4 Pump Court has an unparalleled reputation for excellence in professional negligence disputes.

Outstanding written and oral advocacy is at the heart of 4 Pump Court’s entire practice and nowhere more so than in professional negligence disputes. But while we are renowned for our advocacy skills, we also recognise that securing excellent outcomes for our clients starts long before any final hearing. In fact, it often means avoiding litigation or arbitration altogether to achieve a commercially sensible result. We provide sound, commercial advice and meticulous drafting from the earliest stages of pre-action procedures all the way through to final determination or settlement. We bring technical knowledge and a commercial approach to every case, whatever its size.

We recognise that insurance is a key economic driver for professional liability dispute resolution. The strength of our Insurance & Reinsurance practice means that we can bring to our professional liability disputes an in-depth understanding of the insurance policy interpretation and coverage issues that shape the outcomes of such disputes across the full range of relevant policies: public liability, material damage, financial loss, project, CAR and professional indemnity.

Our professional negligence dispute experience spans a wide range of sectors including energy, construction, engineering, infrastructure and information technology. We act in domestic and international disputes for:

  • Architects
  • Design and build contractors
  • Engineers and surveyors of all disciplines
  • Information technology consultants and contractors
  • Legal professionals including solicitors and barristers
  • Project managers and other property professionals
  • Specialist subcontractors

Our experience has led members of Chambers to act for professionals all over the world, including in international arbitration, overseas litigation and an appeal to the Privy Council.
