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

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.

Franchise, Licensing and Brand Expansion in Türkiye: When Growth Becomes Control Risk

A franchise is not only a way to grow faster. It is a decision to let another business operate under your name, use your system, speak to your customers and create legal consequences the market will still associate with you. This briefing explains how brands, founders, investors and international businesses should think about franchise agreements, licensing, operational control, royalties, competition risk, termination and brand protection in Türkiye and cross-border markets.

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.

Directors' Duties, D&O Insurance and Board Crisis Strategy: When Limited Liability Stops Feeling Limited

Limited liability protects companies. It does not make directors invisible. When a business enters crisis, decisions that once looked commercial may later be examined as duties, conflicts, wrongful trading, insurance notifications or evidence. This briefing explains how directors, founders, investors and family businesses should think about board liability, D&O insurance and crisis strategy before pressure becomes personal.

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.
