Single Joint Expert
Definition
An expert appointed jointly by the parties and the court, rather than by one side. Common in lower-value UK civil claims under the CPR. The single joint expert owes a duty to both parties and the court, which makes independence even more visible but can create difficulties in adversarial proceedings.

Common questions
How does a single joint expert differ from a party-appointed expert?+
A party-appointed expert is instructed and paid by one side and traditionally seen as aligned with that side's case, while a single joint expert is instructed by both parties together and owes an equal duty of independence to each side and to the court.
What difficulty can arise from using a single joint expert in fraud litigation?+
Because only one expert opinion is produced, a party who disagrees has limited scope to obtain a competing analysis without court permission, which can be contentious in complex fraud cases where methodology or interpretation of financial evidence is genuinely disputed.
