In 2016, Mr. Praveen Kumar initiated socio-legal aid services in Bihar under the Criminal Justice Fellowship Program of the Tata Institute of Social Sciences, Mumbai. In the course of his fellowship, he intervened in several prisons and addressed issues of socio-legal aid. After a sustained endeavor of three years of extending socio-legal aid services to the custodial population lodged in various jails in Bihar, he met Santosh Kumar and Shubhendu Shekhar during his fellowship journey. They all encountered several issues pertaining to the disadvantaged custodial population. Thus, they registered LAW Foundation as a trust in 2019 whose core work revolves around the areas of socio-legal aid services, networking, training, research, and documentation, besides advocacy of custodial, institutional, legal, and constitutional rights of the custodial population. It is also focused on the rehabilitation and re-integration of socioeconomically marginalized and vulnerable individuals and groups.
