Student did have a runway excursion; student was taxing at a safe speed and the plane kept veering right. I tried to help and apply left rudder and brake and the plane would not stop as if the right brake was stuck. The plane rolled off the taxiway. No damage to airport property; personnel; or aircraft. Plane was inspected by maintenance and we then continued our flight without further incident. The location was at ZZZ on a taxiway heading east to Runway XX.
An instructor pilot reported the aircraft's right brake stuck while taxiing resulting in a runway excursion. No damage to airport; aircraft or people.
