Why You Might Need an Expert Witness Report — A Guide from DAW Surveyors
When a property dispute escalates to the point of legal action, or a professional opinion is needed in court, one crucial tool can make all the difference: the Expert Witness report. At DAW Surveyors, we regularly provide impartial, detailed, and court-compliant Expert Witness reports to help clients navigate complex property-related issues.
Whether you're involved in a boundary dispute, building defect claim, professional negligence case, or matrimonial separation, an Expert Witness can provide the authoritative voice needed to support your position or clarify the facts for a judge.
In this blog post, we’ll explore what an Expert Witness is, when you might need one, what a typical Expert Witness report includes, and why choosing a qualified RICS surveyor is essential for your case.
What Is an Expert Witness?
An Expert Witness is an independent professional with specialist knowledge or experience who is appointed to give an impartial opinion to the court or tribunal on matters within their expertise. In the property world, this typically involves building surveyors or valuers who assess physical conditions, defects, valuations, or the conduct of other professionals.
Crucially, the Expert Witness’s primary duty is to the court, not to the client. This duty to be objective, even if it doesn’t support the appointing party’s case, helps ensure that the legal process is fair and evidence-based.
Why Might You Need an Expert Witness Report?
There are a range of scenarios where instructing an Expert Witness becomes essential. Below are some of the most common reasons property owners, landlords, tenants, and professionals seek out this service:
1. Boundary Disputes
Property boundaries are among the most contested and emotional disputes between neighbours. An Expert Witness can interpret title plans, historical records, and physical evidence to provide a reasoned and impartial opinion to support resolution.
2. Construction Defects
If a building has been poorly constructed, or if defects have arisen due to poor workmanship or materials, an Expert Witness report can assess the extent of the damage, likely causes, and cost of remedial works. These reports are vital in negligence claims or disputes with contractors.
3. Party Wall Matters
Disagreements over party wall issues—such as structural work, encroachments, or damage caused during construction—often benefit from an Expert Witness to interpret the Party Wall Act 1996 and provide technical clarity.
4. Valuation Disputes
Disagreements over the value of property, particularly in inheritance, divorce, or tax matters, may require a surveyor acting as an Expert Witness to determine accurate market value or rental value.
5. Professional Negligence
If another surveyor, architect, or builder has failed in their professional duty—perhaps through a poor survey or defective design—an Expert Witness can review the work and provide an opinion on whether it met professional standards.
6. Matrimonial or Probate Proceedings
During divorce or inheritance cases, Expert Witness valuations may be required to establish fair division of assets or confirm financial contributions.
What Does an Expert Witness Report Include?
A professionally prepared Expert Witness report must follow strict legal protocols, such as those outlined by the Civil Procedure Rules (CPR) Part 35 in England and Wales. At DAW Surveyors, we ensure all our reports meet the highest standards. A typical report includes:
Executive Summary – A brief overview of the issues and conclusions.
Instructions and Role – Who instructed the Expert Witness, and the scope of their appointment.
Compliance Statement – Confirming impartiality and adherence to CPR Part 35 or equivalent.
Background Information – Relevant property history, documents reviewed, and site visits.
Facts and Assumptions – A clear distinction between established facts and expert assumptions.
Analysis and Opinion – A detailed technical assessment, explanation of methodology, and expert conclusions.
Appendices – Supporting evidence, site photos, plans, and references to standards or legislation.
How Is an Expert Witness Appointed?
An Expert Witness can be appointed in one of two ways:
1. Single Joint Expert
In some cases, both parties agree to instruct one Expert Witness to act jointly. This can reduce costs and prevent prolonged legal arguments over conflicting expert opinions.
2. Party-Appointed Expert
Each party may appoint their own expert, particularly in more adversarial disputes. In these cases, the court may instruct both experts to produce a joint statement outlining where they agree or disagree.
Regardless of how they are appointed, the overriding duty of an Expert Witness remains the same: to assist the court objectively.
What to Look for in an Expert Witness
Choosing the right Expert Witness is crucial to the success of your case. Here are some key qualities to look for:
Relevant Qualifications – Look for RICS chartered surveyors or valuers with experience in Expert Witness work.
Understanding of CPR 35 – The report must comply with legal protocols to be admissible in court.
Impartiality and Clarity – The report should be objective, clearly written, and understandable to laypersons and legal professionals alike.
At DAW Surveyors, we are proud to offer RICS-registered surveyors with experience in providing Expert Witness reports across residential, commercial, and land-related disputes.
