Arbitration in Turkey: A Practical Guide for Businesses Considering Istanbul

When a business signs a major commercial agreement, the arbitration clause is often one of the provisions that receives the least attention.

That can be a mistake.

Most companies are focused on getting the deal completed. They negotiate the price, delivery schedule, warranties, payment terms and termination rights. The question of what happens when the relationship goes wrong may be left until the end of the contract.

By then, it may be too late to make meaningful changes.

For companies doing business with Turkish businesses, foreign investors entering Türkiye, contractors working on Turkish projects, exporters, importers and international groups with Turkish subsidiaries, arbitration in Turkey can be an important part of commercial risk management.

Türkiye has a well-established framework for international arbitration. Its International Arbitration Law No. 4686 was adopted in 2001, and UNCITRAL's official Model Law information identifies Türkiye among the jurisdictions whose international arbitration legislation is based on or influenced by the Model Law.

But choosing arbitration is not simply a matter of inserting the words "any dispute shall be referred to arbitration" into a contract.

The seat, applicable law, arbitration rules, institution, language, number of arbitrators and eventual enforcement of the award can all matter.

For that reason, arbitration should be considered when the contract is being negotiated—not only after a dispute has already started.

What Is Arbitration?

In simple terms, arbitration allows parties to have a dispute decided by an independent arbitrator or arbitral tribunal instead of having the dispute determined through ordinary court litigation.

The parties agree in advance, or after a dispute has arisen, that the matter will be submitted to arbitration.

The exact procedure depends on the agreement and the applicable arbitration rules.

For international commercial disputes, the UNCITRAL arbitration framework provides important international reference points covering arbitration agreements, tribunal constitution, proceedings, interim measures and awards.

Arbitration can be particularly attractive when the parties are based in different countries and do not want their dispute to be determined exclusively through the courts of one party's home country.

It can also give commercial parties more influence over matters such as the selection of arbitrators and procedural arrangements.

How Does Arbitration Work in Turkey?

The first thing to understand is that Turkish arbitration law distinguishes between different types of arbitration.

International arbitration in Türkiye is principally addressed by Law No. 4686, while domestic arbitration is generally governed by the relevant provisions of the Turkish Code of Civil Procedure No. 6100.

The official Turkish legislation database should be consulted for the current text of the applicable legislation.

Whether a particular arbitration qualifies as international can depend on factors such as the parties, the transaction and the relationship between the dispute and different countries.

That distinction can affect the applicable legal framework.

So, before starting an arbitration, it is sensible to establish exactly which Turkish arbitration regime applies.

Turkish International Arbitration Law No. 4686

Law No. 4686 is particularly important for international arbitrations falling within its scope.

The legislation addresses matters such as:

• arbitration agreements;

• jurisdiction of arbitral tribunals;

• appointment of arbitrators;

• challenges to arbitrators;

• conduct of proceedings;

• interim measures;

• arbitral awards; and

• annulment proceedings.

The Turkish framework is closely connected with international arbitration principles.

The UNCITRAL Model Law on International Commercial Arbitration was developed to help countries modernize and harmonize their arbitration legislation. It covers the main stages of an international arbitration, from the arbitration agreement through the arbitral proceedings and recognition of awards.

This international orientation is one reason Turkish arbitration law is particularly relevant to companies involved in cross-border transactions.

Domestic Arbitration and International Arbitration Are Not the Same

It is tempting to assume that every arbitration involving a Turkish company is an international arbitration.

That is not necessarily the case.

The legal classification of the arbitration matters, and the applicable provisions may differ.

For example, a dispute between parties operating entirely within Türkiye may fall under the domestic arbitration provisions of the Turkish procedural system, whereas a transaction involving international elements may fall within the international arbitration framework.

This is one of those areas where a short legal review at the beginning can prevent much more complicated arguments later.

Why Do Companies Choose Arbitration?

There is no single reason businesses choose arbitration.

For some companies, the biggest attraction is having a neutral forum.

For others, it is the ability to choose an arbitrator with experience in a particular industry.

For an international business, however, enforcement may be one of the most important considerations.

An arbitration award may need to be enforced in a country different from the country where the arbitration was conducted.

That is where the international arbitration framework becomes especially important.

The New York Convention, officially administered through the UNCITRAL framework, establishes international standards for the recognition and enforcement of foreign and non-domestic arbitral awards.

Türkiye is a party to the Convention. UNCITRAL's status information for Türkiye records Türkiye's accession in 1992.

For businesses, this means enforcement should be considered when the arbitration clause is drafted—not after an award has already been obtained.

Why Is Istanbul Important for Arbitration?

Istanbul is one of Türkiye's principal commercial centers and has considerable experience with international business transactions.

It is also home to the Istanbul Arbitration Centre (ISTAC).

The official ISTAC arbitration information explains the institution's role in administering domestic and international arbitration proceedings.

For parties dealing with Turkish businesses, an Istanbul-based arbitration framework may sometimes offer a practical connection between the commercial relationship and the dispute-resolution process.

But selecting Istanbul should still be a deliberate decision.

The parties should understand what it means to select Istanbul as the seat of arbitration, rather than simply choosing Istanbul as the physical location for a hearing.

What Does the "Seat of Arbitration" Mean?

The seat of arbitration is a legal concept.

It is not necessarily the same thing as the place where every hearing will take place.

For example, parties could agree on Istanbul as the legal seat while witnesses or experts participate remotely or while particular procedural events take place elsewhere, depending on the applicable rules and tribunal's directions.

The seat can have consequences for:

• the procedural law governing the arbitration;

• the role of national courts;

• applications relating to the tribunal;

• interim judicial assistance; and

• challenges or annulment of the award.

For that reason, "Istanbul" should not simply be inserted into a contract because it sounds convenient.

The parties should understand the legal consequences of that choice.

Istanbul Arbitration Centre (ISTAC)

ISTAC is an important option for parties considering arbitration connected with Türkiye.

The ISTAC website provides information about its arbitration and mediation services, while its Arbitration Rules set out the procedural framework for cases administered by the institution.

ISTAC also provides model arbitration clauses that businesses can consider when drafting contracts.

Using an institutional arbitration center can be useful because the parties are not starting from scratch when a dispute occurs. The institution's rules provide an established procedural structure.

That does not mean ISTAC is automatically the right choice for every contract.

A multinational company may prefer ICC arbitration. Another business may prefer an ad hoc UNCITRAL arbitration. A domestic Turkish transaction may have entirely different considerations.

The appropriate choice depends on the transaction.

ICC Arbitration and Turkey

Turkish parties can also agree to arbitration administered by the International Chamber of Commerce (ICC).

The official ICC Arbitration Rules provide the procedural framework for ICC arbitrations.

For international companies already using ICC arbitration elsewhere in their global contracts, selecting ICC arbitration for a Turkish transaction may provide procedural familiarity.

The parties can also consider Istanbul as the seat while using ICC Rules, provided the arbitration agreement is properly structured.

The key is to keep the different elements separate:

Institution: Who administers the arbitration?

Rules: What procedural rules apply?

Seat: Where is the arbitration legally based?

Governing law: Which substantive law governs the underlying contract?

Language: In what language will the proceedings be conducted?

These are different questions, even though they frequently appear together in arbitration clauses.

UNCITRAL Arbitration Rules

An institutional arbitration is not the only option.

Parties can also agree to arbitration under the UNCITRAL Arbitration Rules.

The official UNCITRAL Arbitration Rules provide procedural rules for arbitration and include provisions dealing with matters such as arbitrator appointments, submissions, hearings and awards.

UNCITRAL also publishes information about its Expedited Arbitration Rules, which can be relevant to parties looking for a more streamlined procedure where the applicable conditions are satisfied.

Whether an ad hoc or institutional model makes sense depends on the circumstances.

For a sophisticated international transaction, that decision should be made during contract drafting rather than left to the parties when relations have already deteriorated.

Drafting an Effective Arbitration Clause

A good arbitration clause does not need to be unnecessarily complicated.

It does, however, need to be carefully considered.

Depending on the transaction, the parties may need to address:

• the arbitration institution;

• the arbitration rules;

• the seat;

• the governing law;

• the language;

• the number of arbitrators;

• appointment procedures;

• the scope of disputes covered;

• mediation or negotiation requirements;

• interim relief; and

• confidentiality.

The ISTAC model clauses and ICC model arbitration clauses can be useful starting points, but a model clause should not simply be copied into every contract.

The clause should fit the actual transaction.

Why Ambiguous Arbitration Clauses Can Cause Problems

Imagine that a contract says:

"Any dispute shall be resolved by arbitration in Istanbul."

At first glance, that may appear sufficient.

But several questions immediately arise.

Which arbitration rules apply?

Is the arbitration institutional or ad hoc?

How many arbitrators will there be?

Who appoints them?

What is the governing law?

What is the language?

Is Istanbul the legal seat or merely the hearing location?

What disputes are actually covered?

What happens if the contract contains related agreements with different dispute-resolution provisions?

These questions may become important precisely when the parties are already fighting.

A carefully drafted clause can reduce that uncertainty.

Can Foreign Companies Use Arbitration in Istanbul?

Yes, subject to the applicable legal framework and arbitration agreement.

A foreign company may have a Turkish subsidiary, supplier, contractor, distributor, joint-venture partner or other business relationship in Türkiye.

Its contract may provide for arbitration in Istanbul.

The parties may also choose a different institution, governing law or language depending on their commercial objectives.

For foreign businesses, it is particularly useful to examine the arbitration clause together with the rest of the contract rather than treating it as an isolated paragraph.

The Republic of Türkiye's official investment information and Ministry of Trade resources can also provide useful official background for companies considering business activities in Türkiye.

Enforcement of Foreign Arbitral Awards in Turkey

Winning an arbitration does not necessarily mean the successful party immediately receives payment.

The respondent may refuse to comply voluntarily.

The successful party may then need to seek recognition and enforcement where the respondent has assets.

For a foreign award being enforced in Türkiye, Turkish procedural requirements and applicable international conventions must be considered.

The New York Convention's official UNCITRAL materials provide the international framework, while Türkiye's Convention status confirms its participation.

The practical lesson is simple:

Do not wait until the award is issued to think about enforcement.

Before commencing an arbitration, it is worth identifying where the respondent's assets are likely to be found.

Enforcing a Turkish Award Abroad

The reverse situation is also possible.

A party may obtain an arbitration award in Türkiye but need to enforce it against assets located in another country.

The enforcement jurisdiction will have its own procedural requirements.

The New York Convention contracting-state information can be used to determine the Convention status of relevant countries, although the actual enforcement process still requires jurisdiction-specific legal analysis.

For a business with a large international counterparty, this can be a major part of the arbitration strategy.

Can an Arbitration Award Be Challenged in Turkey?

Arbitration is intended to provide a final determination, so it does not generally operate like an ordinary court case with unrestricted appeals.

Depending on the applicable arbitration regime, a party may have the right to seek annulment of an award on specified grounds.

That is different from simply asking another decision-maker to reconsider the merits because the party disagrees with the arbitrators.

The applicable legislation, procedural history and circumstances of the case need to be examined before deciding whether an annulment application is available or advisable.

Arbitration and Interim Measures

Commercial disputes do not always wait patiently for a final award.

A party may be worried that assets could be transferred, evidence could disappear or contractual rights could be undermined while the arbitration is pending.

Interim measures can therefore become an important part of an arbitration strategy.

The UNCITRAL Model Law provisions concerning interim measures recognize the importance of interim protection in international arbitration.

The relationship between arbitral tribunals and national courts can be particularly important when urgent assistance is required.

A lawyer should therefore consider possible interim relief at the beginning of the case, not only after the main arbitration has progressed.

Evidence in Turkish Arbitration

Arbitration may be more flexible than traditional litigation in certain respects, but that does not mean that evidence becomes unimportant.

Quite the opposite.

A successful arbitration often depends on how effectively the evidence is organized and presented.

Depending on the dispute, this might include:

• contracts and amendments;

• invoices;

• bank records;

• correspondence;

• emails;

• technical reports;

• accounting records;

• photographs;

• project documentation;

• expert reports;

• witness statements; and

• electronic records.

The evidence required in a construction dispute will naturally differ from that required in a shareholder dispute or international sale-of-goods claim.

The legal team should therefore develop an evidence strategy around the actual issues in dispute.

Construction Arbitration in Turkey

Construction projects can produce complicated disputes because several contracts and parties may be involved in the same project.

A single project might include:

• the employer;

• main contractor;

• subcontractors;

• architects;

• engineers;

• consultants;

• lenders;

• insurers;

• suppliers; and

• foreign investors.

Disputes can involve delay, defects, payment certificates, variations, extensions of time, termination, guarantees and additional costs.

Technical evidence may also play a central role.

For these reasons, arbitration clauses in construction agreements should be reviewed carefully and consistently across the project's contractual structure.

The Turkish Ministry of Environment, Urbanization and Climate Change and Presidential Investment Office provide official resources relevant to different aspects of investment, construction and business activity in Türkiye.

Energy and Infrastructure Arbitration

Energy and infrastructure projects can involve significant investments and long contractual periods.

Disputes may arise years after the original agreement was signed.

The parties may therefore need to consider arbitration alongside:

• project financing;

• guarantees;

• shareholder arrangements;

• construction contracts;

• supply agreements;

• concession arrangements; and

• insurance policies.

Consistency between the dispute-resolution clauses in these documents can be extremely important.

If five related agreements contain five different arbitration mechanisms, resolving the dispute can become unnecessarily complicated.

Shareholder and Joint Venture Disputes

Arbitration can also be relevant to private corporate relationships.

For example, shareholders or joint-venture partners may disagree about:

• capital contributions;

• management;

• profit distributions;

• valuation;

• transfer of shares;

• deadlock;

• contractual obligations;

• exit rights; or

• termination.

One issue deserves particular attention: who is actually bound by the arbitration agreement?

A company may be party to one agreement while its shareholders, directors, affiliates or other participants are parties to different documents.

Determining whether a particular person or entity can be required to arbitrate may become an important jurisdictional question.

Investment Arbitration

Investment arbitration is a separate and more specialized area.

A commercial arbitration normally arises from a contract between private parties.

An investment arbitration may instead arise from an investment treaty or another legal instrument providing consent to investor-State arbitration.

Türkiye is a member of the ICSID Convention, which entered into force for Türkiye on 2 April 1989 according to the official ICSID member-state information.

Investment disputes can raise complex questions concerning:

• jurisdiction;

• nationality;

• protected investments;

• treaty obligations;

• expropriation;

• fair and equitable treatment;

• discrimination;

• damages; and

• enforcement.

They require a different analysis from an ordinary contractual arbitration between two companies.

Arbitration and Mediation in Turkey

Arbitration is not the only alternative to litigation.

Mediation can sometimes resolve a commercial disagreement before it reaches the arbitration stage.

The basic difference is important:

Mediation helps the parties negotiate a settlement.

Arbitration results in a decision by an independent arbitral tribunal.

The two processes can also be combined in an appropriately drafted dispute-resolution mechanism.

ISTAC provides information about both arbitration and mediation services, and Turkish law contains a broader framework for mediation in civil disputes.

Businesses should nevertheless take care when drafting multi-stage clauses. A poorly worded requirement to negotiate or mediate before arbitration can itself become the subject of procedural arguments.

Is Arbitration Confidential in Turkey?

Confidentiality is often one of the reasons businesses prefer arbitration.

However, it is better not to assume that every aspect of every arbitration is automatically confidential in exactly the same way.

Confidentiality can depend on:

• applicable legislation;

• institutional rules;

• procedural orders;

• contractual provisions; and

• the circumstances in which information is later used.

A company handling trade secrets, proprietary technology, financial information or sensitive business data should address confidentiality deliberately.

Can Arbitration Hearings Be Held Online?

Modern arbitration increasingly uses remote hearings.

This can be particularly practical when the parties, lawyers, witnesses and experts are located in different countries.

ISTAC has published dedicated Online Hearing Rules and Procedures dealing with hearings conducted by teleconference or videoconference.

Remote proceedings can reduce travel and scheduling difficulties, but they also require careful attention to:

• document management;

• witness examination;

• confidentiality;

• cybersecurity;

• technology;

• interpretation; and

• presentation of evidence.

Arbitration vs. Court Litigation in Turkey

There is no rule saying that arbitration is always better than litigation.

The better choice depends on the dispute.

Arbitration may be attractive where parties want a neutral forum, specialist arbitrators or an internationally enforceable award.

Court proceedings may be preferable where extensive judicial powers or participation of third parties is important, or where the dispute cannot validly be submitted to arbitration.

The right question is therefore not:

"Is arbitration better?"

It is:

"Which dispute-resolution mechanism best protects the commercial interests of these particular parties?"

When Should You Speak to an Arbitration Lawyer?

The best time to obtain arbitration advice is often before there is a dispute.

A Turkish arbitration lawyer can review a proposed contract and consider issues such as:

• whether the arbitration clause is effective;

• whether the chosen seat is appropriate;

• whether ISTAC, ICC, UNCITRAL or another mechanism makes sense;

• what governing law should apply;

• whether the clause covers all relevant disputes;

• whether related contracts create inconsistencies;

• where enforcement is likely to be required; and

• whether mediation should form part of the dispute-resolution process.

Early advice can be considerably simpler than trying to resolve an ambiguous arbitration clause after the commercial relationship has collapsed.

What If an Arbitration Dispute Has Already Started?

The first step should normally be to review the relevant contract and arbitration agreement carefully.

The parties should identify:

1. Which arbitration rules apply?

2. What is the seat?

3. Which institution, if any, administers the arbitration?

4. What is the deadline for responding?

5. Is there a jurisdictional objection?

6. Who has been appointed as arbitrator?

7. What evidence is available?

8. What relief is being requested?

9. Are interim measures necessary?

10. Where are the opposing party's assets?

11. Could the dispute be settled?

12. What will happen after the award?

These questions help transform a general dispute into a manageable legal strategy.

A Practical Checklist Before Signing a Turkish Arbitration Clause

Before signing an important contract involving Türkiye, consider the following:

Contract

• Is the arbitration clause clearly written?

• Does it cover the disputes you actually expect could arise?

• Does it work consistently with the rest of the agreement?

Procedure

• Which arbitration rules apply?

• Is the arbitration institutional or ad hoc?

• How many arbitrators will hear the case?

• How are arbitrators appointed?

Seat

• Is Istanbul the appropriate legal seat?

• What consequences will that choice have?

Governing Law

• Which law governs the contract?

• Which law governs the arbitration agreement?

Language

• Will the arbitration be conducted in Turkish, English or another language?

Enforcement

• Where are the counterparty's assets?

• Where might enforcement eventually be required?

Strategy

• Is mediation appropriate?

• Could interim protection be required?

• Are there related contracts with different dispute-resolution clauses?

A few hours spent answering these questions during contract negotiations can save considerable time and expense later.

Arbitration Lawyers in Istanbul for Turkish and International Disputes

Arbitration can provide an effective way of managing commercial disputes, particularly where the parties operate across borders.

But arbitration works best when it is planned carefully.

The arbitration clause should fit the transaction. The seat should have a reason behind it. The institution and rules should be selected deliberately. And enforcement should be considered before proceedings begin.

Kurucuk & Associates Law Firm advises Turkish and international clients on Turkish arbitration law, international commercial arbitration, arbitration agreements, ISTAC proceedings, arbitration-related court proceedings, interim measures, annulment, recognition and enforcement of arbitral awards.

Businesses can also consult authoritative official resources including the Turkish legislation database, UNCITRAL arbitration resources, the UNCITRAL Model Law, the New York Convention, ISTAC, the ICC Arbitration Rules, ICSID and the Republic of Türkiye Investment Office.
