Expert determination

An expert determination is a form of alternative dispute resolution whereby a third-party subject-matter expert is appointed to determine how the issues in dispute should be resolved.

The use of expert determination to resolve disputes is typically more timely, less costly and more private than litigation or arbitration. In addition, the expert’s determination is often final and binding (in the absence of fraud or error) depending upon the contractual terms agreed with the parties.

Acting as Expert Determiner

Our experts have significant experience acting as Expert Determiners - building on their experience acting as party-appointed, single joint experts or advisors in litigation and national and international arbitration.

Expert determinations can be used to determine disputes over matters such as valuations or accounting treatment or disputes relating to mergers and acquisitions (“M&A”) (such as disputes involving completion accounts or earnouts).

Expert determination support

Where we are not acting as Expert Determiner, we can support parties through the expert determination process; providing our instructing party with appropriate guidance and assisting with the submission process to ensure the Expert Determiner is provided with a cohesive and well-documented position.
