I think accepting live-in relationships would bring more complications in the society. It basically means having the conjugal relationship but evading the responsibility attached to it through marriage. Of course, the system of marriage, in its present form, is in jeopoardy, mainly due to prohibitive costs involved. Even after spending lakhs of rupees, you just cannot be sure about fate of the marriage. A number girls in our surroundings have remained unmarried on this account.
Instead of giving sanction to live-in relationships, we must bring some reforms in the marriage system itself. Some reforms have been suggested by Delhi Gurdwara Prabhandak Committee for the Sikh community to reduce the costs. These can be adopted by other communities also. Some improvements are are required in divorce laws so that it does not take years to move out of a failed marriage and to tie a new bond.
