The name of “Udalguri”, according to legend, owes its origin to the fact that there were large numbers of “Odal” trees in this part of the region.
The District Judiciary, Udalguri came into existence on 29th September,2011. Since then the Courts of the District Judge as well as that of the Chief Judicial Magistrate, Udalguri is running from the existing judicial building meant for the establishment of Sub-divisional Judicial Magistrate, Udalguri. There is no independent or separate building for accommodating the court of the District Judge and the Chief Judicial Magistrate and hence, the present arrangement continues.
The court of the Sub-Divisional Judicial Magistrate, Udalguri came into existence in 1986. At that time this judicial court was being run from the office building of the Deputy Commissioner, Udalguri. Feeling the need for a separate judicial building, a new building was constructed to accommodate the courts of Sub-Divisional Judicial Magistrate, Munsiff cum Magistrate and Judicial Magistrate First Class. But in the mean time the Govt. of Assam, vide order dated 31.3.2007 created the establishment of District and Sessions Judge, Udalguri as well as establishment of Chief Judicial Magistrate, Udalguri. Originally, Udalguri was under the judgeship of Darrang District with headquarter at Mangaldai.
Be that as it may, the District Judiciary Udalguri comprises of nine sanctioned posts which are- District & Sessions Judge, Additional District & Sessions Judge, Civil Judge (Sr. Divn.) & Asstt. Sessions Judge, Civil Judge (Jr. Divn.), Chief Judicial Magistrate, Addl. Chief Judicial Magistrate, Sub-Divisional Judicial Magistrate (S), Judicial Magistrate (1st Class), Judicial Magistrate (2nd Class).
