Question juridique clé
Whether the signed addendum constituted a debt acknowledgment supporting provisional release under Art. 82 LP.
Solution extraite
Yes, the document was in principle a written acknowledgment of debt; at the provisional-release stage the undertaking could not be recharacterized on the available record.
Motifs extraits
A signed private document stating a clear, due monetary obligation qualifies under Art. 82 LP. At the summary, documentary stage, the court must rely on the apparent acknowledgement unless immediate liberatory proof is shown.
