Quick answer: Opening an estate in Idaho costs a district court filing fee that commonly runs $80–$200, varying by county. The small estate affidavit needs no court filing at all. Publication and bond are extra. See the full picture in the Idaho probate cost calculator.

Confirm the exact fee with your county District Court clerk, since it varies by county.
Other administration costs
- Publication to creditors — newspaper notice for three weeks, opening a 4-month claim window from first publication (~$100–$200).
- Bond — may be required unless waived by the will or heirs.
- Appraisal — if real estate or a business must be valued.
- Personal representative & attorney fees — the real variables, both reasonable amounts under §§ 15-3-719 and 15-3-715(21).
Not the big cost: the district court filing fee is small next to the personal representative and attorney fees. Idaho has no estate or inheritance tax, so there's no death-tax layer.
Ways to keep court costs down
- Small estate affidavit — personal property up to $100,000, net of liens, no filing fee at all (Idaho Code § 15-3-1201).
- Summary administration — for a surviving spouse as sole beneficiary (§ 15-3-1205).
- Informal probate — registrar-handled, no hearing, no extra court cost over the filing fee.
