Mergers & Acquisitions in Turkey: Legal Due Diligence Checklist

1. Introduction: Why Legal Due Diligence Is Critical in Turkish M&A Transactions

Turkey has become an increasingly attractive market for foreign investors seeking growth through mergers and acquisitions (M&A). Strategic location, a large domestic market, and competitive operational costs make Turkish companies appealing acquisition targets.

However, company acquisition in Turkish law involves legal, regulatory, and structural risks that are often underestimated by foreign buyers. Unlike some jurisdictions where disclosures are standardized, in Turkey, hidden liabilities, compliance gaps, and shareholder-level risks may only surface through a properly conducted legal due diligence process.

This article provides a practical, transaction-oriented legal due diligence checklist for mergers and acquisitions in Turkey, designed for:

• Foreign investors
• Private equity funds
• Strategic buyers
• Corporate groups considering share or asset acquisitions

2. Mergers & Acquisitions in Turkey: Legal Framework Overview

2.1 What Does "Company Acquisition" Mean Under Turkish Law?

Under Turkish law, acquisitions are typically structured as:

• Share purchases (acquisition of shares in an existing company), or
• Asset purchases (acquisition of specific business assets).

The most common M&A structure in Turkey is a share acquisition, governed primarily by:

• Turkish Commercial Code
• Turkish Code of Obligations
• Sector-specific regulations (banking, energy, fintech, etc.)

2.2 Why "Turkey Due Diligence" Is Not a Formality

In many failed or disputed acquisitions, the root cause is not the transaction itself but insufficient pre-acquisition legal review.

Key reasons due diligence is critical in Turkey:

• Contingent tax and social security liabilities
• Unresolved employee claims under Turkish labor law
• Invalid or defective corporate approvals
• Undisclosed shareholder disputes
• Non-compliant contracts under Turkish mandatory law

A well-structured Turkey due diligence process allows buyers to either:

• Walk away from high-risk transactions, or
• Re-price and restructure the deal accordingly.

3. Legal Due Diligence in Turkey: Scope and Methodology

Legal due diligence in Turkish M&A transactions is not limited to document review. It is a risk-mapping exercise aimed at identifying issues that may:

• Invalidate the transaction
• Create post-closing liabilities
• Materially affect valuation

The review typically covers the following core areas.

4. Corporate Due Diligence Checklist

4.1 Corporate Existence and Validity

Key questions:

• Is the target company duly incorporated and legally existing?
• Are the articles of association compliant with current Turkish law?
• Are share records and capital structure accurate?

Red flags include:

• Unregistered capital increases
• Discrepancies between trade registry records and internal documents
• Invalid share transfers

4.2 Shareholding Structure and Transferability

For share acquisitions, it is essential to verify:

• Current shareholders and share ratios
• Existence of share pledges, liens, or usufruct rights
• Pre-emption or approval rights restricting share transfers

Many foreign buyers overlook contractual or statutory restrictions in A.Ş. (joint stock companies) or Ltd. Şti. (limited liability companies) that may block or delay closing.

5. Contractual Due Diligence

5.1 Review of Material Agreements

Legal due diligence must identify and analyze:

• Customer and supplier contracts (supply agreements)
• Distribution and agency agreements
• Lease agreements
• Financing and security documents (bank guarantees)

Key risks:

• Contracts that automatically terminate upon change of control
• Non-assignable agreements
• Clauses violating mandatory Turkish law

Such issues directly affect business continuity after acquisition.

5.2 Related Party Transactions

Transactions with shareholders or affiliated entities are common in Turkish companies.

These arrangements may:

• Distort the company's real financial position
• Create transfer pricing or compliance risks
• Require restructuring before or after closing

6. Employment and Labor Law Due Diligence

Labor liabilities are among the highest risk areas in Turkish acquisitions.

Review should include:

• Employment contracts and internal regulations
• Termination history and pending claims
• Severance and notice pay exposure
• Compliance with working hours and overtime rules

7. Tax and Social Security Exposure (Legal Perspective)

While financial advisors handle tax calculations, legal due diligence must assess:

• Tax audits and disputes
• Social security compliance
• Potential penalties and fines

Tax risks often become bargaining points in:

• Purchase price adjustments
• Escrow mechanisms
• Indemnity clauses

8. Regulatory and Compliance Due Diligence

Depending on the sector, acquisitions may require:

• Regulatory approvals
• Licenses or permits
• Notification to competition authorities (merger control)

Failure to identify missing or defective licenses may result in:

• Administrative sanctions
• Suspension of operations
• Forced divestment

For technology companies, KVKK compliance (data protection) during due diligence is also critical.

9. Litigation and Dispute Risk Analysis

9.1 Pending and Potential Disputes

Legal due diligence must map:

• Ongoing lawsuits (commercial litigation)
• Arbitration proceedings
• Enforcement files

Equally important is identifying latent disputes, such as:

• Shareholder conflicts (minority shareholder disputes)
• Terminated contracts with litigation risk
• Unresolved regulatory investigations

10. From Due Diligence to Contract: Risk Allocation Mechanisms

10.1 Share Purchase Agreement (SPA) in Turkey

Findings from due diligence directly shape the Share Purchase Agreement (SPA).

Typical legal tools include:

• Representations and warranties
• Indemnity clauses
• Price adjustment mechanisms
• Escrow or holdback structures

10.2 Closing Conditions and Post-Closing Protection

Legal due diligence findings often translate into:

• Conditions precedent (CPs)
• Post-closing covenants
• Specific indemnities for identified risks

Ignoring due diligence findings at contract stage effectively nullifies the entire process.

11. Common Mistakes in Turkish M&A Due Diligence

Foreign investors frequently make the following errors:

• Relying solely on financial due diligence
• Underestimating labor law exposure
• Assuming EU-style disclosure standards apply
• Skipping local legal review

12. Conclusion: Due Diligence Is Not a Cost, It Is Risk Insurance

In mergers and acquisitions in Turkey, legal due diligence is not a box-ticking exercise. It is a strategic decision-making tool that protects:

• Capital
• Transaction validity
• Long-term investment value

A properly executed Turkey due diligence process enables investors to:

• Understand what they are truly buying
• Negotiate from a position of strength
• Avoid costly post-acquisition disputes
