Short answer. Yes, but only as a substitute, and only in a specific order. Grandparents step in as guardians when both parents have died, are absent, or are unfit — they do not compete with a fit, available parent for custody, and among several grandparents, the court designates which one exercises that authority.

What the law says

In case of death, absence or unsuitability of the parents, substitute parental authority shall be exercised by the surviving grandparent.

What the law says

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.

Substitute, not concurrent, parental authority

Article 214 of the Family Code answers this narrowly: substitute parental authority passes to the surviving grandparent only in case of death, absence, or unsuitability of the parents. That word, substitute, is the key to the whole rule. A grandparent does not compete with a fit, available parent for custody of a grandchild; the grandparent's authority exists only to fill a gap left when neither parent can exercise parental authority at all. If more than one grandparent survives — both grandmothers, say, or grandparents on both sides of the family — the law does not automatically pick one; the court designates which grandparent will exercise the authority, weighing the same considerations used to choose between parents.

The order of preference under Article 216

Article 216 sets out where grandparents fit in a longer chain of substitute caregivers. In default of the parents or a judicially appointed guardian, the order runs: first, the surviving grandparent, as Article 214 provides; second, the oldest sibling over twenty-one, unless unfit or disqualified; and third, the child's actual custodian, again over twenty-one and not unfit or disqualified. The same order controls when a court needs to appoint a judicial guardian over the child's property, not just over the child personally. A grandparent's priority is real, but it is a priority within a list, not an automatic entitlement that overrides everyone else's claim.

Substitute authority is an order, not a menu

The law sets an order, and the order is not a list of options a court may pick from. Substitute parental authority passes first to the surviving grandparent, then to the oldest brother or sister over twenty-one who is qualified, then to the child's actual custodian over twenty-one who is qualified — and in choosing, the court is directed to take the child's welfare into account. This matters most when a biological parent appears and asks for custody on the strength of parentage alone. Parentage establishes who a parent is. It does not by itself displace an order the law has already set, nor does it answer the question a court actually has to decide.

The limits of a grandparent's role while a parent is still around

Substitute authority is exactly that — a substitute. It arises in case of death, absence or unsuitability of the parents, which means it does not arise while a fit parent is present and exercising authority. A parent who asks grandparents to help raise a child, or who leaves the child in their day-to-day care, has delegated care; they have not transferred parental authority, and the grandparents' position stays derivative of the parent's. That distinction decides a surprising number of disputes. Physical custody of a child, however long-standing and however loving, is not the same legal thing as authority over that child.
