In the Philippines, the legal system treats marital infidelity through two distinct lenses: criminal prosecution for the act of cheating and civil litigation for the purpose of legal separation. Because the Philippines remains the only country (aside from the Vatican) without a divorce law, understanding these specific legal avenues is crucial for aggrieved spouses.
1. Criminal Prosecution: Adultery vs. Concubinage
Under the Revised Penal Code (RPC), marital infidelity is classified as a crime against chastity. However, the law distinguishes between a wife’s infidelity and a husband’s infidelity, both in definition and in the burden of proof.
Adultery (Article 333)
Adultery is committed by a married woman who has sexual intercourse with a man not her husband, and by the man who has carnal knowledge of her knowing her to be married.
- The Threshold: A single act of sexual intercourse is sufficient to file a case.
- Penalty: Prision correccional in its medium and maximum periods.
Concubinage (Article 334)
Concubinage is committed by a married man under much stricter conditions. To convict a husband, the wife must prove one of the following:
- He keeps a mistress in the conjugal dwelling.
- He has sexual intercourse under scandalous circumstances.
- He cohabits with her in any other place.
- The Threshold: Unlike adultery, a "one-night stand" typically does not qualify as concubinage unless it meets the "scandalous circumstances" criteria.
- Penalty: The husband faces prision correccional in its minimum and medium periods, while the concubine is only served with destierro (banishment from a specific radius).
Important Note: In both cases, the offended spouse must include both the guilty spouse and the third party in the complaint. The case cannot proceed if the offended spouse has consented to the infidelity or has pardoned the guilty parties.
2. Legal Separation (Civil Case)
Legal separation is governed by the Family Code of the Philippines. Unlike an annulment or a declaration of nullity, legal separation does not dissolve the marriage bond. The parties remain married and cannot remarry, but they are allowed to live separately and their properties are divided.
Grounds for Legal Separation (Article 55)
A petition may be filed based on several grounds, including but not limited to:
- Sexual infidelity or perversion.
- Repeated physical violence or grossly abusive conduct.
- Attempt to corrupt or induce the spouse or a child to engage in prostitution.
- Final judgment sentencing the respondent to imprisonment of more than six years.
- Drug addiction or habitual alcoholism.
- Abandonment of the petitioner without justifiable cause for more than one year.
The "Cooling-Off" Period
The law mandates a six-month cooling-off period between the filing of the petition and the start of the trial. This is intended to encourage reconciliation between the spouses.
3. Comparison of Remedies
| Feature | Criminal (Adultery/Concubinage) | Civil (Legal Separation) |
|---|---|---|
| Objective | Imprisonment/Punishment | Separation of bed and board |
| Marital Bond | Remains intact | Remains intact |
| Property | No automatic effect | Dissolution of absolute community/conjugal partnership |
| Custody | May affect fitness | Court determines best interest of the child |
| Standard of Proof | Proof beyond reasonable doubt | Preponderance of evidence |
4. Legal Consequences and Effects
Once a decree of legal separation is issued, several legal shifts occur:
- Right to Cohabit: The spouses are entitled to live separately.
- Property Relations: The absolute community or conjugal partnership is dissolved and liquidated. The "offending spouse" loses their right to a share of the net profits of the conjugal property.
- Custody: The innocent spouse is usually awarded custody of minor children, subject to the "Tender Age Rule" (children under 7 generally stay with the mother unless she is unfit).
- Succession: The offending spouse is disqualified from inheriting from the innocent spouse by intestate succession. Moreover, provisions in a will in favor of the offending spouse are revoked by operation of law.
5. Defenses and Bars to Action
A petition for legal separation or a criminal complaint may be dismissed if any of the following are proven:
- Condonation: The implied or expressed forgiveness of the offense (e.g., continuing to sleep in the same bed after discovery).
- Consent: The innocent spouse agreed to the infidelity beforehand.
- Connivance: The innocent spouse set up the situation to catch the other.
- Recrimination: Both parties have given ground for legal separation (the "clean hands" doctrine).
- Collusion: The parties agreed to manufacture grounds to get a decree.
- Prescription: A petition for legal separation must be filed within five years from the time of the occurrence of the cause.
