What Are the Burial and Cremation Laws in Idaho?

Idaho has no statutory minimum waiting period before cremation. A medical examiner or coroner must authorize the cremation before it proceeds. Written consent of the person authorized to control disposition (IC 54-1120), plus additional written authorization from the county coroner in the county where death occurred (IC 39-268(3); IDAPA 24.08.01, Rule 100.06.d.ii, eff. 7-1-25).

No. Natural organic reduction (human composting) is not currently authorized in Idaho.

Yes. Alkaline hydrolysis (water cremation) is legal in Idaho.

Idaho sets a statutory order for who controls the disposition of remains (IC 54-1142): Person designated in a written instrument acknowledged like a real property conveyance, OR person designated on military DD Form 93 (both at same priority level — IC 54-1142(a)), then Agent under durable power of attorney for health care (unless explicitly denied), then Agent under durable power of attorney (if it explicitly grants disposition authority), and so on. You can also name your own agent to control your remains in a signed, written document before death. You can record those wishes alongside the rest of your estate plan when you create a revocable living trust.

No. Idaho does not require embalming by law. Embalming is not required by state law. However, if a body is held longer than 24 hours before burial, cremation, or other disposition, it must be either embalmed or refrigerated at 36 degrees Fahrenheit or less (IDAPA 24.08.01, Rule 100.06.d.iii).

Idaho law does not require a licensed funeral director to direct disposition. IC 39-268 expressly contemplates a "mortician or person acting as such" assuming first possession of the body and filing the written report (within 24 hours of taking possession) that serves as the in-state burial/transit permit, so a family member acting in that role may file the report and obtain the permit. The death certificate itself is medically certified by the attending physician, physician assistant, or APRN (IC 39-260) — not by a funeral director. Title 54, Chapter 11 licenses funeral practitioners but does not bar a family from transporting and burying or cremating its own dead. Cremation still requires written authorization from the county coroner in the county where death occurred (IDAPA 24.08.01, Rule 100.06.d.ii) regardless of who directs the disposition. Local zoning and county health rules may impose practical constraints on family-directed home burial.

Idaho provides a publicly funded option when a family cannot pay for disposition: County board of commissioners indigent burial or cremation (Idaho Code 31-3412). Eligible veterans may also be interred at no cost through the U.S. Department of Veterans Affairs. Indigent disposition is a county responsibility, not a single statewide program. Under IC 31-3412 the county board of commissioners must provide for burial or cremation of any deceased indigent person, capped at the rate established or negotiated by that county board. Application is made to the board, typically by the coroner, mortician, or other responsible party who cannot locate next of kin or obtain a waiver of intent to abandon; a coroner may authorize cremation ten days after death once an application is filed. Separately, under IC 31-2802, if no one takes charge of the body within fourteen days the coroner must arrange decent interment or cremation, with insufficient-estate costs charged to the county per IC 31-3412. Veterans: federal VA burial and memorial benefits are available, and Idaho operates two state veterans cemeteries (Boise and Blackfoot) through the Idaho Division of Veterans Services; the VA pays interment fees for eligible veterans, while preparation and associated funeral expenses fall to the family or estate. Confirm county-specific application procedures with the relevant county clerk or coroner.
