Reserva troncal, under Article 891 of the Civil Code, is a special rule that reserves certain property for relatives of the same family line. It applies when an ascendant inherits, by operation of law, property that a descendant had earlier acquired by gratuitous title (donation or inheritance) from another ascendant or a brother or sister. That ascendant, the reservor, must reserve the property for relatives within the third degree who belong to the line from which the property came, the reservees. Its purpose is to prevent property from passing out of the family line from which it originated.
Reserva troncal is one of the more intricate rules in Philippine succession law, but its purpose is simple and deeply Filipino: to keep property within the family line it came from, so that assets do not drift to the other side of the family by an accident of deaths.
The Purpose
Reserva troncal (found in Article 891 of the Civil Code) exists to reserve property for relatives of the line from which it originated. Without it, property that entered a family from one branch could, through a chain of inheritances, end up entirely with the other branch — which the law considers unfair to the originating line. Reserva troncal prevents this by imposing a reservation.
When It Applies: The Four Elements
Reserva troncal is triggered only when a specific chain of facts exists:
- A descendant acquired property by gratuitous title (donation or inheritance) from an ascendant, or from a brother or sister (the origin);
- That descendant (the propositus) dies without issue;
- The property passes by operation of law (intestate succession) to another ascendant (the reservor / reservista); and
- That ascendant belongs to a different line from the origin.
When these concur, the property becomes reservable in the hands of the reservor.
The Key Players
- The origin (originator) — the ascendant, brother, or sister from whom the property first came by gratuitous title;
- The propositus — the descendant who received it and later died without issue;
- The reservor (reservista) — the other-line ascendant who inherits it by operation of law, and who must reserve it; and
- The reservees (reservatarios) — the relatives within the third degree of the propositus who belong to the line from which the property came, for whose benefit it is reserved.
The Effect of the Reservation
The reservor owns the reservable property, but that ownership is subject to a resolutory condition: upon the reservor’s death, the property must pass to the reservees (the third-degree relatives from the originating line) who survive. The reservor may use the property during their lifetime, but generally cannot dispose of it in a way that defeats the reservation, and there are steps to annotate the reservable character on the title to protect the reservees. If no reservee survives the reservor, the reservation is extinguished and the property remains with the reservor’s own heirs.
Why It Matters in Practice
Reserva troncal surfaces in real family estates — a grandchild who inherited land from a grandparent dies young and childless, the land goes to the surviving grandparent on the other side, and the relatives of the originating grandparent later claim it as reservees. Because the rule is technical and easy to overlook, reservable property is sometimes sold or distributed as if free, creating disputes when reservees assert their rights. Identifying a reserva troncal situation early — and annotating it — prevents costly conflicts.
Practical Advice
- If an estate involves property a young, childless descendant inherited from a grandparent or sibling that then passed to an ascendant on the other line, consider whether reserva troncal applies.
- Where it does, the property should be annotated as reservable to protect the third-degree relatives of the originating line.
- Because the analysis is technical, get advice before selling or distributing potentially reservable property.
Frequently Asked Questions
What is reserva troncal? A special rule under Article 891 that reserves property for relatives of the same family line. It applies when an ascendant inherits, by operation of law, property a descendant earlier got by gratuitous title from another ascendant or a sibling, requiring that ascendant to reserve it for third-degree relatives of the originating line.
Who are the reservees? The relatives within the third degree of the propositus who belong to the line from which the property originally came. They are entitled to the reserved property upon the reservor's death if they survive.
Can the reservor sell the reservable property? The reservor owns it but subject to the reservation, and generally cannot dispose of it in a way that defeats the reservees' rights. The reservable character should be annotated on the title to protect them.
What if no reservee survives? If no reservee survives the reservor, the reservation is extinguished and the property remains with the reservor's own heirs.
