Civil Law and UAE: Novation and Assignment Principles

1. Introduction

Novation and assignment are important mechanisms for transferring or restructuring contractual rights and obligations in UAE civil law.

Although they are sometimes used interchangeably in commercial documents, they are legally different:

Assignment generally transfers a right/claim from the existing creditor to another person.

Assignment of debt transfers an existing obligation/debt from the original debtor to another person, subject to the statutory consent requirements.

Novation is a more comprehensive substitution or transformation of an existing obligation or contractual relationship, normally involving the agreement of the relevant parties and replacement of the former obligation.

The current UAE framework is particularly important because Federal Decree-Law No. 25 of 2025 promulgating the Civil Transactions Law came into force on 1 June 2026, replacing the former 1985 Civil Transactions Law. The new law contains a dedicated modern framework for assignment. (UAE Legislation)

2. Current UAE Statutory Framework

The current Civil Transactions Law places assignment in Part Four — Transfer of the Obligation.

The principal provisions are:

Articles 405–417 — assignment of rights;

Articles 418–424 — assignment of debts;

subsequent provisions deal with extinction/release and related matters. (UAE Legislation)

This is a significant development because the new legislation expressly and systematically regulates both:

transfer of rights

and

transfer of debts.

3. Meaning of Assignment

Assignment means the transfer of a legally transferable right from one person to another.

Example

A owes B AED 1 million.

B is the creditor.

B assigns the receivable to C.

The relationship changes:

Before

A → B

After assignment

A → C

The underlying debt may remain substantially the same; the identity of the person entitled to receive performance changes.

4. Assignment of Rights — Article 405

Article 405 provides that a creditor may assign their right to another person unless assignment is prohibited by:

law;

agreement between the contracting parties; or

the nature of the obligation.

Importantly, the validity of the assignment is not generally conditional upon the debtor's consent. (UAE Legislation)

Basic principle

Creditor can transfer a transferable claim, subject to legal and contractual restrictions.

5. When Assignment Is Not Permitted

Assignment may be restricted where:

A. Law prohibits it

A statute may make a particular right non-transferable.

B. Contract prohibits it

The original contract may contain:

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

C. Nature of the right prevents transfer

Certain rights may be so personal or connected with the original parties that assignment is inappropriate.

Therefore:

Not every contractual right is automatically assignable.

6. Assignment Does Not Normally Require Debtor Consent

This is one of the most important current rules.

Article 405 states that the validity of assignment is not conditional upon the debtor's consent. (UAE Legislation)

However, this must be distinguished from enforceability against the debtor or third parties.

Article 407 provides that assignment is not enforceable against the debtor or a third party until it is:

accepted by the debtor; or

notified to the debtor.

Where acceptance is relied upon for enforceability against a third party, the acceptance must have a fixed date. (UAE Legislation)

Therefore:

Validity of assignment

≠

enforceability against debtor

This distinction is extremely important.

7. Example of Assignment

A owes B AED 500,000.

B assigns the receivable to C.

Between B and C

The assignment may be valid if statutory conditions are satisfied.

Against A

A must receive notice or accept the assignment before C can ordinarily rely on the assignment against A under Article 407.

Thus:

B → C

transfers the claim,

but

A's knowledge/acceptance

affects enforceability.

8. Scope of Assigned Right

Article 406 provides that a right can only be assigned to the extent that the right itself is capable of attachment. (UAE Legislation)

This means the assignor cannot transfer something that legally cannot be subjected to the relevant enforcement or transfer mechanism.

The court therefore examines:

nature of the right;

statutory restrictions;

contractual restrictions;

attachment/enforcement rules.

9. Assignment of Debt

Assignment of debt is fundamentally different from assignment of a right.

Under Article 418, a debtor may transfer their obligation to another person unless prohibited by:

law;

agreement;

nature of the obligation.

But an assignment of debt requires the consent of both the assignee and the creditor. (UAE Legislation)

Example

A owes B AED 1 million.

C agrees to assume A's debt.

The structure is:

Original

A → B

After debt transfer

C → B

But the creditor B's consent is required under Article 418.

10. Why Creditor Consent Matters

The creditor is concerned about creditworthiness.

Suppose:

A has substantial assets.

C has no assets.

If A could simply replace himself with C without the creditor's approval, the creditor's position could materially deteriorate.

Therefore:

Assignment of a right primarily changes the creditor.

Whereas:

Assignment of debt changes the debtor and therefore requires stronger creditor protection.

11. Effect of Creditor Acceptance — Article 419

Article 419 establishes an important consequence.

If the creditor accepts the debt assignment:

The original debtor is discharged as against the creditor and the debt transfers to the new debtor.

If the creditor expressly or implicitly refuses:

The original debtor remains liable.

The law also treats expiry of a reasonable approval period without approval as refusal where the statutory conditions are met. (UAE Legislation)

12. Securities Following the Debt

Article 421 provides that the assigned debt retains its securities despite the change in the debtor.

However:

A guarantor, whether real or personal, does not remain bound unless the guarantor consents to the debt assignment. (UAE Legislation)

This is a major practical rule.

Example

A owes B AED 1 million.

C assumes A's debt.

D is A's personal guarantor.

After the debt assignment:

C → B

But D's guarantee does not automatically continue unless D consents.

13. Mortgage and Assignment of Debt

Article 424 specifically addresses mortgaged property.

Sale of mortgaged property does not automatically transfer the secured debt to the purchaser merely because ownership changes.

If seller and purchaser agree that the debt should be transferred, creditor consent must be obtained before registration, subject to applicable special legislation. (UAE Legislation)

Principle

Transfer of ownership ≠ automatic transfer of secured debt.

14. Defences Available to Assignee

Article 423 provides that the assignee may raise against the creditor:

defences that the original debtor could have raised; and

defences arising from the assignment contract. (UAE Legislation)

This prevents the transfer from arbitrarily depriving the debtor of legitimate defences.

15. Solvency of Assignee

Article 422 provides that the original debtor warrants the assignee's solvency at the time the creditor approves the assignment unless the parties agree otherwise. (UAE Legislation)

This is relevant where a creditor accepts a transfer based on the financial position of the replacement debtor.

16. Meaning of Novation

Novation is different from ordinary assignment.

In a novation, the parties intend to replace an existing obligation or contractual relationship with a new one.

The critical idea is:

Old obligation → New obligation

rather than merely:

Old creditor → New creditor.

17. Assignment vs Novation

18. Novation Is More Than Assignment

Suppose:

A contracts with B.

C later purchases A's receivable.

That is generally:

Assignment

But suppose:

A, B and C agree that:

A will leave the contractual relationship;

C will replace A;

B accepts C as the new contracting party;

C assumes A's obligations;

A is released.

That is much closer to:

Novation.

19. Essential Elements of Novation

A useful analysis requires examining:

1. Existing obligation

There must be an existing legal relationship capable of being replaced.

2. New obligation or substituted party

The new arrangement must differ legally from the old arrangement.

3. Intention to novate

The parties must intend that the old obligation be replaced.

4. Consent

The relevant parties must agree to the substitution.

5. Clear identification

The transaction should identify:

outgoing party;

incoming party;

continuing party;

obligations transferred;

obligations discharged;

security arrangements.

20. Intention Is Critical

Courts will not necessarily treat every document titled:

“Novation Agreement”

as a novation.

The court may examine:

wording;

contractual structure;

communications;

conduct;

payment arrangements;

surrounding circumstances;

whether the original party was released;

whether the new party accepted the obligations.

Therefore:

The substance of the transaction matters more than the label alone.

21. Case Law 1 — National Bonds Corporation PJSC v Taaleem PJSC & Deyaar Development PJSC [2011] DIFC CA 001

This is one of the most important UAE-related novation cases.

The dispute concerned the Sky Gardens transaction.

Taaleem had financing obligations to National Bonds Corporation, while Deyaar became involved in the transfer of Taaleem's interest and obligations.

The DIFC Court of Appeal considered the alleged novation and concluded that the transactional context indicated an intention to substitute Deyaar for Taaleem. (DIFC Courts)

The court also analysed the governing law of the novation and concluded that DIFC law was the proper law in the circumstances.

Importance

The case demonstrates:

A novation must be examined in the context of the entire transaction, including the parties' conduct and surrounding agreements.

Status: DIFC Court of Appeal authority, not a binding mainland UAE Court of Cassation precedent.

22. Case Law 2 — Taaleem PJSC v National Bonds Corporation & Deyaar Development PJSC [2010] DIFC CFI 014

The Court of First Instance considered whether Deyaar had assumed Taaleem's rights and obligations through a novation or assignment.

The dispute involved more than AED 200 million of financing.

The court examined:

contractual documents;

parties' conduct;

alleged transfer;

assumption of repayment obligations;

relationship between the original and new parties. (DIFC Courts)

Importance

It demonstrates that courts must determine:

Was there actually a concluded agreement to substitute the parties?

rather than simply assuming that commercial discussions produced a novation.

Status: DIFC authority.

23. Case Law 3 — Deyaar Development PJSC v Taaleem PJSC & National Bonds Corporation PJSC [2015] DIFC CA 010

The Court of Appeal dealt directly with the question whether Deyaar had assumed Taaleem's liabilities through novation.

The court concluded that:

through novation, Deyaar assumed Taaleem's liabilities and obligations to National Bonds Corporation.

The court considered the parties' communications and conduct as evidence of common intention. (DIFC Courts)

Importance

This is particularly useful for the principle:

Novation requires a genuine substitution of obligations, demonstrated by the parties' agreement and intention.

24. Case Law 4 — Parking District Solutions LLC v Ritz-Carlton Hotel Company Ltd & Hospitality Management Ltd [2022] DIFC CFI 002

This case provides a particularly clear distinction between assignment and novation.

A document called a “Novation Agreement” purported to transfer rights, obligations and liabilities from one entity to another.

But the original contracting party and the relevant hotel entities were not parties to that document.

The court held that the transfer could not bind them as an assignment and could not operate as a novation without the necessary participation/consent of the relevant party. (DIFC Courts)

Importance

The principle is:

A unilateral document between assignor and incoming party cannot automatically create a novation binding on the original counterparty.

Status: DIFC authority.

25. Case Law 5 — DIFC Investments Ltd v Dubai Islamic Bank [2022] DIFC CFI 024

This case involved a construction contract containing an express restriction against:

assignment;

transfer;

novation.

The court examined the effect of the contractual restriction and distinguished between:

assignment of rights;

transfer of obligations;

contractual restrictions on assignment;

law governing the assignment. (DIFC Courts)

The court also observed that where the law of the assignment differs from the law governing the underlying rights, different legal questions may be governed by different laws.

Importance

This is particularly valuable for multinational UAE transactions:

The law governing the assignment and the law governing the underlying right may not necessarily be identical.

Status: DIFC authority.

26. Case Law 6 — Lakhan v Lamia [2021] DIFC CA 001

A subcontractor, contractor and developer entered into a novation agreement.

The novation changed the identity of the contractual parties and also introduced a dispute-resolution provision referring disputes to the Dubai Courts.

A jurisdictional dispute subsequently arose between the Dubai Courts and DIFC Courts. (DIFC Courts)

Importance

This case demonstrates that a novation can affect not only:

payment obligations;

performance obligations;

but also:

arbitration clauses;

jurisdiction clauses;

dispute-resolution mechanisms.

Status: DIFC Court of Appeal authority.

27. Case Law 7 — Mibot v Mfast, DIFC ARB 035/2020

The case involved a construction-related contract originally between Mfast and Mosla.

Mosla, Mibot and Mfast subsequently entered into a novation agreement under which Mosla transferred its interest and obligations to Mibot.

The dispute concerned the interaction between the original arbitration clause and the later dispute-resolution provision in the novation agreement. (DIFC Courts)

Importance

It illustrates that:

A novation can change the procedural architecture of a contractual relationship.

Parties should therefore expressly address whether:

the old arbitration clause survives;

the new dispute clause replaces it;

disputes arising before novation remain subject to the old clause.

Status: DIFC arbitration authority.

28. Case Law 8 — Michael George Forbes v Robert Kidd [2025] DIFC CFI 081

The case concerned a deed of assignment and questions concerning whether the assignment satisfied the applicable formal requirements under UAE law.

The court recorded expert evidence that the assignment met the relevant UAE-law formal requirements. (DIFC Courts)

Importance

The case demonstrates the importance of:

documentary form;

execution;

proof;

authenticity;

evidence concerning assignment.

Status: DIFC authority.

29. Case Law 9 — Normand v Nathaniel [2024] DIFC SCT 125

The DIFC Small Claims Tribunal discussed privity of contract and the possibility that a person who was not an original contracting party could obtain rights through mechanisms such as assignment or subrogation.

The court recognised that assignment may place a claimant in the position of the original creditor. (DIFC Courts)

Importance

The case demonstrates the connection between:

Privity → Assignment → Standing to sue.

Status: DIFC authority.

30. Case-Law Revision Table

Important qualification: Most of the detailed reported UAE authorities on novation and assignment located here are DIFC cases. DIFC law is a distinct legal regime and these decisions should not be presented as binding mainland UAE precedents.

31. Assignment of Rights vs Assignment of Debt

This distinction is essential for examinations.

Assignment of right

B → C

B transfers the right to receive money from A.

A remains debtor.

Assignment of debt

A → C

C replaces A as debtor to B.

The creditor must consent under Article 418.

Novation

A + B + C

agree to replace the original relationship with a new one.

32. Effect on Guarantees

Suppose:

A owes B.

D guarantees A's debt.

A's debt is transferred to C.

Under Article 421, the debt's securities generally remain, but a personal or real guarantor is not bound to the creditor after the debt assignment unless the guarantor consents. (UAE Legislation)

This protects the guarantor from being exposed to a different debtor without consent.

33. Assignment of Contract vs Assignment of Right

These should not be confused.

Assignment of right

Only a particular claim is transferred.

Example:

Right to receive AED 5 million.

Transfer/assignment of entire contract

The transaction may involve:

rights;

obligations;

liabilities;

warranties;

termination rights.

Where both rights and obligations are transferred and the original party is released, the transaction may constitute a novation, depending on the applicable law and parties' intention.

34. Example — Construction Contract

Original arrangement:

Developer A → Contractor B

B has:

right to payment;

obligation to construct.

B wants C to replace it completely.

Mere assignment

B transfers its right to receive payment to C.

But B may remain responsible for construction.

Novation

A, B and C agree:

C replaces B;

C assumes B's obligations;

A accepts C;

B is released.

That is a classic novation structure.

35. Example — Bank Loan

Original

Borrower A → Bank B

A owes AED 10 million.

Debt assignment

A wants C to assume the debt.

B must consent under Article 418.

Novation

A, B and C enter into a replacement financing arrangement.

The original debt is replaced by a new obligation.

The documentation should clearly state:

whether the old debt is discharged;

whether securities survive;

whether guarantees survive;

whether interest is carried forward;

whether defaults under the old agreement remain relevant.

36. Assignment and Notice

Under Article 407, notice is extremely important.

Suppose:

B assigns A's debt to C.

A has not received notice.

A pays B.

The legal consequences may depend upon the statutory requirements concerning enforceability and the timing of notice.

Therefore, after assignment, the assignee should ensure:

Prompt and provable notice to the debtor.

37. Assignment and Contractual Prohibition

Suppose a contract states:

“No assignment without prior written consent.”

B assigns its rights to C without consent.

The parties must examine:

wording of the prohibition;

whether it covers rights, obligations or the entire contract;

whether the restriction is legally effective;

consequences between assignor and assignee;

consequences against the debtor.

The DIFC Investments v DIB case is useful for illustrating the importance of express contractual restrictions. (DIFC Courts)

38. Novation and Existing Securities

A major drafting issue is:

What happens to guarantees, mortgages and other securities after novation?

Parties should expressly state whether:

security survives;

security is released;

new security is granted;

guarantor consents;

mortgage remains effective;

indemnities continue.

The current UAE statutory rules concerning debt assignment make this especially important.

39. Novation and Dispute-Resolution Clauses

A novation can create an unexpected problem.

Original contract:

DIFC-LCIA arbitration.

Novation agreement:

Dubai Courts exclusive jurisdiction.

Which clause applies?

The answer requires analysis of:

wording;

scope;

whether the novation expressly replaces the old clause;

whether the arbitration agreement was separately incorporated;

applicable arbitration law.

Lakhan v Lamia demonstrates precisely how a novation can generate a dispute over the continuing effect of an arbitration clause. (DIFC Courts)

40. Novation and Governing Law

The law governing the original contract may not automatically answer every question about a later transfer.

In National Bonds v Taaleem, the DIFC Court examined the transactional context in determining the proper law of the novation. (DIFC Courts)

Similarly, DIFC Investments v DIB illustrates that different legal questions concerning assignment can potentially be connected to different legal systems. (DIFC Courts)

Therefore, multinational transactions should separately identify:

law of original contract;

law governing assignment/novation;

law governing underlying right;

procedural law;

law governing enforcement.

41. Novation and Release of Original Debtor

One of the most important consequences of novation is possible release of the original party.

Example:

A owes B.

C substitutes for A.

If B agrees to release A:

A — released

C → B

The creditor now looks to C according to the new arrangement.

This is different from a simple arrangement where C merely promises A:

“I will pay your debt for you.”

In the latter situation, A may remain liable unless the creditor has agreed to substitution.

42. Assignment Does Not Necessarily Release the Assignor

Suppose:

A contracts with B.

A assigns its rights to C.

That does not automatically mean that all of A's contractual obligations disappear.

This is why:

Assignment of rights ≠ transfer of entire contractual position.

Where the intention is to replace the entire contractual party, novation or another legally recognised mechanism may be necessary.

43. Relationship With Privity

Privity means that contractual rights and obligations generally operate between the relevant contracting parties.

Assignment provides a legally recognised mechanism for transferring rights despite the original contractual relationship.

Therefore:

Privity

↓

Assignment

↓

New holder of right

The assignee can acquire the assigned right subject to applicable legal conditions.

The principle was illustrated in Normand v Nathaniel, where the DIFC Court discussed assignment as a possible basis for a claimant standing in the shoes of the original creditor. (DIFC Courts)

44. Assignment and Subrogation

Assignment and subrogation can produce similar practical outcomes but are conceptually different.

Assignment

A right is transferred.

Subrogation

A person who has made payment or otherwise satisfies the relevant legal conditions may acquire rights by operation of law or agreement.

For example:

Insurer pays insured

↓

Insurer may become entitled to pursue the responsible party through subrogation.

Therefore:

Assignment = transfer mechanism

Subrogation = substitution of legal position arising under its own rules

45. Assignment and Insolvency

Assignment is particularly significant in insolvency.

A company may assign:

receivables;

financing rights;

contractual claims.

But insolvency law may impose additional restrictions concerning:

fraudulent transfers;

preferences;

creditor protection;

attachment;

insolvency estate;

avoidance.

Thus, a civil-law assignment must always be examined alongside applicable special legislation.

46. Practical Drafting Checklist

A UAE assignment agreement should clearly identify:

1. Original parties

Who is assignor?

Who is debtor?

2. Assignee

Who receives the right?

3. Assigned right

Exactly what claim is transferred?

4. Consideration

Is the assignment paid or gratuitous?

5. Restrictions

Does the underlying contract prohibit assignment?

6. Notice

Has the debtor been notified?

7. Effective date

When does the assignment operate?

8. Defences

What defences remain available?

9. Security

What happens to guarantees and collateral?

10. Governing law

Which law governs the assignment?

11. Jurisdiction

Which court/arbitration mechanism applies?

47. Novation Drafting Checklist

A proper novation agreement should expressly state:

identity of outgoing party;

identity of incoming party;

identity of continuing party;

old agreement;

new agreement;

obligations assumed;

obligations discharged;

release of outgoing party;

treatment of accrued liabilities;

treatment of existing breaches;

guarantees;

mortgages;

security;

indemnities;

dispute-resolution clause;

governing law;

effective date.

This reduces the risk that a court will characterise the document as merely an assignment rather than a novation.

48. Common Mistakes

Mistake 1

Calling every transfer a novation.

Correction: Determine whether the original obligation was actually replaced.

Mistake 2

Assuming debtor consent is always required for assignment of a right.

Correction: Current Article 405 does not make debtor consent a general condition of validity, although Article 407 addresses enforceability. (UAE Legislation)

Mistake 3

Assuming debt can be transferred without creditor consent.

Correction: Article 418 requires creditor consent. (UAE Legislation)

Mistake 4

Assuming guarantees automatically survive every debt transfer.

Correction: Article 421 specifically protects guarantors by requiring their consent for continuing liability. (UAE Legislation)

Mistake 5

Ignoring the dispute-resolution clause.

Correction: A novation can change the jurisdiction or arbitration framework, as illustrated by Lakhan v Lamia. (DIFC Courts)

49. Comparison Table

50. Examination Formula

Use:

R–C–N–S–E–G

R — Right or debt?

First determine what is being transferred.

C — Consent

Whose consent is legally required?

N — Notice

Has the debtor been notified where required?

S — Substitution

Has the original obligation actually been replaced?

E — Effect

What happens to securities, guarantees and accrued liabilities?

G — Governing law

Which law governs the transfer and the underlying obligation?

51. Quick Revision Points

Assignment of right

Creditor → Assignee

Current Article 405 permits assignment unless prohibited by law, agreement or the nature of the obligation. (UAE Legislation)

Enforceability

Notice or debtor acceptance

Article 407 governs enforceability against the debtor and third parties. (UAE Legislation)

Assignment of debt

Original debtor → New debtor

Article 418 requires consent of the assignee and creditor. (UAE Legislation)

Effect of acceptance

Creditor's acceptance can discharge original debtor and transfer liability to assignee. (UAE Legislation)

Guarantees

Guarantor does not remain bound after debt assignment without consent. (UAE Legislation)

Novation

Old obligation → New obligation

The essential issue is genuine substitution and the parties' intention.

Key case

Deyaar v Taaleem [2015] — novation resulted in Deyaar assuming Taaleem's liabilities and obligations to NBC. (DIFC Courts)

Conclusion

The UAE law of novation and assignment is based on an important distinction between transferring a right, transferring a debt, and replacing an existing obligation.

The current Civil Transactions Law provides a detailed statutory framework for assignment:

Articles 405–417 → Assignment of Rights

Articles 418–424 → Assignment of Debt (UAE Legislation)

The key distinction is:

Assignment transfers a legal position; novation substitutes a legal relationship.

For a right:

Creditor → Assignee

For a debt:

Original Debtor → New Debtor

For novation:

Old Contract/Obligation → New Contract/Obligation

The leading UAE-related authorities such as National Bonds v Taaleem, Taaleem v NBC & Deyaar, Deyaar v Taaleem, Parking District v Ritz-Carlton, DIFC Investments v DIB, Lakhan v Lamia, Mibot v Mfast, and Forbes v Kidd demonstrate the importance of consent, intention, notice, contractual restrictions, governing law, securities and dispute-resolution clauses.

For current practice, the 2025 Civil Transactions Law effective from 1 June 2026 should be treated as the primary statutory framework; older cases and former 1985-law provisions should be used carefully as historical authorities rather than automatically treated as statements of the current article numbering. (UAE Legislation)
