To find out someone’s cause of death, the authoritative source is the long-form death certificate, issued by the vital records office in the state where the person died. If you’re a close relative, a legal representative, or someone with a recognized interest in the record, you can order a certified copy that includes the full cause-of-death information. If you don’t qualify, obituaries, news reports, and genealogy databases can fill in some of the picture, and older records eventually open to the public.
Order the Long-Form Death Certificate
States issue two versions of the death certificate. The short form (sometimes called an informational copy) confirms that the person died but leaves out medical details. The long form, or certified copy, carries the cause of death. If you want to know what someone died of, the long form is what you need to request.
Death certificates are maintained by the vital records office in the state where the death occurred, and most states let you order online, by mail, or in person. County health departments often handle recent deaths and can be faster. To complete the application, you’ll need the deceased’s full legal name, the date of death, and the location where the death occurred.1USAGov. How to Get a Certified Copy of a Death Certificate The form will ask your relationship to the deceased and your reason for the request, and most states require a copy of your photo ID along with documentation proving the relationship you’re claiming.
Fees for a certified copy generally run $15 to $25, with higher charges for expedited processing or additional copies. Mail orders typically take two to four weeks; in-person requests can be done in a few business days. Online third-party vendors are sometimes faster but add a service fee on top of the state charge.
Who Qualifies
States restrict certified death certificates, especially the long form, to people with a recognized relationship or need. The categories are broadly similar from state to state:
- Immediate family — a surviving spouse, children, parents, and siblings can almost always obtain a certified copy with proof of the relationship (your own birth certificate, marriage certificate, or similar).1USAGov. How to Get a Certified Copy of a Death Certificate
- Legal representatives — an attorney, estate executor, or personal representative named in a court order can request the certificate on behalf of the estate or a family member.
- Others with a direct interest — some states extend eligibility to beneficiaries named in a will or life insurance policy, funeral directors, or others who can show a specific legal or financial need tied to the death.
- Government agencies — federal and state agencies can access death records for law enforcement, benefits administration, and other official purposes.
If you fall outside these categories and the death is recent, the vital records office is unlikely to release a certified copy with the cause of death. Your path then shifts to the alternatives further down.
What the Cause-of-Death Section Shows
The cause-of-death section is more detailed than most people expect. It isn’t one line. The certifying physician or medical examiner records a chain: the immediate cause on the first line, then each underlying condition that led to the next, working back to the root cause. A death from a heart attack caused by coronary artery disease caused by long-standing diabetes would list all three in sequence. A separate section captures other conditions that contributed but weren’t in the direct chain. The certificate also records the manner of death — natural, accident, suicide, homicide, or “could not be determined.”2Centers for Disease Control and Prevention. U.S. Standard Certificate of Death
When the Cause Reads “Pending”
If you order the certificate soon after the death and the cause reads “pending” or “pending further investigation,” the case is still under review. This happens more often than families expect, and it doesn’t by itself suggest anything suspicious.
A pending designation usually means the medical examiner or coroner couldn’t determine the cause from the initial investigation alone. Toxicology results generally take three to four weeks, longer when confirmation testing is needed. Histology, the microscopic examination of tissue, can take up to six weeks. When both are involved, the full investigation can run several months.
Once the investigation closes, the certifier finalizes the cause and manner of death and the certificate is amended. If you’ve already received a preliminary copy, you’ll need to order an updated one to see the final cause. In rare cases the manner of death stays “undetermined” because the evidence doesn’t support a definitive conclusion, though the case may be reopened if new information surfaces.
If You Can’t Get the Certificate
When you don’t meet the eligibility rules, several other sources can give you something, though none carry the authority of the certified record.
Obituaries and News Reports
Obituaries sometimes name the cause of death, though families aren’t obligated to and many choose phrases like “died after a long illness” or “died suddenly.” When a death involves unusual circumstances — accidents, homicides, or public figures — news outlets often report the cause independently and sometimes quote the medical examiner directly. Newspaper archives and online obituary databases are searchable for free or at low cost.
Genealogy Databases
For older deaths, platforms like Ancestry.com and FamilySearch host digitized death records, including historical death certificates showing cause of death. These are most useful for deaths that occurred decades ago, before modern privacy restrictions applied. FamilySearch is free; Ancestry requires a subscription for most records. Whether cause-of-death information is included depends on when and where the death occurred and whether the original certificate has been digitized.
The Social Security Death Master File
The Social Security Administration’s Death Master File records deaths reported to the agency. It confirms that a death occurred but does not include the cause of death.3Social Security Administration. Requesting SSA’s Death Information It’s useful mainly for confirming the date and location of a death so you can approach the right vital records office.
One boundary worth knowing: the CDC’s WONDER database and the National Death Index hold mortality data drawn from death certificates, but WONDER is for statistical queries about populations, not individual lookups, and the National Death Index is restricted to approved researchers with Institutional Review Board approval and cannot be used for personal, genealogical, or legal purposes.4Centers for Disease Control and Prevention.

Older Deaths That Have Become Public
Most states eventually release death certificates to the general public after a set period, and once that period expires anyone can request a copy regardless of their relationship to the deceased.1USAGov. How to Get a Certified Copy of a Death Certificate The waiting period varies: some states release records after 25 years, others hold them for 50, 75, or even 100 years, and not every state has sunset provisions at all. If you’re researching someone who died decades ago, check with the vital records office in the state where the death happened. For deaths far enough back, state archives and genealogy databases often have digitized copies that are freely searchable.
Autopsy and Medical Examiner Reports
The death certificate records the conclusion; the autopsy report tells the full story. A full autopsy involves external and internal examination of the body along with microscopic tissue analysis and laboratory testing, and the resulting report can run dozens of pages with findings that never appear on the certificate itself.5Centers for Disease Control and Prevention. Coroner and Medical Examiner Laws
Access rules depend heavily on the state. In some, autopsy reports from government medical examiners and coroners are public records and anyone can request a copy. In others, access is limited to next of kin, legal representatives, or parties with a court order. Even where reports are technically public, a court can seal portions if release would interfere with an active criminal investigation.
Not every death produces an autopsy. Medical examiners and coroners typically investigate deaths that are sudden, unexpected, violent, unattended, or otherwise suspicious. Deaths in hospitals from known medical conditions usually don’t trigger an investigation, and in those cases the only cause-of-death record will be whatever the attending physician wrote on the certificate. Families can commission private autopsies, but those results belong to whoever ordered them.
If You Think the Cause of Death Is Wrong
You can request a correction, but the process is tightly controlled. In most states, changes to the medical certification — the cause and manner of death — can only be initiated by the physician or medical examiner who originally signed the certificate. You can’t just tell the vital records office what you think the cause should be.
The usual path is to contact the original certifier, present whatever evidence supports a different conclusion, and have them submit a corrected certification to the state vital records office. If the certifier disagrees or is unavailable, your options may include petitioning the state medical examiner’s office or seeking a court order. The amendment fee typically runs $15 to $40 depending on the state, and you’ll need to order a new certified copy to replace the old one. Family members and legal next of kin are generally the ones who can start the process, though an attorney or estate representative can act on their behalf.
