The Role of the HKA Expert

Expert witness

HKA’s expert witnesses bridge the legal-technical divide, and they draw on first-hand experience gained in many specialisms, and sectors – from construction and engineering, energy and natural resources, infrastructure and real estate, to tourism, life sciences, media and technology, and financial and professional services.

As an independent firm with a global reach specialising in claims and disputes, we can recommend experts – who are carefully screened for potential conflicts – to testify in any case.

The authority of an expert witness stems from clarity as well as knowledge. Our experts are highly skilled in presenting evidence and drafting draft well-structured reports that cut through complexity to the heart of the matter.

Expert advisory

When instructed as expert advisers, our consultants apply real-world insights to inform and guide their investigations and analysis.

The stronger the research and the structure of a claim or defence, the greater your likelihood of successful settlement and, ultimately, lower costs. HKA’s dedicated digital and graphic resources also help speed up the process and communicate our findings clearly.

As resolute, trustworthy advisers, we also minimise the risk of a client proceeding where a claim or defence will not stand up to detailed scrutiny.

Expert determination

HKA experts are highly regarded for their work in arbitration and adjudication, and alternative pathways to dispute resolution.

Acknowledged experts in their fields, they are equipped to investigate the facts and interpret the law. Their standing and impartiality inspire the confidence of all parties to a dispute.

HKA experts have determined disputes across a wide range of industry sectors, from construction and manufacturing to processes and technology.
