Void Marriage as a Defense to Bigamy

News hook: On August 17, 2026 the Supreme Court's Third Division, in a decision penned by Associate Justice Alfredo Benjamin S. Caguioa, acquitted Ma. Fe Imelda Lapira of bigamy, reversing the Regional Trial Court of Pampanga and the Court of Appeals. Both lower courts had convicted her on the theory that she remained criminally liable because her first marriage had never been judicially declared void before she married again. The Supreme Court held that a marriage void from the beginning may be raised as a defense to bigamy even without a prior court declaration.

Legal question

If your first marriage was void from the very start — no license, no ceremony, or another fatal defect — and you marry again, can you still be convicted of bigamy for not having secured a declaration of nullity first?

Applicable laws and rules

Revised Penal Code, Article 349 — bigamy: contracting a second or subsequent marriage before the former marriage has been legally dissolved, or before the absent spouse has been declared presumptively dead
Family Code, Article 2 — essential requisites of marriage: legal capacity of the contracting parties, and consent freely given in the presence of the solemnizing officer
Family Code, Article 3 — formal requisites: authority of the solemnizing officer, a valid marriage license (except in cases of marriages exempt from the requirement), and a marriage ceremony
Family Code, Article 4 — the absence of any essential or formal requisite renders the marriage void ab initio
Family Code, Article 35 — marriages void from the beginning, including those solemnized without a license except in exempt cases
Family Code, Article 40 — the absolute nullity of a previous marriage may be invoked for purposes of remarriage only on the basis of a final judgment declaring it void
Rules of Court, Rule 132, Section 28 — proof of the lack of a record, by certification of the custodian
Rules of Court, Rule 131 — burden of proof and presumptions; the prosecution must prove every element beyond reasonable doubt

Why this matters

Bigamy prosecutions in the Philippines are almost never about polygamy in any organized sense. They arise when a person whose first marriage was defective, abandoned, or fictional marries again years later — and someone, often an estranged relative or a party to a property dispute, files a complaint.

For decades those prosecutions ran on a formalist rule: whatever the first marriage's defects, you had to obtain a judicial declaration of nullity before remarrying, and failing to do so made you guilty regardless. That rule turned a paperwork omission into a criminal conviction carrying imprisonment.

The Supreme Court has now applied its corrected position in a concrete acquittal. For anyone in the Philippines whose first marriage never legally existed — and there are many, given how often licenses were never issued and ceremonies never held — this is the difference between a criminal record and none.

What happened in the case

Ma. Fe Imelda Lapira was charged with bigamy under Article 349 of the Revised Penal Code for marrying Jimmy Fariscal while still married to Takahiko Sato, a Japanese national. The first marriage was evidenced by a marriage certificate from the Office of the Civil Registrar General.

At trial Lapira argued the Sato marriage was void because no ceremony took place and no marriage license was issued — both required for validity. The Local Civil Registrar confirmed there was no record of any application for a marriage license for Lapira and Sato.

Both the RTC of Pampanga and the Court of Appeals convicted her anyway, holding that she remained criminally liable because the first marriage had not been judicially declared void before the second was contracted. The Supreme Court's Third Division disagreed and acquitted.

The reasoning: a missing element, not a missing document

The Court applied its ruling in Pulido v. People, which held that an accused in a bigamy case may directly argue that a previous marriage is void as a defense, without a prior court declaration. The logic is structural rather than technical.

One of the essential elements of bigamy is the existence of a valid prior marriage. If the first marriage was void from the beginning, that element is simply absent — there was never a subsisting marriage to be bigamous against. A criminal conviction cannot rest on an element the prosecution has not proved, and the accused is entitled to contest any element of the offense charged.

On the evidence, the Court held that the certification from the Local Civil Registrar that no marriage license was issued to Lapira and Sato sufficiently proved the absence of a license, and that this certification was enough to counter the presumption of validity arising from the marriage certificate. Because the prosecution offered no additional evidence confirming the validity of the first marriage, there was reasonable doubt as to an essential element — and reasonable doubt requires acquittal.

Reconciling this with Article 40 of the Family Code

The obvious objection is Article 40 of the Family Code, which provides that the absolute nullity of a previous marriage may be invoked for purposes of remarriage only on the basis of a final judgment declaring it void. Does the acquittal read Article 40 out of the law?

No, and the distinction matters. Article 40 governs the civil consequences: whether your second marriage is itself valid, and the status, property relations, and legitimacy questions that follow from it. Bigamy is a criminal charge, where the State must prove every element beyond reasonable doubt and the accused may put any element in issue. The two operate on different registers.

The practical consequence is uncomfortable but must be stated clearly. An acquittal of bigamy on the ground that the first marriage was void does not automatically validate the second marriage. The second marriage may still be void for want of compliance with Article 40, and a separate petition for declaration of nullity of the first marriage remains the way to fix status, succession, and property questions. Escaping criminal liability and having a valid marriage are not the same thing.

When is a marriage void from the beginning

Article 4 of the Family Code states the rule: the absence of any essential or formal requisite renders a marriage void ab initio. The requisites are:

Essential (Article 2): legal capacity of the contracting parties, who must be a male and a female; and consent freely given in the presence of the solemnizing officer.
Formal (Article 3): authority of the solemnizing officer; a valid marriage license, except in the marriages exempt from the requirement; and a marriage ceremony in which the parties personally declare before the solemnizing officer and at least two witnesses of legal age that they take each other as husband and wife.

Article 35 lists the marriages void from the beginning, including those contracted by a party below eighteen even with parental consent, those solemnized by a person without legal authority (subject to the good faith exception), those solemnized without a license except in exempt cases, bigamous or polygamous marriages not falling under Article 41, those contracted through mistake of identity, and certain subsequent marriages void under Article 53.

Note carefully what is not on that list. Psychological incapacity under Article 36, and marriages voidable under Article 45 — lack of parental consent for those aged 18 to 21, unsound mind, fraud, force, impotence, serious sexually transmissible disease — are on a different footing. A voidable marriage is valid until annulled, so it cannot support this defense at all. And while Article 36 nullity is a species of void marriage, proving psychological incapacity as a defense inside a criminal trial is a far heavier task than producing a registrar's certification that no license was issued.

Proving it: the registrar's certification

The evidentiary point in this case is as useful as the doctrine. A certification from the Local Civil Registrar that no record of a marriage license application exists was held sufficient to overcome the presumption of validity carried by the marriage certificate. This is the mechanism under Rule 132, Section 28 of the Rules of Court, which allows proof of the lack of a record by a written statement from the custodian that a diligent search disclosed no such record.

In practice, that means the certification must come from the civil registrar of the city or municipality that would have issued the license, must reflect a diligent search, and should be accompanied by evidence identifying the correct place and period searched. A certification for the wrong municipality proves nothing. Once produced, the burden effectively shifts back to the prosecution to establish the validity of the first marriage with something more than the certificate.

What individuals should know

If you are facing a bigamy charge and your first marriage was defective from the outset, do not assume you must lose because you never obtained a declaration of nullity. Raise the nullity as a defense in the criminal case and build the record: a certification from the Local Civil Registrar that no license was issued, evidence that no ceremony was held, evidence that the solemnizing officer lacked authority, or whatever the specific defect is. The absence of a valid first marriage negates an element of the crime.

If you are planning to remarry and believe your first marriage is void, file the petition for declaration of absolute nullity anyway. It is the only route to a clean civil status — for the validity of your next marriage, for the legitimacy and surname of children, for the property regime, and for succession. The Lapira acquittal is a shield in a criminal case, not a substitute for the petition.

If you are considering filing a bigamy complaint, understand that the case now requires you to prove that the first marriage was valid, not merely that a marriage certificate exists. A certificate creates a presumption, and a registrar's certification of no license can defeat it. Bigamy is also a public offense — it is prosecuted by the State, not settled between the parties — and the prescriptive period runs from discovery, which is itself frequently litigated.
