Non-Compete Clauses Between Businesses in Turkey: When Do They Violate Competition Law? (2026 Updated Guide)

When can a non-compete clause between businesses violate Turkish competition law? Learn how duration, territory, market power, vertical agreements, M&A transactions and restrictive contractual provisions are assessed.

Non-compete clauses are frequently used in distribution agreements, dealership contracts, franchise arrangements, joint ventures, share purchase agreements, business transfers and other commercial relationships in Turkey. Their existence does not automatically make an agreement unlawful. However, a non-compete obligation can create significant competition-law risk when it prevents a business from dealing with competing suppliers or customers beyond what is reasonably necessary for a legitimate commercial arrangement. Under Turkish competition law, the analysis generally requires consideration of the purpose and effect of the restriction, the parties’ market positions, the relevant market, duration, territorial scope and whether the restriction is necessary for the underlying transaction.

For foreign companies operating or investing in Turkey, the issue should be addressed before signing the contract. A provision that appears commercially routine can potentially create competition-law exposure, affect contractual enforceability and become relevant during an investigation by the Turkish Competition Authority.

What Is a Business-to-Business Non-Compete Clause?

A non-compete clause restricts one commercial party from competing with another party in a defined manner. For example, a distributor may agree not to sell competing brands, a franchisee may agree not to operate a competing business, or the seller of a company may agree not to establish a competing enterprise after completion of the sale.

The legal assessment depends heavily on the commercial context.

Are Non-Compete Clauses Automatically Illegal in Turkey?

No. Turkish competition law does not treat every non-compete provision as automatically prohibited.

The central question is whether the restriction unlawfully prevents, distorts or restricts competition or whether it can benefit from an applicable exemption or be justified as an ancillary restraint necessary for a legitimate transaction.

Why Does Article 4 of Competition Law Matter?

Article 4 of Law No. 4054 prohibits agreements, concerted practices and decisions between undertakings that have the purpose or effect of preventing, distorting or restricting competition.

A contractual non-compete obligation can therefore fall within competition-law scrutiny where it materially restricts the commercial freedom of an undertaking.

The Relevant Market Must Be Identified

A proper assessment generally begins with the relevant product and geographic markets.

A restriction affecting a highly competitive market with numerous alternatives may create a different competitive impact from an identical restriction imposed in a concentrated market with substantial barriers to entry.

Market Power Matters

The parties’ market positions can materially affect the analysis. Market shares, competing suppliers, customer alternatives, barriers to entry and the overall competitive structure should be examined.

Foreign companies should therefore avoid assessing a non-compete clause solely by reading its wording.

Vertical Agreements Frequently Contain Non-Compete Obligations

Non-compete provisions commonly appear in agreements between businesses operating at different levels of the supply chain, such as manufacturers and distributors.

A supplier may, for example, require a distributor to purchase most or all of its requirements from that supplier or prohibit the distributor from selling competing products.

Such restrictions require careful analysis under the Turkish rules governing vertical agreements.

Exclusivity and Non-Compete Are Closely Related

A contract does not necessarily need to contain the words “non-compete” to create a competition restriction.

Exclusive purchasing obligations, minimum purchase requirements, loyalty rebates or other provisions may have an equivalent practical effect if they substantially restrict the buyer’s ability to purchase competing products.

Duration Is a Critical Factor

The longer the restriction continues, the greater the potential competition concern.

An indefinite obligation preventing a distributor from dealing with competitors can raise substantially different issues from a limited restriction connected with a legitimate investment or commercial relationship.

Five-Year Restrictions Require Particular Attention in Vertical Agreements

Under Turkey’s vertical-agreement framework, the duration of non-compete obligations is an important element of block-exemption analysis. Obligations exceeding the permitted framework or automatically renewable arrangements capable of creating an effectively indefinite restriction require particular scrutiny.

A contract should therefore be reviewed not only for its stated initial duration but also for renewal mechanisms.

Automatic Renewal Can Create Hidden Risk

A contract may technically state that the non-compete obligation lasts three years while automatically renewing repeatedly unless one party terminates it.

The practical duration of the restriction should be examined rather than relying solely on the first contractual period.

Post-Termination Non-Compete Clauses Are More Sensitive

A restriction continuing after the commercial agreement ends may limit the former distributor, dealer or franchisee from participating in the market.

Such clauses require particularly careful assessment of duration, territory, products and necessity.

Know-How Protection Can Be Relevant

A post-contractual restriction may be easier to justify where it is genuinely connected with the protection of substantial know-how transferred during the relationship.

However, simply inserting the word “know-how” into a contract does not automatically justify a broad non-compete obligation.

The information should genuinely possess the characteristics that make protection necessary.

Territorial Scope Should Be Limited

A clause preventing competition throughout Turkey may be difficult to justify where the commercial relationship concerned only a small territory.

The geographic scope should correspond to the legitimate commercial purpose of the restriction.

Product Scope Must Also Be Examined

A non-compete obligation should not automatically prohibit every activity of the restricted company.

If the parties cooperate concerning one category of products, a restriction covering unrelated products or services may be excessively broad.

Customer Restrictions Can Function as Non-Compete Clauses

A provision preventing a business from serving particular customers or customer groups may also restrict competition.

Customer-based restrictions should therefore be assessed together with territorial and product restrictions.

Non-Compete Clauses in Distribution Agreements

Distribution contracts frequently contain provisions preventing distributors from carrying competing brands.

Foreign manufacturers entering Turkey should evaluate whether the restriction is necessary for investment protection, brand development or another legitimate objective and whether it complies with applicable competition-law requirements.

Exclusive Distribution Does Not Mean Unlimited Restriction

Granting a distributor exclusivity in a territory does not automatically permit every restriction on the distributor or other dealers.

Territorial restrictions, customer allocation, online sales limitations and resale restrictions may raise separate competition-law issues.

Online Sales Restrictions Require Separate Review

A contract that effectively prevents a distributor from using online channels may raise competition concerns independent of the general non-compete clause.

Businesses should therefore examine the entire distribution system rather than reviewing one contractual paragraph in isolation.

Franchise Agreements Can Contain Legitimate Restrictions

Franchise systems often depend on common identity, know-how, quality standards and protection of the franchise network.

Certain restrictions may therefore be necessary to preserve the system. However, unnecessarily broad restrictions extending beyond what the franchise relationship requires can still create competition-law risk.

Joint Ventures Require a Different Analysis

Parties establishing a joint venture may need restrictions preventing them from directly competing with the joint venture in its core business.

The question is whether the restriction is genuinely necessary for the establishment and operation of the venture and whether its scope corresponds to that necessity.

Non-Compete Clauses in M&A Transactions

The seller of a business may agree not to compete with the transferred business after closing.

Such restrictions can protect the value of transferred goodwill and know-how and may qualify as ancillary restraints where properly limited.

The Seller Cannot Necessarily Be Restricted Forever

A purchaser may have a legitimate interest in protecting the value of the acquired business, but this does not justify an unlimited prohibition preventing the seller from ever participating in the industry again.

Duration should correspond with the assets, goodwill and know-how transferred.

Geographic Scope in M&A Should Follow the Transferred Business

If the target business operated only in particular markets, a worldwide non-compete obligation may require stronger justification.

The restriction should be examined against the geographic activities actually transferred.

The Restricted Products Should Match the Acquired Business

An acquisition involving one product line does not necessarily justify prohibiting the seller from competing in every other business operated by the buyer.

Overbroad product definitions can create unnecessary risk.

Share Purchase Agreements Should Be Reviewed Before Signing

Competition-law analysis should occur during transaction drafting, not after closing.

If the non-compete clause is too broad, the parties may face uncertainty concerning enforceability and regulatory compliance after the transaction has already been completed.

Minority Shareholders Can Also Create Competition Issues

Non-compete obligations imposed on minority shareholders should be evaluated according to the shareholder’s role, influence, access to confidential information and the commercial necessity for the restriction.

A blanket restriction imposed merely because a person owns shares may be difficult to justify in every situation.

Confidentiality and Non-Compete Should Not Be Confused

A company may have legitimate reasons to protect confidential information without prohibiting competition entirely.

A narrowly drafted confidentiality obligation can sometimes protect the relevant interest with less restrictive effect than a broad non-compete clause.

Non-Solicitation Clauses Also Require Review

Clauses preventing solicitation of customers, suppliers or personnel may affect competitive behavior.

Their legality depends on their scope, duration and relationship with the legitimate interest being protected.

Penalty Clauses Can Increase the Restrictive Effect

A non-compete clause backed by an extremely high contractual penalty may discourage conduct beyond what the written restriction technically prohibits.

The economic effect of enforcement mechanisms should therefore be considered.

Competition Law Looks at Reality, Not Only Contract Language

Businesses should examine how the arrangement actually operates.

An agreement may contain no express exclusivity clause while commercial incentives effectively force the distributor to purchase all products from one supplier.

Conversely, contractual language that appears broad may operate more narrowly in practice, although poor drafting itself can still create legal uncertainty.

Individual Exemption May Become Relevant

Where an agreement restricts competition but produces efficiency benefits, the conditions for individual exemption under Turkish competition law may need to be examined.

The analysis can include improvements in production or distribution, consumer benefits, necessity of the restrictions and preservation of sufficient competition.

The Restriction Must Be Necessary

A central question is whether the commercial objective could reasonably be achieved through a less restrictive provision.

If confidentiality, limited exclusivity or a narrower territorial restriction would protect the legitimate interest, a broad prohibition may be harder to justify.

Competition Authority Investigations Can Examine Contractual Restrictions

The Turkish Competition Authority may examine agreements, commercial practices, communications and market effects during an investigation.

Companies should therefore maintain a documented commercial rationale for significant restrictive provisions.

Internal Emails Can Become Important Evidence

Commercial teams should avoid language suggesting that the objective of a non-compete clause is simply to eliminate competitors, block market entry or divide customers.

Competition-law risk depends on substance, and internal documents can become relevant to understanding the purpose of an arrangement.

Foreign Companies Are Not Outside Turkish Competition Law

A foreign company can face Turkish competition-law scrutiny where its agreements or conduct affect competition in Turkey.

The fact that the agreement was signed abroad or governed contractually by foreign law does not automatically remove Turkish competition-law implications.

Governing-Law Clauses Do Not Eliminate Competition Rules

Parties cannot necessarily avoid mandatory Turkish competition rules simply by choosing another country’s law in their contract.

International agreements affecting the Turkish market should therefore receive a Turkey-specific competition review.

What Happens If a Non-Compete Clause Violates Competition Law?

Potential consequences can include regulatory investigation, administrative fines and problems concerning the validity or enforceability of restrictive contractual provisions.

The exact consequences depend on the nature of the infringement and circumstances of the agreement.

Can the Entire Contract Become Invalid?

This requires a contract-specific analysis. The treatment of an unlawful restriction and its relationship with the remaining provisions can depend on severability, the nature of the agreement and applicable private-law rules.

Businesses should not assume automatically that either the entire agreement survives or the entire agreement fails.

Can the Clause Be Narrowed?

In commercial negotiations, competition concerns can often be reduced by narrowing duration, territory, products, customers or the activities covered.

Drafting should begin with the legitimate interest requiring protection and then impose no broader restriction than necessary.

Existing Contracts Should Be Audited

Companies should periodically review distribution, dealership, franchise, joint-venture and acquisition agreements.

A clause that was appropriate when signed may become problematic if market shares, commercial relationships or regulatory rules change.

Renewals Are an Important Review Point

Before automatically renewing a long-term agreement, reconsider the competition-law treatment of the non-compete obligation.

Do not assume that a clause remains compliant merely because it has existed for years without challenge.

Foreign Investors Should Review Target Company Contracts

During acquisition due diligence, examine whether the Turkish target has imposed excessive exclusivity or non-compete obligations on distributors, dealers, franchisees or suppliers.

Historical competition-law exposure can become an acquisition risk.

Compliance Programs Should Include Distribution Contracts

Businesses frequently focus competition compliance on meetings with competitors while overlooking vertical agreements.

Sales and procurement teams should receive guidance concerning exclusivity, non-compete clauses, territorial restrictions and resale arrangements.

2026 Practical Assessment for Businesses

For contracts operating in Turkey in 2026, non-compete analysis should be performed as part of the overall commercial arrangement rather than through a simple clause-by-clause checklist. Businesses should identify the relevant market, calculate the parties’ market positions where necessary, determine whether the arrangement falls within the applicable vertical or transaction-specific framework, assess duration and renewal, review territorial and product scope, and document why the restriction is commercially necessary.

Frequently Asked Questions

Are non-compete clauses between companies illegal in Turkey?

No. Their legality depends on the structure, market circumstances, duration, scope and applicable competition-law rules.

Can a distributor be prohibited from selling competing products?

Potentially, but the restriction must be assessed under the applicable vertical-agreement and competition-law framework.

Can a non-compete obligation last indefinitely?

Indefinite or effectively indefinite restrictions can create substantial competition-law concerns, particularly in vertical arrangements.

Are post-termination non-compete clauses permitted?

They may be permissible in limited circumstances, but duration, territory, subject matter and necessity require careful review.

Can a seller of a company agree not to compete after the sale?

Yes, a properly limited restriction may protect transferred goodwill and know-how. An unnecessarily broad restriction can create competition-law concerns.

Does choosing foreign law avoid Turkish competition law?

Not necessarily. Turkish competition rules may still apply where the agreement affects competition in Turkey.

Can confidentiality be used instead of a non-compete clause?

In some circumstances, a confidentiality obligation may protect the legitimate commercial interest through a less restrictive mechanism.

Can a non-compete clause lead to a Competition Authority investigation?

Potentially, particularly where the agreement restricts market access, forecloses competitors or forms part of broader anticompetitive conduct.

Should foreign investors review non-compete clauses during due diligence?

Yes. Distribution, franchise, supply, joint-venture and historical acquisition agreements should be examined for potential competition-law exposure.

What should businesses check before signing?

The parties should determine what legitimate interest requires protection and then assess whether the proposed duration, territory, product scope, customer restrictions and enforcement mechanisms go further than necessary. The clause should also be reviewed within the wider competitive structure of the relevant Turkish market.
