What can a foreign investor or company do when a Turkish business partner secretly transfers contracts, customers and revenue to a new company? Learn about injunctions, evidence and compensation claims.
A Turkish business partner who secretly transfers contracts, customers and revenue to a newly established company may expose both the partner and the new company to serious legal claims. The conduct may involve breach of contract, unfair competition, misuse of confidential information, diversion of corporate opportunities or breach of management duties.
However, not every customer who changes suppliers or every new company established by a former partner is automatically unlawful. The injured company must prove how the customer relationships, contracts or revenue were diverted and whether the conduct violated contractual, corporate or commercial obligations.
Foreign investors should act quickly because digital records may be deleted, customers may be pressured to sign new contracts and revenue may continue flowing to the new company.
Customer and revenue diversion may occur when a partner, director, manager or employee uses the original company’s relationships and resources to benefit another business.
Examples include:
The legal assessment depends on ownership, authority, contractual restrictions, customer consent, the partner’s duties and the financial impact on the original company.
A partner may establish another business in some circumstances, but the partner may be restricted by contractual, corporate, confidentiality, non-compete or good-faith obligations.
The issue becomes more serious where the partner:
A customer’s voluntary decision to change suppliers is not necessarily unlawful. The company should focus on the partner’s conduct and the use of company resources.
If the contracts and customers belonged to the Turkish company, the company may be the primary claimant. A foreign shareholder may need to request corporate action, challenge management conduct or use a derivative remedy where legally available.
A foreign investor may have a direct claim if:
The new company may also be sued where it knowingly participated in the diversion or benefited from confidential information, unauthorized transfers or an unlawful transaction.
Standing should be determined before filing because a shareholder cannot automatically recover every loss suffered by the company.
The injured company or foreign investor should preserve:
Digital evidence should be retained in its original form with metadata where possible. Screenshots alone may not establish authenticity or show the complete conversation.
In urgent circumstances, the injured company may request an interim injunction to prevent specific acts, such as:
The applicant generally must show a credible claim, urgency and a serious risk of harm. The court may require security and will examine whether the requested measure is specific and proportionate.
A broad request preventing all competition may be difficult to obtain. The application should identify the exact customers, contracts, data or assets at risk.
If the company has a monetary claim for lost revenue, diverted payments or compensation, a precautionary attachment may be considered.
The applicant should identify the legal claim, estimate the financial loss and show that the defendant may transfer or conceal assets. The court may require security.
Potential assets may include:
A shareholder cannot automatically attach the new company’s assets for a loss suffered by the original company. The claim and legal connection must be established.
The answer depends on how the contracts were transferred. If a director or partner signed a transfer without authority, the original company may challenge the transaction or seek compensation.
If the customer willingly terminated the original contract and signed a new agreement, the company may not automatically recover the contract. However, the partner’s use of confidential information, pressure, deception, unauthorized representation or breach of a non-compete obligation may create separate claims.
The company should review the contract’s assignment, termination, confidentiality, non-solicitation and change-of-control provisions.
Potential compensation may include:
The claimant must establish causation and avoid double recovery. Revenue is not the same as profit, and the court may require financial analysis showing what the company would likely have earned.
A forensic accountant may compare historical sales, customer contracts, margins, expenses and the revenue received by the new company.
A non-compete or non-solicitation clause may help protect customer relationships, but its enforceability depends on its wording, duration, territory, scope and the parties’ legal relationship.
A clause that is too broad may face challenges. A properly drafted restriction identifying the protected business interest and reasonable limits may provide stronger protection.
Even without a specific clause, misuse of confidential information, unauthorized diversion of contracts or breach of management duties may create legal liability.
In appropriate circumstances, the original company may bring claims against both the partner and the new company. This may be relevant where the new company knowingly received customers, contracts, funds, equipment, data or business opportunities belonging to the original company.
The claimant should explain the role of each defendant separately. A general allegation that both companies are connected may not be sufficient.
Evidence of common ownership, shared employees, identical advertising, transferred invoices, shared bank instructions and customer communications may help establish coordinated conduct.
Criminal issues may arise if the evidence indicates forgery, fraud, unauthorized access to systems, misappropriation, deliberate destruction of records or unlawful use of company property.
A commercial disagreement or lawful competition is not automatically a crime. A criminal complaint should be based on specific conduct and documents rather than suspicion alone.
Civil, corporate, tax and criminal proceedings should be coordinated carefully because statements made in one proceeding may affect the others.
In 2026, customer diversion disputes increasingly involve cloud CRM systems, digital invoices, online payment platforms, electronic signatures, business messaging and social media advertising.
A practical strategy should include:
Lawyer Fırat Fesih Kaya assists foreign companies and investors with customer diversion, unfair competition, shareholder disputes, injunctions and compensation claims in Turkey.
1. Can a Turkish business partner transfer company customers to a new company?
Not necessarily. The transfer may create liability if the partner uses company assets, confidential information, contracts or authority for personal benefit.
2. Can the new company be sued?
Potentially, if it knowingly participated in or benefited from the unlawful transfer of customers, contracts, revenue or confidential information.
3. Can an injunction stop customer diversion?
In suitable cases, an injunction may prevent the use of confidential information, company data, trademarks, payments or identified contracts.
4. Can the original company recover lost revenue?
It may seek compensation for proven lost profits, diverted payments, investigation expenses and other legally recoverable damage.
5. What evidence is most important?
Customer contracts, CRM records, emails, invoices, bank payments, pricing documents, customer notices and communications with the new company may be crucial.
6. Is a customer’s decision to leave automatically unlawful?
No. The claim usually depends on the partner’s conduct, such as deception, misuse of confidential data, unauthorized transfer or breach of a contractual restriction.
7. Can a foreign shareholder personally sue for diverted company revenue?
The company may be the primary claimant. The shareholder may need a corporate, derivative or separate direct claim depending on the loss and legal rights involved.
8. Can lost profits be calculated from diverted revenue?
Potentially, but the claimant must distinguish revenue from net profit and prove the causal connection between the diversion and the claimed loss.
9. Can the partner face criminal liability?
Potentially, if the evidence indicates fraud, forgery, misappropriation, unauthorized system access or another criminal offense.
10. How quickly should the company seek legal assistance?
Immediately. Delays may allow contracts, customers, funds and electronic records to move permanently to the new company.
