It was stipulated, however, that 寮司 could not send "I" (移) directly to other sho or officials of other sho; instead, 寮司 had to send ge (an official document) in advance to the sho which the receiver belonged to, asking for permission to send "I" (移), and then the sho which 寮司 belonged to sent "I" (移) to the sho which the receiver belonged to.
なお、寮司が他省及びその被管の官司に移を送付する場合には、直接相手先に送付できず、予め所管の省に移を送付する旨の解(公文書)を送付して許可を得た後に所管の省から相手先の所管の省に送付する規定となっていた。
