Short answer. Ordinary guardianship rules fully apply in three situations: when the child is under substitute parental authority, when the guardian is a stranger rather than a parent, or when a parent has remarried. Outside those three cases, the regular rules on guardianship are only supplementary to the parents' automatic joint guardianship.

What the law says

The ordinary rules on guardianship shall be merely suppletory except when the child is under substitute parental authority, or the guardian is a stranger, or a parent has remarried, in which case the ordinary rules on guardianship shall apply.

The default: parents manage jointly without a court appointment

Article 225 of the Family Code establishes that the father and mother jointly exercise legal guardianship over an unemancipated common child's property without needing a court appointment. This is automatic. No petition, no hearing, no letters of guardianship. The parents are the guardians by operation of law. In case of disagreement between them, the father's decision prevails unless a court has ordered otherwise. This arrangement covers the ordinary case — two living, married parents managing a young child's property together.

The three exceptions where ordinary rules fully apply

The statute then carves out three situations where the ordinary guardianship rules are not merely supplementary but fully applicable: (1) the child is under substitute parental authority — meaning neither parent has custody or both are incapacitated; (2) the guardian is a stranger — someone outside the family hierarchy; or (3) a parent has remarried. The remarriage exception is practically important: when a parent brings a stepparent into the picture, the law does not extend the automatic guardianship to that new arrangement. Full guardianship proceedings may be needed.

The bond requirement when property is substantial

Even within the automatic parental guardianship, there is a threshold. Where the market value of the child's property or the child's annual income exceeds P50,000, the parent must furnish a bond — not less than ten percent of the property's value or the annual income, as the court determines. A verified petition for approval of that bond is filed in the court of the place where the child resides. Once the bond is in place, the proceeding becomes a summary special proceeding where obligations of general guardians are heard and resolved.

Why this matters if your situation has changed

If you are a remarried parent managing your child's property, the statute tells you that the ordinary guardianship framework applies to you — not just the informal parental arrangement. That means the procedural requirements for guardians, including court oversight and potentially a bond, come into play. Similarly, if you are a relative or friend caring for a child whose parents are absent or incapacitated, you are a stranger in the legal sense and full guardianship rules govern your authority over the child's assets. Understanding which framework applies prevents unauthorized acts that a court may later disallow.
