Overview<\/strong><\/h2>\n\n\n\n

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.<\/p>\n\n\n\n

Being included on an official court list constitutes formal recognition of the expert\u2019s professional qualifications by the judicial authority<\/strong>, but when acting independently, the expert is not acting as a court-appointed expert and is bound by a contract with the client.<\/p>\n\n\n\n

The expert\u2019s 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.<\/p>\n\n\n\n
