Concubinage Laws in the Philippines

I. Introduction

Concubinage is a criminal offense under Philippine law committed by a married man who maintains a sexual or quasi-marital relationship with a woman other than his wife under circumstances specifically punished by the Revised Penal Code. It is one of the so-called “crimes against chastity,” alongside adultery, seduction, acts of lasciviousness, and related offenses.

In the Philippines, concubinage remains a controversial offense because of the unequal legal treatment between husbands and wives. A married woman may be charged with adultery for a single act of sexual intercourse with a man who is not her husband. By contrast, a married man commits concubinage only when the relationship falls within one of the specific situations enumerated by law. This difference has long been criticized as a reflection of outdated gender norms in criminal law.

II. Governing Law

Concubinage is punished under Article 334 of the Revised Penal Code.

Under Article 334, a husband commits concubinage when he does any of the following:

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 woman who participates in the relationship may also be held criminally liable if she knew that the man was married.

III. Elements of Concubinage

To establish concubinage, the prosecution must generally prove the following:

1. The man is legally married;
2. He committed one of the acts punished by Article 334;
3. The woman involved is not his wife;
4. The relationship falls within one of the legally recognized modes of concubinage; and
5. The offended wife filed the complaint, unless legally excused or otherwise permitted under procedural rules.

Concubinage is not committed merely because a married man was unfaithful. The law requires proof that his conduct falls into one of the specific modes stated in Article 334.

IV. The Three Modes of Committing Concubinage

A. Keeping a Mistress in the Conjugal Dwelling

The first mode is committed when a married man keeps his mistress in the conjugal dwelling. The “conjugal dwelling” generally refers to the home where the spouses live or are supposed to live as husband and wife.

This mode is especially offensive under the law because it brings the illicit relationship directly into the marital home. The prosecution must show more than a casual visit. The evidence should establish that the mistress was maintained or kept in the conjugal dwelling in a manner showing a continuing illicit relationship.

B. Sexual Intercourse Under Scandalous Circumstances

The second mode is committed when a married man has sexual intercourse with a woman who is not his wife under scandalous circumstances.

The phrase “scandalous circumstances” means that the affair was conducted in a way that caused public scandal, disgrace, or outrage. This does not necessarily require that the sexual act itself be publicly seen, but the circumstances must be such that the relationship becomes offensive to public morals or public decency.

Examples may include situations where the man openly displays the illicit relationship, introduces the woman as his partner despite being married, or engages in behavior that exposes the affair to public humiliation or scandal.

Mere suspicion, private infidelity, or secret sexual relations may not be enough under this mode unless scandalous circumstances are shown.

C. Cohabiting With the Mistress in Any Other Place

The third mode is committed when the married man cohabits with a woman who is not his wife in a place other than the conjugal dwelling.

Cohabitation means more than occasional meetings or isolated sexual encounters. It implies living together as husband and wife, or maintaining a continuing domestic relationship that resembles marital life. Evidence may include shared residence, shared household expenses, public representation as a couple, testimony of neighbors, photographs, messages, lease documents, or other proof showing a continuing arrangement.

This is often the most commonly alleged form of concubinage because many extramarital relationships involve the married man living with, supporting, or regularly staying with another woman.

V. Who May File a Complaint

Concubinage is a private crime. It generally cannot be prosecuted unless the offended spouse files the required complaint.

The offended party is the wife of the married man. The complaint must include both the husband and the woman involved, if both are alive and can be prosecuted. The wife generally cannot choose to prosecute only one of them when both are legally liable.

This rule exists because the offense is considered an offense against marital fidelity and family honor, and the law gives the offended spouse control over whether criminal prosecution should proceed.

VI. Effect of Pardon or Consent

A complaint for concubinage may be barred if the offended wife consented to or pardoned the offense.

A. Consent

Consent refers to permission given before or during the commission of the offense. If the wife knowingly allowed the relationship, the husband may raise consent as a defense.

B. Pardon

Pardon refers to forgiveness after the offense has been committed. For pardon to bar prosecution, it must generally be extended to both offenders—the husband and the mistress—when both are guilty and available for prosecution.

Pardon must be clear. Courts do not lightly presume it. Mere delay in filing a complaint does not automatically amount to pardon, although it may affect the credibility of the case depending on the facts.

VII. Penalties for Concubinage

The penalties under Article 334 are unequal as between the husband and the mistress.

The married man may be punished with prisión correccional in its minimum and medium periods.

The mistress is punished with destierro.

A. Prisión Correccional

Prisión correccional is a correctional penalty under the Revised Penal Code. Depending on the period applied, it may involve imprisonment within the range provided by the Code.

B. Destierro

Destierro is not imprisonment. It is a penalty of banishment. A person sentenced to destierro is prohibited from entering certain places designated by the court, usually within a specified radius from the offended party or a particular location.

Destierro is commonly misunderstood as a light penalty. While it does not involve confinement in jail, it still restricts liberty and movement and carries criminal consequences.

VIII. Concubinage Compared With Adultery

Concubinage and adultery are related but different offenses.

A. Adultery

Adultery is committed by a married woman who has sexual intercourse with a man who is not her husband, and by the man who has sexual intercourse with her knowing she is married.

Each act of sexual intercourse may constitute a separate act of adultery.

B. Concubinage

Concubinage is committed by a married man only when he:

1. Keeps a mistress in the conjugal dwelling;
2. Has sexual intercourse under scandalous circumstances; or
3. Cohabits with her elsewhere.

Thus, adultery is generally easier to prove because a single sexual act may be enough. Concubinage requires proof of one of the specific statutory circumstances.

C. Unequal Treatment

The law imposes stricter criminal liability on wives than on husbands. This disparity has been widely criticized as discriminatory and inconsistent with modern principles of gender equality, marital fairness, and equal protection.

IX. Evidence in Concubinage Cases

Concubinage may be proven by direct or circumstantial evidence.

Direct evidence of sexual intercourse is rare. Courts often rely on circumstantial evidence showing the existence of an illicit relationship and the circumstances required by law.

Possible evidence includes:

1. Testimony of the wife, relatives, neighbors, or household staff;
2. Photographs or videos;
3. Messages, emails, or social media posts;
4. Birth records of children allegedly born from the relationship;
5. Lease contracts or property documents;
6. Hotel records, travel records, or receipts;
7. Public declarations or representations as a couple;
8. Evidence that the husband and mistress live together;
9. Proof that the mistress stayed in the conjugal dwelling; and
10. Circumstances showing public scandal.

However, evidence must be legally obtained. Illegally obtained private communications, unauthorized recordings, hacking, or unlawful surveillance may create separate legal problems and may be challenged in court.

X. Defenses in Concubinage Cases

Common defenses include:

A. The Man Was Not Legally Married

Concubinage requires a valid existing marriage. If the marriage is void, legally dissolved, or otherwise not legally existing at the time of the alleged offense, this may affect criminal liability. However, parties should be careful because questions involving nullity of marriage require judicial determination.

B. No Cohabitation

If the charge is based on cohabitation, the defense may argue that the relationship consisted only of visits, meetings, or isolated encounters and did not amount to living together as husband and wife.

C. No Scandalous Circumstances

If the charge is based on sexual intercourse under scandalous circumstances, the defense may argue that the relationship was private and did not create public scandal within the meaning of the law.

D. The Woman Did Not Know the Man Was Married

The mistress may defend herself by showing that she did not know the man was married. Knowledge of the man’s married status is important for her criminal liability.

E. Consent or Pardon

The accused may argue that the offended wife consented to the relationship or pardoned the offenders.

F. Insufficient Evidence

As in all criminal cases, guilt must be proven beyond reasonable doubt. Suspicion, jealousy, rumors, or moral certainty unsupported by competent evidence is not enough.

XI. Procedural Considerations

Because concubinage is a private crime, the filing of the proper complaint by the offended wife is essential.

The complaint should be carefully drafted to identify the specific mode of concubinage being charged. A vague accusation of “having a mistress” may be insufficient if it does not allege the facts necessary under Article 334.

The offended wife should also consider whether related civil, family, or protection remedies may be available, especially where the conduct involves abuse, abandonment, economic deprivation, or psychological violence.

XII. Relationship With Violence Against Women and Children Laws

Concubinage is not the only possible legal issue arising from a husband’s extramarital relationship.

Under Philippine law, a husband’s marital infidelity may, depending on the circumstances, also be relevant under laws protecting women and children, particularly when the conduct causes psychological abuse, economic abuse, humiliation, coercion, or emotional suffering.

A wife may consider remedies under laws addressing violence against women and their children when the facts show mental, emotional, economic, or psychological harm. These remedies are distinct from concubinage and may involve different elements, procedures, penalties, and protective measures.

XIII. Civil and Family Law Implications

Concubinage may also have consequences outside criminal law.

Possible civil or family law implications include:

1. Legal separation;
2. Support disputes;
3. Custody issues;
4. Property disputes;
5. Claims involving conjugal or community property;
6. Disinheritance issues in proper cases;
7. Damages, depending on the facts;
8. Protection orders where abuse is present; and
9. Issues involving children born from the extramarital relationship.

Concubinage itself does not automatically dissolve a marriage. The Philippines does not generally allow divorce for most marriages, subject to specific exceptions under special laws. A spouse seeking to end or alter marital status must pursue the proper remedy, such as declaration of nullity, annulment, legal separation, recognition of foreign divorce where applicable, or other appropriate proceedings.

XIV. Limitations and Criticism of the Law

Concubinage law has been criticized for several reasons.

First, it treats husbands and wives differently. A wife may be prosecuted for adultery based on a single sexual act, while a husband is liable for concubinage only under more specific and harder-to-prove circumstances.

Second, the law reflects an older view of marriage, chastity, and gender roles. It belongs to a class of crimes historically associated with protecting family honor rather than individual equality.

Third, it may be difficult to prove. Many extramarital affairs do not occur in the conjugal dwelling, are not conducted under scandalous circumstances, and may not involve clear cohabitation.

Fourth, criminal prosecution may not always address the deeper family problems caused by infidelity, such as financial abandonment, emotional abuse, child support issues, or property misuse.

For these reasons, some legal reform advocates have called for the review, amendment, or repeal of gender-discriminatory provisions in criminal law.

XV. Practical Considerations Before Filing a Case

Before filing a concubinage complaint, the offended wife should consider:

1. Whether the husband is legally married to her;
2. Which mode of concubinage applies;
3. Whether there is sufficient evidence;
4. Whether the alleged mistress knew the man was married;
5. Whether there was prior consent or pardon;
6. Whether the complaint must include both offenders;
7. Whether related remedies may be more effective;
8. The emotional, financial, and family consequences of litigation;
9. The impact on children; and
10. The possibility of settlement, protection, support, or family court remedies.

Criminal prosecution can be stressful, lengthy, and emotionally difficult. It may also affect ongoing family disputes. Legal advice is usually necessary before taking formal action.

XVI. Frequently Asked Questions

1. Is having a mistress automatically concubinage?

No. A married man does not automatically commit concubinage simply because he has a mistress. The conduct must fall under one of the three modes under Article 334: keeping a mistress in the conjugal dwelling, having sexual intercourse under scandalous circumstances, or cohabiting with her elsewhere.

2. Can a single sexual encounter amount to concubinage?

Possibly, but only if it occurred under scandalous circumstances. Unlike adultery, concubinage generally requires more than proof of a single private sexual act.

3. Can the mistress be charged?

Yes, if she knew that the man was married and participated in the relationship punished by law.

4. Can the wife charge only the mistress?

Generally, no. If both the husband and mistress are alive and subject to prosecution, the complaint should include both.

5. What if the wife forgave the husband?

Pardon may bar prosecution if it is legally valid. Generally, pardon must apply to both offenders, not only one.

6. Is destierro imprisonment?

No. Destierro is banishment from a certain place or area. It is not jail time, but it is still a criminal penalty.

7. Can text messages prove concubinage?

They may help prove the relationship, but they may not be enough by themselves. The prosecution must still prove the specific elements of concubinage. The messages must also be legally obtained and admissible.

8. Can a husband file concubinage against his wife?

No. Concubinage applies to a married man. A husband’s possible criminal complaint against an unfaithful wife would generally be adultery, not concubinage.

9. Can a wife file both concubinage and a case for psychological abuse?

Depending on the facts, different remedies may be available. Concubinage and psychological abuse have different legal elements and purposes. A lawyer should assess which remedy or combination of remedies is appropriate.

10. Does concubinage dissolve the marriage?

No. A criminal conviction for concubinage does not automatically dissolve the marriage. Separate family law proceedings are required to affect marital status.

XVII. Conclusion

Concubinage in the Philippines is a criminal offense rooted in marital fidelity, family honor, and traditional concepts of chastity. It punishes a married man who keeps a mistress in the conjugal dwelling, has sexual intercourse under scandalous circumstances, or cohabits with a woman who is not his wife.

Although still part of Philippine criminal law, concubinage is limited, difficult to prove, and widely criticized for treating husbands and wives unequally. In modern practice, a wife affected by a husband’s infidelity should consider not only concubinage but also related remedies involving support, custody, property, psychological abuse, protection orders, and family law proceedings.

Concubinage remains legally significant, but it should be understood within the broader context of Philippine criminal law, family law, women’s rights, and the continuing debate over gender equality in the justice system.
