Child support from siblings and grandparents in Peru: when you can request it

Why does support obligation extend to siblings and grandparents?

In Peru, the duty to provide financial support (alimentos) is not limited to the parent-child relationship. The Civil Code recognizes a broader duty of family economic solidarity: spouses, ascendants and descendants, and siblings owe each other support reciprocally under certain circumstances. This means that when a child’s mother or father cannot cover the support payment — because they have no income, have died, are missing, or cannot be located — the law allows the claim to be redirected to other close relatives, such as grandparents or, as a last resort, adult siblings with financial means.

This page complements the general guide on child and family support in Peru, which explains the process when the defendant is a parent. Here we focus on the less-known scenario: what happens when the primary obligor cannot pay and the claim must go to another relative.

The order of obligors: not automatic, and different from what people usually assume

Peruvian law does not let you freely choose who to sue, and the order depends on who the claim is for. When the person who needs support is a child or adolescent and the parents are absent or their whereabouts are unknown, Article 93 of the Código de los Niños y Adolescentes (Ley N° 27337) sets this order:

1. Adult siblings.
2. Grandparents.
3. Collateral relatives up to the third degree.
4. Other persons responsible for the child or adolescent.

This means that, for a minor’s claim, the law calls on adult siblings first and grandparents second — the reverse of what is usually assumed. This obligation is subsidiary either way: it only arises when the parents are absent or their whereabouts are unknown, not simply because they “don’t want to pay” or fell behind once.

(This Article 93 order is different from the Civil Code’s general order — Articles 474 and 475 — which governs support obligations between adults, for example between spouses or between adult siblings, and which does put ascendants before siblings. That general order does not apply when the claim is for a child or adolescent.)

What you need to prove to reach a grandparent or sibling

In practice, a support claim against a grandparent or sibling requires proving two things to the judge:

• That the primary obligor cannot comply. This can be shown, for example, with a parent’s death certificate, proof they have no known assets or income, or evidence they are abroad and cannot be located or made to comply with a judgment.
• That the defendant (grandparent or sibling) has real financial capacity. The judge does not set the payment automatically; they weigh the defendant’s income, assets, and family obligations, together with the claimant’s actual needs.

Without this two-part proof, it is difficult for a court to order payment from a relative other than a parent.

The procedure is essentially the same support process

There is no “special” judicial procedure for suing grandparents or siblings: the case follows the same ordinary support (alimentos) proceeding (generally before a peace court or family court, depending on the case), only the identity of the defendant changes. You must prove the family relationship with the relevant civil registry certificates (birth certificate and, where relevant, the parents’ marriage or death certificates) and support the claimant’s actual need.

These cases often intersect with other family-law issues, such as child custody and visitation rights when the child lives with a grandparent, or inheritance matters if the obligated relative dies during the process, which connects to intestate succession in Peru and forced heirship.

What to do if you cannot afford to litigate

If the family cannot afford a private lawyer, free alternatives exist: the free legal clinics of the Ministry of Justice and Human Rights, and the guidance services of the Ministry of Women and Vulnerable Populations (MIMP), can offer advice or, depending on the case, free legal representation.

A note on this page’s evidence tier

The Civil Code article numbers cited here (474 through 483, with focus on 474, 475, and 481) correspond to the location of the Support Title widely recognized in Peruvian doctrine and case law, but they could not be confirmed by directly reading the text on an official source during this research, due to automated-access blocks on the official portals. Before making a legal decision, confirm the current text on SPIJ (Peru’s official legal information system) or consult a family lawyer.
