The father and the mother shall jointly exercise legal guardianship over the property of the unemancipated common child without the necessity of a court appointment. In case of disagreement, the father's decision shall prevail, unless there is a judicial order to the contrary.
Where the market value of the property or the annual income of the child exceeds P50,000, the parent concerned shall be required to furnish a bond in such amount as the court may determine, but not less than ten per centum (10%) of the value of the property or annual income, to guarantee the performance of the obligations prescribed for general guardians.
A verified petition for approval of the bond shall be filed in the proper court of the place where the child resides, or, if the child resides in a foreign country, in the proper court of the place where the property or any part thereof is situated.
The petition shall be docketed as a summary special proceeding in which all incidents and issues regarding the performance of the obligations referred to in the second paragraph of this Article shall be heard and resolved.
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. (320a)
