M&A Dispute in Turkey After Closing: 20 Claims Foreign Buyers Should Consider in 2026

Discover 20 legal claims foreign buyers should consider after a Turkish M&A dispute, including warranty breaches, hidden debts, fraud, indemnity, price adjustment, and urgent remedies.

An M&A transaction does not always end when the purchase price is paid and the shares are transferred. Foreign buyers may later discover hidden debts, inaccurate financial statements, undisclosed litigation, tax liabilities, employee claims, missing assets, related-party transactions, or breaches of the share purchase agreement.

In 2026, post-closing M&A disputes in Turkey frequently involve digital records, cloud accounting systems, online banking, electronic signatures, remote management, customer data, and cross-border enforcement. The buyer should identify the legal and contractual remedies quickly because SPAs commonly contain notice requirements, liability caps, claim periods, arbitration clauses, and specific procedures.

The following 20 claims may be considered depending on the transaction documents and the evidence.

1. Breach of Representations and Warranties

The buyer may claim compensation when a seller’s representation or warranty proves to be false or incomplete. Common warranties concern ownership, financial statements, liabilities, taxes, employees, contracts, litigation, assets, intellectual property, and regulatory compliance.

The buyer should compare the warranty wording with the company’s actual position at signing and closing.

2. Indemnity for Hidden Liabilities

An indemnity claim may arise when the SPA requires the seller to compensate the buyer for specifically identified risks. Examples include tax assessments, employee claims, environmental liabilities, regulatory fines, litigation, or liabilities created before closing.

The buyer should check the indemnity scope, claim notice procedure, financial limits, deductible, and survival period.

3. Fraudulent Misrepresentation

If the seller intentionally provides false information to persuade the foreign buyer to complete the acquisition, the buyer may evaluate fraud or fraudulent misrepresentation claims.

Inflated revenue, concealed bank debt, hidden investigations, false customer figures, and fabricated contracts may be relevant if the buyer relied on them when deciding to invest.

4. Concealment of Material Information

A seller may face liability for deliberately concealing information that should reasonably have been disclosed. This may include pending lawsuits, enforcement proceedings, insolvency risks, related-party transactions, employee disputes, or the loss of a major customer.

The buyer should establish that the concealed information was material and affected the transaction or purchase price.

5. Purchase Price Adjustment Claim

Many SPAs allow the purchase price to be recalculated after closing based on actual debt, cash, working capital, revenue, or other financial information.

If the seller overstates the company’s financial position, the buyer may seek a downward price adjustment. Accounting records, closing accounts, expert reports, and transaction formulas may be decisive.

6. Working Capital or Net Debt Dispute

A disagreement may arise over whether certain liabilities should be included in net debt or whether the company had the agreed level of working capital at closing.

The buyer should examine unpaid invoices, shareholder loans, deferred taxes, guarantees, customer advances, inventory valuation, and unusual payments made before closing.

7. Earn-Out Dispute

Where part of the purchase price depends on future revenue, profit, customer retention, or another performance target, the buyer may challenge the seller’s calculation or conduct.

The seller may also claim that the buyer manipulated the business after closing to avoid paying the earn-out. The parties should review the calculation method, accounting policies, management obligations, and access to financial records.

8. Failure to Transfer Shares or Corporate Control

A claim may arise if the seller fails to transfer the agreed shares, voting rights, management authority, bank signatory powers, corporate records, licenses, or operational control.

The buyer may consider specific performance, recognition of shareholder rights, compensation, refund, or contractual penalties depending on the transaction documents.

9. Failure to Complete Closing Obligations

Post-closing obligations may include delivery of books and records, resignation of directors, appointment of new managers, transfer of passwords, assistance with licenses, customer introductions, bank changes, and execution of additional documents.

Failure to complete these obligations may support a contractual claim even if the shares were formally transferred.

10. Rescission or Termination of the Acquisition

In serious cases, the foreign buyer may consider rescission, avoidance, or termination of the acquisition. This may be relevant where the transaction was affected by fraud, fundamental breach, invalid consent, lack of authority, or material non-performance.

Rescission is not automatic after closing. The buyer should assess whether the parties can realistically return the shares, purchase price, assets, dividends, and other benefits received.

11. Damages for Lost Profits and Goodwill

The buyer may claim damages for losses caused by the seller’s breach, including lost profits, loss of goodwill, customer losses, emergency management costs, and reduction in the value of the acquired company.

The buyer must generally establish causation and calculate the loss with reliable financial evidence. A decline in business performance alone may not prove seller liability.

12. Breach of a Non-Compete Clause

If the seller establishes, manages, finances, or advises a competing business in violation of the SPA, the buyer may seek compensation, contractual penalties, and potentially an injunction.

The scope, territory, duration, and commercial activity covered by the clause should be reviewed carefully. A broad restriction may be challenged if it is not reasonably connected to the goodwill and business interests transferred.

13. Customer and Employee Non-Solicitation Claim

The buyer may have a claim if the seller deliberately recruits key employees, approaches protected customers, or diverts business relationships after closing.

Customer and employee movement is not automatically unlawful. The buyer should show a contractual restriction, misuse of confidential information, targeted solicitation, or coordinated diversion.

14. Confidentiality and Trade Secret Misuse

A seller may breach confidentiality obligations by using customer lists, pricing data, formulas, technical documents, software, business strategies, or other protected information in a new business.

The buyer may seek damages, injunctive relief, evidence preservation, and protection against continuing use of confidential information.

15. Unfair Competition and Business Opportunity Diversion

The buyer may consider an unfair competition claim where the seller intentionally creates confusion, copies the acquired company’s business identity, diverts contracts, misleads customers, or takes opportunities that belonged to the acquired business.

The buyer should distinguish ordinary market competition from conduct designed to exploit the goodwill and information purchased in the transaction.

16. Hidden Tax Liabilities

Tax risks are among the most common post-closing M&A problems. The company may later receive assessments relating to periods before closing, undeclared transactions, payroll taxes, withholding, customs obligations, or incorrect deductions.

The buyer should examine whether the SPA includes a tax indemnity and whether the seller provided accurate tax warranties. The economic impact may justify an indemnity or price adjustment claim.

17. Undisclosed Employee and Labor Claims

The acquired company may face claims for unpaid wages, overtime, severance, annual leave, bonuses, workplace accidents, discrimination, or unlawful termination.

If the seller failed to disclose known employee disputes or misrepresented payroll liabilities, the buyer may consider warranty and indemnity claims. Employment records and payroll data should be reviewed promptly.

18. Undisclosed Litigation, Criminal Investigations, or Enforcement Proceedings

A buyer may discover a pending civil lawsuit, criminal investigation, regulatory inquiry, enforcement file, asset restriction, or search and seizure procedure after closing.

The legal consequences depend on when the matter began, whether the seller knew about it, whether it was disclosed, and how it affects the company’s value or operations. A buyer may consider indemnity, damages, price reduction, or rescission in serious circumstances.

19. Hidden Debt, Guarantees, Pledges, or Related-Party Asset Transfers

The seller may have concealed bank loans, guarantees, security interests, shareholder loans, or transfers of company assets to related parties.

If company money, contracts, inventory, real estate, or receivables were transferred without commercial justification, the buyer may examine claims against the seller, directors, related companies, or other responsible persons.

The buyer may also consider urgent measures to preserve assets and prevent further transfers.

20. Regulatory, License, Intellectual Property, and Compliance Breaches

A company may operate without the required permits, licenses, approvals, intellectual property rights, data compliance, environmental compliance, or sector-specific authorizations.

If the seller represented that the company was fully compliant but the statement was materially false, the buyer may assess warranty, indemnity, damages, or termination claims. The practical remedy will depend on whether the problem can be corrected after closing.

Urgent Remedies After Discovering an M&A Breach

The buyer should preserve the SPA, due diligence files, data room records, financial statements, emails, messages, board minutes, bank records, tax documents, employee files, and all communications with the seller.

Where assets or evidence are at risk, the buyer may consider an interim injunction, evidence-preservation measure, or precautionary attachment for a monetary claim. The requested remedy should be specific and proportionate, and the court may require security.

The buyer should also send a formal notice in accordance with the SPA. A defective or late notice may create avoidable difficulties, particularly where the contract contains a short claim period or mandatory pre-litigation procedure.

2026 Practical Considerations for Foreign Buyers

Foreign buyers should examine electronic closing records, cloud accounting, online banking, digital signatures, data room access logs, customer databases, remote employee communications, and electronic corporate records.

The buyer should not unlawfully access private accounts or company systems. Digital evidence must be preserved and collected lawfully.

The governing law, jurisdiction, arbitration clause, translation requirements, power of attorney, service procedures, and location of the seller’s assets should also be reviewed before starting proceedings.
