesson

A repayment action should clearly identify:

why the contract ended;

who was legally entitled to terminate;

what was supplied;

what was received; and

which statutory restitution provision applies.

10. Case Law 3 — Dagny v Dag & Company International Limited [2011] DIFC CFI 007

This case involved a claim concerning an alleged mistaken payment.

The court analysed restitution through the framework of:

whether there was a mistake;

whether the mistake caused the payment;

whether the recipient had a legal right to receive the money; and

whether the recipient had changed position in good faith.

The court recognised the relevance of the change-of-position defence where an innocent recipient had received money in good faith and subsequently changed their position so that repayment would itself cause injustice. (DIFC Courts)

Principle

A mistaken payment does not necessarily mean that the recipient must always repay every amount.

The circumstances of the recipient's conduct and subsequent change of position can matter.

Importance

This is highly relevant to:

mistaken bank transfers;

salary overpayments;

duplicate payments;

erroneous bonuses;

accounting mistakes.

11. Case Law 4 — Dag & Company International Limited v Dagny [2013] DIFC CA 001

The Court of Appeal considered the restitutionary principles arising from the earlier proceedings.

It recognised the relevance of the change-of-position defence where an innocent recipient had acted in good faith and altered their position in circumstances where requiring full repayment could itself be unjust. (DIFC Courts)

Principle

Restitution must balance the claimant's right to recover against the legal protection available to an innocent recipient whose position has materially changed.

Importance

The case demonstrates that repayment actions are not always mechanically determined by the simple fact that:

“Money was paid incorrectly.”

The court must examine the circumstances surrounding receipt and retention.

12. Case Law 5 — Basin Supply Corporation v Rouge LLC & Claude Barret [2018] DIFC CFI 057

This case concerned a loan and alternative restitutionary arguments.

The claimant argued that if the loan arrangement were found invalid, restitution could arise through unjust enrichment.

The court referred to Article 48 of the DIFC Damages and Remedies Law and the principle that unjust enrichment involves both:

enrichment of the defendant; and

an unjust factor affecting that enrichment. (DIFC Courts)

The claimant identified possible unjust factors including:

mistake;

total failure of consideration; and

payment pursuant to a void contract.

Principle

Where a contractual basis fails, the claimant may need to identify the specific restitutionary basis for recovery rather than simply asserting that the defendant received money.

Importance

This case is especially useful in:

failed loans;

invalid contracts;

failed consideration;

mistaken payments;

restitutionary pleading.

13. Case Law 6 — Larmag Holding B.V. v First Abu Dhabi Bank PJSC & Others [2019] DIFC CFI 054

This is particularly relevant because the DIFC Court considered restitutionary claims under Articles 318 and 319 of the former UAE Civil Transactions Law.

The claimant sought recovery concerning a coupon payment.

The court observed that the relevant UAE Civil Code provisions addressed property transferred without lawful cause and property obtained without an appropriate juridical disposition.

However, the court found that the particular claimant did not possess the necessary title or immediate right to possession to maintain the restitutionary claim concerning that coupon. (DIFC Courts)

Principle

A claimant must establish an appropriate proprietary or legal entitlement to the benefit for which restitution is sought.

Importance for mainland UAE analysis

The old Articles 318–319 are important historically because they formed the basis of UAE unjust-enrichment doctrine before the 2025 Civil Transactions Law.

The current law has reorganised the subject in Articles 274–275. (UAE Legislation)

14. Case Law 7 — Mahesh Srichand Tourani v Dusty Tourani & Duzty LLC [2018] DIFC CFI

The claimant sought repayment of approximately AED 14.947 million and pleaded unjust enrichment.

The court examined whether the money was:

a gift;

a loan; or

an unjustified enrichment.

The court emphasised the claimant's burden of proving the legal basis of the payment and ultimately found that the unjust-enrichment argument was not established on the facts. (DIFC Courts)

Principle

The person seeking repayment must prove the legal and factual basis for restitution.

Simply proving:

“I transferred money to the defendant”

does not automatically establish:

“The defendant must repay me.”

The claimant must explain why the defendant has no lawful entitlement to retain it.

15. Case Law 8 — Roberto's Club LLC & Emain Kadrie v Paolo Roberto Rella [2013] DIFC CFI 019

The case included claims for repayment of housing-related amounts and other benefits.

The court considered whether particular payments constituted unjust enrichment. It accepted that some expenses could properly be recoverable where the contractual/legal basis required repayment after termination, while rejecting other claims where the necessary unjust enrichment requirements were not established. (DIFC Courts)

Principle

Restitutionary analysis must be performed payment by payment and benefit by benefit.

A claimant should not combine unrelated payments into a single undifferentiated restitution claim.

16. Case Law 9 — Karthi Keyan Venkataramana v Ahmed Mohammad Abdul Rahman Ali [2025] DIFC CFI 110

The claimant pursued a loan repayment claim and alternatively pleaded unjust enrichment.

The DIFC Court observed that where a contract governs the parties' relationship and expressly creates repayment obligations, it can be difficult to rely on unjust enrichment as an alternative route for the same subject matter. The court found that the contractual loan obligations themselves governed the relationship. (DIFC Courts)

Principle

Where a valid contract governs the parties' rights, a restitutionary claim should not ordinarily be used simply to bypass the contractual allocation of rights and obligations.

Importance

This distinction is critical:

Valid contract → contractual repayment claim

whereas:

No valid legal basis → restitution/unjust enrichment may become relevant.

17. Case Law 10 — Ohene, Ocarina & Omeri v Ornet & Orrick [2026] DIFC CFI 111/2025

This recent DIFC case involved a claim seeking restitutionary relief concerning shares.

The claimants argued that they had a beneficial entitlement to shares and sought a proprietary restitutionary remedy based upon an alleged failure to perform the agreed exchange.

The court considered whether there was a sufficiently arguable basis for a restitutionary/proprietary claim. (DIFC Courts)

Principle

Restitution can potentially involve proprietary remedies, not merely money.

However, the claimant must establish a proper legal basis for asserting an entitlement to the specific property.

18. Case Law Table

Important: These DIFC authorities are useful for understanding restitution within the UAE's broader legal environment, but DIFC is a separate common-law jurisdiction. The current mainland UAE statutory provisions are found in the federal Civil Transactions Law, particularly Articles 192 and 274–275. (UAE Legislation)

19. Main Types of Repayment Actions

A. Repayment of Undue Payment

This is the classic:

“I paid you something that I did not owe.”

Examples:

duplicate invoice payment;

mistaken bank transfer;

overpayment;

payment after debt was already discharged.

Article 275 directly addresses this category. (UAE Legislation)

B. Repayment After Contract Nullity

A contract is declared void.

The parties must generally return what they received.

Article 192 → restoration to pre-contractual position. (UAE Legislation)

C. Repayment After Annulment

A voidable contract is annulled.

The parties may then have to restore benefits already transferred.

D. Repayment Following Termination

Where the applicable law provides restitution following lawful termination, a party may recover what it supplied subject to the corresponding restitution obligations.

This is particularly developed in DIFC contract jurisprudence, including Ward v DAMAC. (DIFC Courts)

E. Repayment Based on Unjust Enrichment

A person receives a benefit without a sufficient legal basis.

Article 274 of the current Civil Transactions Law provides the federal statutory foundation. (UAE Legislation)

20. Money Received by Mistake

Consider:

A owes B:

AED 50,000

A's accountant accidentally pays:

AED 80,000

The excess is:

AED 30,000

B has a valid legal basis for:

AED 50,000

but potentially no basis for:

AED 30,000

The repayment action therefore concerns the AED 30,000 excess.

Article 275 is directly relevant because it concerns receipt by performance of something that was not due. (UAE Legislation)

21. Duplicate Payment

Suppose an invoice is:

AED 100,000

The buyer pays:

AED 100,000 on Monday; and

AED 100,000 again on Tuesday.

The second payment is potentially an undue payment.

The claimant should prove:

the original debt;

first payment;

second payment;

absence of a second debt;

recipient;

amount claimed.

This is generally much simpler than a complicated unjust-enrichment claim because the factual basis of the repayment is identifiable.

22. Salary Overpayment

Suppose an employer accidentally pays:

AED 30,000

instead of:

AED 10,000.

The employer may seek repayment of the excess, but the legal analysis can become more complicated if:

the employee reasonably believed the payment was correct;

the employee has already spent it;

the employer delayed for a long period before demanding repayment;

employment legislation affects the deduction/recovery mechanism;

the employee disputes the calculation.

The principles of undue receipt and applicable employment law should therefore be analysed together.

23. Repayment Where the Legal Basis Fails

A common situation is:

Payment was made because both parties believed a legal obligation existed, but the obligation never actually existed.

For example:

A pays B AED 500,000 believing that A owes B under a contract.

The court later determines:

The contract was void from the beginning.

The payment may then require restitution.

The analysis becomes:

No valid contract → no contractual basis for retaining payment → restitutionary consequences

subject to the applicable statutory rules.

24. Restitution in Kind

Article 274 recognises return of the property itself where it remains in existence. (UAE Legislation)

Example:

A gives B a specific machine without a lawful basis.

If the machine remains identifiable:

B → returns machine

rather than:

B → automatically pays its original price.

This protects the proprietary nature of the claimant's entitlement.

25. Equivalent or Value

If the property no longer exists, Article 274 contemplates restoration of its equivalent or value, subject to applicable law. (UAE Legislation)

Example:

A transfers 100 units of a particular commodity.

The commodity has been consumed.

The court may need to consider:

equivalent goods; or

monetary value.

The exact valuation date can depend upon the nature of the claim and applicable legal rules.

26. Benefits and Accretions

Article 274 is important because it does not simply speak of returning the principal property.

It also refers to benefits and accretions associated with property taken without lawful ground. (UAE Legislation)

Therefore, a restitution claim may potentially involve:

principal property;

fruits;

income;

benefits;

increases in value;

other legally recognised accretions.

The exact extent depends upon the applicable circumstances and the claimant's legal entitlement.

27. Restitution and Change of Position

The change-of-position issue is especially important in mistaken-payment cases.

Suppose:

A mistakenly pays B AED 500,000.

B genuinely believes the money belongs to B.

B spends the money irreversibly in good faith.

A discovers the mistake six months later.

A repayment action may not be mechanically decided simply by proving the transfer.

The court may need to consider whether the recipient's good-faith change of position affects the restitutionary claim.

The DIFC authorities Dagny v Dag and Dag v Dagny provide important illustrations of this principle. (DIFC Courts)

28. Restitution and Valid Contracts

A restitution claim should not normally be used to rewrite a valid contract.

Example:

A contracts to pay B:

AED 1 million

for consulting services.

B performs the services.

A later says:

“I want my AED 1 million back because B became richer.”

That is not automatically unjust enrichment.

B's enrichment has a contractual basis.

This is why Venkataramana v Ali is useful: where a contract governs the parties' relationship, a restitutionary claim may not provide an alternative route around the contractual terms. (DIFC Courts)

29. Restitution and Failure of Consideration

Another important situation is total failure of consideration.

Example:

A pays B:

AED 2 million

for delivery of a particular asset.

B never delivers anything.

The claimant may have:

contractual remedies;

termination rights;

repayment rights;

restitutionary arguments.

The legal classification matters.

If a valid contract governs the transaction, contractual remedies may be primary.

If the contractual basis itself fails, restitution may become particularly important.

30. Restitution and Void Contracts

The strongest relationship is:

Contract

↓

Fundamental defect

↓

Nullity

↓

Article 192

↓

Restoration

The current law therefore directly connects nullity with restitutionary consequences. (UAE Legislation)

31. Restitution and Partial Nullity

If only part of a contract is invalid, complete repayment may not be appropriate.

The current Civil Transactions Law recognises the possibility that an invalid part may be severed while the remainder survives, depending upon the nature of the transaction.

Therefore:

Invalid clause ≠ automatically invalid entire transaction.

This is important when calculating the repayment amount.

32. Restitution and Third Parties

A repayment action can become complex when money or property passes through several people.

Example:

A → B → C → D

If A's payment was legally ineffective, the court may have to determine:

who received the benefit;

who currently holds it;

whether the benefit was transferred;

whether a third party acted in good faith;

whether proprietary rights arose;

whether the third party is protected by law.

Restitution is therefore sometimes a tracing exercise, not simply a debt claim.

The Larmag case illustrates the importance of identifying the claimant's actual entitlement to the property involved. (DIFC Courts)

33. Restitutionary Claim Versus Debt Claim

These are not identical.

Debt claim

The defendant is contractually obligated to pay a specified amount.

Restitution claim

The defendant must return a benefit because the legal basis for retaining it is absent or has failed.

For example:

Valid loan:
Repayment = debt claim.

Void loan agreement:
Recovery may require restitution/unjust-enrichment analysis.

The Basin Supply case illustrates this distinction. (DIFC Courts)

34. Burden of Proof

The claimant should normally prove the facts necessary to establish the particular restitutionary basis.

Depending on the claim, this can include:

payment;

amount;

recipient;

mistake;

absence of debt;

invalidity;

termination;

enrichment;

lack of lawful ground;

ownership/title;

failure of consideration.

The Tourani case demonstrates the importance of proving the factual and legal basis rather than merely alleging that money should be returned. (DIFC Courts)

35. Evidence in Repayment Actions

Useful evidence includes:

Financial records

bank statements;

transfer receipts;

invoices;

accounting ledgers;

payment confirmations.

Contractual records

contracts;

amendments;

termination notices;

settlement agreements.

Communications

emails;

WhatsApp messages;

letters;

payment instructions.

Legal records

judgments;

nullity decisions;

cancellation orders;

enforcement records.

Expert evidence

May be necessary for:

complicated accounts;

construction payments;

corporate transactions;

valuation;

cryptocurrency;

large multi-party transfers.

36. Practical Example: Mistaken Bank Transfer

A company accidentally transfers:

AED 750,000

to B.

The actual invoice was:

AED 75,000.

The company discovers the mistake.

Claim

The company may seek:

AED 675,000

as undue payment.

Evidence

It should provide:

invoice;

bank statement;

payment instruction;

accounting records;

correspondence with B;

demand for repayment.

Legal basis

The current Article 275 concerning receipt of the undue is directly relevant. (UAE Legislation)

37. Practical Example: Void Contract

A pays B:

AED 2 million

for a transaction later declared void.

B received:

AED 2 million

A seeks:

AED 2 million restitution.

If B also received property from A, B may have to return it.

The objective is:

Mutual restoration, not contractual profit.

Article 192 provides the current statutory basis for restoration after nullity. (UAE Legislation)

38. Practical Example: Property

A transfers a specific asset to B without lawful ground.

If the asset still exists:

Return asset.

If it has been destroyed:

Consider equivalent/value.

If it generated benefits:

Consider applicable benefits/accretions.

This follows the structure of Article 274. (UAE Legislation)

39. Practical Example: Payment Under a Valid Contract

A pays B:

AED 1 million

under a valid contract.

B performs the agreed obligations.

A later demands:

“Return the AED 1 million because you were enriched.”

The claim will generally fail merely because B benefited.

Why?

Because B's enrichment has a lawful contractual basis.

This is the central lesson of DAMAC v Ward: enrichment must be connected to an unjust factor or other recognised restitutionary basis. (DIFC Courts)

40. Restitution After Settlement

A settlement can itself create a new legal basis for payment.

Therefore, after settlement:

“I want my settlement payment back”

does not automatically constitute restitution.

The claimant may need to establish:

invalid settlement;

fraud;

mistake;

non-performance;

rescission;

lack of authority;

another recognised legal ground.

Otherwise, the settlement itself may be the legal basis for retaining the money.

41. Repayment Demand Before Litigation

A practical claimant should normally send a clear demand identifying:

payment date;

amount;

reason payment was not due;

legal basis for repayment;

evidence;

deadline for repayment;

consequences of non-payment.

For example:

“The payment of AED X was made in error and was not legally due. You are requested to return AED X within the specified period.”

The demand creates a clear documentary record.

42. Restitution and Interest

Interest should be analysed separately.

A claimant may seek interest from:

date of demand;

date of default;

date of judgment; or

another legally relevant date.

But restitution of principal and interest are conceptually distinct.

The claimant should therefore plead and prove the legal basis for the interest claim rather than assuming it automatically follows from restitution.

43. Restitution and Limitation

A repayment claim can be subject to limitation rules.

The limitation period may depend on the legal character of the claim:

contractual;

unjust enrichment;

undue payment;

property;

nullity;

damages.

Therefore, the claimant should identify the legal cause of action before calculating limitation.

This is particularly important because calling every repayment claim “unjust enrichment” does not necessarily produce the same limitation consequences as a contractual debt claim.

44. Difference Between Main Restitutionary Actions

45. Important Legal Principle: No Double Recovery

A claimant should not recover the same amount twice.

For example:

A claims:

AED 500,000 contractual debt

and simultaneously:

AED 500,000 unjust enrichment

If the court awards the contractual debt, the claimant cannot ordinarily obtain another AED 500,000 for the same underlying benefit.

Restitution is a mechanism for restoring the claimant's position, not multiplying recovery.

46. Restitution and Counterclaims

Repayment disputes often involve counterclaims.

Example:

A says:

“Return AED 1 million.”

B responds:

“I provided AED 600,000 worth of services.”

The court may have to conduct a complete accounting.

This is especially important where:

a contract was partially performed;

the transaction was partially invalid;

services were supplied;

property was transferred;

payments were made in installments.

47. Relationship With the Current UAE Civil Transactions Law

The current statutory architecture can be remembered as follows:

Article 192

Nullity/annulment → restoration.

Article 193

Partial invalidity/conversion.

Article 274

Unjust enrichment → return property/benefits.

Article 275

Undue receipt → restitution. (UAE Legislation)

Together, these provisions provide a coherent framework for repayment following defective or unjustified transfers.

48. Examination-Oriented Rule

A useful formula is:

Benefit received + no sufficient legal basis + corresponding loss/transfer + causal connection = potential restitution claim.

For an undue payment:

Payment made + payment not legally due = repayment claim, subject to applicable defences and statutory requirements.

For nullity:

Void contract + benefits transferred = restoration under the statutory nullity rules.

49. Key Case-Law Principles

1. DAMAC v Ward

Enrichment alone is insufficient; an unjust factor is important. (DIFC Courts)

2. Ward v DAMAC

Restitution after termination depends on the legal basis of termination. (DIFC Courts)

3. Dagny v Dag

Mistaken-payment restitution may involve mistake, causation, entitlement and change of position. (DIFC Courts)

4. Dag v Dagny

Good-faith change of position may limit repayment. (DIFC Courts)

5. Basin Supply

A claimant should identify the specific unjust factor supporting restitution. (DIFC Courts)

6. Larmag

The claimant must establish an appropriate legal/proprietary entitlement to the property for which restitution is sought. (DIFC Courts)

7. Tourani

The claimant bears the burden of establishing the legal basis for repayment. (DIFC Courts)

8. Venkataramana

Where a valid contract governs the relationship, unjust enrichment should not ordinarily circumvent the contractual framework. (DIFC Courts)

50. Conclusion

Restitution claims and repayment actions under UAE civil law are designed to prevent a person from retaining money, property or another benefit when there is no sufficient legal justification for doing so.

The current UAE Civil Transactions Law provides an especially clear statutory structure:

Article 192 — restoration following nullity or annulment;

Article 274 — unjust enrichment;

Article 275 — receipt of undue payment. (UAE Legislation)

The central principle is:

A person who has received a benefit without a sufficient legal basis may be required to restore that benefit, its equivalent, or its value, subject to the applicable statutory conditions and defences.

But a successful repayment claim requires more than proving that money changed hands. The claimant should establish why the payment was not due, why the recipient has no sufficient legal basis to retain it, what benefit was received, and what precise restitutionary remedy is appropriate.

Quick Revision

Restitution = Return of unjustified benefit

Undue payment = Return of payment that was not legally due

Nullity = Restore the pre-contractual position

Unjust enrichment = Benefit without sufficient lawful ground

Valid contract = Contractual rights normally govern

Mistaken payment = Change of position may be relevant

Restitution ≠ automatic damages

Restitution ≠ automatic contractual profit

No double recovery.

The strongest statutory starting points under the current UAE law are therefore Articles 192, 274 and 275, while the cited DIFC cases provide useful judicial analysis of repayment, unjust enrichment, mistaken payments and restitution but must be distinguished from mainland UAE federal precedent. (UAE Legislation)
