Instruction & issues
The Letter of Instruction, questions for the expert and the procedural context are reviewed so the required evidence is clear.
Selective expert witness instructions
Formal expert evidence when the court process genuinely requires it
SurveyAll considers selected building surveying expert witness instructions after the formal issues, competence, conflicts, legal instructions and court requirements have been reviewed.
Duty to the court
Formal instructions
Scope & competence review
A separate professional role
Independent. Objective. Procedurally defined.
- Not an advocacy report for the paying party
- Issues must fall within the expert's competence
- Material instructions and evidence must be clear
- Formal report requirements apply where Part 35 governs
Different from ordinary client advice
An expert witness assists the court, not the side paying the fee
Under CPR Part 35, the expert's overriding duty is to help the court on matters within the expert's expertise. That duty overrides obligations to the person giving instructions or paying the expert.
For that reason, expert witness work is not treated as an upgraded defect survey. The precise expert questions, legal framework, documents, timetable and any Court Directions need to be understood before SurveyAll confirms whether the instruction is appropriate.
Before appointment
How a potential expert witness instruction is reviewed
Formal acceptance comes after the instruction has been checked, not simply after an enquiry is received.
Competence & conflicts
SurveyAll considers whether the issues fall within the surveyor's expertise and whether any conflict prevents acceptance.
Evidence & access
Relevant pleadings, schedules, photographs, previous reports, repair records and access requirements are identified before the scope is finalised.
Scope, timetable & fee
The inspection, report, further questions and any later expert activity are scoped against the court timetable and the work reasonably required.
Potential areas of instruction
Selected residential building surveying matters may include:
- building defects and visible workmanship issues;
- condition and repair evidence;
- damp, water ingress and building pathology within competence;
- structural movement observations where the issues fall within building surveying expertise;
- residential valuation matters where appropriately instructed; and
- other defined residential property issues after scope review.
Professional boundaries
Expert evidence must remain within the instructed issues and the expert's expertise
Defined issues
The report addresses the questions the expert has actually been instructed and permitted to address.
Objective opinion
Material facts that support or detract from an opinion must be considered rather than advocacy adopted.
Limits stated
Questions outside expertise or conclusions that cannot be reached from the available evidence are identified.
Formal compliance
Where Part 35 applies, the report is prepared to the applicable procedural requirements and declarations.
Often a simpler report is enough
Do you actually need an expert witness?
Many property concerns first need clear factual evidence, not court evidence. Using the proportionate route avoids unnecessary formality and cost.
Independent evidence route
- building work assessment;
- condition and evidence schedule;
- property evidence report;
- focused defect investigation;
- appropriate where the immediate need is technical clarity or a factual record.
Expert witness route
- formal litigation or proceedings;
- expert questions defined by legal instruction;
- court duty and procedural requirements;
- possible single joint expert appointment;
- accepted only after instruction and competence review.
Important: SurveyAll does not accept a private client's request for a "court report" as sufficient by itself to create a CPR Part 35 appointment. The legal instruction and required expert issues must first be reviewed.
Common questions
Expert witness instructions
Do you accept every expert witness instruction?
No. Expert witness work is accepted selectively. The subject matter, formal issues, competence, conflicts, timetable and procedural requirements must be reviewed before an appointment is confirmed.
Should the solicitor send a Letter of Instruction?
Yes. For a potential CPR Part 35 instruction, SurveyAll expects the formal issues and required expert evidence to be defined through the legal instruction. Court Directions and relevant pleadings, schedules, reports or evidence should also be provided where applicable.
What is different about a CPR Part 35 report?
An expert instructed for proceedings has an overriding duty to help the court on matters within the expert's expertise. The report has formal content and declaration requirements and is not simply a stronger version of an ordinary client report.
Can a homeowner order a Part 35 report directly?
SurveyAll generally requires formal legal instructions for CPR Part 35 work and does not treat a normal homeowner dispute enquiry as an expert witness appointment. An independent evidence report may be the more appropriate starting point in many cases.
Can you act outside your expertise?
No. An expert should only give opinions within their expertise and should identify when a matter requires another discipline or when the available evidence is insufficient for a definite opinion.
