Expert Witness Architects
Sussex, Kent, Surrey and London

When parties in a construction contract fail to agree, arbitration, litigation and adjudication are unavoidable. In such an event, it is important to have an expert opinion to defend or support a claim from either party. 

The primary duty of the expert is to provide evidence based on facts. Thus, expert witnesses are either consulting experts or testifying experts; either way, both will provide valuable input in a dispute case. The feedback provided can allow a solicitor or a prosecutor to prepare their case in court and help the judge come to a decision.

Testifying expert

Generally, a testifying expert witness will provide the jury or the judge the logic behind a particular situation in the dispute. 

We specialise in providing evidence to show situations where the defendant was negligent or where the claimant was not, or explain what a reasonable professional would have done in a similar circumstance, and the potential loss caused by a negligent act. 

Consulting expert 

Primarily, a consulting expert witness is called upon to help solve a dispute by providing private counsel in the case. They will provide insight into various elements of the case, and help either party in the dispute prepare their argument. 

In litigation cases, the expert's witness overriding duty is to assist the court within their matter of expertise. In arbitration, a similar duty of loyalty is exercised to the tribunal. 

Because an expert witnesses has an overriding duty in litigation and arbitration negotiation; we pride ourselves to provide precise and reliable advice to help solve a dispute in the most effective way. We will prepare a comprehensive report for litigation and arbitration or give oral testimony to support or defend a claim.
