FAQ — Part 35 Compliant Expert Witness Reports
What does “Part 35 compliant” mean?
It refers to Civil Procedure Rules (CPR) Part 35, which govern how expert evidence is prepared and presented in court. A Part 35 compliant report follows strict rules on impartiality, transparency, and independence, and includes a signed declaration confirming the expert’s duty is to the court — not the instructing party.
Who can instruct a Part 35 expert?
Typically, solicitors, insurers, local authorities, or private individuals involved in litigation or formal dispute resolution. Before accepting instruction, we confirm the expert’s competence, scope, and potential conflicts of interest.
What types of cases require expert witness reports?
We support cases involving property damage, vegetation-related disputes, invasive species, planning enforcement, or land valuation issues where specialist technical interpretation is required.
How independent are ProHort experts?
Fully independent. Our experts are bound by CPR Part 35 to always remain impartial. Reports are written solely by ProHort specialists and reviewed internally under our Quality Assurance and peer review protocols to ensure factual accuracy and neutrality.
What information will you need before starting?
We request a summary of the dispute, any previous reports or correspondence, photographs, and relevant drawings or documents. This allows us to define the instruction precisely and avoid duplication of work.
How long does the process take?
Reports are typically completed within 10 working days from inspection or confirmation of instruction. Expedited cases can often be delivered sooner where evidence is complete and access is immediate.
Will the expert need to visit the site?
In most cases, yes. Site inspection ensures the evidence is first-hand and defensible. Occasionally, a desktop review may be suitable if all verified data is already available.
Do you attend court if required?
Yes. Our experts can provide written or oral testimony as part of formal proceedings, mediation, or arbitration. Attendance is scheduled in advance to maintain case continuity.
Are ProHort reports accepted by insurers and courts?
Yes. Our format and methodology meet UK court and insurer standards, and our experts regularly prepare evidence accepted in both civil and planning proceedings.
Can the same expert later act as an adviser?
No. Once appointed as an independent expert witness under Part 35, we cannot act as an advocate or partisan adviser in the same case. This separation preserves integrity and admissibility.
Will I know costs before instruction?
Always. A written quotation and scope confirmation are issued before work begins, detailing likely costs for inspection, reporting, and any future court attendance.
