The fee for an act depends on its nature, the analyses needed and the declarant's status. This page gives the indicative scale; the final quote is drawn up at admissibility.

Amounts are expressed in euros, excluding taxes. They cover the expert's time, the committee's processing, entry in the Registry and issue. Laboratory analyses are invoiced in addition, at the partner laboratory's actual cost.

No act is invoiced according to the value of the work or the outcome of the opinion: the fee is the same whether the certificate is issued or refused.

Refunds and cancellations

Before the expert is appointed, the deposit is refunded at 70%. After appointment, the costs incurred (expert, laboratory, transport) are retained.

A refused file does not give rise to a refund: the fee pays for the examination, not the result. A re-examination requested within 30 days is invoiced at 30% of the initial fee.
