From the standpoint of the Kamakura bakufu, however, wayo to others could lead territories of shogunal retainers to be scattered and lost as well as cause a problem that if the fief given to shogunal retainers who had a master-servant relationship with the bakufu as onkyu (rewards from a master to a vassal) was subject to wayo to a third party who was not in the master-servant relationship, the bakufu could not claim back the onkyuchi (land awarded by the lord) in compensation for the breach of obligations, as such third party was not obliged to "serve" in exchange for the "favor."
だが、鎌倉幕府から見れば他人和与は御家人領の散逸のみならず、幕府と主従関係にある御家人にあたえた恩給知行が、主従関係にない第三者に和与された場合、第三者には「御恩」に対する「奉公」の義務が無く、義務違反による恩給地の取り戻し（収公）が不可能になるという問題も生じる可能性があった。
