Expert Determination

Expert determination can occur at any time in a dispute and often occurs before or instead of litigation. Expert determination can offer the benefits of cost savings and shortening the length of hearings or trials. It is often provided for in contracts.

Expert determiners may be selected because of their legal expertise in a particular area of law that is relevant to the dispute at hand. They will be able to use their legal knowledge to resolve the issues involved in the dispute. Expert determiners may decide all issues between the parties, or a specific issue chosen by the parties. The decision may be binding or non-binding.

A number of our barristers accept appointments to act as expert
determiners either as the sole determiner or as a member
of a panel.
