The manuscript represents the land titles and genealogy of the descendants of Don Miguel Irecha ("king") Cuar (also spelled Quara) . It was probably made to document claims of heredity rights or possession of lands within the context of some litigation. It includes six pages of Tarascan and Spanish text. On one of the plates is the following inscription: "...Dios trin y uno que tien el poder padre hijo señor desta trira" (God, three and one, the power, father and son, the holy spirit, amen. Titles of the ancient lords of this land).
