A void subsequent marriage does not require dissolution by divorce; however, bigamous marriages not yet adjudicated as void remain effective, thereby entitling such spouses to inherit alongside legitimate heirs under the Civil and Commercial Code.
1) Formal Legal Style
“Where a subsequent registration of marriage is void ab initio for lack of legal necessity, no divorce is required to terminate such void act; however, in cases of bigamous marriages not yet adjudicated as void by the court, such marriages remain legally effective, and the spouses thereto are entitled to inherit as statutory heirs alongside legitimate descendants pursuant to the Civil and Commercial Code.”
2) Litigation / Courtroom Style
“A void second marriage registration produces no legal effect and does not necessitate dissolution by divorce; nevertheless, marriages entered into in contravention of monogamy, though voidable, remain valid and enforceable until judicially annulled, thereby conferring upon such spouses the status of lawful heirs with rights of succession equal to those provided under the Civil and Commercial Code.”
3) Academic / Analytical Style
“The legal consequence of a void marriage differs fundamentally from that of a voidable bigamous marriage: while the former is ineffective without the need for formal dissolution, the latter retains legal force until annulled by judicial decree, thus preserving the inheritance rights of the spouse under statutory succession rules.”
