Childhood is the most important part of human life. A person's childhood decides what he will do in future. In this way, children are the future of the world. If the children have no family, then it comes to the state to provide equal care and affection to the children as family under the Juvenile Justice (Care and Protection of Children) Act, 2015. The present study is an attempt to find out the factors that lead to a child becoming homeless and coming to child care institutions. Further, the study analysed the rehabilitation measures undertaken by child care institutions to ensure maximum care of children. The study is based on doctrinal research, which used both primary and secondary sources of data and materials. Primary sources like court reports, Acts, government documents etc. have been used, and secondary sources like books, magazine articles, newspaper articles, magazines etc. have been used. The study suggested for active operation of the Juvenile Justice (Care and Protection of Children) Act, 2015 and Juvenile Justice Model Rules 2016.
