EXONERATUR, practice. A short note entered on a bail piece, that the bail is exonerated or discharged in consequence of having fulfilled the condition of his obligation, made by order of the court or of a judge upon a proper cause being shown. 2. A surrender is the most usual cause; but an exoneratur may be entered in other cases, as in case of death of the defendant, or his bankruptcy. 1 Arch. Pr. 280, 281, 282; Tidd's Pr. 240.
