Short answer. Yes. Article 233 of the Family Code states that the person exercising substitute parental authority shall have the same authority over the person of the child as the parents. The substitute steps into the parent's shoes for purposes of decisions about the child's person, care, and discipline.

What the law says

The person exercising substitute parental authority shall have the same authority over the person of the child as the parents.

Substitute authority carries the same scope as parental authority

When a grandparent, sibling, or other person is designated to exercise substitute parental authority over a child, Article 233 of the Family Code makes the scope of that authority explicit: it is the same authority over the person of the child as the parents. This means the substitute may make decisions about the child's daily life, education, health, and upbringing in the same manner a parent would. The law does not create a reduced or limited form of parental authority for substitutes — the authority is equivalent.

What substitute parental authority does not permit

While the authority over the child's person is the same as a parent's, Article 233 sets a firm boundary: no corporal punishment may be inflicted on the child, and this prohibition applies with particular emphasis to school administrators, teachers, and individuals engaged in child care who exercise special parental authority. This is not a limitation only for those in an institutional setting — it reflects a general policy against physical punishment as a disciplinary tool. The substitute may guide and discipline the child by other lawful and reasonable means, but physical punishment is not among them.

Who may exercise substitute parental authority

Substitute parental authority arises when the parents are absent, incapacitated, or cannot exercise parental authority themselves. The Family Code provides an order of priority among those who may step in: grandparents come first among relatives, followed by the eldest brother or sister who is at least twenty-one years old, and then the child's actual custodian who has at least the same relationship as siblings. The person exercising substitute authority does so in the best interest of the child — it is not a right the substitute holds for their own benefit, but a responsibility assumed on behalf of the child.

Practical meaning for families in this situation

If you are a grandparent or sibling currently raising a child because the parents cannot do so, the law recognizes your authority to make the same decisions for the child that a parent would make — school enrollment, consent to medical care, day-to-day upbringing. You do not need a court order to exercise substitute authority in the ordinary case, though formal legal arrangements (such as guardianship proceedings) may be advisable if the child's parents are permanently unavailable or if you need to act in the child's interest in legal matters. A lawyer can help you assess whether the informal arrangement is legally sufficient for your specific circumstances.
