Is polyamory legal in the US?

Polyamory, which refers to consensually non-monogamous relationships involving more than two people, is not illegal in the United States. The Supreme Court has upheld the right to privacy in intimate relationships, which includes the right to engage in consensual sexual activity with multiple partners.

However, it is important to note that bigamy, or the act of marrying more than one person at the same time, is illegal in all 50 states. This means that individuals who are already married cannot legally enter into additional marriages, even if all parties involved consent to it.

Polyamorous relationships can also face legal issues related to custody and inheritance, as laws around these topics generally assume a monogamous model of family structure. For example, some states may not recognize the legal rights of multiple parents in polyamorous families, which could complicate custody and visitation arrangements.
