Article 2253Order of Preference of Credits

The Civil Code of 1889 and other previous

laws shall govern rights originating, under said laws, from

acts done or events which took place under their regime,

even though this Code may regulate them in a different

manner, or may not recognize them. But if a right should

be declared for the first time in this Code, it shall be

effective at once, even though the act or event which

gives rise thereto may have been done or may have

occurred under prior legislation, provided said new right

does not prejudice or impair any vested or acquired right,

of the same origin. (Rule 1)
