bigamy

Picture someone promising "till death do us part" to one partner and then secretly entering a second marriage while the first union is still valid. That is the core idea. It isn't about casual promiscuity; it is the legal act of marrying another person before the first marriage is ended. In many legal systems, this is treated as a serious offense linked to deception and breach of trust. Polygamy can describe broader multi-spouse customs, while this word usually points to one extra legal marriage that violates a single-spouse rule.

Bigamy is the act of entering into a new marriage while still legally married to another person. It is more than infidelity; it is a legal offense that requires a second official marriage bond or ceremony while the first marriage remains valid. Historically, people sometimes hid this by moving to a new city or country and starting over, but modern cases are more often uncovered through records, finances, and witness testimony.

The legal context is key: simply living with multiple partners or having an affair is not bigamy. The offense requires a formal second marriage before divorce or annulment ends the first. In places that enforce monogamous marriage law, bigamy is punishable by courts through fines or imprisonment. You also see it in court reports, legal dramas, or true-crime stories. For example: "The detective uncovered evidence of bigamy when the suspect's two wives both came forward," or "He was arrested for bigamy after his second spouse discovered his first marriage had never been legally dissolved."
