In the "Buke myomoku-sho" (Compilation of Historical Data of the Warrior Class), it is written (under the entries for the titles of offices of the first volume): "Monchujo is a government body different from Mandokoro (Administrative Board) but makes political decisions together and functions as a court of justice."
なお、『武家名目抄』には「問注所は政所の別庁にて、ともに政事を沙汰する中にも、訴訟の裁判を本務とする所なり」（職名部（ハ）上）と記されている。
