What this office does

County judge (county executive). In Texas and a few other states the county judge is the county's chief executive and presides over the commissioners court, the county's governing board. The office prepares the budget, runs county administration and emergency management and, in smaller counties, still hears some probate and misdemeanor matters. It is an administrative office more than a courtroom one.
