Idaho: Small Estate Affidavit Thresholds & Procedure

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. Every official county form — and the template Idaho Legal Aid
Services makes available to low-income residents — has the affiant swear
to the statement and sign it before a notary public. No witness
signatures are required.

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 only counts what's actually "subject to
probate" — assets that pass automatically at death, like joint-tenancy
property or accounts with a payable-on-death beneficiary, don't count
toward the limit at all.

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? Yes, in practice — while
the bare statute doesn't specify a signing ceremony, every official
county form requires the affiant's signature to be made and acknowledged
before a notary public.
