Foreign Co-Founder Dispute in a Turkish Startup: Legal Solutions and Exit Options (2026 Updated Guide)

Foreign co-founder dispute in a Turkish startup? Learn about shareholder rights, deadlock, dilution, director removal, IP ownership, share transfers, buyouts, injunctions and exit strategies in Turkey.

A dispute between co-founders can threaten the survival of a startup, particularly where one founder is a foreign investor and the company operates under Turkish law. Conflicts commonly arise over management control, funding obligations, dilution, access to company information, intellectual property, founder salaries, unauthorized spending, investor negotiations, share transfers or attempts to remove one founder from the business. When the relationship breaks down, the foreign co-founder should not focus only on whether they can “leave the company.” The first questions should be who legally controls the company, what rights attach to the shares, who owns the startup’s assets and intellectual property, whether company value is being transferred elsewhere, and which exit strategy protects the founder’s economic interest.

Why Do Co-Founder Disputes Arise in Turkish Startups?

Startup disputes often begin informally. Two or three founders create a business based on trust, divide responsibilities verbally and postpone detailed legal arrangements until investment arrives. Problems emerge when the company begins generating revenue or requires additional financing.

Typical disputes involve unequal workloads, disagreements over strategy, founder compensation, ownership percentages, new investors, control of bank accounts, intellectual property, customer relationships and allegations that one founder is using company resources for personal purposes.

Start With the Company’s Legal Structure

The first step is determining the legal form of the Turkish company. Shareholder rights, management powers, transfer procedures and exit mechanisms differ depending on whether the startup operates as a joint-stock company, limited-liability company or another structure.

The foreign founder should collect the articles of association, shareholders’ agreement, share records, general assembly resolutions, management or board resolutions and relevant investment documents.

Review the Shareholders’ Agreement

A shareholders’ agreement may contain important provisions concerning reserved matters, voting rights, board representation, founder obligations, vesting, share transfers, drag-along and tag-along rights, deadlock procedures, non-compete obligations, confidentiality and exit mechanisms.

However, contractual rights and rights enforceable through the company’s corporate structure should be analyzed separately.

Determine the Foreign Founder’s Actual Shareholding

Do not rely solely on an informal understanding that the founders own the startup “50/50” or “one-third each.”

The legal records should be examined to determine the founder’s actual ownership position and whether subsequent capital increases, share transfers or investment rounds changed that percentage.

What Happens in a 50/50 Founder Deadlock?

A 50/50 structure can become particularly difficult when neither founder can obtain the votes required for important decisions. The company may become unable to approve financing, appoint management, enter major contracts or make other strategic decisions.

The shareholders’ agreement and articles should first be reviewed for a deadlock mechanism.

Can the Majority Founder Control Everything?

Not necessarily. Majority ownership can provide substantial voting power, but it does not create unlimited authority to disregard corporate rules, minority rights or the interests of the company.

The legality of each action depends on the corporate structure, articles, voting requirements and nature of the transaction.

Can a Foreign Co-Founder Be Excluded From Management?

Ownership and management are separate concepts. A founder may potentially lose a management position while retaining shares, depending on the company’s structure and applicable procedures.

Removal from management does not automatically eliminate shareholder rights.

Removal From Management Does Not Mean Loss of Shares

This distinction is critical. A foreign founder who is removed as a director, manager, employee or authorized signatory should immediately determine which rights have actually been affected.

The founder may still retain economic, voting, information and other shareholder rights.

Access to Company Information Can Become a Major Dispute

A founder who is excluded from management may suddenly lose access to accounting systems, contracts, bank records or corporate information.

Applicable shareholder information and inspection rights should be evaluated promptly. Evidence requests should be documented rather than handled only through informal messages.

Preserve Corporate Evidence Immediately

Once a serious founder dispute begins, preserve legally accessible copies of corporate resolutions, agreements, correspondence, financial information, capitalization records, investment documents and intellectual-property records.

Do not unlawfully access accounts or systems simply because you previously had technical access.

Unauthorized Bank Transactions Should Be Investigated

If one founder is transferring company money without proper authorization, identify who holds bank-signing authority and whether the payments have a legitimate corporate basis.

Preserve bank statements and supporting accounting records where lawfully accessible.

Company Money Is Not Founders’ Personal Money

A shareholder cannot generally treat corporate assets as personal property merely because they own a substantial percentage of the business.

Personal expenses, related-party transfers and unexplained withdrawals can therefore create corporate and potentially wider legal consequences.

Related-Party Transfers Require Close Review

A founder may attempt to move revenue, contracts or assets to another company controlled by that founder.

Examine transactions involving affiliated companies, relatives, newly established businesses and entities sharing employees, customers or intellectual property with the startup.

Customer Diversion Can Destroy Startup Value

One of the most serious disputes arises when a founder directs customers or new contracts away from the startup.

Preserve customer correspondence, proposals, invoices and other evidence capable of showing whether business opportunities were diverted.

Intellectual Property Ownership Must Be Established

For technology startups, the most valuable assets may be software, source code, trademarks, domains, designs, databases or algorithms.

Determine whether those assets legally belong to the company, an individual founder, employees or an external contractor.

A Founder Writing the Code Does Not Automatically Resolve Ownership

The legal position depends on the relevant agreements and circumstances. Review employment, founder, assignment, development and contractor agreements.

This should be done before negotiating the value of an exit.

Domain Names and Digital Accounts Matter

Control over the startup’s domain, cloud services, repositories, social accounts and payment infrastructure can become a practical weapon during a founder dispute.

Map the accounts and determine the legal owner and authorized users.

Do Not Retaliate by Locking the Other Founder Out

Unilateral password changes, deletion of files or disabling business systems can escalate the dispute and damage the company.

Emergency protection should be pursued through legally defensible corporate or judicial measures where necessary.

Dilution Can Become a Major Risk

A foreign co-founder may discover that a capital increase is being proposed that would substantially reduce their percentage.

The founder should immediately examine the legal basis of the capital increase, voting procedure, participation rights and investment terms.

Can the Majority Dilute the Foreign Founder?

A dilution dispute requires careful analysis of corporate law, articles, shareholders’ agreements and the particular capital transaction.

A capital increase should not automatically be treated as unlawful merely because ownership percentages change, but abusive or procedurally defective transactions may be challengeable.

Review Pre-Emptive and Participation Rights

Existing shareholders may have rights relevant to new share issuances. The precise rights depend on the company’s structure and transaction.

A founder should not ignore a capital-increase notice simply because litigation is already underway.

Founder Vesting Can Complicate the Exit

Startup agreements increasingly use vesting, good-leaver and bad-leaver mechanisms.

Determine whether these provisions are legally effective in the specific structure and whether the triggering event actually occurred.

Bad-Leaver Allegations Should Be Challenged Carefully

A founder may be accused of misconduct shortly before an exit to justify acquiring their shares at a reduced price.

Examine the contractual definition, evidence, procedure and valuation consequences before accepting the classification.

Employment and Shareholder Rights Are Separate

A founder may simultaneously be a shareholder, board member and employee.

Termination of employment does not necessarily terminate share ownership. Each legal relationship should be analyzed separately.

Can the Foreign Founder Sell Their Shares?

Potentially, subject to the company’s legal form, articles, contractual restrictions and applicable transfer procedures.

Before negotiating with a third-party buyer, review rights of first refusal, consent requirements, transfer restrictions, tag-along provisions and other contractual obligations.

A Forced Sale Should Not Be Accepted Without Valuation

A founder facing pressure to exit should understand the value of the company and their shares before agreeing to a price.

Startup valuation may involve revenue, intellectual property, recurring customers, financing rounds, cash, liabilities and future commercial prospects.

Review the Latest Investment Round

A recent investment can provide important valuation information, although the economics of preferred and ordinary shares may differ.

The headline company valuation should not automatically be treated as the cash value of every founder’s shares.

Share Classes Can Affect Exit Value

Different share classes may have different voting, liquidation or economic rights.

Review the company’s capital structure and investment agreements before calculating the foreign founder’s exit value.

Shareholder Loans Must Be Separated From Equity

A foreign founder may have financed the startup through both equity and shareholder loans.

A share sale should not automatically be assumed to settle outstanding loans. Identify each debt separately.

Unpaid Founder Compensation Should Also Be Reviewed

Salary, consultancy fees, expense reimbursements, bonuses and other claims may exist independently of the value of the shares.

A comprehensive settlement should identify which claims are being released.

Negotiated Buyout Is Often an Important Exit Option

Where continued cooperation is impossible, one founder may purchase the other’s shares.

The agreement should address price, payment security, representations, liabilities, intellectual property, confidentiality and future competition.

Installment Payments Create Collection Risk

If the purchase price will be paid over time, consider appropriate security mechanisms.

A founder should be cautious about transferring complete ownership before receiving adequate protection for deferred payments.

Tag-Along Rights Can Protect Minority Founders

If the controlling shareholder sells shares to an investor, a tag-along provision may allow another shareholder to participate in the sale under specified conditions.

Review the exact contractual wording and triggering transaction.

Drag-Along Rights Can Force an Exit

A properly structured drag-along provision may potentially require minority shareholders to participate in a company sale.

The triggering conditions, required majority, sale terms and procedural requirements should be examined carefully.

Investor Negotiations Can Trigger Founder Conflicts

One founder may negotiate financing without adequately informing the other.

Review term sheets, convertible instruments, option arrangements and investment documents to determine whether the transaction affects governance or dilution.

Convertible Instruments Require Special Attention

Startup financing may include instruments that convert into equity later.

A founder should model the fully diluted capitalization rather than focusing only on the current registered ownership percentage.

Unauthorized Guarantees Can Create Company Risk

A founder or director may attempt to provide guarantees or security for related businesses.

Examine whether the person had authority and whether the transaction served the company’s legitimate interests.

General Assembly Decisions May Be Challengeable

Where disputed decisions are adopted through a shareholder meeting, examine notice, agenda, quorum, voting, conflict-of-interest and other procedural requirements.

Potential remedies and deadlines should be assessed immediately.

Board or Management Decisions Should Also Be Reviewed

Not every dispute concerns shareholder resolutions. Management decisions may themselves be challenged or give rise to liability depending on the circumstances.

Preserve the relevant resolutions and authority records.

Falsified Minutes Require Immediate Action

If a foreign founder believes minutes or signatures were fabricated, preserve authentic signature samples, electronic correspondence and corporate records.

False corporate documentation can transform an ordinary shareholder dispute into a substantially more serious matter.

Can an Injunction Be Obtained?

Depending on the facts and legal requirements, interim judicial protection may potentially be considered where waiting for a final judgment could cause serious or irreversible harm.

The requested measure should be specific and supported by evidence.

When Is Emergency Relief Particularly Important?

Urgency may arise where assets are being transferred, shares are about to be disposed of, intellectual property is being moved, bank funds are disappearing or a disputed corporate transaction is about to become difficult to reverse.

Delay can materially reduce the effectiveness of legal remedies.

Can Company Assets Be Frozen?

Whether a particular protective measure is available depends on the nature of the claim, evidence and procedural requirements.

The remedy should be tailored to the actual risk rather than seeking unnecessarily broad restrictions.

Mediation Can Be Useful in Founder Disputes

Founder disputes are often commercially suitable for negotiated resolution because both sides may benefit from preserving company value.

A structured settlement can resolve ownership, management, IP, debts and future competition in a single transaction.

Settlement Should Cover More Than the Share Price

A complete exit agreement may need to address shares, shareholder loans, employment claims, intellectual property, customer relationships, confidentiality, non-disparagement, pending litigation, tax matters and mutual releases.

Incomplete settlements frequently create a second dispute.

Foreign Founders Should Consider Immigration and Work Status Separately

A foreign founder’s company dispute can also affect practical arrangements connected with their role in the business. Corporate ownership, management authority and employment status should therefore be distinguished carefully from any separate immigration or work authorization issues.

International Shareholders May Face Jurisdiction Questions

A shareholders’ agreement may contain arbitration or foreign jurisdiction clauses while certain corporate disputes remain connected with mandatory Turkish corporate procedures.

The dispute-resolution clause should be analyzed before proceedings begin.

Arbitration May Be Relevant

Where the shareholders’ agreement contains a valid arbitration clause, contractual founder disputes may potentially fall within arbitration.

However, the scope of the clause and the precise corporate remedy sought should be examined carefully.

Evidence From WhatsApp and Email Can Matter

Founder relationships are frequently documented through messages rather than formal resolutions.

Preserve relevant electronic communications in their original context. Isolated screenshots should not be relied upon where complete conversation records are available.

Foreign Investors Should Avoid Informal Resignation

A founder under pressure may send a message saying they “quit.”

Before resigning from management, employment or another position, determine exactly which legal role is being surrendered and how the resignation affects leverage in the wider dispute.

Do Not Sign a Broad Release Without Reviewing It

Exit documents may contain broad releases covering unknown claims, shareholder loans, compensation, IP or director liability.

Every release should be reviewed against the complete relationship between the founder and the company.

2026 Strategy for Foreign Co-Founder Disputes

Foreign founders should approach startup disputes as a combination of corporate control, asset protection, evidence preservation and exit valuation. The strongest strategy is usually to establish the founder’s exact legal position before negotiating.

Lawyer Fırat Fesih Kaya recommends that foreign investors first reconstruct the corporate record, capitalization table, management authority, financial transactions and intellectual-property ownership. Only after these issues are clear should the founder decide whether the objective is restoring management rights, preventing dilution, challenging transactions, negotiating a buyout or pursuing a complete exit.

Frequently Asked Questions

Can a Turkish co-founder remove a foreign founder from the company?

Removal from a management or employment position does not automatically eliminate share ownership. The exact corporate and contractual structure must be reviewed.

Can a majority shareholder make every decision alone?

Not necessarily. Voting requirements, minority protections, corporate procedures and contractual restrictions may limit majority power.

What can a foreign founder do if company information is withheld?

Applicable shareholder information and inspection rights should be evaluated, and formal requests may be necessary.

Can a founder’s shares be diluted?

Capital increases can change ownership percentages, but the legality of the transaction depends on corporate procedures, shareholder rights and the specific circumstances.

Can a foreign founder sell shares to another investor?

Potentially, subject to statutory requirements, articles of association and contractual transfer restrictions.

What if another founder transfers customers to a new company?

The transactions, corporate duties, contracts and evidence should be reviewed immediately. Urgent legal protection may be relevant where company value is being diverted.

Who owns software developed by a founder?

Ownership depends on the relevant legal relationship and agreements. The founder’s role, development arrangements and any assignment provisions should be examined.

Can a court stop a disputed share or asset transfer?

Depending on the claim, evidence and urgency, interim judicial protection may potentially be available.

Is mediation possible in a co-founder dispute?

Yes. A negotiated buyout or structured separation can often preserve more company value than prolonged litigation, provided the settlement protects all relevant rights.

What should a foreign founder do first when the relationship collapses?

Secure the corporate evidence and determine the exact shareholding, voting rights, management authority, financial position and ownership of the startup’s key assets before resigning, selling shares or signing any settlement document.
