The institutions of marriage and the family are important social institutions that provide for the security, support and companionship of members of our society and bear an important role in the rearing of children. The celebration of a marriage gives rise to moral and legal obligations, particularly the reciprocal duty of support placed upon spouses and their joint responsibility for supporting and raising children born of the marriage. These legal obligations perform an important social function. Live-in relationships are not new to our society. The only difference is that now people are wide open to it. The basic idea of live-in relationships originates from Western and European countries. People coming from different parts share accommodation, develops intimacy gradually and in the long run decide to stay together with each other. Many countries have passed the law for example China, Australia, Denmark, Sweden, Scotland, United States and France. In India Female Live-in partners have economic rights under protection of women from Domestic Violence Act, 2005 (PWDVA). Live-in relationship is a very sensitive issue. The endless scope for differences in human attitudes and activities means that there will be an almost infinite variety of combinations of circumstances which may fall for consideration. In any particular case, it will be a question of fact and degree, a jury question, whether a relationship between two unrelated persons of the opposite sex meets the statutory test.
