The present invention relates to a control method for a laundry treatment apparatus. The method comprises a water supply step for supplying water to a first accommodating part, conducting the first washing step in the accommodating part and driving at least one of a stirring part and a second accommodating part to rotate. The first washing step in the accommodating part comprises a first action for rotating the stirring part so as to form a water flow; a second action for rotating the second accommodating part so as to drive the water to flow into the second accommodating part through a second input port when the water rises in a space between the inner peripheral surface of the first accommodating part and the outer peripheral surface of the second accommodating part.
