In 1355, to prevent the spread of the hanzei law, the feudal government exempted provinces in which the disturbance had settled from its application and made the Honjo (lord of the manor) pay half of the customs or taxes to the provincial constable, instead of letting the provincial constable directly collect the customs or taxes from peasants even in the provinces in which the disturbance was still continuing.
1355年（文和4年/正平10年）、幕府は半済の拡大を防ぐため、戦乱の収まった国の半済を停止するとともに、戦乱国においても、守護が年貢半分を直接徴収するのではなく、本所（荘園領主）から守護へ納入させることとした。
