Visi vertimai

Buenos dias, el texto que quisiera traducir es un trozo de un contracto de arrendamiento financiero (en francès, un contrat de crédit-bail), entonces es vocabulario juridico.
Me parecia que "a expensas de" significaba "aux dépens de", mais alors je ne comprends plus.

Je remercie ceux qui auront la gentillesse de m'apporter leur traduction.
