In the Philippine legal system, the care and custody of minors are governed by the principle of the "best interests of the child." While parents are considered the natural guardians of their children under the Family Code, certain circumstances—such as the death, absence, or incapacity of the parents—necessitate the judicial appointment of a legal guardian. This process is primarily governed by A.M. No. 03-02-05-SC, also known as the Rule on Guardianship of Minors.

1. Nature of Guardianship

Guardianship is a trust relationship where one person (the guardian) is legally authorized to care for the person and/or manage the property of another (the ward) who is unable to do so due to age or other legal disability.

There are two primary types of court-appointed guardians:

Guardian of the Person: Responsible for the minor’s care, custody, and education.
Guardian of the Property: Responsible for the management and preservation of the minor’s assets or estate.
General Guardian: A person appointed to care for both the person and the property of the ward.

2. Who May Petition for Guardianship

Under the Rule, any relative, friend, or other person on behalf of the minor may file a petition. Additionally, the minor themselves may petition for the appointment of a guardian if they are at least fourteen (14) years of age.

The Department of Social Welfare and Development (DSWD) or similar local social welfare offices may also initiate the petition if no suitable private individual is available or willing to act.

3. Jurisdiction and Venue

The petition must be filed in the Family Court of the province or city where the minor actually resides. If the minor resides outside the Philippines but has property within the country, the petition is filed in the Family Court of the location where the property is situated.

4. Contents of the Petition

A formal petition for guardianship must be verified and must state the following essential facts:

The jurisdictional facts (residency of the minor).
The name, age, and residence of the minor.
The names and residences of the next of kin and those having the minor in their care.
The probable value and character of the minor’s estate (if applying for guardianship of property).
The grounds for the appointment (e.g., death of parents, abandonment, or parental incapacity).
The name, age, and residence of the person for whom letters of guardianship are prayed.

5. Factors for Selecting a Guardian

The court exercises wide discretion in choosing a guardian, prioritizing the minor's welfare. The court considers:

Moral character and physical/mental health of the proposed guardian.
Financial capability to manage the minor's property.
Relationship and degree of intimacy with the minor.
The preference of the minor, if the child is over 14 years old, provided the choice is suitable.

6. The Procedural Steps

I. Filing and Notice of Hearing

Once the petition is filed, the court sets a time and place for the hearing. The court issues a notice to the persons named in the petition (relatives, custodians) and the minor themselves if they are 14 years or older.

II. The Hearing and Opposition

At the hearing, any interested person may contest the petition by filing a written opposition. They may argue that the appointment is unnecessary or that the proposed guardian is unfit.

III. The Order of Appointment

If the court finds that the allegations are true and that the appointment is necessary for the minor's welfare, it will issue an order appointing the guardian.

IV. The Guardian’s Bond

Before the "Letters of Guardianship" are issued, the appointed guardian of the property must post a bond in an amount fixed by the court. This bond ensures that the guardian will faithfully perform their duties and protect the minor’s assets.

Note: A bond is generally not required for a guardian who only manages the "person" of the minor, unless the court directs otherwise.

V. Oath and Letters of Guardianship

Upon posting the bond and taking an oath of office, the court issues the Letters of Guardianship, which serves as the official authority of the guardian to act on behalf of the minor.

7. Duties and Responsibilities

A court-appointed guardian is an officer of the court and is subject to its supervision. Key duties include:

Inventory: Within three months of appointment, the guardian must file an inventory of the minor’s real and personal estate.
Management: The guardian must manage the estate frugally and apply the income or principal for the comfortable support and education of the ward.
Accounting: The guardian must render an annual accounting of the estate to the court for approval.
Encumbrance: A guardian cannot sell or mortgage the minor's property without specific court approval (Petition for Sale or Encumbrance).

8. Termination of Guardianship

The guardianship is terminated under the following conditions:

Attainment of Majority: When the minor reaches 18 years of age.
Death of the Ward or Guardian: The relationship is personal and ends upon death.
Removal of the Guardian: The court may remove a guardian for residency outside the Philippines, embezzlement, mismanagement, or failure to render accounts.
Cessation of the Ground for Guardianship: If the reason for the appointment (e.g., parental incapacity) no longer exists.

Upon termination, the guardian must file a final accounting and move for the official discharge of the bond and the case.
