French term (edited): relever d’office tous les éléments

d’office = there is no need for the judge to wait that anyone asks him to do so, it can [even have to] to do it on its own initiative as its his duty to do so.

relever = here not only to spot the relevant information, but also to take it into account, to act on it

[Il appartient en effet au juge d’examiner si les conditions légales de l’action exercée by le demandeur sont remplies.] *** Il peut relever d’office tous les éléments qui le déterminent à penser que *** [l’une des conditions d’application de la règle invoquée fait défaut.]

this is about the stage where the judge has to decide whether to take the case at all or refuse to even look at the substance of the claim, it's about "décider de la recevabilité de la plainte" - nothing more - these "éléments" here are various formal requirements that must be satisfied for a plaintiff to be able to start a legal action, not about any evidence/proofs related to the case itself.

conditions légales = HERE: is the case within the competence of the tribunal (territorial competence, type of cases), has the plaintiff legal capacity (not a minor, of sound mind, properly authorised to act on behalf of an entity etc) has the plaintiff any real/legitimate "cause for action" and similar.

also Proc. Civ. = procédure civile, so it's a dispute about money, not a criminal case.

A complaint generally has the following structural elements:[2]

Caption and Heading - lists name, address and telephone number of the filing attorney or self-representing litigant at the top of the complaint. The case caption usually also indicates the court in which the case originates, names of the parties and a brief description of the document.

Jurisdiction and venue - this section describes why the case should be heard in the selected court rather than some other court or forum.

Parties - identifies plaintiffs and defendants.

Definitions - optional section which defines some terms used throughout the document. The main purpose of a definition is to achieve clarity without needless repetition.[5]

Statement of facts - lists facts that brought the case to the court.

Cause of Action - a numbered list of legal allegations (called "counts"), with specific details about application of the governing law to each count. In this section the plaintiff usually cites existing Law, previous decisions of the court where the case is being processed, decisions of the higher appellate courts, and cases from other courts, - as an analogy to resolve similar questions of law.

Injury - plaintiff explains to the judge how the actions of the defendant(s) harmed his rights.

Demand for relief - describes the relief that plaintiff is seeking as a result of the lawsuit. The relief can include a request for declaratory judgment, a request for injunctive relief (non-monetary relief), compensatory and actual damages (such as monetary relief), punitive damages (non-compensatory), and other relief.
