Morris & Others, Executors v. McMillin & Others, Administrators was a case heard by the United States Supreme Court in 1884. The case involved a dispute between the executors of a will and the administrators of an estate. The executors argued that the administrators had wrongfully taken possession of the estate and had failed to pay the executors the money they were due. The Supreme Court ruled in favor of the executors, finding that the administrators had acted improperly and had failed to pay the executors the money they were due. The Court also held that the executors were entitled to damages for the wrongful taking of the estate. The Court's decision established that executors have a right to be paid for their services and that administrators must act in good faith when dealing with executors.

In Morris & Others, Executors v. McMillin & Others, Administrators, the Supreme Court was asked to decide whether a state court had jurisdiction over an estate dispute between citizens of different states. The majority opinion held that the state court did not have jurisdiction and reversed the judgment of the lower courts. Justice Field dissented from this decision on two grounds: firstly, he argued that it was within Congress’s power to confer such jurisdiction upon a state court; secondly, he argued that even if Congress had not done so in this case there were still sufficient facts present for federal diversity jurisdiction to apply under Article III of the Constitution. He concluded by stating his belief that “the action should be remanded with directions to proceed according to law."
