School of professional training of the Bars of the Court of Appeal of Paris (EFB) has contacted the European Institute of Expertise and Expert (EEEI) to set up various information and training actions for future lawyers and for the continuing training of practising lawyers.

Among these actions, is the production of a PRACTICAL GUIDE TO THE EXPERTISE OF JUSTICE for lawyers, but also for experts, to be part of the “Bibliothèque de l’avocat” collection.

EEEI has entrusted to Jacques Lauvin, a justice expert, and to Jean-Christophe Caron, President of the Bar, with the production of this guide.

They brought together various authors for the drafting of the various chapters, legal experts, lawyers and magistrates, some thirty people at present and forty-five in the long term.

The general summary has been fixed, the work schedule has been established, each author has received his or her roadmap and the drafting work has already begun. The objective is to present the book in about 1 year.

The particularity of this practical guide is, according to the wishes of Jacques Lauvin and Jean-Christophe Caron, that it is written “with two hands”.

Thus, on each theme, the expert and the lawyer will express themselves in parallel, thus allowing the reader to know and understand the constraints, obligations, possibilities, aims and methods of each actor’s actions.

Indeed, if the legal expertise is conducted by the expert, it is the lawyer who will have initiated it for his client.

The legal expert and the lawyer do not oppose each other, even if their opinions sometimes differ. Their functions are different: the expert fulfils the mission entrusted to him by the judge, the lawyer is at the service of the interests of his client.

They both work under the same rules, those of the Civil Code, the Code of Civil Procedure, the Code of Criminal Procedure, the Penal Code or the Code of Administrative Justice (CJA) as the case may be.

A successful expertise is one that results in a transaction on a sound basis that has been identified during the expertise, or if this is not possible, a judgment that will be accepted by the Parties, and should be enforceable without appeal or cassation.

To achieve this result, it is necessary for the expert and the lawyer to act in a precise knowledge of each other’s roles, and it is the purpose of this practical guide to present their roles and working methods, it will include many frameworks, models, examples, and reference texts from the CPC, CJA, or case law. A chapter will be reserved for cross-border expertise.
