Overview

The private expert registered on a list of a court of appeal or the Court of Cassation is a highly qualified professional in a technical field (construction, IT, automotive, medicine, accounting, etc.). They can be consulted directly by an individual, a company, a lawyer, or an insurance company, independently of any appointment by a court.

Being included on an official court list constitutes formal recognition of the expert’s professional qualifications by the judicial authority, but when acting independently, the expert is not acting as a court-appointed expert and is bound by a contract with the client.

The expert’s role is to analyse technical evidence, identify defects, determine their causes, assess losses and provide a reasoned opinion that can facilitate an amicable settlement or prepare for court proceedings.
