Short answer. Support is not only a parent's duty. The Family Code obliges spouses, descendants, ascendants and siblings to support one another, so grandparents, adult children and even brothers and sisters can be legally bound where the closer relatives cannot provide it.

What the law says

The spouse; (2) The descendants in the nearest degree; (3) The ascendants in the nearest degree; and (4) The brothers and sisters.

Four categories of people, not one

People asking about support usually mean a father and a child, but the Family Code casts the net considerably wider. Article 199 names those who may be obliged: The spouse, the descendants in the nearest degree, the ascendants in the nearest degree, and the brothers and sisters. So an adult child can owe support to a parent, a grandparent to a grandchild, and a sibling to a sibling. The obligation is reciprocal within the family relationships the Code recognises, and it does not depend on anyone having agreed to it. Nor does it depend on the parties being on speaking terms: estrangement between a parent and an adult child does not remove either from the list.

Siblings are included, with one qualification

Article 196 confirms that the duty between brothers and sisters holds even where they are not legitimately related, whether of the full or half-blood. It carries a limit the other categories do not: a sibling of age whose need for support is due to a cause imputable to that person's own fault or negligence cannot claim it. The exception is narrow and, notably, applies only to siblings who are already of age — the Code does not extend the same defence against a claim by a minor brother or sister.

Being on the list is not the same as being first in line

Article 199 does more than name the obliged persons — it ranks them, and the liability devolves in the stated order. A grandparent is therefore not answerable while a parent can provide, and a sibling is not reached while ascendants or descendants can. What the list gives a family in difficulty is a further place to look when the primary obligor genuinely cannot pay, rather than a menu of people to choose between. Whether a particular relative can be required to contribute depends on that ordering and on each party's actual means.
