Disputes are to be avoided if possible, but regrettably, there are occasions when parties find themselves considering litigation as the only way forward to resolve a dispute. We support parties that are contemplating or are already involved in litigation via expert witness appointments.

Expert Witness

Supporting those contemplating or who are already involved in litigation. With both professional and technical experience, we are able to provide accurate, non-partisan opinions when producing and presenting factual evidence to tribunals.

Building defects can arise due to poorly built new works, inappropriate alterations undertaken on a property or defects that may have been built into the original structure at the time of construction. Simple examples include defective replacement window installation and defective workmanship or construction. The contested value of any work carried out can also result in a dispute between the parties.

Professional appointments can be made by either or both parties. Should individual parties instruct their own Expert Witnesses, both experts will usually meet to consider agreeing common ground and those matters remaining disputed to be the focal point of the individual reports. It is important to note that both experts are legally required to act impartially and present an unbiased professional opinion to the Courts in their reports. Such reports are usually required to be presented in a specific format (CPR35).

Often, the judge will instruct both parties to agree on the appointment of a single expert witness and may specifically require a Chartered Building Engineer or Surveyor to provide an opinion to the Court on the cause of any and each defect, quality of workmanship or value of work completed. Unless specifically instructed otherwise, liability is then determined by the Judge.

As experts, we will provide professional, unbiased and impartial Expert Evidence and Expert opinion in compliance with the Royal Institution of Chartered Surveyors (RICS) Practice Statements. We understand the litigation process and are familiar with legislation, regulations and guidance applicable to the Expert Witness work, working with our client and any advisors to consider pre-action protocols, conferences, meetings, settlements and/or narrowing of issues.

Should you have a building or construction dispute relating to construction quality, building pathology, or dilapidations etc., it is recommended to discuss your requirements with us initially.
