How to Find a Cause of Death in Montana (2026)

In Montana, you find a person's cause of death by ordering their death certificate, where the cause is recorded in the medical certification section. Montana is an open-record state, so any person may request a certified or informational copy for $16 with valid ID. The cause of death is not restricted from the public.

How Do You Find Someone's Cause of Death in Montana?

The most reliable way to find someone's cause of death in Montana is to order their death certificate. The cause of death is written on the certificate itself, in the section completed by the certifying physician, coroner, or medical examiner.

Because Montana is an open-record state, you do not have to be a relative to obtain that certificate. Under Montana Code Annotated 50-15-121, a certified or other copy of a death certificate must be issued upon the request of any person who applies, shows valid ID, and pays the fee.

You can also learn a cause of death through less formal sources. Published obituaries, funeral home notices, and local news coverage often describe how a person died, especially in accident or homicide cases.

For a death that was investigated, an autopsy report prepared by a coroner or the state Medical Examiner gives the most detailed medical findings.

Is the Cause of Death Public in Montana?

Yes. In Montana the cause of death is public because the death certificate that carries it is available to any requester. Montana does not place the cause of death behind a separate confidentiality rule for the general public.

This follows from the state's open death-record statute. MCA 50-15-121(4) directs that a death certificate be issued "upon request of any person," and the cause of death is part of that certificate.

Montana does not impose a multi-decade waiting period before death records, or the cause of death on them, become public. That is different from states that release a death certificate to family only, or that redact the cause of death for many years.

Where the Cause of Death Is Recorded

The cause of death lives in two main places in Montana: the death certificate and, when one is performed, the autopsy report. They serve different purposes.

The Death Certificate

The death certificate is the official legal record of the death. Its medical certification section lists the immediate cause of death, any underlying conditions that led to it, and the manner of death, such as natural, accident, suicide, homicide, or undetermined.

For a death under medical care, the attending physician usually certifies the cause. For an unattended, sudden, violent, or suspicious death, a county coroner certifies it, sometimes listing the cause as "pending" until tests are complete.

The Autopsy Report

When a death is investigated, an autopsy report provides far more medical detail than the certificate. In Montana, autopsies for coroners and law enforcement are performed by forensic pathologists at the Montana Medical Examiner's Office, a bureau of the Department of Justice Forensic Science Division.

These reports, which usually include toxicology results, are returned to the requesting county coroner and are typically completed within 60 to 90 days. Access to a full autopsy report is narrower than access to the certificate and is often tied to the investigation or the next of kin.

How to Request Records That Show the Cause of Death

To get the cause of death, request the death certificate from the Montana Office of Vital Records within the Department of Public Health and Human Services (DPHHS). The cause of death is printed on the certified and informational copies it issues.

You can request a Montana death certificate in several ways:

• By mail to Montana Vital Records, PO Box 4210, Helena, MT 59604, with a completed application, a photocopy of your ID or a notarized application, and a check or money order.
• In person at any Montana County Clerk and Recorder's office with a valid photo ID.
• Online or by phone through the state's authorized vendor with a credit or debit card.

Each copy costs $16 as of 2026, and the fee is non-refundable. You will need a valid photo ID, or accepted alternatives such as a notarized application or multiple signed documents.

For an autopsy report, contact the county coroner for the county where the death occurred, since final reports are returned to the coroner for distribution.

Finding the Cause of Death for Older or Historical Deaths

For older Montana deaths, the same death certificate is still the primary record, and because Montana is an open-record state you can usually order a copy without proving kinship. The Office of Vital Records holds the statewide records, and county clerks hold local copies.

For genealogy and historical research, the cause of death may also appear in archived newspaper obituaries, cemetery records, and church or funeral home registers. These can fill gaps when an older certificate is hard to locate or hard to read.

The Social Security Death Index is a useful starting point for deaths going back decades. It confirms the fact and date of death and a last residence, but it does not record the cause of death, so it points you toward the certificate rather than replacing it.
