233. In the case of joint expert evidence, the parties determine together what parameters must be covered, what expert is to be appointed, what fee is to be paid and how it is to be paid. If the parties fail to agree on any of those points, the matter is decided by the court.
A joint expert can require that the expert fee and disbursements be deposited at the court office before submission of the report. If such a deposit has not been required, the joint expert has a right of action against all the parties to the proceeding, who are solidarily liable for the amount due.
