Concubinage Beyond the Conjugal Home: What the Supreme Court Ruled

The Supreme Court has ruled that a married man who cohabits with another woman can be convicted of concubinage even if the relationship does not take place in the conjugal home. The decision in Singgit and But-ay v. People of the Philippines clarifies that the location of the cohabitation is not the deciding factor—what matters is whether the couple lived together as husband and wife, with the woman knowing the man was married.

This ruling is significant for anyone facing marital disputes or criminal complaints involving infidelity. It confirms that avoiding the family home does not shield a spouse from liability under the Revised Penal Code.

The Facts of the Case

Ariel Cadayday Singgit, a married man, engaged in a relationship with Genivieve Mayondo But-ay. The couple cohabited and had a child together. Witnesses testified that Ariel introduced Genivieve to neighbors as his new wife, and Genivieve herself admitted to living with Ariel in Mindanao.

The prosecution charged both with concubinage. The Information stated that the couple cohabited in a "private dwelling," rather than the "conjugal dwelling." The defense argued this made the charge defective, claiming that concubinage could only occur in the family home.

The Legal Definition of Concubinage

The Revised Penal Code defines concubinage as committed by a husband who:

1. Keeps a mistress in the conjugal dwelling;
2. Has sexual intercourse under scandalous circumstances with a woman who is not his wife; or
3. Cohabits with her in any other place.

The elements of the crime are: (1) the man must be married; (2) he commits any of the three acts above; and (3) the woman must know that he is married.

The concubine faces the penalty of destierro (banishment from a specified radius), while the husband faces prisión correccional in its minimum and medium periods.

What "Cohabitation" Means

The Supreme Court explained that cohabitation means dwelling together in the manner of husband and wife for some period of time. This is different from occasional or transient encounters for unlawful intercourse. Whether a relationship constitutes an unlawful assumption of the conjugal relation is a question of fact, determined by the court's assessment of the evidence.

In this case, the prosecution's evidence—including witness testimonies and Genivieve's own admissions—proved beyond reasonable doubt that the couple lived together as husband and wife.

Why the "Private Dwelling" Argument Failed

The defense argued that the Information was defective because it used "private dwelling" instead of "conjugal dwelling." The Supreme Court rejected this argument. The Court held that an Information is sufficient if it enables a person of common understanding to know the offense charged, prepare a defense, and allows the court to render proper judgment.

The Court emphasized that the third mode of committing concubinage—cohabitation in any other place—was sufficiently proven. The distinction between "private" and "conjugal" dwelling was immaterial. The crime hinges on the assault to the marital vow and the attack on the family caused by the spouse's infidelity, not the specific location of the relationship.

The Penalty Imposed

The Court affirmed the conviction but modified the husband's sentence under the Indeterminate Sentence Law. He was sentenced to imprisonment ranging from two months and one day (arresto mayor) as minimum, to six months as maximum. The woman's penalty of destierro was affirmed.

Practical Takeaways

• Location does not matter. Cohabitation in any place—a private dwelling, an apartment, or another city—can constitute concubinage if the other elements are present.
• The woman's knowledge is essential. A woman cannot be convicted of concubinage unless she knew the man was married at the time of the relationship.
• Evidence of cohabitation is key. Witness testimonies, admissions, and even the birth of a child can establish that a couple lived together as husband and wife.
• The Information need not be perfect. Minor deviations in wording, such as "private dwelling" instead of "conjugal dwelling," will not invalidate a charge if the substance of the offense is clearly stated.
• The crime protects the family. Philippine law treats concubinage as an attack on the marital vow and the family institution, warranting criminal penalties.
