Civil Law and UAE: Restitution After Contract Nullity

1. Introduction

Restitution after contract nullity refers to the legal process of restoring the parties to the position they occupied before the void contract was made.

Under the current UAE Civil Transactions Law, Federal Decree-Law No. 25 of 2025, the basic rule is now expressly stated in Article 192:

When a contract is annulled or is void, the contracting parties are restored to the position they were in before the contract was concluded. If restoration is impossible, compensation may be awarded.

This principle is often described as restitutio in integrum.

The basic sequence is:

Void contract → No valid contractual effect → Restoration → Return of money/property → Compensation if restoration is impossible

The doctrine is particularly important where a contract involves:

• illegal purpose;
• absence of a required contractual element;
• forged documents;
• lack of authority;
• violation of mandatory law or public order;
• invalid consent;
• lack of capacity;
• unlawful consideration;
• defective subject matter; or
• another fundamental legal defect.

2. Current UAE Legal Framework

The current Civil Transactions Law distinguishes between nullity and annulment/voidability.

Nullity

A fundamentally defective contract is void from the beginning and does not produce the ordinary legal effects of a valid contract.

Annulment

A voidable contract may remain effective until the legally protected party exercises the right of annulment or obtains an appropriate judicial remedy.

The distinction matters because the consequences, limitation rules and possibility of ratification can differ.

Article 192

The central restitution provision states that:

1. where a contract is annulled or void, the parties are restored to their pre-contractual position; and
2. where restoration is impossible, compensation may be awarded. 

This is the primary statutory foundation for restitution following nullity under the current UAE law.

3. What Does “Restoration to the Previous Position” Mean?

Suppose:

• A pays B AED 1 million;
• B transfers property to A;
• the contract is subsequently declared void.

Restoration normally requires:

A → returns property to B

and

B → returns AED 1 million to A.

The objective is not to give either party the benefit of the invalid bargain.

Instead, the objective is to remove the consequences produced by the invalid transaction.

4. Restitution Is Different from Damages

This distinction is extremely important.

Restitution

Asks:

What did each party receive under the invalid transaction?

The answer determines what should be returned.

Damages

Ask:

What additional loss did the claimant suffer because of the legally wrongful conduct?

Therefore:

Restitution ≠ automatic damages.

A party may recover the amount paid under a void contract without automatically recovering:

• anticipated profits;
• speculative profits;
• lost business opportunities;
• consequential losses; or
• moral damages.

Such additional claims require their own legal basis and proof.

5. Restitution Is Not a Reward for the Invalid Contract

A fundamental principle is:

A party should not obtain the economic benefit that the invalid contract itself was supposed to create.

For example, if an investment agreement is declared void because its underlying activity violates mandatory law, the investor may ordinarily seek return of the principal actually transferred.

But the investor cannot automatically claim:

“Because the contract promised 20% profit, I must receive that 20%.”

The promised contractual profit depends upon the validity of the contractual arrangement.

A recent UAE case involving an invalid cryptocurrency investment arrangement illustrates this distinction: the court treated the agreement as absolutely void and confined restitution to restoration of the principal, while a separate claim for profits was not treated as automatically recoverable.

6. Main Forms of Restitution

Restitution can take several forms.

A. Return of Money

The most straightforward example.

If A paid:

AED 500,000

under a void contract, A may seek restoration of that amount.

B. Return of Property

If property was transferred pursuant to the void contract, the property may have to be returned.

Examples:

• land;
• apartment;
• vehicle;
• machinery;
• shares;
• valuable goods.

C. Restoration of Possession

Where a void transaction resulted in possession being transferred, restoration may require the return of possession.

D. Cancellation of Transferred Rights

Where legally possible, the consequences of an invalid transaction may require reversal of rights that were purportedly transferred.

E. Monetary Equivalent

Sometimes returning the original thing is impossible.

For example:

• the goods were consumed;
• property was destroyed;
• the asset cannot be identified;
• the thing has been irreversibly transformed.

In such circumstances, Article 192 allows compensation where restoration is impossible.

7. Mutual Restitution

Restitution generally operates bilaterally.

If:

• A must return the property,

B may also have to:

• return the purchase price.

This prevents unjust enrichment.

A cannot ordinarily say:

“The contract is void, so I want my money back, but I will keep the property.”

The court must consider the entire transaction and the benefits received by both parties.

8. Restitution and Unjust Enrichment

Nullity and unjust enrichment are closely related but should not be confused.

Nullity

The contract itself is legally defective.

Unjust enrichment

One person has obtained a benefit at another's expense without sufficient legal justification.

When a contract is declared void, the legal basis for retaining benefits received under that contract may disappear.

Consequently:

Nullity → removal of contractual basis → restitution

The DIFC courts have expressly analysed restitution through this unjust-enrichment framework in appropriate cases.

9. Case Law 1 — Abu Dhabi Court of Cassation, Commercial Appeal No. 206/2026, Judgment of 14 May 2026

This is a particularly important current UAE authority.

The case concerned a yacht whose ownership documents had been forged. The dispute involved subsequent transfers based upon those documents.

The Abu Dhabi Court of Cassation applied the doctrine of absolute nullity to transactions founded upon the forged documents. The court treated the relevant transactions as void ab initio and considered the consequences of returning the parties to their pre-transaction legal position.

The court relied upon the statutory concept that a void contract:

• is defective in its essential legal foundation;
• produces no legal effect;
• cannot be validated through ratification; and
• may have its nullity raised by an interested party or by the court where legally appropriate. 

Principle

Forgery can produce absolute nullity, and nullity triggers restoration of the pre-contractual position.

Importance

This case is highly relevant to:

• forged sale documents;
• property transfers;
• chain-of-title disputes;
• good-faith purchasers;
• restitution;
• criminal judgments affecting civil proceedings.

10. Case Law 2 — Dubai Court of Cassation, Civil Appeal No. 143 of 2014

This is an important historical UAE authority concerning the consequences of a void contract.

The Dubai Court of Cassation recognised the principle that a genuinely void contract does not create the ordinary contractual obligations associated with a valid contract and that nullity operates retrospectively.

Principle

A contract that is void at its foundation cannot ordinarily be treated as a valid contractual source of rights and obligations.

Restitution significance

Once the transaction is treated as legally ineffective, the court must address what the parties actually transferred under the purported transaction.

This historical authority arose under the former 1985 Civil Transactions Law and should therefore be read together with the current Article 192 framework.

11. Case Law 3 — Dubai Court of Cassation, Case No. 814/2025

This case concerned an investment arrangement involving cryptocurrency-related activity.

The arrangement was challenged as violating mandatory legal requirements/public order.

The court upheld the conclusion that the arrangement was absolutely void. The consequences included restoration of the principal amount rather than enforcement of the contractual profit arrangement. The court also distinguished restitution from a claim for damages, emphasising the need to establish fault, damage and causation for an independent damages claim.

Principle

Where the underlying contract is absolutely void:

Principal paid → potentially recoverable

but:

Expected contractual profit → not automatically recoverable.

Importance

This case provides a very useful examination example of the difference between:

restitution of an existing benefit

and

damages for hypothetical future benefits.

12. Case Law 4 — Globemed Gulf Healthcare Solutions LLC v Oman Insurance Company PSC [2017] DIFC CFI 051

This is a DIFC Court authority involving UAE-law issues and should not be treated as a mainland UAE precedent.

One issue concerned whether the alleged invalidity of a Dubai-incorporated company meant that contracts associated with it were automatically void.

The court considered the distinction between the validity of the company structure and the validity of individual contractual arrangements.

Principle

Invalidity of one legal arrangement does not automatically invalidate every separate transaction connected with it.

Restitution significance

Before ordering restitution, a court must identify:

1. which legal act is actually void;
2. what benefits were transferred under that act; and
3. whether the particular transaction has a sufficient legal basis for restitution.

This prevents an overly broad approach in which every related transaction is automatically unwound.

13. Case Law 5 — Gjurd v Gizella (DIFC) Limited [2016] DIFC SCT 081

This is one of the clearest UAE-based judicial illustrations of restitution following nullity.

The DIFC Small Claims Tribunal found that a contract was void because of a mistake concerning the product purchased.

The court then expressly applied the restitution provisions of the DIFC Contract Law.

The claimant had invested USD 80,000. The court ordered restitution but deducted amounts already received by the claimant from the transaction.

The court rejected a claim for an additional USD 10,000 in lost profits, explaining that traditional restitution generally restores the position that would have existed had the contract never been concluded; the claimant would not have earned those profits in the counterfactual situation where no contract existed.

Principle

Restitution restores the pre-contractual position; it does not ordinarily award hypothetical profits that would have arisen from performing the invalid transaction.

Importance

This is an excellent case for examinations because it clearly separates:

Restitution → restoration

from

Expectation damages → contractual performance benefit.

14. Case Law 6 — DAMAC Park Towers Company Limited v Youssef Issa Ward [2015] DIFC CA 006

This is a major DIFC Court of Appeal authority on restitution.

The first-instance court had ordered repayment of sums paid by the purchaser.

The Court of Appeal reversed that result because the purchaser had not lawfully terminated the contract.

The court explained that restitution under the DIFC framework was connected with lawful termination and unjust enrichment. It emphasised that although DAMAC had received money, there was no unjust factor requiring repayment because the payments had been made voluntarily under a valid contractual arrangement.

Principle

Payment alone does not automatically establish a restitutionary claim.

The court must identify a legal basis for restitution.

Importance

This is particularly useful for distinguishing:

• valid contract + lawful payment;
• valid contract + wrongful termination;
• void contract; and
• unjust enrichment.

15. Case Law 7 — Youssef Issa Ward v DAMAC Park Towers [2014] DIFC CFI 001

The first-instance judgment reached the opposite conclusion from the later Court of Appeal.

The trial court found that DAMAC had wrongfully terminated the agreement and had committed a material breach. It ordered repayment of AED 2,626,335 in restitution.

The case demonstrates an important point:

The legal basis for restitution must be established before the court can determine the amount to be restored.

The Court of Appeal subsequently reversed the restitution order, making this a useful case study in appellate correction of restitutionary reasoning.

16. Case Law 8 — Lendro v Mr Lutis [2020] DIFC SCT 166

This case concerned termination rather than absolute nullity, but it is useful for understanding the mechanics of restitution.

The DIFC court applied Article 90 of the DIFC Contract Law, under which a party terminating a contract may claim restitution of what it supplied, subject to making restitution of what it received.

The claimant had paid a AED 142,000 deposit, and the court ordered its refund after lawful termination.

Principle

Restitution ordinarily operates reciprocally:

Return what you received while recovering what you supplied.

Relevance to UAE civil law

Although it concerns DIFC law and contractual termination rather than mainland federal nullity, it provides a useful comparative illustration of the restitutionary principle.

17. Case Law 9 — Basin Supply Corporation v Rouge LLC & Claude Barret [2018] DIFC CFI 057

This case considered restitution and unjust enrichment where the validity of a loan arrangement was disputed.

The DIFC Court considered Article 48 of the DIFC Damages and Remedies Law, under which restitution could arise where:

• restitution was expressly provided for; or
• one party had been unjustly enriched at another's expense,

subject to the applicable conditions.

Principle

Restitution requires an identifiable legal or restitutionary basis; it is not simply a discretionary mechanism for reversing every unsuccessful transaction.

Importance

It is particularly useful in:

• invalid contracts;
• loans;
• unjust enrichment;
• mistaken payments;
• restitutionary claims.

18. Case Law 10 — Amit Dattani and Others v DAMAC Park Towers [2014] DIFC CA 007

The DIFC Court of Appeal considered Article 90 of the DIFC Contract Law concerning restitution following termination.

The court examined whether payments made under the contractual arrangement could be recovered after termination.

Principle

Restitution must be analysed according to:

• the legal basis of termination;
• what was supplied;
• what was received;
• whether the contract is divisible; and
• the statutory restitution provisions.

This case is useful for understanding the relationship between termination and restitution, although it is not a federal UAE nullity case.

19. Case Law Summary

Important: The first three are mainland UAE authorities. The remaining authorities are DIFC cases, based on the separate DIFC legal framework. They are useful for comparative UAE legal analysis but should not be cited as if they were Federal Supreme Court precedents under the mainland Civil Transactions Law.

20. Restitution After Absolute Nullity

The strongest form of invalidity is absolute nullity.

The conceptual sequence is:

Step 1 — Identify fundamental defect

For example:

• unlawful purpose;
• forged document;
• absent essential element;
• prohibited subject matter;
• mandatory form not satisfied.

Step 2 — Declare nullity

The contract is treated as legally ineffective.

Step 3 — Identify benefits transferred

Determine:

• money paid;
• property transferred;
• goods delivered;
• possession transferred;
• services rendered.

Step 4 — Restore benefits

Each party returns what it received where possible.

Step 5 — Address impossibility

If restoration in kind is impossible, monetary compensation may become necessary.

21. Restitution Where Property Has Been Consumed

Suppose A pays AED 100,000 under a void contract and receives goods.

The goods are consumed before nullity is established.

The court cannot physically return the consumed goods.

The restitution analysis may therefore require consideration of their monetary value and the applicable compensation principles.

The current Article 192 expressly recognises the possibility of compensation where restoration is impossible.

22. Restitution Where Property Has Increased in Value

Suppose a void sale transfers property worth:

AED 2 million

and by the time nullity is established it is worth:

AED 3 million.

The question becomes more complicated than simply saying:

“Return AED 2 million.”

The court may have to consider:

• who legally owned the property;
• possession;
• improvements;
• appreciation;
• income generated;
• expenses;
• good faith;
• third-party rights; and
• the applicable statutory rules.

Therefore, restitution is a transaction-wide accounting exercise, not simply a refund calculation.

23. Restitution and Good-Faith Third Parties

A particularly difficult issue arises where a void transaction is followed by another transaction.

Example:

A → B → C

If the A-B contract is void, what happens to C?

The answer cannot simply be:

“Everything after A-B is automatically void.”

The court must examine:

• nature of the original defect;
• whether the property could legally be transferred;
• registration;
• good faith;
• statutory protection;
• notice;
• fraud;
• public order;
• applicable property rules.

The 2026 Abu Dhabi yacht case illustrates the importance of this issue because forged ownership documents were used in subsequent transfers.

24. Restitution and Criminal Proceedings

Where nullity arises from forgery or fraud, criminal proceedings can become important.

A final criminal judgment may have binding consequences in related civil proceedings concerning matters that the criminal court necessarily and finally determined, subject to the applicable procedural rules.

In the 2026 Abu Dhabi yacht dispute, the Court of Cassation considered the effect of the final criminal conviction concerning forged ownership documents.

Thus:

Forgery → Criminal judgment → Civil consequences → Nullity → Restoration

25. Restitution and Interest

Interest requires separate analysis.

A claimant may argue that merely returning the principal is insufficient because the defendant retained the money for a significant period.

However:

principal restitution ≠ automatic entitlement to every claimed financial consequence.

The court must consider:

• statutory interest rules;
• contractual provisions, if legally relevant;
• date of demand;
• date of judgment;
• nature of the restitutionary claim;
• applicable procedural law.

The legal basis for interest should therefore be separately established.

26. Restitution and Lost Profits

This is a very important examination issue.

Suppose:

A invests AED 1 million under a contract promising:

AED 200,000 profit.

The contract is declared void.

A ordinarily cannot simply say:

“Give me AED 1.2 million because that is what the contract promised.”

Why?

Because the purpose of restitution is generally to put A in the position in which A would have been if the void contract had never existed.

The AED 200,000 was an expected benefit from the invalid contract.

The Gjurd case illustrates this distinction particularly clearly. The court restored the investment after deducting amounts already received but rejected the additional lost-profit claim.

27. Restitution and Compensation

Article 192 expressly recognises compensation where restoration is impossible.

But this should not be misunderstood.

Restitution

Restores what was transferred.

Compensation

Addresses loss where restoration cannot adequately be achieved or where an independent legal basis for damages exists.

Example

A transfers a unique machine under a void contract.

The machine is destroyed.

Physical restitution is impossible.

The court may therefore have to determine the appropriate monetary consequence.

28. Partial Nullity

The current Civil Transactions Law also recognises partial invalidity.

Article 193 provides, in substance, that if only part of the contract is void or voidable, that part alone may be invalid unless it is established that the contract would not have been concluded without that part. It also recognises conversion where the elements of another contract exist.

Therefore:

Invalid clause → remove clause → remainder survives

unless:

Invalid clause is essential → entire contract may fail.

This directly affects restitution.

If only one separable clause is invalid, complete unwinding of the entire transaction may not be necessary.

29. Conversion of Invalid Contracts

Article 193 also permits a potentially invalid contract to be treated as another valid contract where the necessary elements of the alternative contract exist and the statutory requirements are satisfied.

This reflects a contract-preserving approach.

The sequence becomes:

Invalid contract

↓

Can defective part be severed?

↓

If not, can transaction be converted into another valid contract?

↓

If neither is possible → nullity + restitution

This prevents unnecessary destruction of a transaction where the law permits preservation.

30. Nullity Versus Termination

This distinction is essential.

The DAMAC v Ward litigation demonstrates why a court must identify the proper legal basis before awarding restitution.

31. Nullity Versus Annulment

Nullity

The defect is fundamental.

Annulment

The law protects a particular party whose consent, capacity or legal position was defective.

Under the current law, Article 191 provides a general one-year period for exercising the right of annulment, subject to the specific statutory starting points and the special long-stop rules specified there.

Article 192 then addresses the consequences after annulment or nullity.

Thus:

Nullity/annulment → restoration

but the legal route to reach that result can differ.

32. Practical Example: Forged Sale

Suppose:

• A owns a yacht.
• B forges ownership documents.
• B sells the yacht to C.
• C pays AED 2 million.
• The transaction is later established to be based on forgery.

The court may need to determine:

1. Was the original transaction void?
2. Who was the true owner?
3. What was the effect of the forged documents?
4. Was C in good faith?
5. Can the yacht be restored?
6. Who should return the AED 2 million?
7. Were there subsequent transfers?
8. Are there damages in addition to restitution?

The 2026 Abu Dhabi Court of Cassation yacht case illustrates the importance of this chain-of-title analysis.

33. Practical Example: Void Investment Contract

Suppose:

A pays:

AED 500,000

under an investment contract that is subsequently declared void for violating mandatory law.

The court may order:

AED 500,000 → returned to A

But A cannot automatically demand:

AED 150,000 promised profit

because that profit arose from the invalid contractual bargain.

The 2025 Dubai Cassation cryptocurrency-investment case illustrates this distinction.

34. Practical Example: Partial Nullity

Suppose a contract contains:

• valid sale of machinery; and
• one unlawful ancillary clause.

If the unlawful clause can be separated from the rest of the transaction, Article 193 may permit the remainder to survive.

In that situation:

No complete restitution

may be necessary.

Instead:

Invalid clause removed → valid contract continues.

35. Practical Litigation Steps

A restitution claim following nullity should normally establish:

1. Existence of the purported contract

Produce:

• contract;
• invoices;
• correspondence;
• payment records.

2. Legal defect

Identify exactly why the contract is void.

3. Nature of nullity

Determine whether the defect produces:

• absolute nullity;
• voidability;
• partial nullity; or
• another legal consequence.

4. Benefits transferred

Calculate:

• money;
• property;
• goods;
• possession;
• other benefits.

5. Trace the benefits

Identify where the property or money went.

6. Determine whether restoration is possible

If yes:

restore in kind.

If no:

determine monetary equivalent/compensation.

7. Examine third-party rights

Especially where property or registered assets are involved.

8. Separate restitution from damages

Do not combine:

return of benefit

with

compensation for independent loss

without establishing the separate legal basis.

36. Key Principles from the Case Law

The cases collectively demonstrate the following principles:

Principle 1

A void contract does not become valid merely because the parties performed it.

Principle 2

Nullity can require restoration of the pre-contractual position.

Principle 3

Restitution is not the same as damages.

Principle 4

Expected contractual profits are not automatically restitution.

Principle 5

The claimant must establish the legal basis for restitution.

Principle 6

Mutual restitution may be required.

Principle 7

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

Principle 8

Not every associated transaction automatically becomes void.

Principle 9

Partial nullity can preserve the remainder of a contract.

Principle 10

DIFC restitution principles should not be mechanically transferred to mainland UAE cases because DIFC has a separate legal framework.

37. Exam-Oriented Formula

Remember:

Nullity → No valid contractual foundation → Identify benefits → Mutual restitution → Monetary compensation if restoration impossible.

And:

Restitution ≠ expectation damages.

A claimant normally seeks to recover what was transferred, not automatically what the invalid contract promised to produce.

38. Short Revision Table

39. Conclusion

Under the current UAE Civil Transactions Law, restitution is the principal mechanism for reversing the practical consequences of a void or annulled contract.

Article 192 establishes the central rule: the parties should be restored to the position they occupied before the contract was concluded, and where restoration is impossible, compensation may be awarded.

The doctrine can therefore be expressed as:

Invalid contract → remove its legal effects → identify benefits transferred → return those benefits → compensate where restoration is impossible.

The UAE case law also shows that courts must carefully distinguish nullity, termination, annulment, unjust enrichment and damages. The 2026 Abu Dhabi yacht case demonstrates restitution following transactions based on forged documents; Dubai Cassation 814/2025 illustrates the distinction between restitution of principal and contractual profits; and Gjurd v Gizella provides a particularly clear illustration of why restitution ordinarily restores the pre-contractual position rather than awarding hypothetical profits.

For examination purposes, the most important formula is:

Void Contract → Nullity → Restitution → Return of Money/Property → Compensation if Restoration Is Impossible

And always remember:

Restitution restores; damages compensate; contractual profits enforce the bargain.

These are legally distinct concepts.
