Michiie gave Tadaie KUJO, Norizane's son and Michiie's grandchild, to be the legitimate heir, a shobunjo (a kind of will) to give instructions that documents such as diaries (which were the most important heritage for a court noble at the time) should be inherited by the Ichijo Family, but that the head of a family who controls the family temples such as Tofuku-ji Temple should first be inherited by Sanetsune ICHIJO, the third son of Michiie, then by Tadaie KUJO, a child of the eldest son of Michiie, and later by either descendant of the Kujo Family or the Ichijo Family who took the highest-ranking official position (head of a clan).
そこで道家は嫡孫にあたる教実の子・九条忠家に対して処分状（遺言状みたいなもの）を渡し、当時の公家にとってもっとも重要な遺産であった日記などの文書類は一条家の相伝とするが、東福寺などの一族寺院の管理権を司る家長者は、まず最初は3男である一条実経が継ぎ、その次には長男の子九条忠家が継承して、以後は2人の子孫のうちでもっとも官職の高い人物（一門上首）が継ぐように指示を出した。
