Fiona Sinclair QC


Professional indemnity work concerning lawyers (both solicitors and barristers) forms a substantial part of Fiona's practice. Notable examples include:

  • Advising solicitors on a claim by professional indemnity insurers relating to the conduct of the defence of a claim against the insured
  • Advising the SRA’s Assigned Risks Pool on the defence of claims relating to a multi-occupancy buy-to-let development
  • In the Concord Street Litigation, multiple purchasers allege negligence in relation to building insurance against multiple firms of solicitors and claim under the Defective Premises Act against the design and build contractor of a residential development. Fiona acts (leading Katie Powell of 4 New Square) for the largest group of solicitor defendants. It is unusual for there to be such a large number of parties on both sides of a case: it poses significant case management and procedural challenges.
  • In the Lovell House Litigation, the same legal teams act for claimants making similar allegations in relation to another residential development. Again, Fiona acts for the largest group of solicitor defendants. 
  • Fiona defended specialist construction law solicitors against a claim by the developers of three residential estates in the UK.
  • Fiona defended solicitors against a claim by an offshore property company which purchased a highly prestigious London residential property; and in related contribution proceedings. Difficult issues as to scope of duty, causation and assessment of damages
  • Acting for solicitors in a claim concerning the introduction of a client to an overseas investment opportunity. It culminated in the solicitors taking over the client's action against two overseas insurance companies, which defended the action (unsuccessfully) on the grounds of fraud by the solicitors.
  • Acting for solicitors in a £multi-million fraud claim; ultimately discontinued against Fiona’s clients with indemnity costs.
  • Haydon-Baillie and Ors v Bank Julius Baer [2007] EWHC 1609 (Ch) and [2007] EWHC 3247 (Ch). Acting for solicitors in multi-party litigation concerning the title to the UK’s largest stately home and its contents. This case involved issues of conversion law and of a mortgagee’s duty to the mortgagor.
  • NM Rothschild & Sons Ltd v. Berenson [1997] NPC 15 (CA), a claim against solicitors concerning a line of credit for property finance.

Fiona is a member of both the Commercial Bar Association and the Chancery Bar Association.
