What term describes a person appointed to administer the estate of one who died without a will?

The term that best describes a person appointed to administer the estate of someone who died without a will is "Administrator." When a person passes away intestate, meaning without a will, the court appoints an administrator to manage the deceased's affairs, including settling debts, distributing assets, and ensuring that all legal matters related to the estate are handled appropriately. This role is crucial because the administrator acts in the best interests of both the estate and its heirs, following state laws governing intestate succession.

The other terms listed have different meanings in the context of estate management. An executor is someone designated in a will to manage the estate of a deceased person who has passed away with a will. A beneficiary is an individual who receives an inheritance or benefits from a will or trust. A trustee is appointed to manage a trust and is responsible for managing the assets held within that trust according to the terms set forth by the trust document.
