In the Philippine legal landscape, infidelity is not merely a moral or civil issue; it is a criminal offense classified under Crimes Against Chastity in the Revised Penal Code (RPC). The law distinguishes between the acts committed by a wife and those committed by a husband, categorizing them as Adultery and Concubinage, respectively.
Understanding these distinctions is crucial, as the elements, burden of proof, and penalties vary significantly between the two.
1. Adultery (Article 333, RPC)
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 Elements of Adultery
For a successful prosecution of adultery, the following elements must be present:
- That the woman is legally married to the complainant.
- That she has sexual intercourse with a man other than her husband.
- That as regards the paramour, he must know that the woman is married at the time of the intercourse.
Key Characteristics
- Each sexual act is a separate crime: Adultery is not a "continuing" crime. Every single instance of sexual intercourse constitutes a separate count of adultery.
- Knowledge of the Paramour: The man involved can only be held liable if it is proven he knew the woman was married. If he was unaware of her marital status, only the wife is criminally liable.
2. Concubinage (Article 334, RPC)
Concubinage is committed by a married man under specific, narrow circumstances. Unlike adultery, simply having a "one-night stand" or an occasional fling does not constitute concubinage.
The Elements of Concubinage
A husband can only be convicted of concubinage if he performs any of the following:
- Keeping a mistress in the conjugal dwelling;
- Having sexual intercourse under scandalous circumstances; or
- Cohabiting (living together) with his mistress in any other place.
Key Characteristics
- Higher Burden of Proof: It is generally harder to convict a husband of concubinage than a wife of adultery because the law requires proof of "cohabitation" or "scandalous circumstances," rather than just a single act of intercourse.
- The Paramour: The mistress is also liable, but her penalty is significantly lighter than that of the husband.
3. Comparison: Adultery vs. Concubinage
| Feature | Adultery (Wife) | Concubinage (Husband) |
|---|---|---|
| Who commits it? | Married woman & her paramour. | Married man & his mistress. |
| Proof of Sex | A single act of intercourse is enough. | Intercourse alone is not enough (requires cohabitation/scandal/dwelling). |
| Penalty | Prision correccional (Medium and Maximum). | Prision correccional (Minimum and Medium). |
| Penalty for Partner | Same as the wife. | Destierro (Banishment). |
4. Evidence and Prosecution
Because sexual acts are usually performed in private, direct evidence (like eyewitness testimony of the act) is rare. The Philippine courts allow for circumstantial evidence, provided it is sufficiently strong.
Common Forms of Evidence:
- Admissions or Confessions: Written letters, texts, or social media messages acknowledging the relationship.
- Photographs and Videos: Visual proof of intimacy or cohabitation.
- Testimonies: Neighbors, security guards, or investigators testifying to the couple living together or acting as husband and wife.
- Public Records: Birth certificates of children born out of the illicit union where the father acknowledges paternity.
Who Can File?
Only the offended spouse can file the complaint. The complaint must be filed against both guilty parties (the spouse and the paramour/mistress) if they are both alive. You cannot choose to pardon one and sue the other.
5. Penalties and Consequences
The penalties for these crimes involve imprisonment and, in some cases, geographic restriction.
- Adultery: The wife and her paramour face prision correccional in its medium and maximum periods (typically 2 years, 4 months, and 1 day to 6 years).
- Concubinage: The husband faces prision correccional in its minimum and medium periods (typically 6 months and 1 day to 4 years and 2 months).
- The Mistress: She is sentenced to destierro. This is not imprisonment but a prohibition from entering a designated radius (25km to 250km) of a specific place for a period of time.
6. Important Legal Nuances
The "Pardon" Defense
If the offended spouse has consented to the infidelity or has pardoned the offenders (either expressly or impliedly by continuing to live with them), the criminal action will be dismissed.
Death Caused Under Exceptional Circumstances (Art. 247)
If a legally married person surprises their spouse in the act of committing sexual intercourse with another person and kills any or both of them in the act or immediately thereafter, the penalty is not imprisonment but destierro. This is a "justifying circumstance" based on the sudden impulse of passion and obfuscation.
Psychological Violence (R.A. 9262)
In modern practice, many offended wives opt to file cases under Republic Act 9262 (Anti-Violence Against Women and Their Children Act) instead of Concubinage. Infidelity is recognized as a form of psychological violence which causes emotional anguish, often carrying heavier penalties and offering more immediate protection (Permanent Protection Orders) than a standard Concubinage charge.
