A European distribution company signs a supply agreement with a Turkish manufacturer, advances a six-figure payment, and discovers three months later that its counterpart is in active bankruptcy proceedings — proceedings that were publicly registered before the ink dried. This scenario plays out with regularity in Turkey's commercial landscape, where official records are accessible but fragmented across multiple registries, databases, and court systems that do not automatically cross-reference each other. Conducting thorough counterparty due diligence in Turkey requires coordinating searches across corporate legislation, insolvency law, civil procedure rules, and tax legislation simultaneously. This page explains how each layer works, what it reveals, and where the critical gaps lie for international business clients assessing Turkish partners, suppliers, debtors, or acquisition targets.
Turkey's approach to corporate disclosure is anchored in its commercial legislation, which imposes registration and publication obligations on commercial entities operating within the country. The primary registry is the Ticaret Sicili (Turkish Trade Registry), maintained by the Union of Chambers and Commodity Exchanges of Turkey (TOBB) and administered through regional chambers of commerce. Every limited liability company (limited şirket — Ltd. Şti.) and joint stock company (anonim şirket — A.Ş.) must register foundational documents, capital structure, and authorised signatories. Amendments — including changes in shareholding, management, registered address, and trade name — must be filed and published in the Türkiye Ticaret Sicili Gazetesi (Turkish Trade Registry Gazette), the official gazette for commercial announcements.
Under Turkey's corporate legislation, registered information is presumed known to third parties from the date of gazette publication. This presumption cuts both ways: it protects a diligent buyer who discovers adverse information through a proper search, and it may preclude a buyer from claiming ignorance when a problem was publicly disclosed. The practical implication is that any counterparty assessment must include a gazette search covering at least the past five years — not merely a point-in-time registry extract.
The online portal MERSİS (Merkezi Sicil Kayıt Sistemi — Central Registry Record System) consolidates Trade Registry data and allows electronic access to company information, including registered shareholders, board members, and authorised representatives. MERSİS extracts are the starting point for any Turkish due diligence exercise. However, practitioners consistently observe that MERSİS reflects only formally registered data. Beneficial ownership layers maintained through nominee structures, trust-like arrangements (inançlı işlem), or cascaded holding companies in offshore jurisdictions will not appear on the face of a MERSİS extract.
Turkey's beneficial ownership disclosure framework has been progressively strengthened through anti-money laundering legislation and regulations issued by the Financial Crimes Investigation Board (MASAK — Mali Suçları Araştırma Kurulu). Companies above defined thresholds must identify and disclose ultimate beneficial owners to MASAK. While this registry is not fully public, it becomes accessible in certain regulatory and judicial proceedings. When the commercial stakes are significant, counsel can advise on legitimate channels to access or verify MASAK disclosures as part of an enhanced due diligence process.
A complete Turkish company records search draws from at least four distinct official sources, each with a different scope and currency of information.
Trade Registry extract (MERSİS): Provides the company's founding date, legal form, registered capital, current shareholders and their ownership percentages, board of directors, authorised signatories, and registered address. It reflects the last registered state — which may be months behind the actual current state if a pending amendment has not yet been filed. Cross-checking the MERSİS extract against gazette publications identifies the gap between what was recently changed and what has not yet been formally registered.
Trade Registry Gazette archive: A chronological record of all published announcements for the company. Searching this archive reveals the full corporate history: capital increases and decreases, share transfers, mergers, spin-offs, prior bankruptcies, pledges over shares, and court-ordered attachments on company assets. A company with a history of frequent share transfers at nominal values — particularly around the time of a debt dispute — is a significant red flag under Turkish commercial litigation practice.
Tax authority records: Turkey's Revenue Administration (Gelir İdaresi Başkanlığı — GİB) maintains a public database of taxpayer status, including whether a company has been flagged as a fake invoicing entity (sahte belge düzenleyici), a category that carries severe consequences under Turkish tax legislation. A counterparty appearing on this list is operationally and reputationally compromised and may be subject to active tax audits or criminal investigations. This search takes minutes but is frequently omitted by international buyers relying solely on corporate registry data.
Chamber of Commerce records: Sector-specific chambers may hold additional information about membership standing, disciplinary proceedings, or commercial arbitration outcomes administered through chamber bodies. For companies in construction, textiles, or food sectors — where Turkish commercial disputes are particularly concentrated — chamber records add a layer of industry-specific intelligence.

Turkey's civil procedure rules vest jurisdiction over commercial disputes in specialised commercial courts (ticaret mahkemesi), general civil courts (asliye hukuk mahkemesi), and enforcement courts (icra mahkemesi). A counterparty may simultaneously be a defendant in a commercial court proceeding, a debtor in enforcement proceedings, and a respondent in a criminal investigation — each tracked in a separate system.
The National Judicial Network Project (UYAP — Ulusal Yargı Ağı Projesi) is Turkey's integrated court management system. Access to UYAP case files requires authorised credentials — typically held by registered Turkish attorneys. A Turkish lawyer with UYAP access can search active and completed cases by party name, tax identification number (vergi kimlik numarası), or central population registry number (T.C. kimlik numarası) for individual counterparts. This search reveals pending claims, enforcement proceedings, judgments against the company, and injunctions.
In practice, a single UYAP query does not capture all proceedings. Courts of different territorial jurisdictions maintain separate databases within the UYAP infrastructure. A creditor who obtained a judgment in İzmir enforcement court and a claimant pursuing the same entity in İstanbul commercial court may both be pursuing the same company without either case appearing in a single search. Thorough litigation screening requires queries across the jurisdictions where the company operates — typically the registered address court and the principal place of business court, which often differ.
Turkey's enforcement and bankruptcy legislation establishes two principal tracks for creditor action: ordinary enforcement proceedings (genel haciz yolu) and enforcement with or without a court judgment. The enforcement file system — maintained separately from court case files — is searchable through UYAP and reveals active seizure orders, attachment notices on bank accounts, and real estate encumbrances registered through the land registry (tapu sicili). A counterparty with multiple active enforcement files is a company under serious financial pressure, even if no formal bankruptcy petition has yet been filed.
Courts in Turkey have consistently held that knowledge of an enforcement proceeding, once properly served, binds third parties who acquire assets from the debtor after that date. This principle means that a buyer who closes a share acquisition without checking enforcement files may inherit successor liability for existing enforcement actions targeting company assets.
Turkey's insolvency legislation establishes two primary restructuring and liquidation procedures: bankruptcy proceedings (iflas) and concordat (konkordato), the latter serving as a court-supervised restructuring mechanism that was significantly expanded by legislative reform in 2018. A third mechanism — the restructuring through reconciliation (uzlaşma yoluyla yeniden yapılandırma) — applies to larger companies meeting specific thresholds.
Bankruptcy petitions in Turkey are filed with the commercial court at the debtor's place of business. Upon acceptance of a bankruptcy petition, the court issues a notice that is published in the Official Gazette (Resmî Gazete) and the Trade Registry Gazette. From the moment of publication, the bankruptcy is presumed known to all creditors and third parties. The bankruptcy estate is administered by a court-appointed trustee (iflas idaresi), and the debtor's capacity to enter into new transactions on behalf of the estate is immediately curtailed.
Concordat proceedings follow a different disclosure path. Upon a company filing for concordat protection, the commercial court first evaluates the file and, if satisfied that restructuring is feasible, issues a temporary injunction (geçici mühlet) — typically three months, extendable to one year. This temporary injunction is published in the Trade Registry Gazette and the Official Gazette. A company operating under a concordat injunction is legally protected from individual creditor enforcement actions during the injunction period, but it remains operational and may continue to enter into contracts. This creates a particular risk: an international supplier may conclude a new supply contract with a Turkish buyer that is already shielded by a concordat injunction, receive no payment, and then discover that enforcement against the buyer is blocked under insolvency law.
A concordat injunction does not appear in a standard Trade Registry extract. It requires a specific gazette search and a UYAP query. Companies under concordat protection are frequently not forthcoming about their status in commercial negotiations.
Due diligence practitioners in Turkey note that the period between a company's internal financial distress and its public disclosure through bankruptcy or concordat filings can span many months. During this window, the company may continue to solicit advance payments, sign new contracts, and create new obligations — all of which will rank as unsecured claims in subsequent insolvency proceedings. Identifying early warning indicators — tax debts appearing in GİB records, multiple enforcement files, share transfers to related parties at below-market values — allows a counterparty to identify insolvency risk before formal proceedings begin.
For clients acquiring Turkish companies or taking security over Turkish assets, insolvency avoidance rules under Turkish insolvency legislation create an additional risk layer. Transactions concluded in the period preceding a bankruptcy declaration — typically two years for transactions with connected parties and shorter periods for third parties — may be challenged by the bankruptcy trustee as fraudulent transfers or preferences. Pre-closing due diligence must therefore assess not only current solvency but the transaction history of the target over the relevant look-back period.

Understanding who actually controls a Turkish company often requires looking beyond the registered shareholder list. Turkish corporate legislation permits share transfers in limited liability companies through notarised deeds, which are then registered in the Trade Registry. Joint stock companies may issue bearer shares — though recent legislative amendments have significantly restricted this practice and required conversion to registered shares. The practical result is that current registered shareholder information in MERSİS should be current for most company types, but the economic beneficiary may still be obscured through holding layers.
A common structure in Turkey involves a domestic holding company (holding şirketi) as the registered shareholder, with the ultimate beneficial owner holding interests at the holding level. The holding company may itself be owned by individuals whose identity is disclosed only at the MERSİS level for that holding entity. Mapping a multi-tier ownership chain requires sequential registry searches at each corporate layer — a process that can involve three or four companies before reaching natural persons.
Where offshore entities — particularly from jurisdictions with limited public disclosure — appear in the ownership chain, direct registry access is unavailable. In these cases, practitioners in Turkey employ a combination of techniques: reviewing articles of association filed with the Trade Registry for shareholders' agreements or special voting rights that reveal control relationships; examining gazette publications for group transactions; analysing related-party disclosures in any publicly available financial statements (mandatory for companies above defined size thresholds); and cross-referencing individuals appearing in board compositions across affiliated companies.
Individual counterparts — whether personal guarantors, controlling shareholders, or proposed joint venture partners — are subject to a separate verification process. Turkish civil procedure rules and enforcement legislation allow creditors to pursue individual assets of company directors and shareholders in specific circumstances, including piercing the corporate veil where directors have conducted business with fraudulent intent or violated capital maintenance rules. Assessing this personal liability exposure requires checking the individual's involvement in prior bankruptcies, active enforcement files against them personally, and any criminal records accessible through judicial channels.
Legal specialists in Turkey point out that personal bankruptcy (iflâs of natural persons engaged in commercial activity) is handled through the same commercial court system as corporate insolvency and is equally searchable through UYAP. A proposed personal guarantor who is already bankrupt or subject to active enforcement proceedings provides materially weaker credit support than their apparent financial standing might suggest.
Related to ownership analysis is the question of connected-party transactions. Where a Turkish target company has historically conducted significant business with entities owned by the same beneficial owner — at pricing that deviates from arm's-length terms — Turkish commercial legislation and tax legislation both provide mechanisms to challenge or recharacterise those transactions. For M&A due diligence, identifying undisclosed related-party exposures is as important as establishing who the current owners are. See our analysis of M&A transactions in Turkey for a detailed treatment of how ownership structures affect transaction structuring and pricing.
The appropriate scope and depth of a Turkish counterparty investigation depends on the transaction type, the commercial exposure, and the time available before signing.
Scenario 1 — New supply contract with advance payment obligation. A European buyer is asked to pay 40% of a contract value upfront to a Turkish supplier it has not previously dealt with. A minimum viable check — taking three to five business days — covers: MERSİS extract, a five-year gazette search, GİB taxpayer status, and a UYAP litigation search at the supplier's registered address court. This scope identifies active bankruptcy, concordat protection, major pending judgments, and fake-invoice status. If the advance payment is material, a land registry search on the supplier's assets and an enforcement file check add one to two additional business days. The cost of this scope starts from the low thousands of euros in legal fees and can prevent an unrecoverable advance loss.
Scenario 2 — Taking personal guarantees from Turkish shareholders. A lender extending credit to a Turkish company requires personal guarantees from its two principal shareholders. Beyond the corporate-level checks, the due diligence must establish each individual's solvency, existing enforcement exposure, prior bankruptcies, and real asset position. Individual asset searches require UYAP queries by T.C. identity number, land registry searches by name, and vehicle registry checks. This enhanced scope typically requires seven to ten business days and access to UYAP through a licensed Turkish attorney. A guarantor who appears solvent on paper but carries multiple enforcement files and has transferred real estate to family members in the preceding two years provides substantially weaker security than a clean guarantor profile.
Scenario 3 — Acquisition of a Turkish operating company. A strategic buyer is acquiring a Turkish manufacturer with operations in two cities. Full pre-closing due diligence spans corporate records across both registered locations, a complete litigation search in all relevant court districts, insolvency checks including concordat history, MASAK beneficial ownership verification, tax liability confirmation with the Revenue Administration, labour court claims (a separate track under Turkey's employment legislation), and ownership chain analysis through two holding layers. This scope realistically takes three to four weeks with a local Turkish legal team. The critical outputs are a clear map of contingent liabilities, a confirmed beneficial owner identity, and a verified absence of undisclosed insolvency proceedings. For the regulatory aspects of such transactions, see our overview of corporate disputes in Turkey.
Turkish counterparty due diligence of the type described on this page is applicable and advisable where one or more of the following conditions are met:
Before initiating the due diligence process, verify that the following baseline information has been obtained from the counterparty: full legal name and tax identification number (vergi kimlik numarası); registered address and date of incorporation; legal form (Ltd. Şti. or A.Ş.); names of current directors and authorised signatories; and — for individual counterparts — T.C. identity number. Without these identifiers, UYAP and registry searches cannot be reliably run.
A non-obvious risk at this stage: Turkish companies frequently operate under a trade name (ticari işletme adı) that differs from the registered legal name. Contracts signed using only the trade name, without the full legal entity name and tax number, create enforcement difficulties if the counterparty later disputes which entity is bound. Confirming legal identity before contract execution is itself a due diligence function.
The decision to expand from a standard records check to a full enhanced due diligence scope is triggered by any of the following: enforcement files found in a preliminary search; recent share transfers at below-market value; a concordat or bankruptcy entry in the last three years; a GİB fake-invoice flag; nominee shareholders without traceable beneficial owner identity; or disclosed but unexplained related-party transactions exceeding a significant share of annual revenues. Each trigger warrants a specific additional investigation module rather than a wholesale escalation of the entire exercise.
For international clients assessing cross-border enforcement prospects — including how a Turkish judgment or arbitral award obtained against an insolvent entity interacts with insolvency proceedings — Turkey's arbitration legislation and civil procedure rules governing recognition of foreign judgments both impose procedural requirements that must be assessed in parallel with the counterparty investigation. Mapping these intersections early prevents strategy misalignment later in the engagement.
Q: How long does a standard counterparty due diligence check in Turkey typically take?
A: A baseline check covering MERSİS records, a five-year gazette search, GİB taxpayer status, and a UYAP litigation query at the counterparty's registered address court can be completed in three to five business days with a licensed Turkish attorney and UYAP access. Enhanced investigations — including multi-district litigation searches, enforcement file checks, land registry searches, and beneficial ownership tracing across holding layers — typically require two to three weeks. Timeline depends heavily on the number of company layers in the ownership structure and the geographic spread of the counterparty's operations.
Q: Is it true that Turkey's Trade Registry is fully public and anyone can check a company's owners online?
A: The MERSİS portal provides public access to registered shareholder and director data, and this is an important starting point. However, the registered shareholder is frequently a holding company rather than an individual beneficial owner, and the portal reflects only formally registered changes — not pending amendments or informal arrangements. Gazette searches, UYAP litigation access, and MASAK beneficial ownership registers require additional steps beyond the public portal and, in the case of UYAP, require a licensed Turkish attorney. Relying solely on a MERSİS extract to assess counterparty risk is a common mistake with potentially serious commercial consequences.
Q: Can a Turkish company enter into binding contracts while under concordat protection?
A: Yes — a company under a Turkish concordat injunction retains its legal capacity to enter into contracts and conduct ordinary business operations during the protection period. The injunction suspends individual creditor enforcement actions, not the company's ability to transact. This means a supplier or service provider may conclude a new agreement with a concordat-protected company in good faith, deliver its obligations, and then find that it cannot enforce payment through ordinary enforcement channels during the injunction period. Identifying concordat status before contracting — through a gazette search and UYAP check — is the only reliable safeguard.
