Turkish Guarantors in English-Law Financings: Suretyship Formalities, Spousal Consent and Enforcement
Corporate & Commercial

Turkish Guarantors in English-Law Financings: Suretyship Formalities, Spousal Consent and Enforcement

Loans arranged in London for Turkish groups are usually governed by English law, but the guarantees behind them come from Turkish companies and founders whose assets are in Türkiye. Turkish law asks for a handwritten maximum amount, a signature on paper and, for a married individual, the spouse's prior written consent. It also restricts guarantees within corporate groups. A guarantee that is valid in London can still fail where the money is.

Building Ships in Türkiye under English Law: Newbuilding Contracts, Refund Guarantees and Yard Insolvency

Most newbuilding contracts with Turkish shipyards are governed by English law and refer disputes to London arbitration, and the buyer's instalments are secured by a refund guarantee from a Turkish bank. The contract is decided in London, but the hull, the yard and usually the bank are in Türkiye. A buyer's protection depends on a guarantee that can be called and collected without the help of a Turkish court, and on knowing which questions Turkish law answers whatever the contract says.

English Trusts and Turkish Forced Heirship: Reserved Shares, Reduction Actions and Where the Assets Sit

An English trust does not take assets beyond the reach of Turkish forced heirship as a matter of course. A Turkish court applies Turkish succession law to a Turkish citizen and can reduce lifetime transfers that encroach on the reserved shares of a spouse, descendants or parents. An English court will usually uphold a valid lifetime trust of English assets. The result turns on which court decides, where each asset is and how the trust was made.

Parallel Proceedings Between Istanbul and London: Anti-Suit Injunctions, Lis Pendens and the Race to Court

When a Türkiye–UK dispute is brought before courts in both countries, neither is obliged to give way. Turkish courts do not treat a pending English case as lis pendens, while English courts may order a party to stop Turkish proceedings brought in breach of a London arbitration or jurisdiction clause. The outcome usually turns on the clause, on where each party can be reached and on what is done in the first few weeks.

English-Law Debt and Turkish Restructurings: Concordat, Restructuring Plans and the Rule in Gibbs

A confirmed Turkish concordat binds creditors in Türkiye, but under the rule in Gibbs it does not discharge a debt governed by English law. For Turkish companies with English-law loans, bonds or guarantees, a restructuring that holds in both countries usually needs an English-law mechanism alongside the Turkish one, and evidence that each order will be recognised where the assets are.

Electronic Bills of Lading in Türkiye–UK Trade: Possession, Control and Misdelivery

English law now allows qualifying electronic bills of lading to perform legal functions traditionally dependent on possession of paper. In Türkiye–UK trade, however, the carriage contract, the electronic document, proprietary rights in the cargo, the delivery obligation, the financing structure and the P&I position may still engage different legal regimes.

Merger Control in Türkiye: Control, Notification, Technology Transactions and Closing Risk

Turkish merger control turns on more than transaction value or shareholding percentage. A transaction must first amount to a lasting change of control, after which turnover, technology-sector rules, joint ventures, cross-border effects and closing mechanics determine whether Competition Board clearance is required. This briefing examines the 2026 regime from transaction structuring through clearance and closing.

Northern Cyprus Title Deeds: What Turkish, Exchange and Allocation Titles Actually Mean

Turkish title, Exchange or Eşdeğer title and Allocation or Tahsis title are the three descriptions most often used in the Northern Cyprus property market. They describe how the present title arose. They are not three statutory grades of legal quality, and they are no substitute for examining the register. This briefing considers the domestic title framework under Article 159 and Law No. 41/1977, the Immovable Property Commission, the European case law, the foreign-purchase regime and the due diligence a buyer needs before relying on a koçan.

Ship arrest is the specialised security remedy that preserves the practical value of a maritime claim while an arrestable asset remains within reach. This briefing explains maritime claims and liens, which ship may be arrested, sister-ship and associated-ship questions, applicant security, release against P&I security, wrongful-arrest risk, priority and cross-border enforcement under Turkish law.

Public Procurement, Tender Challenges and Bid Exclusion Strategy: The Legal Fight Before the Contract Is Signed

A public tender is often lost before anyone reads the price. One expired certificate, one defective guarantee, one unclear consortium document, one late objection or one misunderstood exclusion ground can remove a capable bidder from the process. Public procurement is not ordinary sales, it is a legal procedure with commercial consequences. This briefing explains how contractors, suppliers, investors and international bidders should treat the tender file as evidence, and fight the procurement contest before the contract exists, in Türkiye and the United Kingdom.

Professional Negligence, Advisor Liability and Professional Indemnity Insurance: When the Advice Becomes the Dispute

Professional negligence is not simply a complaint that advice went wrong. It is a disciplined inquiry into what the professional was asked to do, what risk they took responsibility for, what was said, what was omitted, what the client did in reliance, and whether the loss that followed is legally recoverable. A poor outcome is not always negligence, a mistake is not always causation, and a professional indemnity policy is not always a cheque. This briefing explains how businesses, professionals and insurers should think about advisor-liability disputes before the file becomes a claim.

Work Permits, Employer Sponsorship and Cross-Border Mobility: The Legal Status Behind International Growth

International companies often move people before they move the legal structure. A founder flies in to open the office. A foreign shareholder starts managing staff. A director signs contracts locally. A group employee arrives for meetings and slowly becomes part of the operation. In cross-border employment, the commercial role, corporate title, payroll route and legal right to work must tell the same story. This briefing explains how employers, founders, foreign investors and international groups should think about work authorisation, sponsorship and mobility risk in Türkiye and the United Kingdom before the business commits.

Letters of Credit, Demand Guarantees and Trade Finance Disputes: When Documents Control the Money

In trade finance, the bank does not usually pay the story. It pays the documents. Letters of credit, demand guarantees, standby credits and performance bonds can make international trade faster and more bankable, but they can also turn a small documentary mistake into non-payment, an aggressive bond call into immediate cash loss, or a shipping discrepancy into a full commercial dispute. This briefing explains how exporters, importers, contractors, banks and insurers should think about the instruments before the money moves.

Warranties, Indemnities and Disclosure Letters in Cross-Border M&A: Where the Deal Really Allocates Risk

Due diligence identifies risk. The share purchase agreement decides who lives with it. In cross-border M&A, warranties, indemnities, disclosure letters, limitation clauses, escrow and W&I insurance are not boilerplate. They are the legal machinery by which uncertainty becomes price, liability or leverage. This briefing explains how buyers, sellers, founders and investors should think about risk allocation before, during and after signing.

Cross-Border Fraud, Asset Tracing and Freezing Strategy: Recovering Value Before It Disappears

In cross-border fraud, the first question is often not where to sue but where the money went. Funds move through accounts, jurisdictions, structures and substitute assets before a claimant has organised the file, so the legal response must protect evidence, trace assets, create pressure and preserve recovery options before value moves beyond reach.

Hotels, Serviced Apartments and Short-Term Accommodation: The Legal Risk Behind the Guest Experience

A room is not legally neutral once a paying guest sleeps in it. The same apartment may be a private residence, a long-term rental, a serviced apartment, a short-term let, an aparthotel unit or hotel accommodation depending on how it is used, marketed, managed and occupied, and each model carries a different legal risk. The mistake is to treat hospitality as property income with better photographs. Accommodation is a regulated, guest-facing business: licensing, fire safety, insurance, platform rules, building consent, data, staff, neighbour complaints and management agreements all sit behind the guest experience. This briefing maps that risk for owners, operators and investors in Türkiye and the United Kingdom.

An insurer can pay a perfectly valid policy claim and still find recovery restricted by a liability cap, an expired limitation period, an arbitration agreement, missing evidence or a release the insured already gave. This briefing examines statutory subrogation under Articles 1472 and 1481 of the Turkish Commercial Code, preservation of recovery rights during adjustment, limitation and jurisdiction, partial indemnification, contractual risk allocation, multi-party losses and cross-border enforcement.
