Can a 16-year-old get emancipated and live with a boyfriend?

Very few states allow the emancipation of minors. Those states that do have grounds and procedures rarely grant emancipation rights to a minor for reasons other than to allow the minor to be adopted or be placed in state custody to receive public assistance. There is no court in any state with emancipation status that would allow a minor to become emancipated for the purpose of cohabitation.
