Whether New York could adjudicate the rights of nonresident beneficiaries in a common-trust-fund accounting without personally serving them.
Holding
Yes. New York had authority to settle the accounts of a trust created and administered under its law, including as to nonresident beneficiaries, so long as the proceeding afforded constitutionally adequate notice and an opportunity to be heard.
Reasoning
The Court declined to make the State's power turn on the uncertain historical distinction between in rem and in personam proceedings. Labels were especially unhelpful for a trust accounting, which had features of both types of action but fit neither category neatly.
New York had a substantial and traditional interest in supervising fiduciaries operating under its laws and in bringing trust administration to a final conclusion. That interest permitted its courts to determine the claims of resident and nonresident beneficiaries alike, provided the procedure gave affected persons a meaningful chance to appear and object.
