French term (edited): un inventaire contradictoire

or mutually agreed / cross-checked / joint inventory


[un inventaire] contradictoire = an "uncontested" inventory, as all interested parties had the opportunity to object, and presumably didn't object (to the finally agreed version of the inventory).


I would understand here "un inventaire contradictoire" as "all the interested parties had the opportunity to check the accuracy of the inventory", by analogy with

− DR(oit). [En parlant d'un procès, d'une enquête] Où les parties antagonistes ont pu s'exprimer. Anton. par défaut :
4. Le tribunal d'Angoulême, ému par la belle plaidoirie de Cachan, rendit un jugement contradictoire entre toutes les parties, qui donna la propriété des meubles meublants seulement à Madame Séchard, repoussa les prétentions de Séchard père et le condamna net à payer quatre cent trente-quatre francs soixante-cinq centimes de frais. Balzac, Les Illusions perdues,1843, p. 611.

In practical terms it would mean that this inventory is "uncontested" - as all those who could raise any objection had the opportunity to do so, and presumably did not.

IOW, however it may seem contradictory to the common meaning of "contradictoire", HERE "contradictoire" would in fact mean that there is no contradiction between what parties involved have to say about this inventory.
