Second Relationship After Conversion to Islam While Still Married: Bigamy and Marriage Validity Issues

In the Philippines, the legal landscape governing marriage is a complex duality: the Family Code, which governs civil and Christian marriages, and Presidential Decree No. 1083 (The Code of Muslim Personal Laws), which governs marriages between Muslims.

A recurring legal dilemma arises when a person, originally married under Civil Law, converts to Islam and subsequently enters into a second marriage without legally dissolving the first. This scenario sits at the heart of a conflict between religious freedom and the state’s interest in protecting the "inviolable social institution" of marriage.


1. The Core Conflict: Article 349 vs. Religious Privilege

Under the Revised Penal Code (Article 349), bigamy is committed by 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.

However, many converts believe that their conversion to Islam grants them the immediate right to practice polygyny (taking up to four wives) as permitted by Shari’ah. The Philippine Supreme Court has repeatedly clarified that conversion to Islam is not a "get-out-of-jail-free" card for bigamy.


2. The Validity of the Second Marriage

For a second marriage after conversion to be recognized as valid and non-bigamous, specific criteria must be met:

  • The Nature of the First Marriage: If the first marriage was celebrated under the Family Code (civil or Christian rites), it remains valid and subsisting regardless of the husband's conversion.
  • The Applicability of PD 1083: The Code of Muslim Personal Laws applies only if both parties are Muslim at the time of the marriage, or if the male party is Muslim and the marriage is solemnized under Muslim law.
  • Prior Marriage Dissolution: Crucially, if the first marriage was a civil marriage to a non-Muslim, the convert cannot simply ignore it. The first marriage must be dissolved through legal means (e.g., annulment or declaration of nullity) before the second marriage can be considered valid under the eyes of the State.

3. Jurisprudence: The "Nolasco" and "Sarabia" Precedents

The Supreme Court has established clear boundaries in cases such as Nolasco vs. Philippines and Sarabia vs. Justice Secretary:

  1. Non-Retroactivity of Conversion: Conversion to Islam does not retroactively apply the provisions of PD 1083 to a prior civil marriage.
  2. Criminal Liability: A party who converts to Islam and marries a second wife while the first civil marriage is still intact can still be prosecuted for Bigamy. The Court views the act of entering into a second marriage without a judicial declaration of nullity of the first as the "actus reus" of the crime.
  3. Good Faith Defense: Claiming that one followed the tenets of Islam is generally not a valid defense against a charge of bigamy if the first marriage was governed by the Family Code.

4. Comparison of Legal Frameworks

Feature Civil/Family Code Muslim Code (PD 1083)
Number of Spouses Monogamy strictly enforced. Polygyny permitted (up to four).
Dissolution Annulment/Nullity (No Divorce). Talaq (Divorce) is recognized.
Bigamy Risk High; subsequent marriage is void. Permitted if Shari'ah requirements are met.
Requirement for 2nd Wife Not applicable (Illegal). Notice to Shari’ah Court and first wife.

5. Practical Implications and Risks

Entering into a second relationship after conversion while still civilly married leads to several legal complications:

  • Voidness of the Second Marriage: Under the Family Code, the second marriage is void ab initio (void from the beginning) for being bigamous.
  • Property Relations: Since the second marriage is void, no "conjugal partnership" exists. Property relations will likely be governed by Article 148 of the Family Code (co-ownership based on actual contribution).
  • Legitimacy of Children: Children born of the second, bigamous marriage are considered illegitimate under Civil Law, affecting their successional rights (inheritance).
  • Imprisonment: Bigamy carries a penalty of prision mayor (6 to 12 years of imprisonment).

6. The "Proper" Legal Path

For a convert wishing to marry again under Muslim law without violating Philippine Civil Law, the following steps are generally required:

  1. Legal Severance: Obtain a judicial decree of annulment or nullity of the first civil marriage in a Regional Trial Court (RTC).
  2. Registration: Ensure the conversion and the dissolution of the prior marriage are properly recorded in the Civil Registry.
  3. Compliance with Shari'ah: Follow the requirements of PD 1083, including providing notice to the Clerk of the Shari'ah Circuit Court where the family resides.

Note: While Shari'ah courts have jurisdiction over Muslim personal law, they do not have the authority to dissolve a marriage celebrated under the Civil Code or the Family Code.
