In the Philippine legal landscape, the sanctity of marriage is protected by the Constitution. However, the law also recognizes the harsh realities of abandonment and the disappearance of a spouse. Navigating these situations requires an understanding of the Family Code of the Philippines and relevant jurisprudence.

1. Defining Abandonment vs. Absence

While often used interchangeably in casual conversation, "abandonment" and "being missing" carry different legal implications.

Abandonment: Occurs when a spouse leaves the conjugal home without the intention of returning, fails to provide support, or refuses to comply with marital obligations for a significant period.
Absence (Missing Person): Refers to a situation where a spouse's whereabouts are unknown, and there is no news as to whether they are still alive.

2. Remedies for Abandonment

Under the Family Code, if a spouse abandons the other or fails to comply with marital obligations, the aggrieved spouse may seek judicial relief.

Judicial Separation of Property

If a spouse has abandoned the other for at least one year or has failed to comply with their obligations to the family, the aggrieved spouse may file a petition for the judicial separation of property. This protects the assets of the present spouse from being mismanaged or liquidated by the absconding partner.

Management of Conjugal Assets

Generally, the administration of the community property or conjugal partnership belongs to both spouses. However, if one spouse abandons the other, the present spouse may petition the court for sole administration of the properties.

Note: Abandonment is defined under Article 101 of the Family Code as leaving the conjugal dwelling without any intention of returning. A spouse who has left the home for three months or has failed to give information as to their whereabouts for the same period is prima facie presumed to have no intention of returning.

3. The Legal Status of a Missing Spouse

When a spouse disappears without a trace, the law provides a mechanism to allow the remaining spouse to move forward, particularly regarding remarriage.

Summary Proceeding for Declaration of Presumptive Death

Under Article 41 of the Family Code, for the purpose of remarriage, a spouse may file a summary proceeding to have the missing spouse declared presumptively dead. The requirements are:

The absent spouse has been missing for four consecutive years.
If the disappearance occurred under "danger of death" (e.g., a plane crash or shipwreck), the period is reduced to two years.
The present spouse has a well-founded belief that the absent spouse is dead.
The present spouse wishes to remarry.

The "Well-Founded Belief" Standard

The Supreme Court of the Philippines is strict regarding this requirement. The present spouse must prove they conducted a "diligent search." Simply waiting for the time to pass is insufficient; one must show efforts such as contacting relatives, reporting to authorities, and checking hospitals or morgues.

4. Reappearance of the Absent Spouse

If a spouse who was declared presumptively dead returns, the law prioritizes the truth of their survival over the legal fiction of their death.

Automatic Termination of the Second Marriage: The second marriage is automatically terminated upon the recording of an Affidavit of Appearance of the absent spouse in the civil registry of the place where they reside.
Status of Children: Children born of the second marriage (contracted while the first spouse was missing) remain legitimate, provided the second marriage was entered into in good faith.
Property Relations: The property regime of the second marriage will be dissolved and liquidated.

5. Abandonment as a Ground for Legal Separation

It is important to distinguish that abandonment is a ground for Legal Separation, but not for Annulment or Declaration of Nullity of Marriage.

Grounds: Under Article 55, "abandonment of petitioner by respondent without justifiable cause for more than one year" is a valid ground for legal separation.
Effect: A decree of legal separation entitles the spouses to live separately and dissolves the absolute community or conjugal partnership, but it does not sever the marital bond. Neither party can remarry.

6. Support and Criminal Liability

Abandonment is not merely a civil matter. Under Republic Act No. 9262 (Anti-Violence Against Women and Their Children Act), the deprivation of financial support and psychological distress caused by abandonment can be classified as economic or psychological violence.

Support: The present spouse can file for a "Petition for Support" to compel the abandoning spouse to provide for the family's needs, enforceable through a writ of execution or even a hold-departure order.
Criminal Charges: If the abandonment is accompanied by a deliberate refusal to provide support or is intended to cause mental anguish, criminal charges under RA 9262 may be pursued.
