About Us

FS Litigation is a leading law firm specialising in high value, complex litigation and dispute resolution.

FS Litigation was founded as a conflict-free specialist litigation practice. From our earliest cases to our current work leading some of the UK’s largest and most complex disputes, our ethos has remained constant: clarity of purpose, technical excellence, and unwavering commitment to our clients.

We are ranked in the top tier of Chambers & Partners and The Legal 500 for litigation. Clients, opponents, and peers recognise us for our ability to handle heavyweight claims and our reputation for controlled, decisive litigation.

We are deliberately independent and conflict-free. Unlike most large commercial firms, we do not act for banks, insurers, or other major institutions. This gives us a unique freedom to act for claimants against them, bringing cases that other firms cannot.

Our partner-led team has acted in many of the country’s most challenging disputes — from professional negligence claims against global accounting firms, to group actions on behalf of thousands of investors and pension holders, to high-value commercial litigation for corporates and entrepreneurs. We combine technical precision with litigation instinct, always focused on achieving the best possible outcome for our clients.

Many of the disputes in which we act have an international dimension. We work closely with a network of leading overseas firms and experts to deliver joined-up cross-border strategies where required.

Top ranked in both Chambers & Partners and Legal 500, FS Litigation is acknowledged by the leading legal directories and praised by clients for our technical strength and fearless approach. The firm is widely regarded as one of the UK’s leading litigation boutiques.
