The Montana Affidavit of Death (PDF) is a legal document that is used when a death occurs in Montana. It is a sworn statement that is used to establish the facts of the deceased's death. This document is typically used by family members, next of kin, or other individuals with knowledge of the circumstances of the death. The affidavit includes the full name of the deceased, date of birth, place of death, date of death, and other relevant information. It is signed by an individual with personal knowledge of the death and witnessed by two other individuals. There are two different types of Montana Affidavit of Death (PDF): the Declaration of Death and the Certificate of Death. The Declaration of Death is used when the deceased has not been seen or heard from in five years or more. It requires a sworn statement by two individuals with personal knowledge of the death. The Certificate of Death is used when the death occurred within the last five years and requires the signature of a physician, coroner, or other medical professional attesting to the cause of death.
