Civil Law and UAE Restitutionary Principles Expansion

1. Introduction

Restitution is the legal process by which a person is required to restore a benefit, payment, property, or value that they have received without sufficient legal justification, particularly after a contract is rescinded, terminated, avoided, or found ineffective.

In UAE civil law, restitution is connected with several broader principles:

restoration after rescission;

prevention of unjust enrichment;

repayment of money paid by mistake;

reversal of benefits under an ineffective transaction;

return of property or its monetary equivalent;

restitution following misrepresentation;

reciprocal restoration after termination;

recovery where consideration has failed;

protection against retaining benefits after the legal basis for retention disappears.

The current UAE framework must be read in light of the Federal Decree by Law No. 25 of 2025 promulgating the Civil Transactions Law, which came into force on 1 June 2026 and replaced the former 1985 Civil Transactions Law. The new Law expressly regulates contractual dissolution and mutual rescission. (UAE Legislation)

A major distinction should nevertheless be maintained between mainland UAE law and DIFC law. Several of the leading published restitution decisions discussed below are DIFC Courts decisions and therefore are not binding mainland UAE precedents. They are particularly useful for understanding restitutionary reasoning in the UAE legal environment.

2. Meaning of Restitutionary Principles

Restitutionary principles seek to answer a different question from ordinary damages.

Damages ask:

What loss has the claimant suffered because of the defendant's breach or wrongful act?

Restitution asks:

What benefit has the defendant received that should be restored?

For example:

A pays AED 1 million to B for a property. The contract is lawfully rescinded before the property is transferred.

The principal restitutionary question is not necessarily whether A lost a future profit of AED 300,000. It is whether B should return the AED 1 million already received.

Thus:

Restitution = restoration of an unjustified benefit

rather than simply:

Restitution = compensation for loss.

3. Expansion of Restitution Under UAE Civil Law

Restitution can arise through several different legal routes.

4. Current UAE Contractual Framework

The 2025 Civil Transactions Law provides an important statutory foundation for restitutionary analysis.

Article 232 — Binding contracts

A valid and binding contract cannot ordinarily be revoked, modified, or rescinded except through:

mutual consent;

litigation; or

a statutory provision permitting it. (UAE Legislation)

This establishes an important starting point:

Restitution normally follows a legally recognized mechanism for undoing or reversing the contractual relationship.

5. Mutual Rescission and Restoration

Article 233 recognizes mutual rescission (Iqala).

The parties may mutually agree to rescind their contract after conclusion.

The new Law specifically provides that:

mutual rescission must satisfy the general requirements of a contract;

partial rescission is possible;

complete rescission requires the possibility of returning the parties to their previous position;

between the contracting parties it has the effect of rescission;

in relation to third parties, it constitutes a new contract. (UAE Legislation)

This is particularly important for restitution.

Example

A sells machinery to B for AED 500,000.

B pays the price and A delivers the machinery.

Later both agree to rescind.

A should ordinarily return the AED 500,000 and B should return the machinery.

This is reciprocal restitution.

6. Restitution and Judicial Rescission

Under Article 234, in a bilateral contract, failure to perform an obligation when due may permit the other party, after notice, to seek performance or rescission.

The court may:

order performance;

grant a grace period;

refuse rescission where the breach is minor;

take account of subsequent performance; and

award compensation where justified. (UAE Legislation)

Therefore, restitution cannot automatically be claimed merely because one party alleges breach.

There must first be a legal basis for rescission or another restitutionary obligation.

7. Automatic Rescission and Restitution

Article 235 permits the parties to agree that the contract will be automatically rescinded upon failure to perform specified obligations, without requiring a judicial judgment. (UAE Legislation)

However, the existence of an automatic-rescission clause does not mean that every question concerning repayment disappears.

A court may still have to determine:

whether the triggering breach occurred;

whether the clause was properly activated;

what payments were made;

whether property was transferred;

whether forfeiture is legally effective;

whether third-party rights exist;

whether additional compensation is available.

Thus:

Termination and restitution are related but analytically distinct questions.

8. Reciprocal Restitution

One of the most important restitutionary principles is reciprocity.

Where both parties have performed, reversal normally requires consideration of both sides' performances.

Formula

Party A's performance → returned to A

Party B's performance → returned to B

For example:

buyer returns goods;

seller returns purchase price.

Where physical restoration is impossible, monetary valuation may become necessary.

This principle is expressly illustrated by the former DIFC Contract Law's restitution provision considered in several DIFC cases: restitution could involve return of what was supplied, with a monetary allowance where restitution in kind was impossible or inappropriate. (DIFC Courts)

9. Restitution in Kind

The preferred form of restitution is often restitution in kind.

Examples:

return of machinery;

return of documents;

return of shares;

return of goods;

restoration of possession of property.

The objective is to reverse the enrichment as directly as possible.

Example

A transfers 1,000 units of equipment to B under a contract that is subsequently rescinded.

If the equipment remains identifiable and returnable, physical return is generally conceptually preferable to calculating an artificial damages figure.

10. Monetary Restitution

Sometimes physical restoration is impossible.

For example:

goods have been consumed;

services have already been performed;

property has been altered;

money has been transferred through several transactions;

digital assets cannot practically be returned;

the benefit has been incorporated into another asset.

In such circumstances, restitution may require a monetary equivalent.

This distinction becomes increasingly important in:

construction;

professional services;

digital transactions;

software licensing;

cryptocurrencies;

tokenized assets;

platform services.

11. Restitution for Services

Services present a special problem.

Suppose:

A performs six months of consulting services for B.

The contract is later rescinded.

The consultant cannot physically return the six months of services.

Therefore, the court may have to determine the value of the benefit actually received.

The important question becomes:

What benefit did the recipient actually obtain, and what amount represents restoration of that benefit?

This is different from asking what profit the service provider expected to earn.

12. Restitution and Unjust Enrichment

Restitution frequently overlaps with unjust enrichment, but they should not be treated as identical.

Restitution after rescission

The legal basis may be:

The contract has been legally undone, therefore prior performances should be reversed.

Unjust enrichment

The reasoning is:

The defendant has obtained a benefit at the claimant's expense without sufficient legal justification.

The distinction is important because a person may be enriched without being unjustly enriched.

The DIFC Court of Appeal expressly emphasized this in DAMAC Park Towers Company Limited v Youssef Issa Ward [2015] DIFC CA 006. The court stated that unjust enrichment requires enrichment together with an unjust factor; enrichment alone was insufficient. (DIFC Courts)

13. Case Law 1 — DAMAC Park Towers v Ward

DAMAC Park Towers Company Limited v Youssef Issa Ward [2015] DIFC CA 006

This is one of the most important UAE restitutionary authorities.

The claimant sought return of approximately AED 2.626 million paid under a property reservation arrangement.

The Court of Appeal held that restitution was not automatically available merely because the defendant had been enriched.

The court emphasized:

there must be enrichment;

there must be an unjust factor;

the claimant must have a proper legal basis for restitution;

a party cannot manufacture restitution by wrongfully terminating a contract.

The court also rejected an interpretation that would allow a party in breach to obtain restitution simply because the contract had been terminated. (DIFC Courts)

Principle

Enrichment + unjust factor + proper legal basis are central to restitutionary recovery.

14. Case Law 2 — Amit Dattani v DAMAC

Amit Dattani & Others v DAMAC Park Towers Company Limited [2012] DIFC CFI 034

The case concerned property purchasers and terminated sale arrangements.

The Court of First Instance ordered repayment of amounts paid by the purchasers following valid termination of the relevant agreements.

The case illustrates reciprocal restitution following termination.

The underlying reasoning demonstrates that where a contract is lawfully terminated and the legal framework provides restitution, sums previously supplied may have to be returned. (DIFC Courts)

The subsequent appellate proceedings confirmed the repayment order in relation to the apartment transaction. (DIFC Courts)

Principle

Lawful termination can create a restitutionary consequence requiring return of contractual payments.

15. Case Law 3 — Youssef Issa Ward v DAMAC

Youssef Issa Ward v DAMAC Park Towers Company Limited [2014] DIFC CFI 001

The first-instance court found that DAMAC had wrongfully terminated the reservation arrangement and ordered repayment of AED 2,626,335.

The court treated the retention of the money as unjust enrichment and relied upon the then-applicable DIFC restitution provisions. (DIFC Courts)

However, the decision must be read together with the subsequent Court of Appeal decision in DAMAC v Ward, which reversed the restitutionary result.

This pair of decisions is particularly valuable for examination purposes because it demonstrates that:

A first-instance restitution order does not necessarily establish the final legal rule.

The Court of Appeal's reasoning in 2015 is the more important authority on the legal requirements for restitution in that dispute. (DIFC Courts)

16. Case Law 4 — Dagny v Dag

Dagny v Dag & Company International Limited [2011] DIFC CFI 007

This case involved an alleged mistaken payment and a claim for restitution.

The DIFC Court considered:

mistake;

causation of the payment;

entitlement to receive the money;

unjust enrichment;

and change of position.

The court relied on the principle that an innocent recipient who has, in good faith, changed position so that requiring repayment would be unjust may have a defence to restitution. (DIFC Courts)

Principle

Change of position can limit or defeat restitution where the recipient acted innocently and in good faith.

17. Case Law 5 — Dag & Company v Dagny

Dag & Company International Limited v Dagny [2013] DIFC CA 001

The Court of Appeal examined the alleged overpayment and the change-of-position defence.

The court emphasized that merely spending money does not automatically establish a defence.

The relevant question is whether the recipient's position changed in circumstances making repayment unjust.

The case therefore demonstrates that:

Change of position is fact-sensitive.

It cannot simply be asserted:

“I spent the money, therefore I do not have to repay it.”

The surrounding circumstances, good faith, knowledge of the mistake, and nature of the expenditure matter. (DIFC Courts)

18. Case Law 6 — Basin Supply Corporation v Rouge

Basin Supply Corporation v Rouge LLC & Claude Barret [2018] DIFC CFI 057

The court considered alternative restitutionary/unjust-enrichment arguments concerning a loan.

The claimant argued, among other things, that restitution could arise because:

payment was made under mistake;

consideration had totally failed;

and the underlying agreement was void or unenforceable.

The court expressly referred to DAMAC v Ward and its formulation that unjust enrichment requires both enrichment and an unjust factor. (DIFC Courts)

Principle

A claimant may need to examine several possible restitutionary bases where the contractual foundation of a transaction fails.

19. Case Law 7 — Salem Dwela v DAMAC

Mr Salem Dwela v DAMAC Park Towers Company Limited [2020] DIFC CA 009

This case is important for the relationship between misrepresentation, rescission and restitutio in integrum.

The Court of Appeal held that the claimant had pleaded an arguable misrepresentation case giving rise to an entitlement to seek rescission and appropriate relief.

The judgment explained that, if the misrepresentation case were established, the court could potentially order rescission accompanied by restitutio in integrum—restoration to the position existing before the transaction. (DIFC Courts)

Principle

Restitution can operate as an incident of rescission following actionable misrepresentation.

20. Case Law 8 — Salem Dwela v DAMAC, First Instance

Salem Dwela v DAMAC Park Towers Company Limited [2018] DIFC CFI 083

The litigation further demonstrates the interaction between:

misrepresentation;

rescission;

damages;

restitution;

limitation.

The case illustrates that restitution may form part of the remedial consequences of rescission rather than simply being treated as a conventional damages claim. (DIFC Courts)

21. Case Law 9 — Hexagon Holdings v DIFC Authority

Hexagon Holdings (Cayman) Limited v DIFC Authority & DIFC Investments LLC [2019] DIFC CFI 013

The claimant sought damages and restitution.

The court rejected the restitutionary claim because the necessary enrichment of the defendants had not been established.

The court stated, in substance, that losses suffered by a claimant do not automatically become restitution merely because another party is involved.

There must be enrichment of the defendant and an appropriate restitutionary basis. (DIFC Courts)

Principle

Claimant's loss is not the same thing as defendant's enrichment.

This is one of the most important distinctions between damages and restitution.

22. Case Law 10 — Dattani Court of Appeal

Amit Dattani & Others v DAMAC Park Towers Company Limited [2014] DIFC CA 007

The appellate proceedings confirmed the restitutionary consequences of the valid termination of the relevant property arrangements, including repayment of amounts paid under the apartment transaction.

The case provides an example of restitution operating as a contractual consequence of lawful termination. (DIFC Courts)

23. Core Restitutionary Principles

The cases collectively demonstrate several important principles.

Principle 1 — Restitution requires a legal foundation

A claimant cannot simply say:

“The defendant has my money, therefore I automatically get it back.”

The claimant must identify the legal basis:

rescission;

termination;

mistake;

failure of consideration;

unjust enrichment;

misrepresentation;

invalidity;

statutory restoration;

or another recognized ground.

Principle 2 — Enrichment alone is insufficient

DAMAC v Ward is particularly important.

The defendant's enrichment must be legally unjustified or affected by an appropriate unjust factor. (DIFC Courts)

Principle 3 — Restitution and damages are different

Suppose A pays B AED 1 million and B wrongfully retains it.

Restitution may require:

AED 1 million returned.

Damages may additionally concern:

consequential loss, lost opportunity, additional expenditure, or other legally recoverable damage.

The two remedies may coexist where the legal requirements are independently satisfied.

Principle 4 — Reciprocal restitution is important

Where A received something from B and B received something from A, reversal generally has to consider both sides of the transaction.

Principle 5 — Restitution may be monetary

Where physical restoration is impossible, a monetary equivalent may be required.

Principle 6 — Change of position can restrict recovery

The Dagny decisions demonstrate the importance of good-faith change of position. (DIFC Courts)

Principle 7 — A claimant's loss is not automatically the defendant's enrichment

Hexagon demonstrates this distinction. (DIFC Courts)

24. Restitution After Contractual Invalidity

Where a contract is legally ineffective, the parties may have received benefits under an arrangement that ultimately lacks the legal foundation for retention.

Possible consequences include:

return of money;

return of property;

restoration of possession;

monetary valuation of consumed benefits;

accounting for profits where legally justified;

adjustment for counter-performance.

The precise remedy depends upon the legal reason for invalidity and the applicable statutory framework.

25. Restitution After Rescission

A useful analytical sequence is:

Valid contract

↓

Ground for rescission

↓

Valid rescission

↓

Contractual relationship is undone or terminated

↓

Determine prior performances

↓

Identify benefits received by each party

↓

Return property/money where possible

↓

Monetary equivalent where physical restoration is impossible

↓

Consider damages separately

This prevents restitution from being confused with compensation.

26. Restitution and Compensation

Example

A pays AED 2 million for property.

Contract is rescinded.

B returns AED 2 million.

That is principally restitution.

If A additionally proves AED 200,000 of recoverable consequential loss caused by the legally actionable conduct, that may raise a separate damages question.

27. Restitution and Unjust Enrichment: Expanded Test

A practical restitutionary analysis can use the following questions:

Question 1 — Was there an enrichment?

Did the defendant receive:

money?

property?

services?

discharge of a debt?

another measurable economic benefit?

Question 2 — At whose expense?

Was the enrichment obtained from the claimant or otherwise connected to the claimant's deprivation?

Question 3 — What is the legal basis?

Why does the defendant have the benefit?

Possible answers:

valid contract;

valid payment;

statutory entitlement;

rescission;

mistake;

invalid contract;

failure of consideration.

Question 4 — Is the retention legally unjustified?

This is particularly important after DAMAC v Ward. (DIFC Courts)

Question 5 — Has the legal basis disappeared?

For example, has the contract been rescinded?

Question 6 — Can the original benefit be returned?

If yes:

restitution in kind.

If no:

monetary restitution may need to be assessed.

Question 7 — Is there a defence?

For example:

change of position;

third-party rights;

contractual allocation of risk;

statutory limitation;

other applicable legal defence.

28. Restitution in Real Estate Transactions

Real-estate disputes are especially significant in UAE practice.

Typical restitution questions include:

purchaser paid instalments;

developer failed to perform;

reservation agreement terminated;

SPA rescinded;

project cancelled;

property was never transferred;

registration never occurred;

purchaser seeks repayment.

The Dattani and Ward/DAMAC cases demonstrate how important the precise contractual basis of termination can be. (DIFC Courts)

A court must distinguish between:

lawful termination by purchaser,

and:

unlawful repudiation or termination by purchaser.

The restitutionary result can be substantially different.

29. Restitution and Third-Party Rights

Restitution becomes more complicated where property has moved to a third party.

For example:

A → B → C

If A and B rescind their contract, C's rights cannot necessarily be ignored.

The new UAE Civil Transactions Law specifically recognizes that mutual rescission has one effect between the original parties but constitutes a new contract as against third parties. (UAE Legislation)

Therefore, restitution is not simply:

“Reverse everything mechanically.”

The court must examine:

third-party acquisition;

registration;

good faith;

proprietary rights;

statutory protections.

30. Restitution in Digital Transactions

The expansion of digital economies creates new restitutionary problems.

Examples include:

erroneous electronic transfers;

mistaken wallet transfers;

failed digital payments;

cryptocurrency transfers;

smart-contract execution;

digital subscriptions;

platform credits;

tokenized assets;

automated payments;

duplicate payments.

The traditional principle remains relevant:

A technological mechanism does not necessarily create substantive entitlement to retain an unjustified benefit.

However, practical restitution may be complicated where:

the recipient cannot be identified;

the asset has changed form;

the digital asset has been transferred to a third party;

the asset has fluctuated dramatically in value;

the transaction is irreversible;

an intermediary has intervened.

31. Restitution and Change of Value

Suppose:

A transfers an asset worth AED 100,000.

Before restitution proceedings, the asset becomes worth AED 180,000.

The court may have to distinguish:

return of the original asset;

return of its value;

profits derived from the asset;

appreciation caused by the recipient;

appreciation caused by market conditions.

This is why restitutionary valuation can become substantially more complex than simple repayment.

32. Restitutionary Damages vs Restitution

These concepts should not automatically be treated as identical.

Restitution

Attempts to restore a benefit.

Restitutionary damages

May refer to monetary relief calculated with reference to the defendant's gain or benefit rather than the claimant's ordinary loss, depending on the applicable legal system and cause of action.

A UAE practitioner should therefore identify the specific statutory and contractual basis rather than assuming that every claim described as “restitutionary damages” is available.

The DIFC Ward litigation illustrates precisely why the legal basis of restitution matters. (DIFC Courts)

33. Restitution and Partial Performance

Suppose a contract involves:

AED 1 million total price;

60% performance by A;

40% performance remaining.

If the contract is rescinded, the court may need to determine:

what was supplied;

what was received;

what remains identifiable;

whether the contract is divisible;

whether partial performance created a benefit;

whether monetary adjustment is required.

The new UAE law's recognition of partial mutual rescission is therefore relevant to sophisticated restitutionary disputes. (UAE Legislation)

34. Restitution and Minor Breach

Article 234 is also significant because rescission may be refused where the unperformed obligation is of minor importance in relation to the contract as a whole. (UAE Legislation)

This means:

A minor breach does not necessarily trigger complete contractual reversal and restitution.

The seriousness of breach is therefore indirectly relevant to restitution.

35. Restitutionary Principles in Construction Contracts

Construction disputes can involve:

advance payments;

mobilisation payments;

incomplete work;

terminated contracts;

defective performance;

materials supplied;

partially completed structures.

If the contract is terminated, the court may need to calculate:

Money paid − value properly received ± other legally recoverable adjustments.

The analysis becomes especially difficult where construction has created a permanent improvement to land.

36. Restitution and Good Faith

Good faith can influence restitutionary disputes, particularly where:

a recipient did not know payment was erroneous;

money was spent innocently;

the recipient changed position;

the claimant delayed seeking repayment;

the recipient reasonably relied on apparent entitlement.

The Dagny cases illustrate the importance of good faith and change of position. (DIFC Courts)

However:

Good faith does not automatically legalize an otherwise unjustified retention.

It is one factor within the relevant legal framework.

37. Restitution and Evidence

A successful restitution claim usually requires evidence showing:

Payment evidence

bank transfers;

receipts;

invoices;

account statements.

Contract evidence

SPA;

reservation agreement;

amendments;

termination notice;

rescission agreement.

Benefit evidence

property delivery;

services performed;

goods delivered;

possession transferred.

Legal-basis evidence

breach;

mistake;

invalidity;

misrepresentation;

rescission;

failure of consideration.

Valuation evidence

market valuation;

expert evidence;

accounting records;

transaction records.

38. Practical Restitution Formula

A useful examination formula is:

Restitutionary entitlement = Benefit received + legal basis for reversal − applicable counter-performance/adjustments − valid defences.

For unjust enrichment:

Enrichment + claimant's corresponding deprivation + unjustifying factor/absence of legal basis + no applicable defence = potential restitution.

For rescission:

Valid rescission + identifiable prior performance + restoration requirement = potential reciprocal restitution.

These are analytical formulas rather than statutory mathematical formulas.

39. Important Case-Law Table

These authorities should be identified as DIFC authorities, not presented as binding judgments of the UAE Federal Supreme Court or mainland Dubai courts. (DIFC Courts)

40. Relationship Between the Major Restitutionary Concepts

A. Rescission

Destroys or reverses the contractual relationship according to the applicable law.

↓

B. Restitution

Returns benefits previously transferred.

↓

C. Unjust enrichment

Prevents unjustified retention of a benefit.

↓

D. Damages

Compensates legally recoverable loss.

These doctrines can overlap, but they should not be collapsed into one remedy.

41. Examination-Oriented Legal Test

When faced with a UAE restitution problem, use this 8-step test:

Step 1 — Identify the transaction

What contract/payment/transfer occurred?

Step 2 — Identify the benefit

What did each party receive?

Step 3 — Identify the legal basis

Was the benefit received under a valid contract?

Step 4 — Identify the reversal event

Was there:

rescission?

termination?

invalidity?

mistake?

failure of consideration?

misrepresentation?

Step 5 — Establish enrichment

What benefit remains with the defendant?

Step 6 — Consider unjustness

Why should the defendant no longer retain it?

Step 7 — Consider defences

Especially:

change of position;

third-party rights;

contractual allocation;

limitation;

other statutory defences.

Step 8 — Calculate remedy

Determine:

return in kind;

repayment;

monetary equivalent;

accounting;

and, separately, any damages.

42. Key Distinction for Exams

A very useful sentence is:

Restitution is primarily concerned with reversing an unjustified benefit, whereas damages are primarily concerned with compensating legally recoverable loss.

Another important sentence is:

The mere fact that one party has been enriched does not automatically establish a restitutionary claim; the claimant must establish the applicable legal basis for reversal.

That principle is particularly strongly illustrated by DAMAC Park Towers v Ward. (DIFC Courts)

43. Effect of the 2025 Civil Transactions Law

For current UAE-law analysis after 1 June 2026, the 2025 Civil Transactions Law should be used as the primary statutory framework rather than mechanically citing provisions of the repealed 1985 Code.

The new Law expressly addresses:

binding contracts;

mutual rescission;

partial rescission;

restoration to the pre-contract position;

judicial rescission;

automatic rescission clauses;

compensation accompanying rescission. (UAE Legislation)

Older cases remain useful for understanding legal reasoning, but their statutory citations must be checked against the current legislation before being treated as statements of present mainland UAE law.

44. Conclusion

UAE restitutionary principles are expanding from a simple “return the money” concept into a broader system of restoration, unjust enrichment, contractual reversal and remedial adjustment.

The major principles are:

Restitution focuses on benefits, while damages focus primarily on loss.

Rescission can create an obligation to reverse previous performance.

Mutual rescission under the current Civil Transactions Law expressly contemplates restoration of the pre-contract position.

Restitution may be in kind or monetary.

Reciprocal restoration is important in bilateral contracts.

Enrichment alone does not necessarily constitute unjust enrichment.

An unjust factor or other legal basis is important in unjust-enrichment claims.

Mistaken payments can generate restitutionary claims, subject to applicable defences.

Good-faith change of position can limit restitution.

A claimant's loss is not automatically the defendant's enrichment.

Misrepresentation may support rescission and restitutio in integrum.

Third-party rights can complicate restoration.

Digital transactions create new valuation and tracing problems without eliminating traditional restitutionary principles.

Current mainland UAE analysis must now be aligned with Federal Decree by Law No. 25 of 2025, effective 1 June 2026. (UAE Legislation)

Quick Revision Formula

Restitution = Identify benefit → identify legal basis for reversal → establish enrichment → determine what must be restored → consider reciprocal performance → consider defences → calculate appropriate restoration.

Most important cases to remember: DAMAC v Ward, Dattani v DAMAC, Dagny v Dag, Dag & Co v Dagny, Basin Supply v Rouge, Salem Dwela v DAMAC, and Hexagon Holdings v DIFCA.
