How to Conduct Legal Due Diligence Before Signing a Commercial Contract in Turkey | 2026 Updated Legal Guide

Learn how to conduct legal due diligence before signing a commercial contract in Turkey. Discover company verification, litigation checks, financial risks, contract review, regulatory compliance, and practical legal strategies in this 2026 Updated Legal Guide.

Entering into a commercial contract in Turkey without conducting proper legal due diligence can expose businesses to significant financial, operational, and legal risks. Whether you are a foreign investor, multinational corporation, exporter, importer, manufacturer, technology company, franchise operator, or entrepreneur, a carefully drafted contract alone is not enough. Before signing any commercial agreement, it is essential to verify the legal status, financial stability, regulatory compliance, and contractual authority of the other party.

Many commercial disputes in Turkey arise not because the contract was poorly drafted, but because one party failed to investigate the legal and commercial background of its future business partner. A comprehensive legal due diligence process helps identify hidden liabilities, ongoing litigation, tax problems, insolvency risks, regulatory violations, and contractual weaknesses before they become costly disputes.

This 2026 Updated Legal Guide explains how businesses should conduct legal due diligence before signing commercial contracts in Turkey and highlights the most important legal issues foreign companies should examine.

What Is Legal Due Diligence?

Legal due diligence is the process of investigating and verifying the legal status, authority, obligations, liabilities, and compliance of a business or individual before entering into a legally binding agreement.

Its objectives include:

• Identifying legal risks.
• Confirming contractual authority.
• Verifying regulatory compliance.
• Detecting hidden liabilities.
• Preventing commercial disputes.
• Protecting investments.
• Supporting informed business decisions.

Legal due diligence should be completed before any significant commercial commitment is made.

Why Is Due Diligence Important?

Failure to conduct due diligence may result in:

• Contract disputes.
• Financial losses.
• Fraud.
• Breach of contract.
• Tax liabilities.
• Regulatory penalties.
• Supply chain disruptions.
• Litigation.
• Insolvency-related losses.
• Reputational damage.

Preventive legal review is considerably less expensive than resolving commercial disputes after execution of a contract.

Step 1 – Verify Company Registration

Before signing any agreement, verify:

• Company registration.
• Trade registry information.
• Legal name.
• Registration number.
• Registered address.
• Corporate status.
• Date of incorporation.
• Share capital.

Confirm that the company legally exists and remains active.

Step 2 – Confirm Authority to Sign

One of the most common commercial mistakes is signing contracts with individuals who lack authority.

Verify:

• Authorized signatories.
• Board resolutions where required.
• Powers of attorney.
• Signature circulars.
• Corporate authorization documents.

A contract signed by an unauthorized individual may create significant legal complications.

Step 3 – Review Corporate Documents

Important documents include:

• Articles of Association.
• Shareholder structure.
• Board resolutions.
• Commercial registration certificates.
• Signature authorities.
• Corporate licenses.
• Internal governance documents.

These records help confirm the company’s legal capacity.

Step 4 – Check Pending Litigation

Investigate whether the company is involved in:

• Commercial lawsuits.
• Enforcement proceedings.
• Arbitration.
• Bankruptcy proceedings.
• Insolvency applications.
• Administrative disputes.
• Employment litigation.
• Intellectual property disputes.

Ongoing litigation may significantly affect contractual performance.

Step 5 – Review Financial Stability

Legal due diligence should include review of:

• Financial statements.
• Audit reports.
• Debt levels.
• Existing security interests.
• Creditworthiness.
• Liquidity.
• Payment history.
• Financing arrangements.

Financial instability frequently leads to contractual disputes.

Step 6 – Verify Tax Compliance

Businesses should determine whether the counterparty has:

• Outstanding tax liabilities.
• Tax investigations.
• Administrative penalties.
• VAT compliance issues.
• Corporate tax disputes.
• Customs liabilities.

Tax-related risks may affect future business operations.

Step 7 – Examine Regulatory Licenses

Many industries require regulatory approvals.

Examples include:

• Banking.
• Insurance.
• Energy.
• Telecommunications.
• Healthcare.
• Transportation.
• Pharmaceuticals.
• Financial services.

Verify that all required licenses remain valid.

Step 8 – Review Intellectual Property

Where intellectual property is important, confirm:

• Trademark ownership.
• Patent registrations.
• Copyright ownership.
• Domain names.
• Software licenses.
• Confidential know-how.
• Licensing agreements.

IP disputes may significantly reduce commercial value.

Step 9 – Review Existing Contracts

Request copies of important agreements, including:

• Distribution agreements.
• Supply contracts.
• Franchise agreements.
• Lease agreements.
• Financing contracts.
• Shareholder agreements.
• Employment agreements.
• Technology licenses.

Existing contractual obligations may affect future performance.

Step 10 – Verify Compliance Programs

Review whether the company maintains compliance policies relating to:

• Anti-bribery.
• Anti-money laundering.
• Data protection.
• Competition law.
• International sanctions.
• Corporate governance.
• Internal investigations.
• Cybersecurity.

Strong compliance systems reduce legal risks.

Step 11 – Review Data Protection Compliance

Businesses handling personal information should evaluate:

• Data processing procedures.
• Privacy policies.
• Security measures.
• International data transfers.
• Employee confidentiality obligations.
• Cybersecurity policies.

Data protection failures may create substantial liability.

Step 12 – Examine Employment Matters

Review:

• Employment contracts.
• Labor disputes.
• Union issues.
• Occupational safety compliance.
• Employee benefit obligations.
• Executive employment arrangements.

Employment liabilities may significantly affect acquisitions and commercial partnerships.

Step 13 – Evaluate Real Estate Issues

Where property is involved, verify:

• Ownership.
• Lease rights.
• Mortgages.
• Easements.
• Zoning compliance.
• Environmental restrictions.
• Construction permits.

Real estate risks frequently affect commercial projects.

Step 14 – Review Environmental Compliance

Businesses should examine:

• Environmental permits.
• Waste management obligations.
• Pollution liabilities.
• Environmental litigation.
• Regulatory inspections.

Environmental violations may result in significant administrative penalties.

Step 15 – Conduct Sanctions and Compliance Screening

International businesses should verify:

• Sanctions compliance.
• Ultimate beneficial ownership.
• Politically exposed persons (PEPs).
• Restricted party screening.
• International trade restrictions.

Cross-border transactions require enhanced compliance review.

Contract Clauses That Require Special Attention

Every commercial contract should carefully address:

• Scope of work.
• Payment terms.
• Currency provisions.
• Delivery obligations.
• Performance standards.
• Warranties.
• Limitation of liability.
• Indemnification.
• Confidentiality.
• Intellectual property ownership.
• Force majeure.
• Termination rights.
• Governing law.
• Dispute resolution.
• Arbitration clauses.

These provisions often determine the outcome of future commercial disputes.

Common Due Diligence Mistakes

Businesses frequently:

• Rely only on internet searches.
• Skip litigation checks.
• Ignore financial statements.
• Fail to verify signing authority.
• Overlook regulatory licenses.
• Ignore tax risks.
• Use template contracts.
• Skip legal review to save costs.

These mistakes often lead to expensive disputes.

Why Foreign Investors Should Conduct Enhanced Due Diligence

Foreign companies should conduct additional reviews concerning:

• Foreign investment restrictions.
• Currency regulations.
• Tax treaties.
• Customs compliance.
• Competition law.
• Sector-specific licensing.
• Cross-border payment rules.
• International arbitration options.

Cross-border transactions generally involve greater legal complexity.

An experienced commercial lawyer can:

• Conduct comprehensive legal due diligence.
• Verify corporate authority.
• Identify hidden legal risks.
• Review litigation history.
• Analyze contractual liabilities.
