SUBJECT: The Rule on ‘Bigamous and Polygamous Marriages’

I. Introduction

This memorandum exhaustively examines the Philippine legal framework governing bigamous and polygamous marriages. The analysis centers on the absolute prohibition of such unions under the Family Code of the Philippines, their constitutive elements, legal effects, and the attendant criminal and civil liabilities. The discussion will differentiate between bigamy as a criminal offense and the concept of a polygamous marriage as a void marital contract, while also addressing related doctrines such as the void ab initio status of subsequent marriages and the limited exceptions recognized under the Code of Muslim Personal Laws.

II. Statement of Applicable Laws and Doctrines

The primary legal sources are:

The Family Code of the Philippines (Executive Order No. 209, as amended), specifically Articles 1, 35, 41, 52, and the provisions on void marriages.

The Revised Penal Code, specifically Article 349 on the crime of Bigamy.

The Code of Muslim Personal Laws (Presidential Decree No. 1083), which provides a distinct regime for qualified Muslims.

Relevant jurisprudence from the Supreme Court, including the doctrines on psychological incapacity and the presumption of death.

III. Definition and Essential Elements of a Valid Marriage

Under Article 1 of the Family Code, marriage is defined 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.” Its essential requisites, the absence of which renders the marriage void ab initio (Article 35), are: (1) legal capacity of the contracting parties; (2) their consent freely given in the presence of a solemnizing officer; and (3) authority of the solemnizing officer and a valid marriage license, except in certain authorized cases. The requirement of legal capacity inherently includes the absence of a prior existing marriage.

IV. Bigamous Marriages: Concept and Legal Characterization

A bigamous marriage occurs when one of the contracting parties, at the time of the celebration of a subsequent marriage, is still validly married to another person. This subsequent marriage is classified as a void marriage under Article 35(4) of the Family Code. It is void ab initio, meaning it is considered legally non-existent from the very beginning. No judicial declaration is required for its nullity; any interested party may invoke its nullity at any time, even after the death of either party (Article 40, Family Code). The prior existing marriage must be valid and subsisting; if the first marriage is itself void, the subsequent union is not bigamous.

V. The Crime of Bigamy

The act of contracting a bigamous marriage constitutes the felony of Bigamy under Article 349 of the Revised Penal Code. The elements are: (a) the offender has been legally married; (b) the first marriage has not been legally dissolved, or, in cases where the spouse has been absent for a consecutive period of seven years, the absent spouse has not been judicially declared presumptively dead; (c) the offender contracts a second or subsequent marriage; and (d) the second or subsequent marriage has all the essential requisites for validity. Good faith is not a defense to the criminal charge, though it may affect civil liabilities. The filing of a complaint for bigamy is a public crime which can be prosecuted de officio by the State.

VI. Polygamous Marriages under the Civil Law Regime

In the general civil law context governed by the Family Code, polygamy—the practice of having more than one spouse simultaneously—is strictly prohibited. A polygamous marriage is one where a person, whether male or female, purports to marry another while a prior marriage remains undissolved. The Philippine legal system adheres to the principle of monogamy. Any marriage contracted during the subsistence of a valid marriage is void for being bigamous or polygamous. The term is often used interchangeably with bigamy, though polygamy can technically refer to multiple simultaneous spouses, while bigamy specifically denotes two.

VII. Comparative Table: Bigamous vs. Polygamous Marriages in Philippine Law

Aspect	Bigamous Marriage (Civil Law Context)	Polygamous Marriage (Muslim Personal Law Context)
Governing Law	Family Code of the Philippines and Revised Penal Code	Code of Muslim Personal Laws (P.D. 1083)
Legal Status	Void ab initio (Article 35(4), Family Code)	Potentially valid for qualified Muslims, subject to strict conditions (Article 27, CMPL)
Criminal Liability	Crime of Bigamy under Art. 349, Revised Penal Code	No criminal liability if performed in compliance with CMPL requirements
Essential Condition	Existence of a prior, valid, and subsisting marriage	Capacity of the husband to treat co-wives with equal companionship and just treatment (ma’ruf)
Who May Contract	Cannot be legally contracted by anyone under the Family Code	May be contracted only by a male Muslim who meets the requisite conditions (e.g., financial capacity, just treatment)
Judicial Declaration	Nullity can be invoked without judicial decree, but a declaration of nullity is needed for remarriage	Governed by specific rules in the Shari’a courts; a subsequent marriage without compliance is voidable or irregular (fasid)
Effect on Prior Marriage	Does not dissolve the first marriage; the first marriage remains valid	The first marriage remains valid, and the subsequent marriages are additional, simultaneous unions

VIII. Exceptions and Related Doctrines

Presumption of Death: Under Article 41 of the Family Code, a spouse may contract a subsequent marriage if the absent spouse has been missing for four consecutive years (or two years in case of a dangerous circumstance) and the present spouse has a well-founded belief that the absent spouse is already dead. A judicial declaration of presumptive death is required. If the absent spouse reappears, the subsequent marriage is automatically terminated, but the good faith of the present spouse is a defense to bigamy.

Psychological Incapacity: A declaration of nullity of the first marriage under Article 36 of the Family Code on grounds of psychological incapacity dissolves the marital bond ab initio for all legal intents and purposes. Once this becomes final and executory, a subsequent marriage is not bigamous.

Muslim Personal Laws: As illustrated in the comparative table, the Code of Muslim Personal Laws allows a qualified Muslim male to have more than one wife, up to a maximum of four, provided he can comply with the stringent requirements of justice and equality. This is a recognized exception to the general civil law rule of monogamy.

IX. Legal Effects and Consequences

Civil Effects: The bigamous or polygamous marriage (under civil law) produces no legal effect whatsoever between the parties. No community of property or conjugal partnership of gains arises. Children born from such a union are considered illegitimate children but are entitled to support and, under the Family Code and relevant rulings, may use the surname of the father if filiation is duly established. They have rights to succession as illegitimate children.

Criminal Liability: As stated, the guilty party (and the co-conspirator if they had knowledge of the existing marriage) may be prosecuted for bigamy.

Administrative and Professional Consequences: A conviction for bigamy may lead to administrative penalties for professionals and public officials, including possible disqualification from public office or disbarment for lawyers.

X. Conclusion and Recommendations

The rule on bigamous and polygamous marriages under the general civil law of the Philippines is one of strict prohibition, rendering such subsequent marriages void ab initio and punishable as a felony. The principle of monogamy is fundamental. The only operative exceptions are the presumption of death of a prior spouse under specific conditions and the separate system for Muslims under the Code of Muslim Personal Laws. For individuals in a bigamous marriage, the path is to seek a declaration of nullity from the court to formally establish the status of the void union and enable the possibility of a valid remarriage, provided all legal impediments are removed. Legal counsel must always ascertain the validity of a prior marriage before proceeding with any subsequent marital contract.
