Below is a detailed UAE-focused explanation. One important terminology point: “preference transaction avoidance” can refer to two related but distinct ideas in UAE law—(1) avoidance/non-enforceability of transactions that prejudice creditors under the Civil Transactions Law, and (2) insolvency-specific avoidance of preferential or harmful transactions under the Financial and Bankruptcy Law.

Civil Law and UAE: Preference Transaction Avoidance Rules

1. Introduction

Preference transaction avoidance rules are designed to prevent a debtor from using transactions to place one creditor, a related person, or another beneficiary in a better position at the expense of the debtor's general body of creditors.

In practical terms, the problem arises when a financially distressed debtor:

pays one creditor before other creditors;

grants new security for an old unsecured debt;

transfers assets to a related party;

sells property at a substantially undervalued price;

makes a gift when creditors are unpaid;

repays a debt before its maturity;

transfers assets after a creditor has commenced proceedings;

disguises a transfer through a sham or simulated transaction; or

otherwise reduces the assets available for creditor enforcement.

UAE law deals with these problems through two complementary systems:

Civil-law creditor protection and non-enforceability rules under the Civil Transactions Law; and

Special insolvency avoidance rules under Federal Decree-Law No. 51 of 2023 on Financial Restructuring and Bankruptcy.

The 2023 Bankruptcy Law specifically identifies several transactions that cannot be invoked against creditors when undertaken within the statutory suspect periods. These include gifts, materially unbalanced transactions, premature repayment, unusual repayment methods and new security for existing debt. (Ministry of Education)

2. Current UAE Legal Position

A major change must be kept in mind for examinations and current legal research.

Federal Decree-Law No. 25 of 2025 promulgating the new Civil Transactions Law came into force on 1 June 2026 and replaced the former 1985 Civil Transactions Law. The provisions concerning creditor protection have therefore been renumbered. (LEXAI)

The new Civil Transactions Law continues the basic creditor-protection architecture but places the relevant provisions in different articles.

The current provisions include:

Article 343 — simulation/sham arrangements;

Articles 344–350 — non-enforceability of the debtor's dispositions against creditors;

related provisions concerning the general protection of the creditor's claim.

Historical UAE cases frequently refer to the former 1985 provisions, particularly Articles 391 and 396–400. Those authorities remain useful for understanding the judicial doctrine, but their article numbers should not be confused with the numbering of the current 2025 Civil Transactions Law.

3. Meaning of a Preference Transaction

A preference transaction occurs when a debtor, particularly while financially distressed, deals with its assets or liabilities in a manner that gives a particular creditor or beneficiary an advantage that adversely affects the collective position of creditors.

Simple example

A owes:

Bank A — AED 10 million;

Bank B — AED 8 million;

Supplier C — AED 5 million.

A becomes unable to pay its debts.

Instead of preserving its assets for collective distribution, A:

pays Bank A AED 10 million in full;

grants Bank A additional security for an old unsecured debt;

transfers a villa to the director's relative; or

sells shares to an affiliated company for AED 1 million when they are worth AED 5 million.

Such conduct may trigger creditor-protection or insolvency avoidance rules.

The fundamental principle is:

A debtor should not be permitted to diminish the common pool of assets available to creditors through transactions that the law treats as prejudicial or preferential.

4. General Guarantee of Creditors

The starting principle is that the debtor's assets constitute the general economic security for creditors.

Historically, former Article 391 of the Civil Transactions Law expressed this principle. Recent Dubai Court of Cassation jurisprudence has continued to describe the debtor's assets as the general guarantee for creditors.

In Dubai Court of Cassation Case No. 510/2024, the Court explained that the creditor is entitled to monitor what enters and leaves the debtor's patrimony and may use an unwinding claim to protect the general guarantee from fraudulent or negligent diminution. (Serle Court)

The principle can be represented as:

Debtor's Assets → General Guarantee → Creditor Protection → Avoidance/Non-enforceability

5. Civil Transactions Law and Non-Enforceability

The current Civil Transactions Law retains a system under which certain dispositions of an indebted debtor may be declared non-enforceable against creditors.

This is important because the remedy does not necessarily mean that the underlying transaction disappears between all parties.

Instead, the creditor may obtain protection so that the transaction cannot be relied upon against the creditor's enforcement rights.

This is conceptually different from saying:

“The contract never existed.”

The more precise idea is:

“The transaction cannot be used against the creditor to defeat the creditor's legally protected claim.”

6. Current Article 344 – Gratuitous Dispositions

Under the renumbered 2025 Civil Transactions Law, Article 344 deals with the non-enforceability of certain gratuitous dispositions.

The basic policy is that where the debtor's financial position is sufficiently encumbered by debt, gratuitous transactions that are not legally required or customary may be challenged by creditors.

Example

A debtor owing AED 20 million gives a valuable Dubai property worth AED 10 million to a friend without consideration.

If the statutory conditions are satisfied, the creditor may seek a declaration that the disposition is not enforceable against the creditor.

Important point

The creditor's objective is generally not simply to obtain a declaration that:

“the debtor is a bad person.”

The objective is to protect the asset base against which the creditor's debt can be enforced.

7. Current Article 345 – Dispositions After Creditors Demand Payment

Article 345 addresses a more serious situation.

Where creditors demand payment from a debtor whose debts encompass the debtor's property, the debtor cannot freely make gifts or dispose of property for consideration in a way covered by the statutory rule.

Creditors can seek:

a declaration that the disposition is non-enforceable against them;

sale of the relevant property; and

distribution of the proceeds according to law.

This demonstrates that UAE law distinguishes ordinary commercial dealings from transactions that interfere with the creditor's general security.

8. Burden of Proof

Under the current framework, the creditor and debtor have different evidentiary responsibilities.

Where a creditor alleges that the debtor's debt encompasses the debtor's property, the creditor establishes the relevant debt.

The debtor may then have to establish that its assets exceed the amount of the relevant obligations.

This is important because creditor avoidance litigation is highly dependent on:

asset schedules;

bank statements;

valuation evidence;

corporate records;

property records;

payment histories;

related-party documentation; and

evidence concerning the timing of transactions.

9. The Paulian Action

The traditional UAE Civil Code doctrine is commonly described as the Paulian action or actio Pauliana.

It permits creditors, subject to statutory requirements, to challenge dispositions that damage the creditor's ability to recover.

The underlying idea is:

Debtor's asset → Improper disposition → Reduction of creditor's guarantee → Creditor seeks non-enforceability

The 2026 DIFC judgment in Trafigura Pte Ltd & Trafigura India Pvt Ltd v Prateek Gupta & Ginni Gupta, DIFC CFI 040/2025 discusses the UAE-law Paulian action extensively and identifies the traditional requirements as including:

insolvency of the debtor;

contemporaneous creditorship;

intention to defraud; and

detriment to the creditor.

The judgment also discusses the distinction between the Paulian action, simulation and the indirect action. (DIFC Courts)

Because the case involved UAE-law analysis before the DIFC Court, it should be treated as an illustrative UAE-law authority rather than as a mainland UAE Court of Cassation judgment.

10. Preference Versus Fraudulent Transfer

These concepts overlap but are not identical.

Preferential transaction

The debtor gives one creditor an advantage over the collective body of creditors.

Example:

Paying Creditor A AED 5 million shortly before insolvency while leaving similarly situated creditors unpaid.

Fraudulent transfer

The debtor transfers assets to defeat or prejudice creditors.

Example:

Transferring a villa to a relative without genuine consideration so that creditors cannot execute against it.

Sham transaction

The parties create an apparent transaction while concealing their real agreement.

Example:

A “sale” is documented, but the debtor remains the real beneficial controller and no genuine sale occurred.

Thus:

Preference ≠ Fraud ≠ Simulation, although one transaction can potentially involve more than one category.

11. Bankruptcy Law: Special Preference-Avoidance Rules

Federal Decree-Law No. 51 of 2023 contains a more specific insolvency regime.

Article 148 deals with debtor dispositions that cannot be invoked against creditors.

During the statutory period preceding cessation of payment, the following categories are particularly important:

A. Donations and gifts

Except for small customary gifts.

B. Materially unbalanced transactions

Transactions where the debtor's obligations are significantly disproportionate to those of the other contracting party.

C. Premature repayment

Repayment of a debt before maturity.

D. Unusual repayment

Payment in a manner different from the method ordinarily used for that type of debt.

E. Unusual consideration

Payment of an existing debt using consideration different from the agreed consideration.

F. New security for old debt

Creation of a new guarantee or security over the debtor's assets for an existing debt, subject to the statutory commercial-justification rules.

These categories are expressly addressed by Article 148. (Ministry of Education)

12. The Suspect Period

The timing of the transaction is critical.

Under Article 148, the principal statutory period is connected to the six months preceding the cessation-of-payment date.

However, the law contains an important extension for transactions involving an insider or related party, for which the relevant period can extend to two years.

Therefore:

This is why transaction chronology is one of the most important parts of avoidance litigation.

13. Knowledge of Financial Distress

The Bankruptcy Law also distinguishes between automatically vulnerable categories and transactions requiring additional examination.

Article 148 permits the Bankruptcy Court, in specified circumstances, to make a disposition unenforceable where:

the disposition harmed creditors; and

the counterparty knew or should have known that the debtor had ceased paying debts or was financially deficient.

This introduces an important distinction between:

objective transaction characteristics

and

knowledge of the debtor's financial condition.

14. Good-Faith Commercial Defence

The Bankruptcy Law contains a significant safeguard for legitimate commercial transactions.

Article 150 permits the Bankruptcy Court to dismiss the relevant avoidance action where it is satisfied that:

the debtor acted in good faith;

the debtor was genuinely attempting to conduct its business; and

there were reasons to believe the transaction could benefit the business.

This prevents the avoidance regime from automatically converting every transaction occurring near insolvency into an unlawful preference. (Legal Advice Middle East)

15. Related-Party Transactions

Related-party transactions receive particularly careful scrutiny.

Why?

Because the risk of manipulation is greater where:

the transferee is a director;

the transferee is a shareholder;

the transferee is a family member;

the debtor and transferee are controlled by the same person;

the debtor transfers assets to a group company; or

the transaction lacks ordinary commercial documentation.

The Bankruptcy Law therefore extends the relevant avoidance period for specified insider or related-party transactions.

16. New Security for Old Debt

One of the clearest examples of a potentially preferential transaction is:

New security for an old unsecured debt.

Example:

A owes Bank B AED 10 million.

The loan has already been advanced without security.

When A becomes financially distressed, A suddenly grants Bank B a mortgage over valuable property.

This can improve Bank B's recovery position at the expense of unsecured creditors.

Article 148 specifically addresses the creation of new guarantees over debtor assets for repayment of previous debt, subject to its statutory exceptions. (Legal Advice Middle East)

17. Mortgage and Lien Avoidance

Article 149 separately deals with registration of mortgages and liens.

A court may order the relevant registration ineffective against creditors where the statutory conditions are satisfied, particularly where the registration occurs after cessation of payment and the creditor knew of that cessation.

However, the law protects certain pre-existing security arrangements, including specified circumstances where the security right was already established or registered pursuant to an earlier ratified agreement.

This prevents the avoidance mechanism from unnecessarily disturbing legitimate pre-existing security rights. (Legal Advice Middle East)

18. Article 151 – General Civil-Law Avoidance in Bankruptcy

Article 151 is especially important.

It allows the Trustee to seek invalidation/non-enforceability of debtor acts occurring before commencement of bankruptcy proceedings where those acts prejudice creditors, using the Civil Transactions Law rules concerning non-enforceability.

The effect can extend to all creditors, including creditors whose rights arose before or after the disposition.

Thus, the Bankruptcy Law and Civil Transactions Law operate together rather than as completely separate systems. (Legal Advice Middle East)

19. Effect of an Avoidance Judgment

Under Article 152, where a disposition is invalidated or rendered unenforceable against creditors, the recipient may have to:

return the money received;

return the asset;

return the value of the asset where restitution in kind is impossible; and

account for relevant interest or benefits.

The recipient may, subject to the statutory rules, have a corresponding claim concerning consideration provided to the debtor.

The aim is therefore restoration of the bankruptcy estate, not simply punishment.

20. Case Law

Case 1 — Dubai Court of Cassation, Cassation No. 510/2024

This is an important modern authority on creditor protection.

The Court emphasized that the debtor's assets constitute the general guarantee for creditors and that creditors are entitled to monitor changes to that asset base.

The judgment recognized the unwinding claim as a mechanism through which a creditor can protect the general guarantee against fraudulent or negligent diminution. (Serle Court)

Principle

The debtor cannot use transactions to improperly diminish the asset pool constituting the general security of creditors.

Case 2 — Dubai Court of Cassation, Cassation No. 231/2022

This authority has been cited in UAE legal analysis concerning Articles 391 and 396–398 of the former Civil Transactions Law.

The Court's stated approach was that the debtor's assets form the general guarantee for creditors and that creditors may monitor what enters and leaves the debtor's patrimony.

A creditor's non-enforceability action protects the creditor against the consequences of a debtor's disposition that reduces the general guarantee.

The important distinction is that the transaction may remain effective between the debtor and recipient while being ineffective against the challenging creditor.

This authority is a historical authority under the former 1985 Civil Transactions Law; its article numbering should not be treated as the numbering of the current 2025 law. (ResearchGate)

Case 3 — Dubai Court of Cassation, Cassation No. 174/2022

This case is another authority cited for the principle that:

debtor assets constitute general security for creditors;

creditors may monitor the debtor's patrimony; and

dispositions diminishing that guarantee may be challenged under the statutory creditor-protection framework.

The case is particularly useful for explaining the protective purpose of the non-enforceability remedy.

Again, it is a former-Civil-Code authority, so the present-day statutory provisions must be consulted alongside the historical case. (ResearchGate)

Case 4 — Dubai Court of Cassation, Cassation No. 151/2021

This case is important for the requirements governing the Paulian/non-enforceability action.

It has been cited in later UAE-law analysis for the proposition that the creditor's status and the timing of the creditor's claim are important.

In particular, Article 397 of the former Civil Transactions Law was understood as imposing specific temporal requirements for the creditor's challenge.

The case therefore demonstrates that not every asset transfer made by a financially troubled debtor is automatically avoidable. The statutory requirements must be established.

The authority is historical because it concerns the former Civil Transactions Law. (DIFC Courts)

Case 5 — Dubai Court of Cassation, Cassation No. 535/2024

This case was also cited in later UAE-law analysis concerning the requirements for a Paulian action.

The authority reinforces the importance of:

creditor status;

the existence of the relevant debt;

timing of the disposition;

the debtor's financial position; and

prejudice to the creditor.

It illustrates why a creditor cannot simply identify a suspicious transaction and automatically obtain avoidance.

The statutory conditions must be satisfied.

The case concerns the former Civil Transactions Law and should therefore be used with appropriate historical qualification. (DIFC Courts)

Case 6 — Dubai Court of Cassation, Commercial Appeal No. 769/2025

This is a particularly useful recent authority.

In its judgment dated 13 August 2025, the Dubai Court of Cassation considered the application of the former Articles 396–400 concerning non-enforceability of dispositions.

The Court recognized an important limitation concerning payment of lawyer's professional fees pursuant to a valid fee agreement.

Such payment was treated differently from a transaction intended to prejudice the general creditor guarantee and was not automatically subject to challenge under the non-enforceability action. (M and Co)

Importance

This case demonstrates that:

A payment made shortly before insolvency is not necessarily a preference merely because it reduces the debtor's cash.

The court must examine the legal nature and commercial context of the payment.

Case 7 — Emirates NBD Bank PJSC v Almakhawi & Others, DIFC CFI 039/2025

This 2026 DIFC Court decision provides a modern illustration of creditor asset-dissipation litigation involving UAE Civil Code concepts.

The bank alleged that assets had been transferred to family members to frustrate enforcement and relied on:

UAE Civil Code creditor-protection principles;

unwinding claims;

simulation provisions; and

provisions concerning non-enforceability of dispositions.

The case discusses former Articles 394, 395 and 397 and cites Dubai Court of Cassation Case No. 510/2024 on the general guarantee of creditors. (DIFC Courts)

Significance

It demonstrates how avoidance litigation can involve several alternative legal theories simultaneously:

agency + sham transaction + creditor prejudice + unwinding + damages.

Because it is a DIFC proceeding applying UAE-law concepts, it should be treated as an illustrative/special-jurisdiction authority rather than as a binding mainland UAE Court of Cassation precedent.

Case 8 — Trafigura Pte Ltd & Trafigura India Pvt Ltd v Prateek Gupta & Ginni Gupta, DIFC CFI 040/2025

This recent DIFC decision provides an extensive discussion of UAE-law creditor remedies.

The Court considered:

indirect action;

simulation;

Paulian action;

creditor protection;

asset transfers;

enforcement against assets; and

the requirements for challenging transactions.

The judgment records UAE-law submissions that the Paulian action requires consideration of insolvency, contemporaneous creditorship, fraudulent intention and creditor prejudice. It also discusses Dubai Court of Cassation Cases 769/2025, 151/2021 and 535/2024. (DIFC Courts)

Importance

The case is especially useful for understanding the relationship between:

Civil Code creditor remedies

and

insolvency/bankruptcy avoidance mechanisms.

21. Preference and Ordinary Commercial Payments

Not every payment made by a distressed debtor is automatically avoidable.

Courts may examine:

whether the debt was genuinely due;

whether payment followed the contractual arrangement;

whether the payment was made in the ordinary course of business;

whether the payment gave the creditor an extraordinary advantage;

whether the counterparty knew about the debtor's financial distress;

whether the payment was supported by a legitimate commercial reason; and

whether the transaction falls within a specific statutory avoidance category.

This explains the importance of the good-faith/commercial-purpose defence under Article 150 of the Bankruptcy Law. (Legal Advice Middle East)

22. Preference and Related Parties

A transaction involving a related party is more closely scrutinized because it may involve:

lack of arm's-length negotiation;

hidden consideration;

undervaluation;

disguised gifts;

sham transactions;

retention of beneficial ownership;

insider knowledge of financial distress.

The statutory two-year period for certain insider/related-party transactions reflects this increased concern.

23. Preference Through Undervalue

Suppose:

Market value of property = AED 20 million;

Debtor sells it to an affiliated company = AED 5 million;

Debtor owes creditors = AED 30 million.

The relevant question is not merely:

“Was there a sale contract?”

The court may ask:

Was the consideration genuine?

Was AED 5 million commercially justified?

Was the debtor insolvent?

Was the transaction within the statutory period?

Was the purchaser related to the debtor?

Did the purchaser know of the financial distress?

Did the transaction prejudice creditors?

Was there an intention to defeat enforcement?

24. Preference Through Security

A particularly important pattern is:

Old unsecured debt → debtor becomes distressed → new mortgage/security → bankruptcy

This can be problematic because the creditor changes from:

unsecured creditor

to:

secured creditor.

The result may reduce the recovery available to other creditors.

Article 148 specifically addresses creation of new security for an existing debt, subject to its statutory exceptions and commercial-justification provisions. (Legal Advice Middle East)

25. Preference Through Early Payment

Example:

A debt is due on 31 December.

The debtor becomes financially distressed in June.

The debtor pays one creditor in July while other creditors remain unpaid.

The court may consider:

whether the debt was actually due;

whether early payment was contractually permitted;

whether the transaction falls within Article 148;

whether the payment was made within the suspect period;

whether the creditor knew of the financial distress; and

whether a legitimate commercial justification existed.

Therefore:

Early payment is a risk indicator, not an automatic finding of unlawful preference.

26. Preference Through Unusual Payment

A debtor may also attempt to prefer a creditor by paying in an unusual manner.

For example:

transferring valuable property instead of cash;

assigning valuable receivables;

giving shares instead of money;

transferring another asset unrelated to the debt.

Article 148 specifically addresses repayment through consideration different from the agreed consideration, subject to its statutory provisions. (Legal Advice Middle East)

27. Simulation and Preference

A preference transaction can be disguised.

Example:

A owes Bank B AED 10 million.

A “sells” property to C for AED 10 million.

However:

C never pays;

A continues controlling the property;

A continues receiving its income;

the sale price is artificial.

This may raise both:

simulation/sham transaction issues, and

creditor-prejudice/avoidance issues.

The current Civil Transactions Law retains the simulation doctrine in Article 343. (LEXAI)

28. Indirect Action Versus Preference Avoidance

The indirect action is another creditor-protection mechanism.

Under the former Civil Code provisions discussed in recent UAE jurisprudence, a creditor could, subject to statutory conditions, exercise certain rights belonging to the debtor where the debtor's failure to do so could increase or cause bankruptcy.

The benefit goes into the debtor's patrimony and therefore becomes available as security for the creditors generally.

This differs from the Paulian action:

The recent Trafigura judgment discusses this distinction under UAE law. (DIFC Courts)

29. Civil Law Avoidance Versus Bankruptcy Avoidance

30. Effect on Third Parties

An avoidance judgment does not necessarily mean that the transaction disappears for every purpose.

The central question is often:

Against whom is the transaction ineffective?

This is a major civil-law concept.

For example:

A transfers property to B.

B may remain the contractual owner as between A and B, but the creditor may obtain a judgment preventing B from relying on that transfer against the creditor's enforcement rights.

This explains the expression:

“non-enforceability” rather than simply “absolute nullity.”

31. Burden of Proof and Evidence

Preference-avoidance disputes are strongly evidence-based.

Important evidence includes:

Financial evidence

bank statements;

audited accounts;

cash-flow statements;

creditor schedules;

loan statements.

Transaction evidence

sale agreements;

invoices;

valuation reports;

payment confirmations;

security documents.

Relationship evidence

shareholding records;

directors;

family connections;

group-company structures.

Timing evidence

date of debt;

date of demand;

date of payment;

date of transfer;

cessation-of-payment date;

bankruptcy commencement date.

Knowledge evidence

correspondence;

default notices;

financial statements;

restructuring negotiations;

insolvency warnings.

32. Practical Example

Assume Company X owes:

Total = AED 30 million.

Company X owns assets worth AED 25 million.

Two months before cessation of payment:

Company X pays Bank A AED 10 million early;

grants Bank A a mortgage over property for an old unsecured debt;

sells another property worth AED 8 million to its related company for AED 3 million;

gives AED 1 million to a shareholder.

Potential issues:

Transaction 1

Early repayment → Article 148 analysis.

Transaction 2

New security for old debt → Article 148 analysis.

Transaction 3

Material imbalance + related party → Article 148 and related-party provisions.

Transaction 4

Gift → Civil Transactions Law and Bankruptcy Law avoidance principles.

The Trustee may therefore investigate the entire transaction history rather than treating each transaction in isolation.

33. Key Judicial Principles

The major principles emerging from the authorities are:

Principle 1

The debtor's assets constitute the general guarantee for creditors.

Principle 2

Creditors can challenge transactions that improperly diminish that guarantee.

Principle 3

Not every transaction occurring near insolvency is automatically avoidable.

Principle 4

Timing is crucial.

Principle 5

Related-party transactions receive heightened scrutiny.

Principle 6

A transaction can potentially raise several legal theories simultaneously.

Principle 7

A legitimate commercial transaction should not automatically be treated as a preference.

Principle 8

Simulation is distinct from an ordinary undervalue transaction.

Principle 9

The Bankruptcy Law supplements rather than completely replaces civil-law creditor remedies.

Principle 10

Historical case law under the 1985 Civil Transactions Law must be read against the current 2025 Civil Transactions Law.

34. Important Distinction: Preference Is Not Simply “First Payment”

A common examination mistake is:

“The first creditor to receive payment has been preferred.”

That is too simplistic.

Preference analysis requires consideration of:

Transaction + Timing + Financial Condition + Creditor Position + Statutory Category + Commercial Justification + Knowledge + Prejudice

Thus:

Payment ≠ Automatically Preferential

and:

Preference ≠ Automatically Fraudulent

35. Six Important Case Laws – Quick Revision Table

36. Exam-Oriented Formula

Remember:

P-T-F-K-H-R

P = Preferential transaction
T = Timing/suspect period
F = Financial distress
K = Knowledge of counterparty
H = Harm to creditors
R = Restoration/avoidance remedy

A second formula:

ASSET → TRANSFER → PREJUDICE → CHALLENGE → RESTORATION

37. One-Line Exam Answer

UAE preference transaction avoidance rules protect the general guarantee of creditors by permitting specified debtor transactions that prejudice or improperly prefer particular creditors or beneficiaries to be rendered non-enforceable, with the Financial and Bankruptcy Law providing additional insolvency-specific avoidance rules for gifts, undervalue transactions, premature or unusual repayments and new security for existing debts.

38. Conclusion

Preference transaction avoidance in UAE civil law is fundamentally based on preserving the debtor's asset pool for legitimate creditor claims.

The current legal framework should be understood as a combination of:

Civil Transactions Law creditor-protection rules;

simulation and sham-transaction principles;

Paulian/non-enforceability remedies;

Financial and Bankruptcy Law avoidance provisions;

special rules for insider and related-party transactions;

judicial scrutiny of timing, insolvency, prejudice and commercial justification.

The most important practical distinction is:

A lawful commercial payment is not automatically a preference, but a transaction that improperly removes value from the debtor's estate or gives an unjustified advantage to a particular creditor can become subject to avoidance or non-enforceability rules when the statutory conditions are satisfied.

The modern UAE position therefore attempts to balance creditor equality and asset preservation with the need to protect legitimate commercial transactions and good-faith business activity. (Legal Advice Middle East)

This topic is closely connected with fraudulent conveyance, creditor asset protection, Paulian actions, related-party transactions, and UAE bankruptcy clawback rules; those can be treated separately because each has different statutory requirements.
