The Difference between ‘Bigamy’ and ‘Illegal Marriage’
| SUBJECT: The Difference between ‘Bigamy’ and ‘Illegal Marriage’ |
I. Introduction
This memorandum provides an exhaustive analysis of the distinction between the crimes of bigamy under Article 349 of the Revised Penal Code and illegal marriage under Article 350 of the Revised Penal Code. While both offenses pertain to unlawful marital contracts and are often conflated, they are distinct in their elements, legal basis, and requisite proof. The primary distinction lies in the existence of a prior valid marriage: bigamy requires it, while illegal marriage does not. This research will delineate the statutory framework, essential elements, jurisprudence, defenses, and procedural nuances of each crime to provide a clear legal demarcation.
II. Statutory Framework
The governing provisions are found in Title Eleven (Crimes Against Civil Status) of the Revised Penal Code.
Article 349. Bigamy.* “Any person who shall contract a second or subsequent marriage before the former marriage has been legally dissolved, or before the absent spouse has been declared presumptively dead by means of a judgment rendered in the proper proceedings, shall be guilty of bigamy.”
Article 350. Marriage contracted against provisions of laws. “The penalty of prision correccional* in its medium and maximum periods shall be imposed upon any person who, without being included in the provisions of the next preceding article, shall contract marriage knowing that the requirements of the law have not been complied with or that the marriage is in disregard of a legal impediment.”
III. Essential Elements of Bigamy (Article 349)
For a conviction of bigamy, the prosecution must prove the following elements beyond reasonable doubt:
IV. Essential Elements of Illegal Marriage (Article 350)
For a conviction of illegal marriage, the prosecution must prove:
a. The legal requirements for marriage (e.g., license, authority of solemnizing officer, consent) were not complied with; OR
b. A legal impediment (e.g., minority without parental consent, relationship within the prohibited degrees, psychological incapacity) existed at the time of the marriage ceremony.
V. Key Jurisprudential Doctrines on Bigamy
Good faith is not a defense. Mistaken belief that the first marriage was null and void is not a defense unless a judicial declaration of nullity was obtained prior to the second marriage (People v. Mendoza*, G.R. No. 128729, July 10, 2001).
Requirement of a valid first marriage. The first marriage must be proven to be valid and subsisting at the time of the second marriage. If the first marriage is void from the beginning (ab initio), such as one where a legal impediment existed, the crime is not bigamy but may be illegal marriage*.
Second marriage must be legally capacitated. If the second marriage is also void for reasons other than the existence of the first (e.g., lack of license), the crime may not be bigamy but could be illegal marriage*. The second marriage must be one that would have been valid had the first marriage not existed.
VI. Key Jurisprudential Doctrines on Illegal Marriage
Knowledge is crucial. The mens rea of the offense is the accused’s knowledge of the lack of legal requirements or the existence of a legal impediment* at the time of the marriage ceremony.
Applies to void and voidable marriages. The article applies to marriages that are either void or voidable under the Family Code*, provided the accused had knowledge of the defect.
Distinction from Bigamy. This is a catch-all provision for unlawful marriages not covered by Article 349. It is often invoked when a marriage is defective due to the absence of a marriage license, lack of authority of the solemnizing officer, or existence of a relative impediment* like minority.
VII. Comparative Analysis Table
| Element / Aspect | Bigamy (Article 349, RPC) | Illegal Marriage (Article 350, RPC) |
|---|---|---|
| Core Legal Object | Protecting the sanctity of a prior, valid, and subsisting marriage. | Ensuring compliance with the formal and essential requisites of marriage as prescribed by law. |
| Governing Provision | Article 349 of the Revised Penal Code. | Article 350 of the Revised Penal Code. |
| Prior Valid Marriage | Indispensable. Must be proven to be valid and undissolved. | Not required. The crime can be committed even in a first marriage. |
| Nature of Defect | The defect is the existence of a prior, subsisting marriage (impediment of prior marriage). | The defect is the lack of a legal requirement or the presence of a legal impediment other than a prior marriage (e.g., no license, minority, lack of authority). |
| Mens Rea (Criminal Intent) | Generally presumed from the act of contracting a second marriage. Intent to violate the law need not be proven. | Requires knowledge (scienter) that the legal requirements were not complied with or that a legal impediment existed. |
| Defense of Good Faith | Generally not a defense absent a prior judicial declaration of nullity or annulment. | Good faith or lack of knowledge of the defect is a complete defense, as it negates the required mens rea. |
| Relationship to Civil Nullity | A judicial declaration of nullity of the first marriage obtained after the second marriage does not absolve liability; it must be obtained before. | A subsequent judicial declaration that the marriage is void ab initio may impact the case, but the crime is consummated by the act of contracting it with knowledge of the defect. |
| Penalty | Prision mayor (6 years and 1 day to 12 years). | Prision correccional in its medium and maximum periods (2 years, 4 months and 1 day to 6 years). |
VIII. Defenses
Defenses Specific to Bigamy:*
The first marriage was void ab initio*.
The first spouse had been absent for the required period and there was a judicial declaration of presumptive death* prior to the subsequent marriage.
* The first marriage had been legally dissolved by annulment, declaration of nullity, or divorce (if obtained by the alien spouse) prior to the second marriage.
Defenses Specific to Illegal Marriage:*
Lack of knowledge (ignorantia facti) of the missing requirement or legal impediment*.
* Good faith belief in the validity of the marriage ceremony.
The alleged defect does not constitute a legal impediment or a missing essential requisite under the Family Code*.
IX. Procedural Considerations
Prescription. The crime prescribes in 15 years for bigamy (prision mayor) and 10 years for illegal marriage (prision correccional*), from the time of its commission.
Complaint.* Both crimes are generally not public crimes. A complaint by the offended spouse is often required for the institution of the criminal action, except in cases where both spouses are offenders.
Prejudice from the Civil Aspect. A final judgment of conviction in a bigamy case does not determine the civil status of the parties; a separate civil action* for declaration of nullity is required.
X. Conclusion
The crimes of bigamy and illegal marriage are fundamentally distinct. Bigamy under Article 349 is an offense against civil status predicated on the existence of a prior, valid, and subsisting marriage. Its essence is the violation of the exclusivity of the marital bond. In contrast, illegal marriage under Article 350 is an offense against the legal order governing the celebration of marriage itself, punishable due to the conscious disregard of formal or essential requisites. The critical points of divergence are the necessity of a prior valid marriage for bigamy and the requirement of knowledge of the defect for illegal marriage. Proper classification is imperative for accurate charging, presentation of evidence, and assertion of applicable defenses.
