When comparing adultery vs concubinage in the Philippines, many assume both are simply forms of marital infidelity punished the same way. However, under the Revised Penal Code, they are distinct crimes with different punishable acts and consequences. Understanding these differences is crucial whether you are considering legal action or simply want to know how the law addresses infidelity within marriage.
What is Concubinage in Philippine Law?
Under Article 334, concubinage is committed when a married man: (1) keeps a mistress in the conjugal dwelling, bringing another woman into the marital home; (2) has sexual intercourse under scandalous circumstances with a woman who is not his wife; or (3) cohabits with her elsewhere as if they were husband and wife.
- Who Must Be Charged? Both the husband and her mistress
- Proof Needed: To secure a conviction, it must be proven that the husband committed at least one of the acts above. Mere cheating in the form of suspicious messages, rumors, or emotional affairs is generally insufficient to establish concubinage.
- Who Must File the Case: Only the aggrieved wife may file the complaint for concubinage. The complaint must be executed personally under oath before the prosecutor. See our guide on how to file for concubinage.
- The Penalty: The husband faces prisión correccional in its minimum and medium periods, ranging from 6 months and 1 day to 4 years and 2 months, while the mistress is punished with destierro (banishment from a municipality or place). For a detailed breakdown of penalties, see our guide on concubinage penalties.
What is Adultery in Philippine Law?
Under Article 333, adultery is committed when a married woman engages in sexual relations with a man who is not her husband. The man may also be held liable if he knew that the woman was married at the time. Notably, liability may still arise even if the marriage is later declared void.
- Who Must Be Charged? Both the wife and her lover, provided the latter knew she was married.
- The Proof Needed: A single act of sexual intercourse is sufficient to establish liability.
- Who Must File the Case: Only the aggrieved husband may file the complaint for adultery. The complaint must be executed personally under oath before the prosecutor.
- The Penalty: prisión correccional in its medium and maximum periods, ranging from 2 years, 4 months and 1 day to 6 years.
Adultery vs Concubinage in the Philippines: Key Legal Differences
| Feature | Adultery (Wife) | Concubinage (Husband) |
|---|---|---|
| Primary Offender | Married woman | Married man |
| Proof Needed | Single act of sexual intercourse | Keeping a mistress in conjugal home, scandalous sex, or cohabitation elsewhere |
| Difficulty to Prove | Lower (easier to file) | Higher (harder to convict) |
| Third Party Penalty | Lover goes to prison | Mistress is banished (destierro) |
| Who May File | Aggrieved husband | Aggrieved wife |
| Penalty | Prisión correccional (2 yrs, 4 mo 1 day – 6 yrs) | Husband: Prisión correccional (6 mo 1 day – 4 yrs 2 mo); Mistress: destierro |
The table above shows the main legal differences between adultery and concubinage under the Philippine Revised Penal Code.
- Adultery is committed by a married woman. A single act of sexual intercourse is enough to establish liability, making it easier to prove. Both the wife and her lover face imprisonment.
- Concubinage is committed by a married man and is harder to prove, as it requires scandalous behavior—such as keeping a mistress in the conjugal home, engaging in public sexual acts, or cohabiting elsewhere. The husband faces imprisonment, while the mistress is only banished (destierro).
In short, adultery carries heavier penalties, affecting both parties severely, while concubinage focuses more on punishing the husband, reflecting historical gender norms in Philippine law. Understanding these distinctions is essential for anyone considering legal action or simply wanting to know how marital infidelity is treated under Philippine law.
