A Sub-Divisional Magistrate (SDM) is a government official in charge of a sub-division, which is a smaller administrative region within a district. The SDM plays a crucial role in maintaining law and order, overseeing local governance, and implementing government policies. They have the authority to conduct inquiries, issue orders, and manage various administrative tasks. In addition to law enforcement, the SDM is responsible for revenue collection and managing land records. They often work closely with other officials, such as the District Collector and Tehsildar, to ensure effective administration and address the needs of the local population.
