Civil Law and UAE: Simulation-Based Legal Universes Diverging in Outcomes

1. Meaning of the Concept

Simulation-based legal universes means situations where the legal appearance created by a document or transaction differs from the parties' real intention.

In simple words:

One legal universe = what the document appears to say.
Another legal universe = what the parties actually intended.

A court may have to decide which legal reality should control.

For example:

A sale agreement appears to transfer property to A.

In reality, the parties intended A only to hold the property for B.

Or a company records a transaction as a genuine sale although both parties privately agreed that the sale would never actually operate.

Or parties create a nominal loan agreement while their real agreement is a different transaction.

This is generally called simulation, sham transaction, fictitious transaction, or صورية (sūriyya).

2. Current UAE Legal Framework

A major point for current UAE-law study is that Federal Decree-Law No. 25 of 2025 promulgating the new Civil Transactions Law came into force on 1 June 2026, replacing the former 1985 Civil Transactions Law. The new law contains Article 343 dealing specifically with simulation.

Article 343 – Basic Rule

The current Article 343 essentially provides:

Where contracting parties conceal a genuine contract through an apparent contract, the genuine contract governs between the contracting parties and their universal successors.

Good-faith creditors and particular successors may rely on the apparent or concealed contract and may prove the simulation by all means where they have been prejudiced.

Where interested persons have conflicting reliance on the apparent and concealed contracts, the law gives preference to those relying on the apparent contract.

Therefore, UAE law recognizes that legal appearance and actual intention can diverge.

3. What Does "Diverging Legal Universes" Mean?

The idea can be understood through five stages.

Universe A – Apparent Legal Reality

The document says:

"A sells the property to B."

The register, agreement, invoice or other document may appear to establish a sale.

Universe B – Actual Legal Reality

Evidence may show:

"A and B never intended an actual sale; B was merely holding the property for A."

The two realities are therefore different.

Universe C – Third-Party Reality

A creditor may look at the apparent transaction and reasonably believe that:

"B owns the asset."

The creditor may therefore act on the apparent legal position.

Universe D – Judicial Reality

The court must determine:

Was there a real transaction?

Was the apparent transaction only a façade?

What did the parties actually intend?

Was there a common intention?

Who is entitled to challenge the apparent transaction?

What evidence is admissible?

Universe E – Remedial Reality

After finding simulation, the court may determine whether:

the genuine transaction governs between the parties;

the simulated transaction can be invoked by a good-faith third party;

the apparent transaction should be disregarded;

creditor-protection remedies are available;

damages or other remedies follow.

4. Essential Elements of Simulation

A simulation claim generally requires careful examination of the following matters.

A. Apparent Transaction

There must first be some transaction that creates an external legal appearance.

Examples:

apparent sale;

apparent loan;

apparent transfer of shares;

apparent lease;

apparent ownership arrangement;

apparent settlement;

apparent transfer of assets.

B. Different Actual Intention

The parties' actual intention must differ from the legal appearance.

Example:

The document says:

"B purchases the property from A."

But the evidence suggests that the parties intended:

"B will merely hold the property for A."

This difference is the central issue.

C. Common Intention

A classic principle associated with sham transactions is that the parties must share an intention that the apparent document will not create the rights and obligations it appears to create.

The DIFC Court, discussing the classic sham doctrine in Royal Investment Bank Ltd v Friso Buker [2012] DIFC CFI 038, referred to the requirement of a common intention that the apparent transaction should not create the legal rights and obligations it appears to create.

This is important because:

A transaction does not become a sham merely because it is unusual, commercially artificial, or badly structured.

5. Simulation Is Different from an Unsuccessful Transaction

This distinction is very important.

Genuine but unsuccessful transaction

The parties genuinely intended the transaction to operate, but it later failed.

This is not necessarily simulation.

Simulated transaction

The parties deliberately created an appearance that was different from their real agreement.

This may constitute simulation.

Example

Company A genuinely sells goods to Company B but B later refuses to pay.

That is ordinarily a breach of contract, not necessarily simulation.

But if A and B create a sale document while both agree privately that:

no goods will be delivered;

no price will actually be paid;

the document exists only to mislead creditors,

the issue may become one of simulation.

6. Absolute and Relative Simulation

A. Absolute Simulation

The parties create an apparent transaction but intend no genuine transaction at all.

Example:

A "sells" a property to B.

But both agree:

"B will never actually become owner and no real sale will take place."

The apparent sale is merely a façade.

B. Relative Simulation

The parties create an apparent transaction to hide a different genuine transaction.

Example:

The document describes a sale.

But the parties actually intended a gift, agency, trust-like holding arrangement, loan, or another legal relationship.

Here:

Apparent transaction ≠ concealed transaction.

The current Article 343 specifically addresses the situation where a genuine contract is concealed through an apparent contract.

7. Why Outcomes Can Diverge

The same factual situation can produce different legal outcomes depending upon which "legal universe" the court is examining.

Thus, the answer may differ depending on the person's legal position.

8. Simulation and Creditor Protection

Simulation becomes particularly important when assets are allegedly moved away from creditors.

Example

A owes AED 10 million to C.

A apparently sells a valuable asset to B.

But evidence suggests:

no genuine payment occurred;

A continues controlling the asset;

B has no genuine economic involvement;

the sale was created after the creditor's claim arose.

The creditor may argue that the transaction is simulated.

The current Article 343 expressly recognizes protection for good-faith creditors and particular successors affected by simulation.

Simulation must, however, be distinguished from separate creditor-protection remedies concerning dispositions that are not necessarily simulated.

9. Simulation and Fraud Are Not Identical

They can overlap, but they are not the same.

Simulation

Focus:

What legal appearance did the parties create compared with their actual intention?

Fraud

Focus:

Was someone deliberately deceived or misled?

Creditor avoidance

Focus:

Can a debtor's transaction be made ineffective against a creditor because it prejudices the creditor?

One transaction can potentially involve all three issues.

10. Evidence of Simulation

Evidence is usually central.

Possible evidence can include:

contracts;

amendments;

payment records;

bank statements;

correspondence;

emails;

WhatsApp or electronic communications where admissible;

accounting records;

corporate resolutions;

property-registration documents;

possession and control;

conduct after the transaction;

contradictory documents;

relationships between the parties;

absence of genuine consideration;

expert evidence;

surrounding circumstances.

The important question is not merely:

"What does the document say?"

It may also be:

"What did the parties actually intend?"

11. Burden of Proof

A party alleging simulation normally needs evidence establishing the alleged divergence between appearance and reality.

In Trafigura Pte Ltd v Gupta [2026] DIFC CFI 040/2025, the court recorded UAE-law submissions concerning the burden of proving simulation and referred to an Abu Dhabi Court of Cassation decision stating that the party alleging simulation bears the burden, subject to the evidentiary rules and situations involving fraud or deceit.

This means that a bare allegation such as:

"This contract is fake"

is normally insufficient.

There must be evidence supporting the allegation.

12. Third-Party Evidence Can Be Different

An important distinction exists between:

Original contracting parties

Their evidentiary position may be subject to stricter rules concerning proof of what their written agreement actually means.

Affected third party

A creditor or other qualifying third party may have a broader ability to demonstrate that the apparent transaction does not reflect reality.

The current Article 343 expressly permits good-faith creditors and particular successors to prove simulation by all means where they have been prejudiced.

The Trafigura judgment also discusses the argument that the right to challenge simulation may extend beyond a narrow category of creditors and successors where a person's legal interests are affected.

13. Case Law

Case 1 – Trafigura Pte Ltd v Prateek Gupta & Ginni Gupta

Trafigura Pte Ltd & Trafigura India Pvt Ltd v Prateek Gupta & Ginni Gupta [2026] DIFC CFI 040/2025

This is particularly useful for understanding modern UAE-law analysis of simulation.

The court considered arguments concerning alleged sham transactions, creditor protection, Articles 394–395 of the former Civil Transactions Law, and the scope of persons who might invoke simulation.

The judgment discussed the proposition that the simulation remedy should not necessarily be understood as confined exclusively to creditors and particular successors where another interested person can demonstrate that the simulated transaction affects their rights.

Principle

Legal interest + artificial appearance + evidentiary proof = potential simulation claim.

Case 2 – Royal Investment Bank Ltd v Friso Buker

Royal Investment Bank Ltd v Friso Buker [2012] DIFC CFI 038

The DIFC Court discussed the classic legal meaning of a sham transaction.

The important idea was that the apparent documents must be intended to create an appearance of legal rights and obligations different from those the parties actually intended, and the parties must share the relevant intention.

Principle

A commercially unusual agreement is not automatically a sham.

Case 3 – Nazeer v Noah

Nazeer v Noah [2024] DIFC ARB 011

The dispute concerned a hotel-room allotment agreement alleged to be a sham arrangement created to improve performance figures.

The tribunal found that the arrangement was artificial and commercially questionable in several respects, but it nevertheless created reciprocal rights and obligations. Therefore, it did not qualify as a sham in the specific sense advanced by the claimant.

Principle

Artificiality alone does not necessarily establish simulation.

This is an excellent example of two possible "legal universes":

commercial appearance: suspicious/artificial arrangement;

legal analysis: genuine agreement because reciprocal obligations were intended.

Case 4 – Dubai Court of Cassation, Commercial Appeal No. 8 of 2025

The Trafigura judgment refers to the General Assembly of the Dubai Court of Cassation, Commercial Appeal No. 8 of 2025, in connection with the proposition that an action in simulation is not necessarily limited to creditors or successors in title.

The judgment is discussed as supporting a broader approach where a person with a sufficient legal interest may challenge a simulated transaction affecting their rights.

Principle

The identity and legal interest of the challenger can affect the available simulation remedy.

Case 5 – Abu Dhabi Court of Cassation – Simulation and Burden of Proof

The Trafigura judgment also refers to an Abu Dhabi Court of Cassation decision concerning the burden of proving simulation.

The principle recorded there was that the person alleging simulation carries the burden of proof, subject to legally permitted alternative evidence and circumstances involving fraud or deceit. Clear contractual terms cannot simply be displaced by unsupported or ambiguous allegations.

Principle

Simulation requires proof, not suspicion.

Case 6 – UAE Federal Supreme Court Authority Discussed in Trafigura

The Trafigura judgment records UAE Federal Supreme Court authority concerning the scope of persons who may invoke simulation.

The judgment describes the Federal Supreme Court approach as potentially extending beyond ordinary creditors to persons against whose interests fraud or circumvention of law is directed.

Principle

The protective purpose of simulation law can influence who has standing to challenge the artificial legal appearance.

Case 7 – Emirates NBD Bank PJSC v Almakhawi

Emirates NBD Bank PJSC v Almakhawi [2026] DIFC CFI 039/2025

This case involved allegations concerning transfers of assets and creditor protection. The proceedings included arguments concerning sham transactions under the former UAE Civil Transactions Law provisions dealing with simulation.

The case demonstrates how simulation arguments can arise where a creditor alleges that assets have been transferred in a way designed to frustrate recovery.

Principle

Simulation can become part of a broader asset-protection and creditor-enforcement dispute.

Case 8 – Abu Dhabi Court of Cassation Commercial Case No. 514/2025

This case has been reported in connection with the concept of simulated contractual arrangements.

The reported principle is that simulation involves a legal appearance deliberately created contrary to the underlying reality, with the intention of concealing the parties' actual arrangement.

Principle

The court examines the relationship between legal appearance and actual intention.

This authority should be read with care because publicly accessible reporting is less complete than the primary court record.

14. Current Law vs Former Law

This is extremely important for examinations.

Former 1985 Civil Transactions Law

Simulation was principally discussed under Articles 394–395.

Current 2025 Civil Transactions Law

Simulation is now addressed under Article 343.

The new Civil Transactions Law became effective on 1 June 2026.

Therefore, when reading older UAE judgments, students should not assume that the old article numbers are the current article numbers.

Easy memory rule

Old Law = Articles 394–395
Current Law = Article 343

15. Simulation in Property Transactions

Suppose:

A is the real economic owner;

B is shown as purchaser;

the sale document says B purchased the property;

no genuine purchase price was paid;

A continues exercising all ownership-related control;

B merely appears on documents.

The court may have to examine:

the written sale;

payment evidence;

registration;

possession;

communications;

relationship between A and B;

actual economic benefit;

intention at the time of contracting.

The result could differ depending on whether the dispute is between:

A and B;

a creditor and A;

B's successor;

a good-faith third party;

another person whose rights are affected.

This is the practical meaning of diverging legal universes.

16. Simulation in Company Transactions

Simulation can also occur in corporate structures.

Example

Company A appears to sell valuable assets to Company B.

But:

both companies are controlled by the same individuals;

the price is never paid;

A continues using the assets;

the transaction was created immediately before enforcement proceedings.

A creditor may argue:

"The apparent sale does not represent the genuine economic transaction."

The court would need to distinguish:

legitimate related-party transaction;

undervalued transaction;

fraudulent transfer;

simulated transaction.

These are not automatically the same thing.

17. Simulation in Share Transactions

The same concept can arise with shares.

Example:

A appears to transfer 60% of a company's shares to B.

But evidence indicates:

A remains the real controller;

B paid no consideration;

the parties privately agreed that B would return the shares whenever requested.

The court may examine whether:

Universe 1: B is the apparent shareholder.

Universe 2: A remains the intended beneficial/controller interest holder.

The precise legal consequences depend on the governing law, corporate records, agreements, and rights of third parties.

18. Simulation and Registration

Registration is important but should not automatically end the legal inquiry.

For example:

Registration may demonstrate the external legal position.

But a simulation dispute may ask:

Was the registered transaction genuinely intended by the parties?

This is why courts may examine the underlying agreements and surrounding evidence.

However, registration systems and property legislation may create additional protections for good-faith registered parties. Therefore, the result cannot be determined solely by alleging simulation.

19. Simulation vs Nominee Arrangement

These concepts should also be distinguished.

Nominee arrangement

A person may hold an asset or shares for another under a genuine agreement.

Simulation

The parties may create an apparent transaction that does not represent their actual intended legal relationship.

A nominee arrangement is therefore not automatically a sham.

The court must examine the actual agreement and applicable law.

20. Simulation vs Asset Concealment

Asset concealment may involve:

simulation;

fraudulent transfer;

creditor avoidance;

nominee arrangements;

unlawful disposal;

insolvency-related transactions.

These concepts overlap but have different legal tests.

Exam distinction

Simulation asks:

"Is the apparent transaction different from the real transaction?"

Creditor avoidance asks:

"Can this debtor's transaction be enforced against the creditor?"

Fraud asks:

"Was there deliberate deception?"

Insolvency avoidance asks:

"Does insolvency legislation permit the transaction to be challenged?"

21. Why Different Legal Universes Produce Different Outcomes

Consider this example:

Facts

A owes C AED 5 million.

A transfers a villa to B.

Universe 1 – Genuine Sale

The court finds:

genuine agreement;

genuine consideration;

genuine transfer;

no evidence of simulation.

Result:

The sale may remain legally effective, subject to other creditor-protection rules.

Universe 2 – Simulated Sale

The court finds:

apparent sale;

no genuine purchase;

common intention to create a false appearance.

Result:

The genuine legal relationship may control between the relevant parties, with statutory consequences for affected third parties.

Universe 3 – Genuine but Fraudulent Transfer

The sale is genuine, but A entered into it to prejudice C.

This may be analyzed under creditor-protection/non-enforceability rules rather than simulation.

Universe 4 – Legitimate Commercial Transaction

A and B are related companies, but the transaction is commercially genuine.

The fact that they are related does not by itself establish simulation.

Therefore:

Same external facts can produce different legal classifications depending on the evidence and applicable legal test.

22. Practical Judicial Test

A useful step-by-step test is:

Step 1 – Identify the apparent transaction

What does the document say?

Step 2 – Identify the alleged real transaction

What does the claimant say actually happened?

Step 3 – Compare the two

Are they materially different?

Step 4 – Examine intention

Did the parties intend the apparent rights and obligations?

Step 5 – Examine common intention

Was the appearance deliberately created?

Step 6 – Examine evidence

What documents, payments, communications and conduct prove the allegation?

Step 7 – Identify the challenger

Is the claimant:

contracting party;

universal successor;

particular successor;

creditor;

other interested third party?

Step 8 – Determine prejudice

How did the apparent transaction affect the claimant's legal rights?

Step 9 – Apply the current Article 343 framework

The current Civil Transactions Law must be used for transactions governed by the new law.

Step 10 – Select the appropriate remedy

The remedy may depend on whether the issue is:

simulation;

fraud;

creditor protection;

contractual breach;

property rights;

corporate rights;

insolvency.

23. Simple Example for Examination

A owns a villa worth AED 10 million. A owes C AED 8 million. A signs a sale agreement transferring the villa to B for AED 1 million. A continues living in the villa, B pays nothing, and private messages show that A and B agreed that B would never actually take ownership.

C challenges the transaction.

Analysis

Apparent universe:

B purchased the villa.

Actual-intention universe:

A and B intended no genuine sale.

Third-party universe:

C's recovery rights may be prejudiced.

Evidence:

no payment;

continued possession;

private communications;

relationship between parties;

timing of transaction.

Legal issue:

Whether the transaction is simulated and what consequences follow for C under the current Civil Transactions Law.

24. Important Caution About DIFC Cases

DIFC judgments are useful comparative UAE authorities, but they should not automatically be treated as binding precedents on every mainland UAE court.

This is particularly important because:

DIFC has its own court system;

DIFC has its own laws in many areas;

some DIFC cases apply common-law principles;

mainland UAE courts apply federal legislation and their own judicial framework.

Therefore, in an examination answer, write:

"The following DIFC authorities are persuasive/comparative authorities and should be distinguished from binding mainland UAE precedent."

25. Case-Law Revision Table

The first three are directly available from DIFC Courts materials; the later UAE mainland authorities are also discussed in the 2026 Trafigura judgment.

26. Exam Formula

Remember:

APPEARANCE → REAL INTENTION → COMMON INTENTION → EVIDENCE → INTEREST → PREJUDICE → REMEDY

This is the easiest way to analyze simulation-based disputes.

27. Short Exam Answer

**Simulation under UAE civil law occurs when the apparent legal transaction differs from the genuine transaction intended by the parties. Under the current Civil Transactions Law, Federal Decree-Law No. 25 of 2025, Article 343 deals with simulation. Where a genuine contract is concealed by an apparent contract, the genuine contract generally governs between the contracting parties and their universal successors. Good-faith creditors and particular successors affected by the simulation receive statutory protection and may prove simulation by all means in the circumstances specified by the law. **

**The doctrine requires careful examination of the apparent transaction, actual intention, common intention, evidence and the legal interest of the person challenging the transaction. Courts distinguish a genuine but unusual transaction from a true sham. Nazeer v Noah illustrates this distinction, while Royal Investment Bank v Friso Buker explains the classic common-intention approach to sham transactions. Recent UAE-law analysis in Trafigura v Gupta also demonstrates that simulation can intersect with creditor protection and third-party rights. **

28. Quick Revision Points

Simulation = legal appearance differs from real intention.

Current UAE provision = Article 343.

Former law = Articles 394–395.

Absolute simulation = no genuine transaction intended.

Relative simulation = apparent transaction hides a genuine transaction.

Common intention is important.

Suspicious or artificial conduct alone does not automatically prove simulation.

Evidence is essential.

Good-faith creditors receive specific statutory protection.

Third-party interests can affect the outcome.

Simulation must be distinguished from fraud and creditor avoidance.

DIFC cases are useful but are not automatically binding mainland-UAE precedents.

The same factual transaction can generate different outcomes depending on the parties' legal position.

Always identify which legal universe the court is being asked to recognize: apparent, genuine, or third-party protected reality.

Conclusion

The central idea of simulation-based legal universes diverging in outcomes is that civil law does not always stop at the external form of a transaction. A document may create one apparent legal reality while the parties' genuine intention creates another. UAE law therefore provides a mechanism for examining the difference between appearance and reality, while simultaneously protecting certain good-faith third parties.

The most important examination distinction is:

A transaction can be unusual without being simulated; simulation requires a legally significant divergence between the apparent transaction and the genuine intended transaction.

The current Article 343 framework should be read together with the developing UAE case law and older authorities, while keeping the 2026 transition from the 1985 Civil Transactions Law to the 2025 Civil Transactions Law firmly in mind.
