When a person dies owning only a modest amount of property, Idaho law offers shortcuts that can avoid a full probate. The best known is the small estate affidavit, a sworn written statement that lets a successor collect the decedent’s personal property without a personal representative being appointed (Idaho Code § 15-3-1201). A “successor” is a person, other than a creditor, who is entitled to property of the decedent under the will or Idaho’s Uniform Probate Code (Idaho Code §§ 15-1-101, 15-1-201(50)).

This page explains when the affidavit can be used, what it must say, what protection it gives the people who hand over property, and two related summary procedures: a quick closing for very small estates that are administered, and a special procedure when a surviving spouse is the only heir or devisee.

When the Small Estate Affidavit Can Be Used

The affidavit may be used starting 30 days after the decedent’s death (Idaho Code § 15-3-1201(a)). It may be made by or on behalf of the successor (§ 15-3-1201(a)). The affidavit must state all of the following (§ 15-3-1201(a)(1)-(4)):

1. The fair market value of the entire estate of the decedent that is subject to probate, wherever located, less liens and encumbrances, does not exceed $100,000 (§ 15-3-1201(a)(1)).
2. Thirty (30) days have passed since the death (§ 15-3-1201(a)(2)).
3. No application or petition for appointment of a personal representative or for summary administration is pending or has been granted in any jurisdiction (§ 15-3-1201(a)(3)).
4. The claiming successor is entitled to payment or delivery of the property, including entitlement as a trust under the decedent’s will (§ 15-3-1201(a)(4)).

Note that the $100,000 limit counts the decedent’s probate estate “wherever located,” not just property in Idaho, and it is measured after subtracting liens and encumbrances (Idaho Code § 15-3-1201(a)(1)). Property that passes outside probate is discussed in Nonprobate Transfers in Idaho.

What Property Can Be Collected

Section 15-3-1201 is titled “Collection of personal property by affidavit.” Once presented with a proper affidavit, the following persons must pay or deliver to the successor (Idaho Code § 15-3-1201(a)):

• Anyone who owes a debt to the decedent, who must make payment (§ 15-3-1201(a)).
• Anyone holding the decedent’s tangible personal property (§ 15-3-1201(a)).
• Anyone holding an instrument evidencing a debt, obligation, stock, or chose in action belonging to the decedent (§ 15-3-1201(a)).

A transfer agent of any security must change the registered ownership on the corporation’s books from the decedent to the successor or successors when presented with the affidavit (Idaho Code § 15-3-1201(b)).

No Court Order or Will Probate Needed

Ordinarily a will must be declared valid by informal probate or a court order before it can prove a transfer of property, but the Idaho Code makes an exception for § 15-3-1201 (Idaho Code § 15-3-102). The three-year time limit that applies to most probate and appointment proceedings also does not apply to proceedings under § 15-3-1201 or § 15-3-1205 (Idaho Code § 15-3-108).

Effect of the Affidavit

A person who pays, delivers, transfers, or issues property under the affidavit is discharged and released to the same extent as if dealing with a personal representative (Idaho Code § 15-3-1202). That person does not have to see how the property is used or look into whether the affidavit’s statements are true (§ 15-3-1202).

If someone who receives the affidavit refuses to pay or deliver, the property may be recovered, or its delivery compelled, in a proceeding brought by or for the persons entitled to it, upon proof of their right (Idaho Code § 15-3-1202).

The person who receives property under the affidavit is answerable and accountable for it to any personal representative of the estate or to anyone else with a superior right (Idaho Code § 15-3-1202). When there is no administration, successors also take subject to charges such as creditors’ claims and the allowances of the surviving spouse and dependent children (Idaho Code § 15-3-901). For more on creditors, see Creditor Claims Against an Idaho Estate.

Recovery of Medical Assistance by the Department of Health and Welfare

For the recovery of medical assistance, the Idaho Department of Health and Welfare is treated as a successor that may use the affidavit, if it follows certain steps (Idaho Code § 15-3-1201(c)). Before presenting the affidavit, the department must send notice by regular mail to anyone it knows to be an heir, successor, or creditor of the estate, and certify that notice in writing to the person who owes the debt or holds the property (§ 15-3-1201(c)(1)).

Within 60 days of the mailing, anyone claiming reimbursement for priority estate expenses permitted by § 15-3-805(a)(1) through (4) may send the department a written demand with documentation (Idaho Code § 15-3-1201(c)(2)). After receiving the funds, and up to the amount received, the department must pay priority claims it determines would be allowed in a probate proceeding and notify each claimant of the result (§ 15-3-1201(c)(2)).

Summary Administration for Very Small Estates

A separate shortcut applies when a personal representative has been appointed but the estate is very small. If the inventory and appraisal show that the estate, less liens and encumbrances, does not exceed the total of the items below, the personal representative may immediately disburse and distribute the estate to those entitled, without giving notice to creditors (Idaho Code § 15-3-1203):

• Homestead allowance (§ 15-3-1203).
• Exempt property (§ 15-3-1203).
• Costs and expenses of administration (§ 15-3-1203).
• Reasonable funeral expenses (§ 15-3-1203).
• Reasonable and necessary medical and hospital expenses of the last illness (§ 15-3-1203).

The homestead allowance and exempt property are explained in Spouse and Children Protections in Idaho.

Closing a Small Estate by Sworn Statement

Unless a court order prohibits it, and except for estates in supervised administration, the personal representative may close an estate handled this way by filing a verified statement at any time after disbursement and distribution (Idaho Code § 15-3-1204(a)). The statement must say that (§ 15-3-1204(a)(1)-(3)):

• To the best of the personal representative’s knowledge, the estate did not exceed the total of the items listed above (§ 15-3-1204(a)(1)).
• The personal representative has fully administered the estate by disbursing and distributing it to those entitled (§ 15-3-1204(a)(2)).
• The personal representative sent a copy of the closing statement to all distributees and to all known creditors or claimants whose claims are neither paid nor barred, and gave a full written account to the distributees whose interests are affected (§ 15-3-1204(a)(3)).

If no actions or proceedings involving the personal representative are pending one year after the closing statement is filed, the appointment ends (Idaho Code § 15-3-1204(b)). The statement has the same effect as a closing statement under § 15-3-1003 (§ 15-3-1204(c)). Regular closings are covered in Closing an Estate in Idaho.

When a Surviving Spouse Is the Sole Heir or Devisee

If a person dies, with or without a will, leaving a surviving spouse as the sole devisee or beneficiary, the surviving spouse (or a person claiming title through the spouse) may file a verified petition setting out the marriage and the death (Idaho Code § 15-3-1205(a)). If there was a will, the original must accompany the petition, and notice of hearing is given under § 15-1-401 (§ 15-3-1205(a)).

If it appears at the hearing that the two were duly married and the surviving spouse is the sole heir or devisee, the court makes a decree to that effect, which has the same effect as a formal decree approving or determining distribution (Idaho Code § 15-3-1205(b)). The petitioner and the surviving spouse need not appear in person, nor must the petitioner’s attorney (§ 15-3-1205(b)). Instead, the petitioner or attorney may appear by telephone on the petitioner’s proper motion, or submit affidavits before the hearing certifying that notice was given and no objection was received (§ 15-3-1205(b)(1)-(2)).

A spouse who uses this procedure assumes and is liable for all debts that might be a claim against the decedent’s estate, and there is no administration of the estate (Idaho Code § 15-3-1205(c)).

Comparing the Options

Procedure	Who uses it	Key limit or condition
Small estate affidavit	A successor, or someone on the successor’s behalf (Idaho Code § 15-3-1201(a))	Probate estate of $100,000 or less after liens and encumbrances; at least 30 days after death; no personal representative or summary administration pending or granted (§ 15-3-1201(a))
Summary administration	An appointed personal representative (§ 15-3-1203)	Estate does not exceed homestead allowance, exempt property, administration costs, reasonable funeral expenses, and last-illness medical and hospital expenses (§ 15-3-1203)
Surviving spouse petition	A surviving spouse who is the sole devisee or heir, or a person claiming through the spouse (§ 15-3-1205(a))	Court hearing with notice; spouse becomes liable for the decedent’s debts that might be claims (§ 15-3-1205)

If none of these fits, the estate may need informal or formal probate. See Informal vs. Formal Probate in Idaho.

How I Can Help

I can help you figure out whether an estate qualifies for the small estate affidavit or one of Idaho’s other summary procedures, prepare the affidavit or petition, and deal with banks, transfer agents, or others who are reluctant to release property. If the estate turns out to need a probate case, I can guide you through that as well. Request a consultation to discuss your situation.
