Cremation rules in Wyoming
How long you have to wait, who is allowed to sign the authorization, and what slows it down.

Why there's a wait, and who has to sign
Cremation is permanent, so states build in two safeguards: a minimum waiting period after death, and a rule about who is allowed to sign the authorization. The wait gives the medical examiner or coroner time to decide whether the death needs investigation. The authorization rule follows a fixed order of relatives, which matters when family members disagree or when the closest relative cannot be reached. A direct disposer or crematory cannot proceed without the right signature.
The rules in Wyoming
| Minimum wait before cremation | 24 hours after death |
|---|---|
| Who can authorize | Authorizing agent per state statutory priority list (usually surviving spouse, then adult children, then other heirs) |
| Statute | Wyo. Stat. §35-12-101 |
If the medical examiner or coroner is involved
Sudden, unexpected, or unattended deaths are usually reported to the medical examiner or coroner, and the body cannot be released for cremation until that office signs off. This can add days. Ask the office directly for the expected release date rather than waiting to hear; they will tell you.
