When a person dies intestate and the probate court is required to step in and name and administrator or personal representative to carry the estate through probate they must also provide the appointed person with letters of administration, sometimes called letters of testamentary. These are documents that show the person is appointed by the court and has the right and responsibility to handle financial, business, and other personal affairs on the deceased person's behalf. Banks, government agencies and other businesses require this proof before allowing the administrator access to the deceased person's accounts and personal information. These letters are intended to safeguard and prevent unauthorized people from accessing the deceased's information and possible removing assets without proper authority to do so.
