Civil Law and UAE Assignment of Debt and Transfer of Creditor Rights

1. Introduction

In UAE civil law, assignment of creditor rights and assignment of debt are important mechanisms for transferring obligations from one legal relationship to another.

The basic distinction is:

• Assignment of right/claim (cessions of rights): the creditor transfers its claim against the debtor to another person.
• Assignment of debt: the debtor's obligation is transferred to another debtor, subject to the legal requirements governing the transaction.
• Assignment of contract: the contractual position as a whole may be transferred, potentially involving both rights and obligations.

The UAE's current civil-law framework is governed by the Federal Decree-Law of 2025 promulgating the Civil Transactions Law, which entered into force on 1 June 2026 and replaced the former 1985 Civil Transactions Law. The new legislation modernises the UAE's civil-law framework and reorganises rules concerning obligations and contracts.

Because much of the reported UAE case law concerning assignment was decided under the former Civil Transactions Law, those decisions remain particularly useful for understanding established UAE jurisprudential principles, while current transactions must be analysed against the 2025 Civil Transactions Law.

2. Meaning of Assignment of Creditor Rights

Suppose:

A = Creditor
B = Debtor
C = New Creditor

B owes A AED 1 million.

A transfers its claim against B to C.

The result is:

C becomes the person entitled to demand payment from B.

The underlying obligation may remain substantially the same; what changes is the identity of the creditor.

Example

A construction company has an unpaid invoice of AED 5 million.

It assigns the receivable to a bank as security.

The bank can subsequently exercise the assigned claim according to the applicable agreement and law.

3. Assignment of Debt

Debt assignment operates differently.

Suppose:

A = Creditor
B = Original Debtor
C = New Debtor

B owes A AED 1 million.

B arranges for C to assume the obligation.

The legal question becomes:

Can C replace B as the debtor, and is A required to accept or consent to that substitution?

Debt transfer therefore raises greater concerns for the creditor because the creditor may have originally relied upon the financial capacity and creditworthiness of B.

4. Difference Between Assignment of Right and Assignment of Debt

5. Legal Nature of Assignment

Assignment should be distinguished from:

A. Novation

Novation replaces an existing obligation with a new obligation.

B. Assignment

Assignment generally transfers an existing right or obligation.

C. Subrogation

Subrogation places a person who has paid or satisfied an obligation into the position of another creditor in circumstances recognised by law.

D. Assignment of contract

This can transfer a broader contractual position, potentially involving:

• rights;
• duties;
• liabilities;
• contractual defences.

The distinction matters because different legal requirements can apply.

6. Why Assignment Is Important in Commercial Transactions

Assignment is particularly useful for:

• bank financing;
• factoring;
• trade receivables;
• project finance;
• construction contracts;
• insurance claims;
• debt restructuring;
• securitisation;
• corporate acquisitions;
• guarantees;
• security arrangements.

Example

A company is owed AED 20 million by customers.

Instead of waiting for payment, it assigns receivables to a financial institution.

The institution provides immediate financing.

Thus:

Receivable → Assignment → Financing → Liquidity

7. Transfer of Accessory Rights

One important legal question is:

What happens to guarantees and security supporting the assigned debt?

Generally, the value of an assigned claim would be substantially reduced if its associated security disappeared.

Accordingly, the legal analysis must consider whether rights such as:

• guarantees;
• mortgages;
• pledges;
• security interests;
• interest;
• contractual penalties;

follow the principal claim.

The precise effect depends on the applicable UAE legislation and the nature of the security.

8. Notice to the Debtor

A major practical issue is notice.

Suppose A assigns its claim against B to C.

B does not know about the assignment and pays A.

The legal consequences may depend upon:

• whether the assignment was legally effective;
• whether B was notified;
• whether B acted in good faith;
• whether registration or other formalities apply;
• the type of receivable.

Therefore, notice is an important risk-control mechanism.

Practical rule

The assignee should normally ensure that the debtor receives clear evidence of the assignment before demanding payment.

9. Debtor's Defences Against the New Creditor

Assignment should not normally transform a debtor's substantive obligations into something fundamentally different merely because the creditor has changed.

The debtor may therefore retain legally available defences arising from the underlying relationship, subject to the applicable rules governing assignment and set-off.

Example

A owes B AED 1 million.

A assigns the claim to C.

B argues:

“The goods supplied by A were defective.”

C cannot simply say:

“I am a new creditor, so that defence is irrelevant.”

The court must determine which defences remain available against the assignee under the applicable law.

10. Set-Off and Assignment

Set-off can become particularly complicated after assignment.

Example

A owes B AED 1 million.

B owes A AED 400,000.

B then assigns the AED 1 million claim to C.

The question becomes:

Can A still assert its AED 400,000 claim against the assigned debt?

The answer depends on the applicable UAE rules concerning:

• maturity;
• knowledge of assignment;
• reciprocity;
• legal requirements for set-off;
• contractual arrangements.

Therefore, set-off should always be examined when analysing an assignment transaction.

11. Assignment of Future Receivables

Commercial financing frequently involves future receivables.

For example:

A company agrees to assign to a bank:

“All receivables arising from sales during the next two years.”

This raises questions concerning:

• identification;
• determinability;
• enforceability;
• registration;
• notice;
• priority;
• competing assignments.

Modern receivables-financing arrangements therefore require careful drafting.

12. Assignment and Contractual Restrictions

A contract may provide:

“Neither party may assign its rights without the prior written consent of the other party.”

This raises an important issue.

Can the creditor nevertheless assign its claim?

The answer requires interpretation of:

• the contractual restriction;
• applicable mandatory law;
• nature of the claim;
• purpose of the restriction;
• consent requirements.

A commercial assignment should therefore always be checked against the underlying contract.

13. Case Law — UAE Court of Cassation, Civil Cassation No. 79 of 2020

Principle: Legal effect of admissions and contractual rights

The UAE Court of Cassation emphasised that a legally effective admission can bind the person making it when the requirements for an admission are satisfied.

Relevance to assignment

Assignment disputes frequently involve:

• acknowledgment of debt;
• confirmation of balances;
• acknowledgment of payment;
• acknowledgment of transfer.

A clear admission by a debtor can therefore become important evidence concerning the existence and amount of the assigned debt.

14. Case Law — UAE Court of Cassation, Commercial Cassation No. 941 of 2019

Principle: Proper legal characterisation

The Court held that courts are not bound by the parties' labels and must give the relationship its correct legal characterisation.

Relevance to assignment

Parties may call an arrangement:

• “assignment”;
• “transfer”;
• “settlement”;
• “substitution”;
• “financing arrangement.”

But the court must determine what the transaction legally constitutes.

This is particularly important where an alleged assignment may actually constitute:

• novation;
• debt restructuring;
• security;
• factoring;
• transfer of contract.

15. Case Law — UAE Court of Cassation, Civil Cassation No. 647 of 2021

Principle: Material evidence must be examined

The Court held that a judgment must demonstrate proper examination of the evidence and material defences capable of changing the result.

Relevance

Assignment disputes often depend on documents:

• assignment agreement;
• invoice;
• notice;
• acknowledgment;
• bank records;
• correspondence;
• account statements.

The court cannot simply ignore a material document demonstrating that the creditor's rights were transferred.

16. Case Law — UAE Court of Cassation, Commercial Cassation No. 215 of 2020

Principle: Expert evidence must be reasoned

The Court held that a court cannot simply rely on an expert's conclusion without adequate reasoning and examination of material defences.

Relevance

Assignment disputes involving millions of dirhams may require accounting experts to determine:

• amount of debt;
• payments;
• outstanding balance;
• assigned receivables;
• competing claims;
• interest.

An expert's calculation is evidence, not an automatic legal conclusion.

17. Case Law — UAE Court of Cassation, Commercial Cassation Nos. 1012 and 1023 of 2022

Principle: Technical findings do not determine legal questions

The Court distinguished technical matters from legal questions.

Relevance

An accounting expert might conclude:

“AED 15 million was transferred.”

But the legal question remains:

“Did the transaction legally transfer the creditor's right?”

The court must determine the legal consequences independently.

This distinction is crucial in complex receivables and debt-assignment litigation.

18. Case Law — UAE Court of Cassation, Civil Cassation No. 880 of 2021

Principle: Compensation and loss of opportunity

The Court recognised that legally compensable loss can include certain forms of future damage and loss of opportunity where properly established.

Relevance

An invalid or wrongful assignment may potentially cause:

• loss of financing;
• lost commercial opportunities;
• additional costs;
• inability to collect receivables.

However, the claimant must establish the legally compensable damage and causal connection.

19. Case Law — UAE Court of Cassation, Civil Cassation No. 99 of Judicial Year 16 (1995)

Principle: Causation and harmful acts

The Court explained direct and indirect causation and recognised the importance of an effective causal connection between wrongful conduct and damage.

Relevance to assignment

Suppose a company wrongfully assigns the same receivable to two different banks.

Potential harm may include:

• competing claims;
• payment disruption;
• financing loss;
• enforcement costs.

The court must determine:

1. what conduct occurred;
2. who was legally entitled to the receivable;
3. whether damage resulted;
4. who caused the damage;
5. what compensation is appropriate.

20. Case Law — UAE Court of Cassation, Commercial Cassation No. 767 of 2021

Principle: Technical and legal functions must be distinguished

The Court reaffirmed that experts can assist with technical questions but should not replace the court's legal reasoning.

Relevance

This is particularly important for complicated debt portfolios.

An expert may calculate:

“The assigned portfolio contains 500 receivables worth AED 70 million.”

But the court decides:

“Which of those receivables were legally assigned?”

21. Assignment of Debt and Creditor Consent

Debt assignment deserves special attention because it can change the person from whom the creditor expects performance.

Example

Bank A lends AED 10 million to Company B.

Company B attempts to transfer its debt to Company C.

Bank A may have concerns about:

• C's creditworthiness;
• available assets;
• guarantees;
• security;
• financial stability.

Consequently, the legal framework governing transfer of debt must protect the creditor's legitimate expectations.

22. Assignment and Guarantees

Suppose:

B owes A AED 5 million.

The debt is guaranteed by G.

A assigns the debt claim to C.

Questions arise:

• Does the guarantee follow the debt?
• Must G consent?
• Can G raise the same defences?
• Is the guarantee limited by its terms?
• Does a change in debtor discharge G?

These issues should be expressly addressed in the assignment documentation.

23. Assignment and Mortgages

A secured creditor may transfer a debt secured by:

• mortgage;
• pledge;
• other security interest.

The assignment should therefore be coordinated with the security documentation and applicable registration requirements.

A commercially effective transfer of the receivable does not necessarily mean every security interest automatically changes hands without compliance with applicable formalities.

24. Priority Disputes

One of the most difficult situations is:

A assigns the same receivable to C and D.

C claims:

“We received the assignment first.”

D says:

“Our assignment was properly notified to the debtor first.”

The court may have to determine priority based upon:

• date;
• validity;
• notice;
• registration;
• contractual provisions;
• applicable statutory rules.

This is particularly important in banking and factoring transactions.

25. Assignment in Insolvency

Assignment becomes even more important when the assignor becomes insolvent.

Suppose a company assigns receivables to a bank shortly before insolvency.

Questions include:

• Was the assignment genuine?
• Was it a security transaction?
• Was it preferential?
• Did the debtor receive notice?
• Was the assignment completed before insolvency?
• Does the insolvency estate challenge the transfer?

The insolvency framework must therefore be considered alongside civil-law assignment principles.

26. Assignment and Factoring

Factoring is a commercial application of assignment.

Structure

Seller → assigns receivables → Factor

The factor provides:

• immediate cash;
• collection services;
• sometimes credit protection.

Example

Company A has AED 10 million in outstanding invoices.

A transfers the receivables to Factor B for AED 9.5 million.

B then collects the receivables from customers.

The transaction combines:

• assignment;
• financing;
• collection;
• credit risk allocation.

27. Assignment of Insurance Claims

Insurance claims can also raise assignment issues.

For example:

A company suffers property damage and has an insurance claim.

It assigns its claim to a financing institution.

Questions include:

• Is the claim assignable?
• Has the insurer been notified?
• Does the policy restrict assignment?
• Does the assignee acquire all rights?
• Can the insurer raise policy defences?

The underlying insurance contract must therefore be examined.

28. Assignment of Contract vs Assignment of Debt

This distinction is essential.

Assignment of right

Only the creditor's right is transferred.

Assignment of debt

The debtor's obligation is transferred.

Assignment of contract

The contractual relationship itself may be transferred.

For example:

Construction contract

Developer ↔ Contractor

If the contractor transfers the entire contract to another company, this is considerably broader than simply assigning the right to receive AED 10 million.

It potentially transfers:

• payment rights;
• performance duties;
• warranties;
• indemnities;
• liabilities.

29. Practical Requirements for a Good Assignment Agreement

A UAE assignment agreement should ideally identify:

1. assignor;
2. assignee;
3. debtor;
4. underlying contract;
5. exact receivable;
6. amount;
7. maturity date;
8. interest;
9. security;
10. guarantees;
11. existing disputes;
12. debtor defences;
13. representations;
14. warranties;
15. notice requirements;
16. governing law;
17. dispute-resolution mechanism;
18. registration requirements where applicable.

30. Typical Assignment Dispute

Facts

Company A supplies goods worth AED 8 million to Company B.

B does not pay.

A assigns the receivable to Bank C.

B later argues:

“The goods were defective, so I owe nothing.”

Bank C responds:

“The assignment transferred the entire AED 8 million claim.”

Court must determine

1. Was there a valid underlying debt?
2. Was the claim validly assigned?
3. Was B notified?
4. What defences can B assert?
5. Was the assignment subject to contractual restrictions?
6. What amount remains outstanding?
7. Does the assignment include interest and security?

This is a classic UAE commercial-law assignment simulation.

31. Creditor Rights After Assignment

Once a valid assignment takes effect, the assignee generally seeks to obtain the legal benefit of the assigned claim.

The assignee's practical rights may include:

• demanding payment;
• commencing proceedings;
• enforcing security where legally transferred;
• receiving contractual interest;
• pursuing appropriate remedies.

However, the assignee's rights cannot simply exceed the legal rights contained in the assigned claim.

Important principle

The assignee generally receives the assigned right; it does not receive a completely new and superior right merely because it became the new creditor.

32. Debtor Protection

UAE civil law must balance two interests:

Creditor/assignee

Needs certainty that the purchased receivable is enforceable.

Debtor

Needs protection against:

• double payment;
• fraudulent assignment;
• unexpected enlargement of liability;
• loss of legitimate defences.

Therefore, notice, proof and documentary certainty are particularly important.

33. Digital Assignment

Modern commercial transactions increasingly involve:

• electronic signatures;
• electronic invoices;
• digital receivables;
• electronic notices;
• blockchain records;
• automated payment systems.

UAE electronic-transactions legislation and evidence rules become relevant when proving the existence and timing of an assignment.

The courts' broader jurisprudence on electronic evidence makes authenticity and reliability central questions.

34. Assignment and Arbitration

An assignment may contain an important arbitration question.

Example

Original contract:

“All disputes shall be referred to arbitration.”

A assigns the receivable to C.

C later brings an arbitration claim against B.

Questions:

• Does the arbitration clause transfer with the assigned claim?
• Is C bound by the original arbitration agreement?
• Is B bound to arbitrate with C?
• Did C acquire substantive rights without acquiring procedural rights?
• Does the assignment agreement contain a separate arbitration clause?

This can become one of the most complicated aspects of cross-border assignment.

35. Assignment and Choice of Law

Cross-border assignment may involve:

• UAE law;
• English law;
• DIFC law;
• another foreign law.

Suppose:

Original contract: UAE law
Assignment agreement: English law
Debtor: UAE company
Assignee: Singapore bank

The tribunal or court may need to determine different governing laws for:

• existence of the debt;
• validity of assignment;
• effectiveness against debtor;
• priority;
• security;
• insolvency consequences.

Thus, assignment is frequently a private international law problem as well as a contract-law problem.

36. Key Risks

Risk 1 — No clear identification of receivable

Solution: precisely identify the debt.

Risk 2 — Debtor not notified

Solution: documented notice and acknowledgment.

Risk 3 — Contract prohibits assignment

Solution: examine contractual restriction before execution.

Risk 4 — Competing assignments

Solution: conduct due diligence and establish priority.

Risk 5 — Security not properly transferred

Solution: coordinate assignment with security and registration requirements.

Risk 6 — Underlying debt disputed

Solution: conduct due diligence on the debtor's defences.

Risk 7 — Insolvency

Solution: verify effectiveness and priority before insolvency.

37. Case-Law Principles at a Glance

Important: These authorities are not all cases directly deciding a modern assignment-of-receivables dispute. They are UAE Court of Cassation authorities supplying the underlying principles of contractual interpretation, evidence, admissions, causation, expert evidence and damages that are relevant when an assignment dispute is litigated.

38. Exam-Oriented Analysis

For an assignment-of-debt problem, use this sequence:

Step 1 — Identify the original obligation

Who owed what to whom?

Step 2 — Identify the transaction

Is it:

• assignment of right;
• assignment of debt;
• novation;
• subrogation;
• assignment of contract?

Step 3 — Check validity

Was the transfer legally valid?

Step 4 — Check contractual restrictions

Does the original contract restrict assignment?

Step 5 — Check notice

Was the debtor notified?

Step 6 — Check defences

What defences does the debtor retain?

Step 7 — Check security

What happens to:

• guarantee;
• mortgage;
• pledge;
• other security?

Step 8 — Check competing claims

Has the same receivable been transferred more than once?

Step 9 — Check governing law

Is UAE law applicable?

Step 10 — Determine remedy

Possible remedies include:

• payment;
• declaration of entitlement;
• enforcement;
• damages;
• interest;
• costs.

39. Conclusion

Assignment of debt and transfer of creditor rights are central mechanisms of UAE commercial civil law. They allow businesses and financial institutions to transfer receivables, restructure obligations, obtain financing and manage commercial risk.

The essential distinction is:

Assignment of creditor rights changes the person entitled to receive performance, whereas assignment of debt changes the person responsible for performing the obligation.

The legal analysis must then consider consent, validity, notice, debtor defences, security, set-off, priority, contractual restrictions, insolvency and governing law.

The UAE Court of Cassation authorities discussed above—particularly Civil Cassation No. 99/1995, Civil Cassation No. 79/2020, Civil Cassation No. 647/2021, Civil Cassation No. 880/2021, Commercial Cassation No. 941/2019, Commercial Cassation No. 215/2020, Commercial Cassation No. 767/2021, and Commercial Cassation Nos. 1012/1023/2022—provide important principles for resolving the evidentiary, contractual, causation and damages questions that arise in assignment disputes.

Final principle

A valid transfer of a creditor's right should not ordinarily enlarge the debtor's underlying obligation, while a transfer of the debtor's obligation requires careful protection of the creditor because the identity and creditworthiness of the performing party may materially affect the creditor's rights.
