Short answer. When parents are absent and no judicial guardian has been appointed, Family Code Article 216 gives substitute parental authority first to the surviving grandparent, then to the oldest sibling over 21, and finally to the child's actual custodian over 21 — in that order.

What the law says

In default of parents or a judicially appointed guardian, the following person shall exercise substitute parental authority over the child in the order indicated: (1) The surviving grandparent, as provided in Art. 214; (2) The oldest brother or sister, over twenty-one years of age, unless unfit or disqualified; and (3) The child's actual custodian, over twenty-one years of age, unless unfit or disqualified.

The three-tier order of substitute authority

Article 216 sets out a clear hierarchy. When neither parent is present and no court has appointed a guardian, authority falls first to the surviving grandparent. If there are no grandparents able to exercise authority, it passes to the oldest brother or sister who is at least 21 years old. If no such sibling exists or is available, the authority goes to the child's actual custodian — the person currently taking care of the child day to day — provided that person is over 21. The order is fixed; no one lower in the list can jump ahead while someone higher is available and qualified.

Age and fitness requirements for siblings and custodians

The article imposes conditions on the second and third tiers that do not appear explicitly for grandparents. The oldest sibling must be over twenty-one years of age, and the same applies to the actual custodian. More importantly, both can be passed over if they are unfit or disqualified. Unfitness is a factual question — it can arise from abuse, neglect, criminal history, substance dependence, or any other circumstance that makes the person unsuitable to exercise authority over a child. Disqualification can be the result of a legal proceeding or order that formally bars them from the role.

What 'substitute parental authority' actually covers

Substitute parental authority under Article 216 is not a watered-down version of ordinary parental authority. The substitute exercises the same rights and duties a parent would — decisions about the child's education, health, religious upbringing, and day-to-day welfare. The same person also stands in the parent's position for liability purposes: a substitute exercising parental authority can be held responsible for the child's acts that cause damage, in the same way a parent would be. This is not merely a custodial arrangement; it is a full transfer of the parenting role while it is needed.

When a judicial guardian should be appointed instead

Article 216 applies in the absence of a judicially appointed guardian — but sometimes the proper step is to petition the court to appoint one, rather than rely on the automatic order of priority. This is particularly true when the child has significant property. Article 216 itself notes that the same order of preference applies when a judicial guardian over the child's property becomes necessary. For a child who inherits real estate, receives insurance proceeds, or has other assets, a formal guardianship proceeding provides legal protection and accountability that informal substitute authority does not. If you are looking after a child in this situation, consulting a lawyer about whether a guardianship petition is needed is a prudent step.
