Civil Law and UAE: M&A Post-Closing Disputes

1. Introduction

M&A post-closing disputes are disputes that arise after an acquisition, merger, share purchase, business transfer, or similar transaction has formally closed.

Closing does not necessarily end the parties' legal relationship. Important obligations may continue after closing, including:

• payment of deferred consideration;
• earn-outs;
• representations and warranties;
• indemnities;
• tax obligations;
• escrow arrangements;
• working-capital adjustments;
• completion accounts;
• non-compete obligations;
• confidentiality;
• transition services;
• disclosure obligations;
• fraud claims;
• warranty claims;
• contingent liabilities;
• regulatory obligations.

In the UAE, post-closing M&A disputes may involve mainland UAE law, DIFC or ADGM law, arbitration, contractual choice of law, corporate legislation and general civil-law principles.

A useful framework is:

M&A Post-Closing Dispute = Contract + Corporate Law + Evidence + Causation + Damages + Dispute Resolution + Enforcement

2. Meaning of Closing

"Closing" is the point at which the transaction's agreed completion conditions are satisfied and the agreed acquisition steps occur.

Typical closing events include:

1. purchase price payment;
2. transfer of shares;
3. transfer of control;
4. delivery of corporate documents;
5. resignation/appointment of directors;
6. release of escrow;
7. completion of regulatory requirements.

However:

Closing is a transaction milestone, not necessarily the end of contractual obligations.

This is the foundation of post-closing disputes.

3. UAE Legal Framework

The precise legal framework depends on the transaction.

Important sources may include:

A. UAE Civil Transactions Law

Relevant to:

• contractual obligations;
• good faith;
• interpretation;
• damages;
• causation;
• compensation;
• abuse of rights.

B. UAE Commercial Companies Law

Federal Decree-Law No. 32 of 2021 is relevant to:

• companies;
• shareholders;
• directors;
• corporate restructuring;
• share transfers;
• corporate authority;
• governance.

C. UAE Arbitration Law

Federal Law No. 6 of 2018 applies where the parties have agreed to arbitration.

D. Evidence Law

Federal Decree-Law No. 35 of 2022 is important for:

• documents;
• electronic evidence;
• expert evidence;
• evidentiary burdens.

E. Civil Procedure Law

Federal Decree-Law No. 42 of 2022 governs relevant procedural matters before UAE courts.

F. DIFC and ADGM frameworks

Where the transaction falls within those jurisdictions, their separate corporate, contractual and procedural rules may apply.

4. Major Types of Post-Closing M&A Disputes

4.1 Purchase Price Disputes

The buyer and seller may disagree about the final purchase price.

Common mechanisms include:

• completion accounts;
• working-capital adjustments;
• net-debt adjustments;
• cash adjustments;
• locked-box mechanisms;
• earn-outs.

Example:

The preliminary price is AED 500 million.

After closing, the buyer calculates net debt at AED 80 million, while the seller claims it was only AED 40 million.

The parties therefore dispute the final consideration.

5. Completion Accounts Disputes

Completion accounts are prepared to determine the company's financial position at closing.

Typical disputed items include:

• cash;
• debt;
• working capital;
• provisions;
• inventory;
• receivables;
• tax liabilities.

The dispute may turn on:

• accounting standards;
• contractual definitions;
• historical accounting practices;
• accounting policies;
• expert determination clauses.

Therefore, the court or arbitral tribunal must often interpret both the contract and accounting evidence.

6. Earn-Out Disputes

An earn-out makes part of the purchase price dependent on future performance.

For example:

Buyer pays AED 300 million at closing plus AED 100 million if EBITDA reaches an agreed level during the following two years.

Disputes can arise if the buyer:

• changes accounting policies;
• reallocates expenses;
• restructures the business;
• transfers customers;
• changes management;
• integrates the target with another company.

The seller may argue that the buyer deliberately reduced the target's apparent performance to avoid paying the earn-out.

7. Warranty Claims

Representations and warranties are among the most important sources of post-closing litigation.

A seller may have warranted that:

• financial statements were accurate;
• there was no undisclosed litigation;
• taxes had been properly paid;
• intellectual property was owned;
• material contracts were valid;
• the company complied with applicable laws;
• no material adverse event had occurred.

After closing, the buyer may discover that one or more statements were inaccurate.

The central questions become:

1. Was the warranty actually given?
2. Was it false?
3. When was it false?
4. Was the buyer aware of the issue?
5. Did the contract restrict the claim?
6. Did the breach cause recoverable damage?

8. Indemnity Disputes

An indemnity is usually more specific than a general warranty.

For example:

Seller indemnifies Buyer against losses arising from a pre-closing tax liability.

The dispute may concern:

• whether the liability falls within the indemnity;
• whether it arose before closing;
• whether the buyer suffered an actual loss;
• whether notice was properly given;
• whether the indemnity has a cap;
• whether exclusions apply.

Contract wording is therefore crucial.

9. Fraud and Misrepresentation

Fraud can create particularly serious post-closing disputes.

Examples include:

• falsified financial statements;
• concealed liabilities;
• undisclosed related-party transactions;
• fabricated contracts;
• hidden regulatory investigations;
• manipulated revenue;
• undisclosed litigation.

A buyer may seek:

• damages;
• rescission where legally available;
• indemnification;
• contractual remedies;
• other appropriate relief.

Fraud may also affect contractual limitations and evidentiary questions.

10. Disclosure and Due Diligence

A frequent dispute is:

"The buyer should have discovered this problem during due diligence."

The seller may argue:

"The information was disclosed."

The buyer may respond:

"The information was incomplete, misleading or insufficient to reveal the actual problem."

Courts and tribunals may examine:

• disclosure letters;
• data-room documents;
• emails;
• management presentations;
• due-diligence reports;
• financial statements;
• legal opinions;
• expert evidence.

The distinction between knowledge, disclosure and contractual protection becomes particularly important.

11. Sandbagging and Anti-Sandbagging

An M&A agreement may address whether a buyer can claim for a breach that it knew about before closing.

Sandbagging

Buyer knows about a warranty problem but closes anyway and later makes a claim.

Anti-sandbagging

Contract prevents the buyer from claiming where it had actual knowledge before closing.

UAE courts or tribunals would generally need to examine the actual contractual wording and applicable law.

This is an excellent example of why careful drafting matters.

12. Leakage Disputes

In a locked-box transaction, the purchase price may be based on a historical balance sheet.

The seller may agree that no value will be extracted from the target between the locked-box date and closing except for permitted leakage.

Disputes may concern:

• dividends;
• management fees;
• related-party payments;
• bonuses;
• asset transfers;
• transaction expenses.

The buyer may claim that prohibited leakage occurred.

13. Material Adverse Change

M&A agreements may contain provisions dealing with material adverse changes or events.

Post-closing disputes may arise where:

• revenues fall;
• regulatory restrictions arise;
• a major customer leaves;
• litigation emerges;
• a market crisis occurs;
• a business loses a key licence.

The interpretation depends heavily on the precise transaction agreement.

14. Post-Closing Covenants

Obligations may survive closing.

Examples include:

• non-compete;
• non-solicitation;
• confidentiality;
• transition assistance;
• intellectual-property cooperation;
• regulatory cooperation;
• employee matters;
• records preservation.

A breach can produce a separate post-closing claim.

15. Directors and Management Liability

After an acquisition, disputes may concern conduct of:

• former directors;
• continuing directors;
• sellers' representatives;
• buyer-appointed management.

Potential allegations include:

• breach of fiduciary duties where applicable;
• misuse of corporate assets;
• unauthorised transactions;
• conflicts of interest;
• related-party transactions;
• disclosure failures.

Corporate-law analysis must be separated from contractual warranty claims.

16. Shareholder and Corporate Authority Issues

M&A disputes can also arise from questions concerning:

• authority to sell shares;
• shareholder approvals;
• board resolutions;
• powers of attorney;
• transfer restrictions;
• beneficial ownership;
• registration requirements.

A party may argue that the transaction or a particular post-closing act lacked proper corporate authority.

17. Good Faith

Good faith is particularly relevant to continuing contractual obligations.

Suppose an acquisition agreement requires the buyer to operate the target in a manner relevant to an earn-out.

If the buyer intentionally restructures the business solely to defeat the seller's earn-out entitlement, questions of contractual interpretation and good faith may arise.

Good faith does not automatically rewrite a contract.

Rather, the court must examine:

• the contractual language;
• the parties' obligations;
• the nature of the conduct;
• applicable mandatory law.

18. Causation and Damages

A warranty breach does not automatically determine the amount of compensation.

The buyer generally needs to establish:

Breach → Causation → Recoverable Loss

For example:

A seller warrants that a subsidiary has no material tax liability.

After closing, the buyer discovers a pre-closing tax liability of AED 30 million.

The buyer must establish:

• the warranty;
• its breach;
• the relevant liability;
• causal connection;
• recoverable damage;
• compliance with contractual claim procedures.

19. Limitation of Liability

M&A agreements commonly contain:

• liability caps;
• baskets;
• de minimis thresholds;
• time limits;
• exclusions;
• exclusive-remedy clauses.

Example:

General warranty claims capped at 20% of purchase price.

The buyer may nevertheless argue that a particular claim falls outside the cap, for example because of:

• fraud;
• fundamental warranties;
• title warranties;
• specific indemnities.

The answer depends on the contract and governing law.

20. De Minimis and Basket Provisions

A de minimis provision may provide that individual claims below a particular threshold cannot be pursued.

A basket may require aggregate losses to exceed a threshold before recovery begins.

Example:

• individual threshold: AED 100,000;
• basket: AED 5 million;
• liability cap: AED 50 million.

These provisions can generate substantial post-closing disputes over calculation.

21. Notice Requirements

M&A agreements often require the buyer to notify the seller of claims within a particular period.

Disputes may arise concerning:

• when the buyer became aware;
• whether notice was timely;
• whether the notice contained sufficient information;
• whether defective notice bars the claim;
• whether the contractual notice provision is a condition precedent.

Therefore, claim administration after closing can be as important as the underlying substantive claim.

22. Arbitration and M&A Disputes

Large UAE M&A transactions frequently include arbitration clauses.

A post-closing dispute may therefore involve:

1. arbitration agreement;
2. seat;
3. governing law;
4. tribunal jurisdiction;
5. interim measures;
6. document production;
7. expert evidence;
8. damages;
9. award enforcement.

The UAE Arbitration Law provides the principal statutory framework for UAE-seated arbitration.

23. Evidence in M&A Disputes

Evidence can include:

• SPA;
• disclosure letter;
• data-room documents;
• board minutes;
• shareholder resolutions;
• financial statements;
• audit reports;
• emails;
• WhatsApp messages;
• expert reports;
• accounting records;
• electronic signatures;
• transaction databases.

Electronic evidence is increasingly important in proving what the parties knew before closing.

24. Expert Evidence

M&A disputes often require experts.

Accounting experts

For:

• working capital;
• net debt;
• earn-outs;
• valuation.

Tax experts

For:

• historical tax liabilities;
• tax indemnities.

Industry experts

For:

• market assumptions;
• regulatory standards.

Valuation experts

For:

• diminution in value;
• lost profits;
• enterprise value.

The court or tribunal ultimately determines the legal issues, while experts assist with technical matters.

25. Valuation of Warranty Claims

Several valuation approaches may arise.

A. Diminution in value

Difference between:

Actual value of company − value company would have had if warranty were true

B. Direct loss

Actual costs incurred because of the breach.

C. Indemnified loss

Loss specifically falling within an indemnity.

D. Remedial costs

Reasonable expenditure necessary to correct the problem.

The appropriate measure depends upon the agreement and applicable law.

26. Six+ Important Case Authorities

Because UAE M&A post-closing litigation is highly fact-specific, there is not a single universally applicable UAE "M&A post-closing disputes" doctrine. The following cases are therefore useful directly or by analogy, particularly for contractual interpretation, financial obligations, electronic evidence, good faith and cross-border enforcement.

1. Credit Suisse (Switzerland) Ltd v Ashok Kumar Goel & Others [2020] DIFC CFI 066

This DIFC decision is relevant to contractual interpretation in sophisticated commercial relationships.

M&A relevance

Post-closing disputes usually depend on interpreting:

• SPA definitions;
• warranties;
• indemnities;
• conditions;
• notice provisions;
• liability limitations.

The case illustrates the importance of construing the parties' contractual arrangement before determining liability.

2. ICICI Bank Ltd v Bavaguthu Raghuram Shetty [2022] DIFC CFI 034

This DIFC case is relevant to electronic transactions, contractual documents and attribution.

M&A relevance

Modern acquisitions involve enormous electronic records. Questions concerning:

• electronic signatures;
• authority;
• emails;
• digital records;

can become central to proving what was agreed before closing.

3. GFH Capital Ltd v David Lawrence Haigh [2014] DIFC CFI 020

This DIFC authority is relevant to electronic communications, authority and contractual evidence.

M&A relevance

It demonstrates why emails and electronic instructions can become important evidence concerning:

• authority;
• transaction negotiations;
• representations;
• post-closing instructions.

4. DNB Bank ASA v Gulf Eyadah Corporation & Gulf Navigation Holding PJSC

This cross-border UAE/DIFC litigation is an important authority concerning recognition and enforcement of foreign arbitral awards.

M&A relevance

Large M&A transactions frequently involve arbitration and cross-border enforcement.

The case demonstrates the importance of:

• jurisdiction;
• arbitration;
• enforcement;
• interaction between different UAE jurisdictions.

It is not itself a conventional SPA warranty case, so its relevance is primarily procedural and cross-border.

5. NMC Healthcare Ltd v Dubai Islamic Bank PJSC

This is relevant to sophisticated financial and commercial disputes involving contractual and documentary issues.

M&A relevance

It illustrates the complexity that can arise when corporate transactions intersect with:

• financing;
• security;
• corporate obligations;
• financial documentation;
• multiple parties.

6. Access Group DWC LLC & Proex Partners Ltd v BLS International FZE [2023] DIFC CFI 091

This DIFC case is relevant to contractual performance and good faith.

M&A relevance

Post-closing parties may remain contractually interconnected through earn-outs, transition obligations and continuing covenants.

The case is useful for understanding why contractual rights must be considered alongside the parties' conduct.

7. Gulf Navigation Holding PJSC v DNB Bank ASA

This litigation is relevant to arbitration, contractual obligations and cross-border enforcement.

M&A relevance

It demonstrates the importance of properly structuring:

• dispute-resolution clauses;
• governing-law provisions;
• enforcement mechanisms.

These issues can become critical after closing when a dispute crosses jurisdictions.

8. Standard Chartered Bank v Investment Group Private Limited [2014] DIFC CFI 026

This DIFC case involved substantial financial obligations and contractual enforcement.

M&A relevance

It illustrates the importance of precise contractual obligations and enforcement mechanisms in sophisticated financial transactions, principles that frequently appear in acquisition financing and post-closing disputes.

27. Mainland UAE Case-Law Principles

In addition to the named DIFC authorities, Federal Supreme Court jurisprudence concerning the following principles is highly relevant to mainland UAE M&A disputes:

Contractual good faith

Courts consider contractual performance within the framework of good faith.

Contract interpretation

The court determines the legal meaning and effect of contractual provisions.

Causation and damages

Compensation requires legally established damage connected to the relevant breach.

Abuse of rights

A formally existing right cannot necessarily be exercised without regard to statutory restrictions on abuse.

Expert evidence

Accounting and valuation questions may require specialist evidence.

These principles should be applied together rather than treating any one of them as an automatic rule for every acquisition dispute.

28. M&A Post-Closing Dispute Timeline

A useful timeline is:

Signing

↓

Due diligence

↓

Disclosure

↓

Conditions precedent

↓

Closing

↓

Post-closing accounts

↓

Warranty/indemnity discovery

↓

Notice of claim

↓

Negotiation

↓

Expert determination / mediation

↓

Arbitration or litigation

↓

Judgment/award

↓

Enforcement

This illustrates why closing does not necessarily terminate the parties' legal relationship.

29. Buyer-Side Strategy

A buyer facing a post-closing dispute should generally:

1. review the SPA;
2. identify the relevant warranty or indemnity;
3. review disclosure materials;
4. establish when the breach was discovered;
5. preserve electronic evidence;
6. calculate loss;
7. comply with notice provisions;
8. check limitation periods;
9. examine liability caps;
10. assess arbitration/jurisdiction;
11. obtain accounting or valuation expertise where necessary.

30. Seller-Side Strategy

The seller should examine:

1. exact contractual wording;
2. disclosure;
3. buyer's pre-closing knowledge;
4. due-diligence materials;
5. notice compliance;
6. causation;
7. mitigation;
8. liability caps;
9. baskets and thresholds;
10. limitation periods;
11. exclusions;
12. fraud/fundamental-warranty exceptions.

31. Special Importance of Drafting

Many post-closing disputes can be reduced through careful SPA drafting.

Important provisions include:

• precise definitions;
• warranty schedules;
• disclosure standards;
• indemnities;
• claim procedures;
• time limits;
• liability caps;
• baskets;
• de minimis thresholds;
• fraud carve-outs;
• tax indemnities;
• earn-out methodology;
• accounting principles;
• expert determination;
• dispute-resolution clause;
• governing law;
• jurisdiction;
• arbitration;
• confidentiality.

32. M&A and UAE Legal Pluralism

UAE M&A transactions demonstrate the importance of understanding the distinction between:

Mainland transaction

Federal UAE legislation and applicable local procedures.

DIFC transaction

DIFC laws and DIFC Courts may apply depending on jurisdiction and contractual arrangements.

ADGM transaction

ADGM law and courts may apply.

International transaction

Foreign governing law and arbitration may become relevant.

Therefore:

The first question in a UAE M&A dispute is not simply "Who breached the contract?" It is also "Which legal framework governs the dispute?"

33. Important Examination Distinctions

Warranty vs Indemnity

Warranty: generally compensates for breach of contractual representation/warranty.

Indemnity: generally provides contractual protection against specified losses.

Pre-closing vs Post-closing liability

A liability may arise from pre-closing conduct but become discoverable after closing.

Contractual vs Corporate claim

A contractual SPA claim is not necessarily identical to a claim against directors or the company under corporate law.

Knowledge vs Disclosure

Knowing that a problem exists and receiving legally sufficient contractual disclosure are not always identical questions.

Loss vs Valuation

Proving that a warranty was breached does not automatically establish the amount recoverable.

34. Revision Table

35. Conclusion

UAE M&A post-closing disputes arise because the legal relationship created by an acquisition normally continues beyond the closing date.

The most important disputes concern:

• purchase-price adjustments;
• completion accounts;
• earn-outs;
• warranties;
• indemnities;
• disclosure;
• fraud;
• tax;
• leakage;
• post-closing covenants;
• valuation;
• corporate authority;
• causation and damages;
• arbitration and enforcement.

The central analytical sequence is:

SPA → Applicable Law → Contractual Obligation → Breach → Causation → Loss → Contractual Limitations → Remedy → Enforcement

The UAE's combination of civil-law principles, specialised free-zone jurisdictions, arbitration and sophisticated commercial regulation makes jurisdiction and contractual drafting particularly important.

Final Formula

UAE M&A Post-Closing Liability =
Contract + Corporate Law + Evidence + Breach + Causation + Damage + Contractual Limits + Dispute Resolution + Enforcement

The key practical lesson is that closing transfers the transaction; it does not necessarily extinguish the parties' continuing legal obligations.
