Little people, big lawsuit.

The Roloff family, who found fame on TLC series Little People, Big World, seem to be drama-free onscreen.

But parents Amy and Matt secretly sued Oregon's Washington County and two if its employees after the mother of four allegedly endured a terrifying encounter with a building services inspector that she claims turned physical.

According to Amy, inspector John Wheeler snuck onto the family's Hillsboro, Oregon, farm on July 16, 2010, despite no trespassing signs and a call box to request permission from the couple.
