Idaho Ancillary Probate

Ancillary probate handles out-of-state property for Idaho decedents. File in the county where property is located.

By Settled Editorial

Idaho handles most out-of-state estates with a $27 filing rather than a second probate case. Under Idaho Code 15-4-204, a domiciliary foreign personal representative may file authenticated copies of the appointment, and of any official bond given, with a court in the Idaho county where property belonging to the decedent is located, as long as no local administration and no application or petition for one is pending here. Idaho Code 15-4-205 then lets that representative exercise all powers of a local personal representative as to assets in Idaho.

Two kinds of families land on this page. One lives in another state and just learned the estate includes a cabin near McCall, farm ground in the Magic Valley, or a bank account in Coeur d'Alene. The other is settling an Idaho estate and found land in Oregon or Utah, which that state's court handles under its own rules. Idaho's half of both stories sits in Title 15, Chapter 4, "Foreign Personal Representatives, Ancillary Administration." If the decedent lived in Idaho, start with the domiciliary Idaho process instead. This page explains Idaho law in general rather than any one estate, so confirm your own facts with a licensed Idaho attorney or the clerk holding the file.

Why Idaho Has a Say at All

Land answers to the law of the place it sits. Idaho Code 15-1-301 makes the Idaho probate code apply to "the property of nonresidents located in this state," and to property coming into the control of a fiduciary subject to Idaho law. A court in Salt Lake City cannot move a deed recorded in Bonner County. That boundary is the whole reason ancillary administration exists.

What usually pulls a family into an Idaho filing:

  • Idaho real estate held in the decedent's sole name, from a Valley County cabin to irrigated ground in Canyon County
  • An Idaho bank or credit union account with no payable-on-death beneficiary
  • Tangible personal property sitting in an Idaho second home or storage unit
  • A debt someone in Idaho owes the decedent

Idaho Code 15-3-201(d) settles where the harder assets are located. A debt, other than one evidenced by investment or commercial paper, is located where the debtor resides, or at the principal office of a debtor that is not an individual. Commercial paper, investment paper, and other instruments are located where the instrument is. An interest in property held in trust is located where the trustee may be sued.

The Authenticated-Copy Filing, Step by Step

Here is the sequence when the home-state case is already open.

  1. Get appointed at the domicile first. Section 15-4-204 speaks to a domiciliary foreign personal representative, so the home-state appointment has to exist and stay in force.
  2. Order authenticated copies. The statute names two documents: the appointment, and any official bond the representative has given. Authenticated means the issuing court's certificate and seal, not a photocopy.
  3. Check the negative condition. The route is open only while no local administration, and no application or petition for one, is pending in Idaho.
  4. File in the right county. Section 15-4-204 says a court in this state in a county in which property belonging to the decedent is located. Look up which Idaho district court hears it before you mail anything.
  5. Pay the $27.00 fee. The Idaho Supreme Court's IRCP Appendix A fee schedule, effective July 12, 2024, lists "filing of copy of appointment of foreign personal representative" among the additional filings in probate at a total of $27.00.

Idaho publishes no statewide form for this filing. The court self-help site's forms index carries no decedent-estate forms at all, so ask the Clerk of the District Court in that county how it wants the packet assembled. The clerk is an elected county officer under Idaho Code 31-2001, and the same office also records deeds.

What the Filing Buys

Section 15-4-205 is one sentence long. A domiciliary foreign personal representative who has complied with 15-4-204 "may exercise as to assets in this state all powers of a local personal representative and may maintain actions and proceedings in this state subject to any conditions imposed upon nonresident parties generally."

Those local powers are broad. Idaho Code 15-3-711 gives a personal representative the same power over the title to estate property that an absolute owner would have, held in trust for creditors and others interested in the estate, and says the power "may be exercised without notice, hearing, or order of court." That is the authority a title company looks for behind a deed signed by an out-of-state executor.

One difference from some neighbors is worth knowing. Idaho's 15-4-205 carries no reciprocity condition for corporate fiduciaries. The section reads the same whether the home-state representative is a person or a bank's trust department.

What Ends Those Powers

Idaho Code 15-4-206 is the section families skip and later regret. It sets four rules:

  • The powers under 15-4-201 and 15-4-205 may be exercised only while no administration or application for one is pending in Idaho.
  • An application or petition for local administration terminates the foreign representative's power to act under 15-4-205. The local court may still allow limited powers to preserve the estate.
  • A person who changed position in reliance on the foreign representative's powers, before receiving actual notice of a pending local administration, is not prejudiced by it.
  • The local personal representative takes on the duties and obligations that accrued from the foreign representative's acts, and may be substituted in any Idaho action.

Filing also brings the representative within reach of Idaho courts. Idaho Code 15-4-301 says a foreign personal representative submits to Idaho jurisdiction by filing authenticated copies under 15-4-204, by collecting money or property under 15-4-201, or by doing any act in Idaho that would have given the state jurisdiction over that person as an individual. Jurisdiction from collecting under 15-4-201 is limited to the money or the value of the property collected. Idaho Code 15-4-303 allows service by registered or certified mail and gives the representative at least 30 days to appear or respond.

Collecting Idaho Personal Property With No Court Filing

Chapter 4 also carries a route that skips the courthouse. Idaho Code 15-4-201 says that at any time after 60 days from the death of a nonresident decedent, anyone who owes the estate, or holds its personal property or an instrument evidencing a debt, obligation, stock, or chose in action, may pay or deliver it to the domiciliary foreign personal representative. The holder needs proof of the appointment and an affidavit stating:

  • the date of death,
  • that no local administration, or application or petition for one, is pending in Idaho, and
  • that the representative is entitled to payment or delivery.

Idaho Code 15-4-202 is what persuades the bank: payment or delivery made in good faith on that proof releases the payer as if it had paid a local personal representative. Idaho Code 15-4-203 is the brake. Once a resident creditor has told the debtor or holder not to pay, the route closes. Idaho Code 15-4-101(c) defines a resident creditor as a person domiciled in, or doing business in, Idaho who is or could be a claimant against the nonresident's estate.

This route reaches personal property only. It cannot move a deed.

When a Full Idaho Case Is the Better Route

Open a local administration when nobody has been appointed at the domicile, when the will is contested, when a resident creditor has blocked the shortcut, or when a buyer or title insurer wants Idaho letters in the file. Idaho Code 15-4-207 says that for a nonresident decedent, Chapter 3 governs Idaho proceedings for probate of the will, appointment, removal, supervision, and discharge of the local personal representative, along with that representative's powers and duties and the rights of claimants and distributees.

Five Chapter 3 rules matter more to an out-of-state family than to anyone else.

Venue follows the property. Section 15-3-201(a)(2) puts the first proceeding for a decedent who was not domiciled in Idaho in any county where property of the decedent was located at the time of death. Later proceedings stay in that court under 15-3-201(b).

The application says so. Idaho Code 15-3-301(a)(3) requires a statement showing venue if the decedent was not domiciled in Idaho, and 15-3-301(b)(1) accepts a certified copy of a will probated in another jurisdiction in place of the original.

A will probated elsewhere gets an informal path. Idaho Code 15-3-303(d) allows informal probate of a will previously probated elsewhere "at any time" on written application by any interested person, with an authenticated copy of the will and of the statement probating it from the court where it was first probated. A will from a place that does not probate wills after death has its own route under 15-3-303(e) and, in a formal case, under Idaho Code 15-3-409, using an authenticated certificate from the will's legal custodian.

The home-state executor is first in line. Idaho Code 15-3-203(g) gives a personal representative appointed by a court of the decedent's domicile priority over all other persons, unless the will names different people for Idaho and the domicile, and lets that representative nominate someone with the same priority. Idaho Code 15-3-308(b) backs that up by denying an informal appointment to anyone else once a domicile court has appointed a representative whose appointment has not ended.

Everyone else waits 30 days. Idaho Code 15-3-307(a) makes the registrar wait at least 120 hours after any death before an informal appointment. For a nonresident, the registrar delays the order until 30 days have passed, unless the applicant is the personal representative appointed at the domicile or the will directs that the estate be subject to Idaho law.

A full local case costs $166.00. That is the total IRCP Appendix A sets for a "Petition for formal probate" or an "Application for informal probate" in Magistrate Division category A. From there the case runs like any other; our guide to Idaho probate walks the stages, and Idaho creditor claims covers the four-month notice.

The Three-Year Limit Has Two Carve-Outs

Idaho Code 15-3-108 bars most probate and appointment proceedings started more than three years after the death. Its opening sentence excludes two things that matter here: "a proceeding to probate a will previously probated at the testator's domicile," and appointment proceedings for an estate "in which there has been a prior appointment."

So a family that finds an Idaho parcel five years after a parent died in Washington is not automatically shut out, provided the Washington court probated the will. Section 15-3-303(d) points the same way by allowing that informal probate at any time. An intestate estate with no probated will gets no such carve-out, so move early when there is no will. The Idaho probate timeline collects the other clocks.

The Small Estate Affidavit Counts the Whole Estate

Families often try Idaho Code 15-3-1201 first and get surprised. The $100,000 ceiling is not the Idaho share. Subsection (a)(1) asks whether the fair market value of the entire estate subject to probate, "wherever located," less liens and encumbrances, exceeds $100,000. A paid-off house in the decedent's home state counts against that ceiling even though the affidavit collects only personal property.

Two more conditions trip multistate estates. Subsection (a)(3) closes the route if an application or petition for appointment of a personal representative, or for summary administration, is pending or has been granted "in any jurisdiction." Once the home-state court appoints an executor, the Idaho affidavit is off the table and 15-4-201 or 15-4-204 takes over. And Idaho has no affidavit for land, so a house or parcel in Idaho needs one of the routes above even when the estate is small. The Idaho small estate affidavit guide walks the route in full.

What the Idaho Piece Costs

Idaho prices this work in flat fees rather than a percentage of the estate, and Idaho has no estate or inheritance tax to add.

ItemAmountAuthority
Filing a copy of a foreign personal representative's appointment$27.00IRCP Appendix A, J.1.f
Opening a formal or informal probate$166.00IRCP Appendix A, Magistrate Division category A

Recording a deed of 30 pages or less$15.0031-3205(1)(b)(i)
Small estate affidavit$0, because it is never filed with a court15-3-1201

The other columns on Appendix A split each fee among state and county funds. The Total column is what you pay. Order extra certified copies of any Idaho letters early, since the county recorder, a title company, and a transfer agent may each want their own.

Closing the Idaho Piece

Two sections decide where Idaho assets go at the end. Idaho Code 15-3-816 says the estate of a nonresident administered by an Idaho-appointed representative goes to the domiciliary personal representative for the benefit of the successors, if that representative is willing to receive it. The exceptions are a will and choice-of-law rules that identify the successors under Idaho law, an Idaho representative who cannot find a domiciliary representative after reasonable inquiry, and a court order in a closing proceeding.

Idaho Code 15-3-815 handles the money side. Assets administered in Idaho answer to all claims, allowances, and charges established against the personal representative wherever appointed. When the estate falls short, each allowed claimant takes an equal proportion. When Idaho is not the last domicile and local assets cover the claims allowed here, the balance moves to the domiciliary representative.

If Idaho and another state disagree about where the decedent lived, Idaho Code 15-3-202 makes the Idaho court stay, dismiss, or amend its own proceeding unless the Idaho case started first. The domicile finding in the first-commenced proceeding controls. And under Idaho Code 15-4-401, a judgment for or against any personal representative of the estate, in any jurisdiction, binds the local representative as if it had been a party.

If the Decedent Lived in Idaho and Owned Land Elsewhere

Flip the roles and Idaho runs the main case. The Idaho district court appoints the personal representative, and the other state's court handles its own land under its own statutes and deadlines. Section 15-3-815 still applies on the Idaho side. Ask the Clerk of the District Court for several certified copies of the Idaho letters, because the other state's court will want an authenticated record. The Idaho executor duties guide covers the rest of the job.

Keeping Idaho Property Out of a Second Case

Most of this work is preventable while the owner is alive, but Idaho gives you fewer tools than many states.

Idaho has no transfer-on-death deed for real estate. Title 15, Chapter 6, "Nonprobate Transfers," covers accounts, securities, and community property with right of survivorship. It has no real-property transfer-on-death part. Do not rely on a TOD deed form written for another state.

Married couples can title land as community property with right of survivorship. Idaho Code 15-6-401 says that real property held by a husband and wife in that form transfers to the survivor on the first death. The deed has to "expressly declare" the estate. Our Idaho community property guide explains how this differs from ordinary community property.

Fund a trust with the deed itself. A revocable trust that already holds title to the Idaho parcel passes it without an Idaho court step, and one trust can hold land in several states. The deed has to be signed and recorded while the owner is alive. More options are in how to avoid probate in Idaho.

Frequently Asked Questions

Does Idaho always require a second probate case when a nonresident owned Idaho property?

No. Idaho Code 15-4-204 lets a domiciliary foreign personal representative file authenticated copies of the appointment, and of any official bond given, with a court in an Idaho county where property belonging to the decedent is located, as long as no local administration and no application or petition for one is pending in Idaho. Idaho Code 15-4-205 then gives that representative all powers of a local personal representative as to assets in Idaho, including the right to bring actions here. That is a filing, not a new probate case. A full Idaho administration is still the route when nobody has been appointed at the domicile, when someone contests the will, or when a title company insists on Idaho letters.

Which Idaho court handles ancillary probate?

The district court, heard in the magistrate division of the county where the Idaho property sits. Idaho Code 15-3-201(a)(2) puts venue for the first proceeding for a decedent who was not domiciled in Idaho in any county where property of the decedent was located at the time of death, and 15-4-204 uses the same county test for the authenticated-copy filing. Idaho Code 15-1-201(8) says the court with jurisdiction over decedents' estates is known in Idaho as the district court, and 1-2201 puts a magistrate division of it in every county. You file with the Clerk of the District Court.

What does ancillary probate cost in Idaho?

$27.00 to file the copy of a foreign personal representative's appointment. The Idaho Supreme Court's filing fee schedule (IRCP Appendix A, effective July 12, 2024) lists "filing of copy of appointment of foreign personal representative" under additional filings in probate at a total of $27.00. Opening a full Idaho probate instead costs $166.00, the total the same schedule sets for a petition for formal probate or an application for informal probate. Recording a deed with the county recorder costs $15.00 for an instrument of 30 pages or less under Idaho Code 31-3205(1)(b)(i).

How soon can an out-of-state executor be appointed in Idaho?

It depends on who applies. Idaho Code 15-3-307(a) makes the registrar wait at least 120 hours after the death before an informal appointment, and for a nonresident decedent it stretches the wait to 30 days after the death. The 30-day delay does not apply when the applicant is the personal representative appointed at the decedent's domicile, or when the will directs that the estate be subject to Idaho law. So the home-state executor can move sooner than anyone else.

Can an Idaho bank pay an out-of-state executor without any Idaho filing?

Yes, after 60 days, unless a local creditor objects. Idaho Code 15-4-201 lets a person who owes the nonresident's estate, or holds its personal property or stock, pay or deliver it to the domiciliary foreign personal representative on proof of appointment and an affidavit stating the date of death, that no local administration or application or petition for one is pending in Idaho, and that the representative is entitled to payment or delivery. Idaho Code 15-4-202 releases the payer to the same extent as payment to a local personal representative, and 15-4-203 blocks the payment once a resident creditor has told the holder not to pay.

Can an Idaho ancillary case start more than three years after the death?

Sometimes. Idaho Code 15-3-108 bars most probate and appointment proceedings more than three years after death, but it excludes a proceeding to probate a will previously probated at the testator's domicile, and appointment proceedings for an estate in which there has been a prior appointment. Idaho Code 15-3-303(d) adds that informal probate of a will previously probated elsewhere may be granted at any time on written application by an interested person, with an authenticated copy of the will and of the statement probating it.
