This paper analyses the legal and policy framework in creating an enabling environment for prevention of child marriage. The paper asserts that an enabling legal and policy environment can contribute in turning child marriage practice into a less viable option for parents and girls. It illustrates that legal framework with respect to restraining child marriage in Bangladesh suffers from ambiguity. It neither allows nor disallows child marriage. Ambiguity and conflicting position on crimializing and invalidating child marriage by the legal framework is the major obstacle in the enforcement of legislative instruments for restraining child marriage in Bangladesh. Contemporary social policies on issue of child marriage reflect lack of shared aims and vision in comprehending and approaching the problem. Few policies have explicitly brought the issue of child marriage as an impediment to social and economic development. However, in general there has been implicit recognition of the issue. The strategies set out in the social policies while focus on many of the risk and protective factors for child marriage they lack cohesiveness, connectedness and vigor. The issue has not been thematically mainstreamed into the entire social sector. Appropriate framework for elimination of child marriage requires greater synergy and harmonization between and among social policies and five year plans. Laws, policies, and programmes for elimination of child marriage should be woven around poverty, vulnerability, discrimination, abuse, violence, and dowry. Child marriage restraining programs needs to involve multiple sectors and follow multiple approaches.
