Per Medieval Law, if a land Tenant died and left no Heirs to take possession of his property or belongings, they were to fall under control of The Lord (or even King). This “gap” was called the “Escheat”. Specially appointed Clerks called “Escheators”, were sent out to assess any properties and determine if their “worth” was in the interest of their Liege. This title would eventually evolve into the term “Exchequer”.
