Commercial Litigation — Our Services
Professional Negligence
Specialising in the financial, accounting and legal sectors, we have extensive experience of bringing and defending claims for professional negligence.

Clients include high-net-worth individuals, partnerships and companies, and we’ve acted across disputes – ranging from breach of professional duty to fraud and breach of contract.

Drawing on our deep in-house expertise, we assess each case with precision. Identifying weaknesses and leveraging strengths, to build commercially-sound cases for our clients.
