Before you begin — know the assets and liabilities
Before you file in Jefferson County, list the assets, debts, account holders, real estate, vehicle titles and beneficiary designations. Venue turns on the decedent's domicile, so confirm that Jefferson County is the right county before starting an estate settlement filing (Idaho Code § 15-3-201).
Sunset's estate settlement process includes asset discovery across more than 2,300 financial institutions, which can help you decide whether a Jefferson County filing is needed before you prepare an application or petition.
Which court handles jurisdiction
Idaho has no separate court for decedents' estates: probate is a case class assigned to the magistrate division of the district court, which sits in every one of Idaho's 44 counties, and a magistrate judge hears it (Idaho Const. art. V, § 20; Idaho Code § 1-2201, § 1-2208). The papers are filed with the clerk of the district court at the Jefferson County Courthouse.
Jefferson County is in Idaho's Seventh Judicial District with Bingham, Bonneville, Butte, Clark, Custer, Fremont, Lemhi, Madison and Teton Counties (Idaho Code § 1-808). The judicial district organizes judges, local rules and district administration, but a Jefferson County estate is filed at the Jefferson County Courthouse in Rigby when venue is proper there under Idaho Code § 15-3-201.
Rigby is the courthouse city and county seat. For the first informal or formal proceeding, Idaho venue is in the county where the decedent was domiciled at death, or, for a decedent not domiciled in Idaho, in a county where the decedent's property was located (Idaho Code § 15-3-201).
The jurisdiction process
- Confirm venue. File in Jefferson County if the decedent was domiciled there, or if the decedent was not domiciled in Idaho but had property in Jefferson County (Idaho Code § 15-3-201).
- Choose the filing path. An informal probate filing uses an application, and the registrar, meaning a magistrate judge or district judge, makes the required findings and may issue a written statement of informal probate after the statutory waiting period (Idaho Code § 15-1-307; Idaho Code § 15-3-301; Idaho Code § 15-3-302). A formal probate filing uses a petition and proceeds before a judge with notice (Idaho Code § 15-1-201; Idaho Code § 15-3-401; Idaho Code § 15-3-402).
- Prepare the application or petition and any will. If there is an original will and the case is e-filed, I.R.E.F.S. Rule 5(a) requires the original will to be filed conventionally within seven business days.
- File with the clerk of the district court at the Jefferson County Courthouse, 210 Courthouse Way, Suite 120, Rigby, ID 83442. Attorneys file electronically; a self-represented individual may choose File and Serve or paper filing under the Idaho Rules for Electronic Filing and Service Rule 4.
- Pay the opening filing fee. The Idaho Supreme Court Appendix A filing schedule effective July 12, 2024 lists $166.00 for a petition for formal probate or an application for informal probate in the magistrate division, with statutory components including Idaho Code § 31-3201A, § 1-2003, § 73-213 and § 31-3201.
- Handle notice and any hearing. Informal probate is handled by the registrar under Idaho Code § 15-3-302. Formal proceedings involve notice and a judge (Idaho Code § 15-1-201; Idaho Code § 15-3-401). For any requested appearance by telephone or video teleconference, ask the clerk how the judge applies Idaho R. Civ. P. 7.2.
- Obtain authority. After appointment, qualification and issuance of letters, the personal representative can administer the estate (Idaho Code § 15-3-103). Idaho's statutory letters include letters testamentary and letters of administration (Idaho Code § 15-1-201).
- Administer and close. The personal representative gathers assets, addresses claims, keeps records, prepares an inventory within three months after appointment, sends it to interested persons who request it, and may file it with the court (Idaho Code § 15-3-706). Idaho lets a personal representative publish notice to creditors to start the four-month claims bar, with mailed or delivered notice handled under the statute's 60-day rule (Idaho Code § 15-3-801).
Forms and documents
Probate forms in Jefferson County
Start with the Idaho Court Assistance Office forms library at courtselfhelp.idaho.gov/Forms, then call the Jefferson County clerk's office before filing to ask whether a local cover sheet or formatting practice applies. The Jefferson County materials reviewed for this page did not publish a separate county probate packet.
For an informal proceeding, Idaho uses an application; for a formal proceeding, Idaho uses a petition (Idaho Code § 15-3-301; Idaho Code § 15-3-402). If a will is involved and the case is e-filed, I.R.E.F.S. Rule 5(a) requires the original will to be filed conventionally within seven business days.
Local nuance
Jefferson County-specific considerations
Jefferson County's own directory separates court-related contact from the Clerk's Office line used for recorded documents. Because Idaho's clerk of the district court is also the county's auditor and recorder (Idaho Code § 31-2001), that split matters: call the Courts line, (208) 745-6313, option 3, for court questions, and use the published clerk numbers if you need the clerk's office directly.
Jefferson County residents use the Seventh Judicial District Court Assistance Office rather than a separate walk-in office in Rigby. The office is based at 605 N. Capital Avenue, Idaho Falls, ID 83402, and the Court Assistance Office page for Jefferson County lists 208-589-9872 as the phone and text line, with hours from 8:00 a.m. to noon and 1:00 p.m. to 5:00 p.m., Monday through Friday, excluding holidays. The Court Assistance Office provides forms information, document review and legal information through courtselfhelp.idaho.gov, but it does not represent you.
Jefferson County also has one of the Seventh Judicial District's statutory district-judge resident chambers (Idaho Code § 1-808). That does not identify where the magistrate judge for a particular estate matter sits, and it does not change where a Jefferson County probate filing is made.

Scenarios
| Situation | Likely Jefferson County path | Where Sunset helps |
|---|---|---|
| Surviving spouse w/ co-owned home | Confirm title, beneficiary designations and whether a court filing is needed. If the surviving spouse is the sole beneficiary, ask an attorney about the summary administration route, including the debt-liability rule and telephone-appearance option (Idaho Code § 15-3-1205). | Sunset helps identify accounts, organize title information and connect the family with a probate attorney when the home or spouse-only route needs legal review. |
| Out-of-state adult child w/ small estate | If only personal property is involved, review Idaho's collection of personal property by affidavit route after 30 days, which applies when the probate estate is within the statutory amount and no application, petition or summary administration is pending or granted (Idaho Code § 15-3-1201). If a Jefferson County filing is needed, call the clerk about paper filing or File and Serve. | Sunset helps find accounts, separate probate and nonprobate assets, and generate an organized packet for filing or attorney review. |
| Parent settling predeceased child's estate, home must be sold | A home generally points toward a Jefferson County probate filing if venue is proper there. The personal representative will need authority through letters before estate administration steps such as sale, transfer or closing (Idaho Code § 15-3-103; Idaho Code § 15-1-201). | Sunset helps inventory assets and debts, prepare filing information and connect the parent with a local probate attorney for sale and title issues. |

When to hire an attorney
Consider a probate attorney when the estate includes real property, creditor issues, family disagreement, a business, tax questions, an out-of-state decedent, or uncertainty about informal probate, formal probate or summary administration (Idaho Code § 15-3-302; Idaho Code § 15-3-401; Idaho Code § 15-3-1205).

Frequently asked questions
Where do I file probate for a Jefferson County resident?
File with the clerk of the district court at the Jefferson County Courthouse in Rigby if Jefferson County is the proper venue. Idaho venue for the first informal or formal proceeding is based on the decedent's domicile, or, for a decedent not domiciled in Idaho, a county where the decedent's property was located (Idaho Code § 15-3-201).
Which phone number should I use for Jefferson County probate questions?
The Idaho courts directory lists (208) 745-7736 as Jefferson County's main phone. Jefferson County's own site lists (208) 745-7756 for the Clerk's Office and (208) 745-6313, option 3, for Courts. If one number does not connect, try the others.
Can I e-file a Jefferson County probate case?
Idaho courts use iCourt File and Serve. Attorneys file electronically under the Idaho Rules for Electronic Filing and Service Rule 4(a). A self-represented individual may choose File and Serve or paper filing under I.R.E.F.S. Rule 4(b), and that choice has continuing effects for the case. If the estate has an original will and the case is e-filed, I.R.E.F.S. Rule 5(a) requires the original will to be filed conventionally within seven business days.
How much is the Jefferson County probate filing fee?
The opening filing fee is $166.00 under the Idaho Supreme Court Appendix A filing schedule effective July 12, 2024, for a petition for formal probate or an application for informal probate in the magistrate division.

Will I have a hearing in Jefferson County probate?
It depends on the route. Informal probate is handled by the registrar, meaning a magistrate judge or district judge, under Idaho Code § 15-1-307 and § 15-3-302.

Can I attend a Jefferson County probate hearing by phone or video?
Ask the clerk how the judge handles any request. Idaho R. Civ. P. 7.2 allows certain hearings by telephone or video teleconference at the court's discretion.
