The Philippines adheres to a strictly monogamous system of marriage, enshrined in the Family Code of the Philippines (Executive Order No. 209, as amended). Article 1 of the Family Code defines marriage as “a special contract of permanent union between a man and a woman entered into in accordance with law for the establishment of conjugal and family life.” This principle underpins both criminal and civil prohibitions against entering a second marriage while a prior valid marriage subsists. Bigamy and its civil consequences remain among the most litigated areas of family law, affecting property relations, legitimacy of children, inheritance rights, and criminal liability. This article comprehensively examines the legal framework, elements of the offense, exceptions, procedural requirements, civil effects, special considerations, and broader implications under Philippine law.

The Crime of Bigamy under the Revised Penal Code

Bigamy is criminalized under Article 349 of the Revised Penal Code (Act No. 3815), which states:
“The penalty of prision mayor shall be imposed upon any person who shall contract a second or subsequent marriage before the legal dissolution of the first marriage has taken place.”

The four essential elements of the crime are:

The offender has a legally subsisting first marriage.
The first marriage has not been legally dissolved or, in proper cases, the absent spouse has not been judicially declared presumptively dead.
The offender contracts a second or subsequent marriage.
The second marriage would have been valid had it not been for the existence of the first.

The offense is committed the moment the second marriage ceremony is performed, regardless of consummation or cohabitation. Both men and women may be principals. Related offenses include illegal marriage under Article 350 (contracting marriage against legal provisions) and the crimes of adultery (Article 333) or concubinage (Article 334) committed by the first spouse against the second union.

The penalty is prision mayor in its medium and maximum periods (six years and one day to twelve years). As an afflictive penalty, the crime prescribes in fifteen years under Article 90 of the Revised Penal Code. The prescriptive period begins to run from the date the offended party (usually the first spouse) acquires knowledge of the second marriage.

Bigamy is generally classified as a public crime that may be prosecuted upon complaint of the offended party or motu proprio by the public prosecutor once probable cause is established. Venue lies in the place where the second marriage was celebrated or where the criminal information is filed.

Civil Nullity of Bigamous Marriages under the Family Code

Article 35(4) of the Family Code declares that a marriage contracted while a previous marriage is subsisting is void ab initio, except in the case provided in Article 41. A void marriage produces no legal effects from the beginning. No judicial decree is theoretically required to declare its nullity, yet for purposes of remarriage, Article 40 mandates that “the absolute nullity of a previous marriage may be invoked for purposes of remarriage on the basis solely of a final judgment declaring such previous marriage void.”

This rule, consistently upheld by the Supreme Court, prevents parties from unilaterally concluding that their first marriage is void (for instance, due to lack of marriage license, absence of parental consent, or psychological incapacity) and proceeding to remarry without a court declaration. Failure to obtain such a declaration before entering a second marriage exposes the party to criminal liability for bigamy even if the first marriage is later proven void.

Exceptions and Lawful Paths to Remarriage

Philippine law recognizes limited circumstances under which a second marriage may be valid despite a prior union:

Presumption of Death (Article 41, Family Code)
A subsequent marriage is valid if the absent spouse has been missing for four consecutive years (or two years if the disappearance occurred in a situation of danger of death) and the present spouse has a well-founded belief that the absent spouse is dead. A summary proceeding for declaration of presumptive death must be filed and granted. If the absent spouse reappears, the second marriage is automatically terminated upon recording of an affidavit of reappearance; however, any children born before termination retain their legitimacy, and property relations are governed by the rules on dissolution.
Judicial Declaration of Nullity or Annulment of the First Marriage
Once a final judgment declares the first marriage null and void (under Article 36 for psychological incapacity, Article 45 for voidable marriages, or other grounds in Article 35), the parties regain capacity to remarry. The judgment must be recorded in the appropriate civil registry.
Recognition of Foreign Divorce
Under the second paragraph of Article 26 of the Family Code (as interpreted by the Supreme Court in landmark rulings), a Filipino citizen whose alien spouse obtains a valid divorce abroad may remarry. The divorce must be valid under the national law of the alien spouse and must capacitate the alien to remarry. Purely Filipino couples cannot obtain absolute divorce domestically.

Civil and Property Consequences of a Bigamous Second Marriage

Because the second marriage is void ab initio, the parties do not acquire the status of husband and wife. Specific effects include:

Property Relations: No absolute community of property or conjugal partnership of gains arises. If at least one party entered the second marriage in good faith (believing the first marriage had been dissolved), the property regime is governed by Article 147 or 148 of the Family Code (co-ownership of properties acquired through joint effort). If both parties are in bad faith, all donations and benefits are forfeited in favor of innocent third parties or the children, and any acquisitions are treated as separate property.
Legitimacy of Children: Children conceived or born before a final judgment of nullity of the second marriage are generally considered illegitimate. However, courts have applied the doctrine of putative marriage in limited good-faith scenarios to grant certain rights. Support obligations toward such children arise from filiation, not from the void marriage itself.
Inheritance Rights: The second “spouse” is not a compulsory or legal heir. Wills naming the second spouse as beneficiary remain valid as testamentary dispositions, but intestate succession rights are denied.
Support and Other Rights: There is no mutual obligation of support between the parties to the void marriage. Insurance beneficiaries, joint bank accounts, and other spousal privileges are not recognized.

Procedural Requirements and Remedies

A party wishing to remarry must first secure:

A final judgment of nullity or annulment of the first marriage, or
A declaration of presumptive death, or
Recognition of a foreign divorce (where applicable).

The judgment must be annotated in the marriage certificate and civil registry. Failure to record the judgment renders any subsequent marriage legally defective.

For the bigamous marriage itself, a petition for declaration of absolute nullity may be filed by either party or by the first spouse. The first spouse may also seek criminal prosecution for bigamy and, simultaneously or separately, file an action for damages.

Special Considerations

Muslim Filipinos
Under Presidential Decree No. 1083 (Code of Muslim Personal Laws), a Muslim man may contract up to four marriages simultaneously provided he can treat all wives with equal justice and obtains the consent required by Islamic law. Polygamy is thus lawful for Muslims and does not constitute bigamy under the Revised Penal Code. Non-Muslims marrying Muslims remain subject to the Family Code’s monogamous rule unless both parties are Muslims.

Overseas Filipino Workers and Mixed Marriages
Filipinos who contract a second marriage abroad while their Philippine marriage subsists remain liable for bigamy upon return, as Philippine criminal law follows the offender (territoriality with exceptions). Foreign marriages valid under the lex loci celebrationis are recognized only if they do not violate Philippine public policy against bigamy.

Public Officers and Administrative Liability
Government employees or members of the Armed Forces who contract bigamous marriages face administrative charges for immorality, grave misconduct, or conduct prejudicial to the service, often resulting in dismissal. The Civil Service Commission and military tribunals apply these sanctions independently of criminal proceedings.

Effects on Third Parties and Public Records
Bigamy complicates titles to real property, passports, visas, tax filings, and social security benefits. Banks, insurance companies, and government agencies require proof of valid marital status before recognizing spousal rights.

Defenses to Bigamy Charges

Common defenses include:

The first marriage was already dissolved by death or valid foreign divorce.
A prior final judgment of nullity existed before the second marriage (even if not recorded).
The second marriage was itself void for reasons independent of bigamy.
The prescriptive period had lapsed.
Lack of criminal intent (rarely successful).

Mere belief that the first marriage was void, without a judicial declaration, is not a defense.

Conclusion

The Philippine legal system treats second marriages during the subsistence of a prior valid union with severe criminal and civil sanctions to uphold the sanctity and stability of marriage. Parties contemplating remarriage must navigate mandatory judicial proceedings for nullity, annulment, or presumptive death. Ignorance of these requirements exposes individuals to long-term imprisonment, forfeiture of property rights, and illegitimacy of offspring. Compliance with the Family Code and Revised Penal Code remains the only pathway to a legally secure subsequent marriage.
