When You Need This

Our Approach

  1. Joint or court-directed instructions and scope agreement with both parties.
  2. Independent review of disclosed financial and medical material.
  3. Neutral loss quantification with reasoned assumptions on disputed issues.
  4. CPR Part 35 SJE report; participation in joint statement process as required.

SJE Duty to the Court

The Single Joint Expert's primary duty is to the court, not to either instructing party. Instructions from both sides are summarised in the report; areas of agreement and disagreement are addressed with transparent reasoning.

SJE appointments in negligence quantum are increasingly used where proportionality requires a single financial expert rather than competing party experts.

CPR Part 35 and the SJE Protocol

SJE reports must comply with CPR Part 35 and Practice Direction 35, including the expert's statement of truth and confirmation of understanding of the duty to the court. The SJE Protocol sets expectations for joint instruction, access to documents, and joint statement procedures following exchange of reports.

CPR Part 35 Compliance

SJE reports comply with CPR Part 35, Practice Direction 35, and the SJE Protocol. The expert's duty to the court is stated expressly; instructions from both parties are summarised.

Under CPR Part 35 and Practice Direction 35, the expert's duty is to the court. Reports must state qualifications, instructions, facts, assumptions, methodology, opinion, conclusions, and contain a statement of truth. Where proceedings are in the family court, FPR Part 25 applies to expert evidence.

What must a CPR Part 35 expert report contain?
Under CPR Part 35 and Practice Direction 35, the report must be addressed to the court, state qualifications and instructions, set out facts and assumptions, give reasoned opinion, summarise conclusions, confirm the duty to the court, and include a statement of truth.
