It is an arrangement of living under which couples that is unmarried live together to conduct a relationship in the nature of marriage. Live-in-relationship is permissible only in unmarried major persons of heterogeneous sex.
According to the Supreme Court, living together by two adults with their consent and free will, is perfectly legal. The court has legalized it by way of its various judgments. We determine live-in relationship by finding out duration of relation, shared household and pooling of resources. For this, the couple in live-in relationship must hold themselves out to society as being akin to spouses; they must be of legal age to marry; they must be otherwise qualified to enter into a legal marriage, including being unmarried; and they must have voluntarily cohabited for a significant period of time.
