Small Estate Affidavit Thresholds & Procedure in Idaho

At a glance

Requirements one by one

Governing law

Idaho Code § 15-3-1201, "Collection of personal property by affidavit," paired with § 15-3-1202, "Effect of affidavit" — both part of Idaho's adoption of the Uniform Probate Code, Title 15, Chapter 3, Part 12.

Dollar threshold

$100,000, testing "the fair market value of the entire estate of the decedent which is subject to probate, wherever located, less liens and encumbrances." The figure isn't adjusted for inflation. No bill changing it was found pending in the current legislative session.

Court filing required?

No. The affidavit goes directly to whoever holds the decedent's property — a bank, an employer, a securities transfer agent — with no filing and no judge's order needed. The statute even builds this in as a qualifying condition: using the affidavit requires that no petition for either a personal representative OR summary administration is already pending or granted.

Waiting period after death

30 days.

Works with a will, intestacy, or both?

Both. The statute covers any "claiming successor," and its own text confirms this includes someone "entitled to payment or delivery of the property, including entitlement as a trust pursuant to a will of the decedent" — alongside the ordinary intestate-heir case.

Does it cover real property?

No. The affidavit's operative clause only reaches "tangible personal property or an instrument evidencing a debt, obligation, stock or chose in action" — nothing in this Part transfers real estate. The Uniform Probate Code's own official comment, carried into Idaho's annotated code, explains the reasoning directly: "Since the appointment of a personal representative may be obtained easily under the Code, it is unnecessary to make the provisions regarding small estates applicable to realty." A house or land needs full or summary probate — or, if the decedent is survived only by a spouse who is the sole beneficiary, a separate summary-administration decree under § 15-3-1205, a distinct spousal-only procedure rather than a bigger version of this affidavit.

Signature formalities

The statute itself doesn't spell out a signing ceremony beyond a sworn affidavit. Ada County's official Court Assistance Office form has the affiant swear to the statement and sign it before a notary public. It doesn't include witness signature lines.

Protection for the bank/holder

Solid, and it covers both sides. A holder who pays, delivers, or transfers property under a valid affidavit "is discharged and released to the same extent as if he dealt with a personal representative," with no duty to check whether the affidavit's statements are true. If a holder wrongly refuses to honor a valid affidavit, the successor can force the issue in court. The person who actually collects the property, though, carries real exposure of their own — they're "answerable and accountable ... to any personal representative of the estate or to any other person having a superior right," an open-ended obligation with no fixed dollar cap in the statute's own text.

What trips people up

The biggest one: real property is completely off the table for this affidavit no matter how small the estate otherwise is — a house or land always needs a different process. A second trap: people sometimes confuse Idaho's spouse-only summary administration (§ 15-3-1205) with a "real estate version" of the small estate affidavit — it isn't; it's a separate court proceeding limited to cases where the surviving spouse is the sole heir or will beneficiary, with no fixed dollar cap of its own. A third: the $100,000 figure tests only the part of the estate that is "subject to probate," wherever that property is located, after liens and encumbrances are subtracted.

Common questions

Do I have to wait before using the affidavit? Yes — 30 days must pass after the death first.

Can I use this affidavit for my father's house? No — the affidavit never reaches real property, regardless of value. If your only surviving parent's spouse is the sole heir, a separate summary-administration court process may apply instead.

My mother didn't leave a will. Can I still use the affidavit? Yes — it works the same way whether the decedent left a will or died intestate, as long as you qualify as a successor either way.

Does the affidavit need to be notarized? The statute calls for an affidavit but doesn't specify the signing ceremony. Ada County's official form requires the affiant to swear and sign before a notary public.
