Indian law is a result of an evolution, which includes personal laws for peaceful practice of social custom, culture and religious norm. But some time these social custom, culture and religious norms have contradictions with fundamental rights, directive principles and legitimacy. Hindu personal law is a branch of it. My research article is based on conflicts between Hindu personal law, Indian constitution, and societal law understanding and practice. I study how and why these are conflicting. Because for the ground applicability of fundamental rights it is necessary that personal laws follows to them. But a law must have ‘Social acceptance’. Here we find that ‘Social acceptance’ Play an important role in building of legitimacy for any law and constitutional fundamental rights in social grassroots level. And it is difficult to think that without abolish this disconnection the practice and opportunity to consume fundamental rights would be increase.
