What happens if a jointly liable obligor admits an obligation?
An admission of an obligation made by a jointly liable obligor shall have no effect against the other obligors. They will not be prejudiced if the obligee demands the oath from the obligor and he refuses, or if the obligor demands the oath from the obligee and he takes it. However, if the obligee demands the oath from the obligor and he takes it, the other obligors will benefit from it.
