In his own words:

“Rory Spillman is a rising star of the London litigation landscape. He has a thoughtful and creative approach with a keen eye for detail and the wider tactical considerations at play. He is always fighting with his troops in the trenches rather than giving orders from on high.”

– The Legal 500 UK 2026

Rory is a Partner at Signature’s London office specialising in commercial and banking litigation.

With over 12 years’ experience, Rory represents institutions, corporates, private equity firms, high-net-worth individuals, and financial entities from varying jurisdictions, focussing on complex and high value commercial and banking disputes. Rory represents clients in the High Court, Court of Appeal and the Supreme Court.

Rory has significant experience in representing large numbers of claimants in group claims against financial institutions, including claims pursuant to s. 90 and 90A Financial Services and Markets Act 2000.

Rory also represents clients in complex shareholder and partnership disputes, including claims in relation to alleged breaches of fiduciary duties and subsequent accounts of profits.

In addition to the above areas, Rory also represents and advises clients on white-collar regulatory investigations. His experience covers FCA investigations and interviews, Upper Tribunal proceedings, and advising individuals with respect to investigations into them and their employers. This includes advising and working with legal teams in other jurisdictions (including the US) in the wider context of multi-jurisdictional regulatory, criminal and civil investigations, including SEC and DOJ proceedings.

The size, nature, importance and complexity of Rory’s cases is reflected in the fact that they often run for many years as they progress through their procedural stages, including with respect to liability, quantum and where appropriate the appellate Courts. Rory’s cases often raise novel are cutting-edge issues.

In 2024, Rory was appointed to the committee of The Collective Redress Lawyers Association, which provides a forum to gather together specialist legal practitioners in the field of collective redress in order to advocate for reform. It also facilitates dialogue and the sharing of best practice among the broad range of those involved in group litigation, including civil society, consumer rights groups, academics and funders.

Rory is recommended for Commercial Litigation in The Legal 500 UK 2026 Guide, where he is described as “a thoughtful and highly intelligent lawyer who goes the extra mile.” Previous editions of the Guide described him as a “natural leader”, “unflappable, even under immense pressure” and as producing “consistently high quality work“, with a “real eye for making sure that the detail is right.” One commentator has also noted that Rory has “tremendous judgement” is “very hard-working“, and comes “highly recommended for banking disputes.” He has also been described by previous Guides as “impressive“, “excellent” and a “real authority.”

Prior to joining Signature Litigation, Rory qualified in 2012 after training at Hogan Lovells. Whilst with Signature and at his previous firm, Rory has worked on a number of high profile cases concentrating on banking and multi-jurisdictional commercial disputes and regulatory investigations.
