Which item must be filed with the state after the disposition of a body?

The requirement to file a certificate of disposition with the state after the disposition of a body is essential because it serves as an official record confirming how and where the body was handled after death. This document provides vital information such as the name of the deceased, the date and location of the disposition, and the method used (burial, cremation, etc.).

Filing this certificate helps maintain accurate public records and ensures compliance with state regulations governing the handling of deceased individuals. It is crucial for legal and administrative purposes, as it supports the documentation needed for death certificates and the settlement of the deceased's estate.

While a funeral service plan outlines the arrangements made for the funeral, and a cremation authorization form is specific to the agreement for cremation, neither of these documents fulfills the legal requirement of notifying the state about the final disposition. A death notice is typically published for public awareness but does not serve as an official record with the state. Therefore, the correct answer is the certificate of disposition, as it is specifically mandated for filing following a body’s final disposition.
