Unauthorized Commercial Representative in Turkey: Liability for Contracts Signed Without Authority (2026 Updated Guide)

What happens when a commercial representative signs a contract without authority in Turkey? Learn about unauthorized representation, company approval, third-party claims, apparent authority, damages and legal remedies.

Foreign companies doing business in Turkey frequently authorize managers, employees, distributors, consultants, branch personnel or commercial representatives to negotiate transactions. A serious dispute can arise when a person signs a supply agreement, lease, guarantee, purchase order, settlement, service contract or another commercial document without having authority to bind the company or after exceeding the limits of their authority. The signature does not automatically mean that the foreign company is bound in every case. The legal consequences depend on the source and scope of authority, the type of representation, whether the company later approved the transaction, the conduct of the parties and whether special corporate or statutory rules apply.

What Is Unauthorized Representation?

Unauthorized representation generally arises when a person purports to conclude a legal transaction on behalf of another person or company despite lacking the necessary authority.

The problem can also arise where some authority exists but the representative exceeds its limits. For example, a representative authorized to purchase goods up to a particular amount may sign a substantially larger contract.

First Determine Who Actually Signed the Contract

The first question should be factual: who signed, in what capacity, and on behalf of which entity?

A foreign corporate group may have a parent company, Turkish subsidiary, branch, distributor and local consultant operating simultaneously. A contract signed using a group brand does not necessarily establish which legal entity became a party.

Examine the Signature Block

Review whether the individual signed personally or expressly on behalf of the company. The signature block, company name, title and wording of the contract can provide important evidence concerning the intended representation.

Email correspondence and negotiations should also be examined.

Where Did the Alleged Authority Come From?

Authority may arise from a power of attorney, corporate authorization, commercial representation arrangement or another legally recognized source.

The company should obtain the document relied upon by the purported representative and determine its exact scope.

A Job Title Does Not Automatically Give Unlimited Authority

Titles such as country manager, sales director, business development manager or regional representative should not automatically be treated as authority to conclude every possible transaction.

The legal authority attached to the person’s role and the company’s conduct must be examined separately.

Internal Approval and External Authority Are Different Issues

A representative may violate an internal company policy while still raising separate questions about external representation.

For example, a manager may have been required internally to obtain headquarters approval before a transaction. Whether violation of that requirement prevents the contract from binding the company depends on the legal structure of the representative’s external authority and the facts of the transaction.

Check the Trade Registry and Corporate Records

Where a Turkish company is involved, corporate representation records can be highly important. Determine who was authorized to represent the company at the date the disputed contract was executed and whether representation required a single signature or joint signatures.

Historical records matter because authority may have changed after the contract was signed.

Joint Signature Requirements Can Be Critical

Some companies require two authorized persons to act together. A document bearing only one signature can therefore create a substantial authority dispute.

However, the complete legal and factual circumstances should be reviewed before concluding automatically that the contract is ineffective.

Powers of Attorney Must Be Read Carefully

Do not rely merely on the existence of a power of attorney. Examine what transactions it actually authorizes.

A power covering routine purchasing may not necessarily authorize disposal of substantial assets, settlement of litigation, execution of guarantees or another extraordinary transaction.

Has the Power of Attorney Expired or Been Revoked?

The relevant date is generally the date of the disputed transaction.

Review revocation records, notifications, corporate correspondence and any other evidence concerning termination of authority.

What Happens When a Representative Has No Authority?

Under the general rules of unauthorized representation, a transaction entered into on behalf of another person without authority may depend on whether the represented person subsequently approves it.

Accordingly, one of the most important questions is whether the company later ratified the transaction expressly or through legally relevant conduct.

Can the Company Approve the Contract Later?

Potentially. A company that initially did not authorize the representative may subsequently approve the transaction.

Once a dispute arises, companies should therefore be careful about communications and conduct that could be interpreted as acceptance of the agreement.

Conduct After Signing Can Become Important Evidence

Consider whether the company delivered goods, accepted payment, issued invoices, performed services, demanded performance, relied on the contract or otherwise behaved consistently with its existence.

Such facts may become relevant to arguments concerning subsequent approval or other legal consequences.

Silence Should Not Automatically Be Treated as Approval

Whether silence has legal consequences depends on the circumstances and applicable rules.

A company receiving notice of an unauthorized transaction should nevertheless respond promptly rather than leaving the position uncertain.

The Counterparty May Request Confirmation

Where the counterparty learns that authority is disputed, it may seek confirmation from the company.

The company should investigate the transaction before providing any statement that could later be interpreted as ratification.

What If the Company Refuses to Approve the Contract?

If the transaction is not binding on the purported principal because authority was absent and approval is not given, liability of the unauthorized representative may become relevant.

The precise consequences depend on the circumstances, including what the representative represented about their authority and what the counterparty knew.

Can the Unauthorized Representative Be Personally Liable?

Potentially. A person purporting to act with authority that they do not possess can face liability toward the counterparty under the applicable rules.

However, personal liability should not be assumed without examining the transaction, knowledge of the parties and statutory framework.

Did the Counterparty Know Authority Was Missing?

This can be an important issue. A sophisticated counterparty that knew the representative lacked authority may be in a different position from a party reasonably relying on documentation provided by the representative.

Preserve negotiations showing what each party knew before signing.

Due Diligence by the Counterparty Matters

For high-value transactions, counterparties commonly request signature circulars, powers of attorney, board resolutions or other evidence of authority.

Failure to investigate an obvious authority problem can become relevant to the dispute.

Apparent Authority Arguments May Arise

A counterparty may argue that the company’s own conduct created a reasonable appearance that the representative was authorized.

These disputes are highly fact-specific. Relevant evidence may include company email accounts, business cards, prior contracts, introductions by senior management, previous transactions and the company’s treatment of the representative.

Prior Transactions Can Be Important

If the same person signed numerous earlier contracts that the company performed without objection, the counterparty may rely on that history.

The company should therefore review the entire commercial relationship rather than examining the disputed agreement in isolation.

Company Email Accounts Can Become Evidence

Negotiations conducted through an official corporate email address may be used to support arguments concerning the person’s role.

However, possession of a company email account alone should not automatically establish unlimited contractual authority.

Company Letterhead and Stamps Can Create Additional Issues

A representative may have access to letterhead, corporate stamps or digital documents. Their use can strengthen the appearance of authorization but does not necessarily resolve the underlying legal authority.

If company materials were misused, preserve evidence of how they were accessed.

What If the Representative Used a Fake Signature?

Forgery presents a substantially different issue from merely exceeding genuine authority.

The company should preserve the original document, obtain signature evidence where necessary and evaluate civil and criminal remedies.

Electronic Signatures and Digital Contracts

Authority disputes increasingly arise from electronically executed agreements, procurement platforms and digital approvals.

Preserve electronic logs, authentication information, timestamps, account access records and the complete digital version of the agreement.

Unauthorized Guarantees Require Particular Attention

A manager may sign a guarantee, surety-type undertaking or other security instrument outside ordinary commercial operations.

Such obligations should be examined carefully for both representative authority and any special validity requirements applicable to the particular security.

Unauthorized Asset Sales

Where a representative attempts to sell machinery, vehicles, shares, real estate or other valuable assets, the company should act quickly.

Depending on the asset and transaction, registration systems, third-party rights and special formal requirements may significantly affect available remedies.

Unauthorized Settlement Agreements

A representative may purport to waive claims or settle a major dispute without authority.

The scope of the representative’s power should be examined carefully because authority to manage ordinary commercial matters does not necessarily resolve authority to compromise significant legal claims.

Unauthorized Purchase Orders

Purchase-order disputes are particularly common in international trade.

A local employee may order substantial quantities while the foreign company argues that headquarters approval was required. The analysis should include prior ordering practices, supplier knowledge and the company’s previous acceptance of similar transactions.

Distribution Relationships Can Create Authority Confusion

An independent distributor normally operates as a separate business, but customers may mistakenly believe it represents the foreign manufacturer directly.

Foreign manufacturers should clearly distinguish distributors from agents or representatives in contracts and commercial communications.

Commercial Agents and Representatives Should Have Defined Powers

The agreement should identify whether the person may negotiate, collect orders, execute contracts, receive payments, make warranties, settle disputes or appoint sub-agents.

Ambiguous authority provisions increase litigation risk.

Foreign Companies Should Control Local Authority Documents

Companies operating internationally should maintain a central record of powers of attorney and other representation documents issued for Turkey.

Expired or unnecessary authority should be addressed promptly through legally appropriate procedures.

What If the Representative Was Dismissed but Continued Signing Contracts?

This can create a particularly difficult dispute if third parties were unaware of the termination.

The company should document termination of authority and evaluate whether relevant counterparties or registries needed to be notified.

Internal Emails Can Become Important Evidence

Emails showing that the representative knew approval was required may support the company’s internal position.

However, the external counterparty’s knowledge remains a separate issue.

WhatsApp and Other Messages Can Also Matter

Commercial authority is frequently discussed through messaging applications. Preserve the full conversation rather than isolated screenshots.

The identity of participants, context and integrity of digital evidence may become disputed.

Can the Foreign Parent Company Be Bound?

Not automatically. A Turkish subsidiary and its foreign shareholder or parent are separate legal entities.

If a Turkish employee signs “for the group,” the precise entity represented must be identified. Corporate-group branding alone should not automatically transfer contractual liability to the foreign parent.

Can a Turkish Subsidiary Be Bound by the Foreign Parent’s Employee?

Again, authority must be established. Employment by one group company does not automatically authorize the employee to contract on behalf of another legal entity.

Intercompany authority documents and actual business practices should be reviewed.

Emergency Injunctions May Be Necessary

If the counterparty attempts to enforce an unauthorized transaction immediately, interim judicial protection may need to be considered depending on the circumstances.

This can be especially important where assets, bank guarantees, shares or other high-value rights are at risk.

Bank Guarantees Require Immediate Review

If an unauthorized contract is connected with a demand guarantee, the underlying authority dispute and the independent nature of the guarantee may create separate legal problems.

Waiting until payment has already occurred can substantially reduce practical options.

Preserve Evidence Immediately

The company should collect the disputed contract, drafts, emails, messages, powers of attorney, signature records, corporate resolutions, registry records, previous contracts, invoices and payment information.

Do not allow employees to delete communications after the dispute arises.

Conduct an Internal Authority Audit

Determine what authority the representative actually had, what internal limitations existed, what third parties were told and whether previous unauthorized conduct was tolerated.

The company’s own historical practices may become decisive.

Send a Carefully Drafted Notice

If the company rejects the transaction, communications with the counterparty should clearly preserve the company’s legal position.

An improvised email from an employee can unintentionally complicate the dispute.

Avoid Partial Performance Before Legal Review

If authority is genuinely disputed, performing part of the contract may create arguments concerning approval.

The company should determine its legal strategy before making payments, accepting deliveries or demanding contractual performance.

Review Potential Claims Against the Representative

Where the representative deliberately exceeded authority or caused losses, the company may need to consider contractual, employment, compensation or other claims.

If fraud, forgery or misappropriation is involved, criminal-law issues may also arise.

Review Potential Claims Against Third Parties

If another person knowingly participated in unauthorized conduct, additional liability questions may arise.

The factual relationship between the representative and counterparty should therefore be investigated.

International Contracts Require Governing-Law Analysis

A contract connected with Turkey does not automatically mean every issue is governed exclusively by Turkish substantive law.

Foreign companies should review governing-law, jurisdiction and arbitration clauses as well as mandatory Turkish rules that may apply.

Arbitration Clauses Can Create a Preliminary Dispute

If the unauthorized representative signed a contract containing an arbitration clause, a dispute may arise over whether the company ever consented to arbitration.

Authority to enter the underlying agreement and authority relating to the arbitration agreement may therefore require careful analysis.

2026 Risk Management for Foreign Companies

Foreign companies operating in Turkey should maintain clear signing matrices, transaction limits, dual-approval requirements, current powers of attorney and centralized records of authorized representatives. Major counterparties should receive accurate authority documentation, and revoked authority should be addressed promptly.

The objective is to prevent a commercial dispute from becoming a factual battle over whether an employee, consultant or distributor appeared authorized.

Immediate Action Plan

When a contract is discovered to have been signed without authority, the company should immediately identify the signatory, determine the represented entity, obtain the original authority documents, check corporate representation records, review internal limitations, investigate the counterparty’s knowledge, examine prior transactions, preserve electronic evidence, determine whether any subsequent conduct could constitute approval, stop unnecessary performance and evaluate urgent judicial measures where assets or enforcement are at risk.

Frequently Asked Questions

Is a contract automatically binding because an employee signed it?

No. The employee’s authority and the surrounding circumstances must be examined.

What if the employee had authority but exceeded a financial limit?

The effect depends on the nature of the limitation, the applicable representation rules and what the counterparty knew or should legally be treated as knowing.

Can the company approve an unauthorized contract later?

Potentially. Subsequent approval can materially change the legal position.

Can the company accidentally approve the agreement through its conduct?

Conduct after signing can become relevant. Accepting performance, making payments or demanding contractual rights should therefore be assessed carefully.

Can the unauthorized representative become personally liable?

Potentially, depending on the applicable rules and circumstances surrounding the representation.

Does a company title prove authority?

Not necessarily. Titles and actual legal authority should be distinguished.

What if the representative forged an authorized director’s signature?

Forgery raises separate and potentially serious civil and criminal issues. Original documents and signature evidence should be preserved immediately.

Can the foreign parent company be liable for a contract signed by a Turkish subsidiary employee?

Not automatically. The employee must have authority capable of binding the relevant foreign entity or another legal basis for liability must exist.

Can the company seek urgent court protection?

Potentially, particularly where immediate enforcement, transfer of assets or another difficult-to-reverse consequence is threatened.

What should a foreign company do first?

Do not focus only on whether headquarters internally approved the transaction. Determine what authority legally existed, what the counterparty knew, how the company presented the representative to third parties and whether subsequent conduct could be interpreted as approval of the contract.
