The way the current generation in India views their relationships has changed dramatically. With society loosening up about pre-marital sex and live-in relationships, the stigma that once surrounded couples in live-in relationships has begun to dissipate.
A live-in relationship not only allows the pair to get to know each other without committing to a legally binding relationship, but it also eliminates the upheaval of family drama and lengthy court proceedings if the pair decides to split up. It entails the partners living together indefinitely without any responsibilities or duties to one another. There is no law binding them together, and as a result, either partner can end the relationship whenever they wish. 
Most Western countries have a larger view of the concept of a couple in a relationship, as seen by the legal recognition of prenuptial agreements, civil and domestic unions of couples, and other similar practices. In India, however, things are different.
In numerous decisions, the Supreme Court has stated that if a man and a woman “lived like husband and wife” in a long-term relationship and even had children, the courts would assume that they were married and that the same laws would apply. In another case, the Supreme Court decided that a man and a woman living together in love is a part of their right to life, not a “criminal offense.” As a result, in India, live-in relationships are legal. 
No law binds the partners together, and as a result, either partner can walk out of the relationship whenever they want. Because there is no legal definition of a live-in relationship, the legal status of such relationships is similarly unknown. The court decides on the right to maintenance in a live-in relationship based on the Domestic Violence Act and the facts of the case.
Though the average person is still unwilling to accept such a partnership, the Protection of Women from Domestic Violence Act provides for the protection and support of an aggrieved live-in partner, as well as the right to alimony.
