Examples of circumstances giving rise to a natural obligation are:
(1) When a civil obligation has been extinguished by prescription or discharged in bankruptcy.
(2) When an obligation has been incurred by a person who, although endowed with discernment, lacks legal capacity.
(3) When the universal successors are not bound by a civil obligation to execute the donations and other dispositions made by a deceased person that are null for want of form.
