obligation reconnue

CONT: [...] si le débiteur de l'obligation naturelle l'exécute volontairement et en connaissance de cause, il est censé exécuter une obligation reconnue par le droit positif.

CONT: Bill obligatory. An instrument in common use and too well known to be misunderstood. It is a bond without condition, sometimes called a single bill, and differs in nothing from a promissory note, but the seal which is affixed to it.
