HKA, a leading global consultancy in risk mitigation, dispute resolution, expert witness, and litigation support services, is expanding its presence in the Benelux region with a new service line and additional office in Amsterdam, the Netherlands.

The firm has had a footprint in the region for over 40 years, working for clients to deliver dispute resolution services, including construction claims consulting, expert advisory, and expert witness support. The launch of a Forensic Accounting and Commercial Damages (FACD) practice in a second office in the Netherlands is a significant development for the business and will mean HKA is providing Financial Dispute consulting-services to complement its existing Construction Claims and Expert (CCE) services which have been offered in the market since April 2024. These two compact teams will represent a unique multi-disciplinary approach not currently offered in the Benelux region, thereby offering a breadth of combined capabilities when resolving complex disputes.  

Leading HKA’s expansion in the Netherlands is Partner Mark Castell, together with newly appointed Partner Tjeerd Krol. The Dispute Consulting-team will be supported by two additional new appointees, Director Tony Mauritz and Associate Tygo Fijn. Additionally, Kadir Firat Varol will enhance the CCE team in the Netherlands.

“The new service line offering signifies the enhancement and diversification of HKA’s presence in the Dutch market, thereby uniquely positioning the firm to offer services from both our Forensic Accounting and Commercial Damages practice, as well as our Construction Claims Expert practice. I believe that this is a unique offering amongst our peers, and the value of this proposition is a very welcome development for our broad client base.”

Mark Castell, Partner

“Given the increasing demand for Forensic Accounting and Commercial Damages expertise in the Netherlands, coupled with the opportunity to collaborate effectively with experts from other service lines, I am eager to offer our clients comprehensive solutions. These will encompass services such as commercial damage assessments, economic analysis, and investigative support.”
