Before you begin — know the assets and liabilities

Before you file anything in Lake County, identify what the decedent owned, what was jointly owned, what named a beneficiary and what debts still exist. Montana venue turns on the decedent's domicile or, for a non-Montana decedent, where Montana property was located (Mont. Code Ann. § 72-3-112), so the asset list affects both the estate settlement plan and where the filing belongs.

Sunset's estate settlement tools search more than 2,300 financial institutions for accounts and assets, organize what you find and help you decide what belongs in the Lake County probate packet before you contact the clerk of district court.

Which court handles jurisdiction

Probate for Lake County is filed with the clerk of district court at the Lake County Courthouse in Polson. Lake County is one of two counties in Montana's 20th Judicial District, with Sanders County, and that judicial district assignment comes from Mont. Code Ann. § 3-5-101. Sanders County has its own clerk of district court in Thompson Falls, so a Lake County estate is filed in Lake County.

The District Court has exclusive jurisdiction of all probate matters, and District Courts have original jurisdiction over all civil and probate matters (Mont. Code Ann. § 72-3-111, § 3-5-302). Montana's courts of limited jurisdiction, including the Lake County Justice Court and City Courts in Polson, Ronan and St. Ignatius, have no probate jurisdiction (Mont. Code Ann. § 3-10-301, § 3-11-102).

The jurisdiction process

  1. Choose the right Montana filing path. Informal probate uses an application to the clerk, and formal probate uses a petition with notice under Montana's formal testacy statutes (Mont. Code Ann. § 72-1-103, § 72-3-301).
  2. Prepare the Lake County packet. Use the statewide probate forms at courts.mt.gov/Forms/endoflife, including the Application for Informal Probate, proposed statement of informal probate and Letters of Authority when the informal route fits.
  3. File with the clerk of district court in Lake County at 106 4th Avenue E, Room 301, Third Floor, Polson. A self-represented personal representative files on paper because courts.mt.gov states that e-filing is not available to self-represented litigants.
  4. Pay the filing fee. The probate commencement charge is $100.00, current in the 2025 Montana Code Annotated, made up of the $70 probate fee, the $20 additional filing fee and the $10 court information technology user surcharge (Mont. Code Ann. § 25-1-201, § 25-1-202, § 3-1-317).
  5. Wait for the clerk's informal-probate review or for the court to schedule any formal matter. In an informal proceeding, the clerk of district court makes the statutory findings, may deny an application that does not meet them and issues the written statement of informal probate only after at least 120 hours have elapsed since death (Mont. Code Ann. § 72-3-212, § 72-3-214, § 72-3-215).
  6. Use Lake County's calendars only as directed. The county publishes Law and Motion Days, Department 1 on Wednesday at 9 am and Department 2 on Thursday at 9 am, with Zoom links, but remote appearance depends on the district judge and local rules. Montana permits testimony by contemporaneous transmission only for good cause in compelling circumstances with safeguards (Mont. R. Civ. P. 43(a)).
  7. Qualify before acting for the estate. Before receiving letters, the personal representative files any required bond and a statement of acceptance of the duties of office (Mont. Code Ann. § 72-3-512). The statewide forms call the authority document Letters of Authority at courts.mt.gov/Forms/endoflife.
  8. Give required creditor notice and administer the estate. After appointment, the personal representative publishes notice to creditors once a week for 3 successive weeks, and creditor claims are measured from the first publication as provided in Mont. Code Ann. § 72-3-801, with the outside bar in Mont. Code Ann. § 72-3-803.
  9. Prepare the inventory and close the estate when administration is complete. The personal representative prepares an inventory within 9 months after appointment (Mont. Code Ann. § 72-3-607) and may use the appropriate Montana closing statement procedure when the statutory requirements are met (Mont. Code Ann. § 72-3-1104).

Forms and documents

Probate forms in Lake County

Lake County's clerk of district court page says the clerk does not provide legal forms and directs readers to the Montana Law Library. For probate forms, start with the Montana Judicial Branch forms page at courts.mt.gov/Forms/endoflife.

Timeline

  1. Lake County publishes Law and Motion Days for Department 1 on Wednesday at 9 am and Department 2 on Thursday at 9 am. These are local calendar settings, and local rules and the district judge control whether a particular probate matter is placed there.
  2. The Lake County page publishes Zoom links for those Law and Motion calendars. Do not rely on Zoom for a probate appearance until the clerk or the court confirms the procedure under local rules and any order in your case.
  3. If the matter is formal probate, the petition proceeds with notice under the formal testacy statutes, and contested scheduling is handled by the district judge (Mont. Code Ann. § 72-3-301, § 72-3-307).

Local nuance

Lake County-specific considerations

Local pointWhat it means for a Lake County estate
Judges sit in PolsonThe 20th Judicial District covers Lake and Sanders Counties, but both Department 1 and Department 2 sit in Polson for the district court listed for Lake County. A Lake County filing starts with the clerk of district court in Lake County (Mont. Code Ann. § 3-5-101).
Limited-jurisdiction courts are not estate filing courtsLake County's limited courts include the Polson City Judge, Polson Justice of Peace, Ronan City Judge and St. Ignatius City Judge. Probate belongs in District Court, not those courts, because District Court has exclusive jurisdiction of all probate matters (Mont. Code Ann. § 72-3-111, § 3-10-301, § 3-11-102).
Clerk service boundariesThe Lake County clerk lists probate cases among the case types maintained by the office, but the clerk cannot give legal advice, does not provide notary service and states that legal forms are not provided by the clerk.

When to hire an attorney

Consider hiring a Montana probate attorney if the will is disputed, heirs disagree, creditors are active, real property must be sold, a fiduciary income tax issue may arise, or the clerk does not approve an informal application and a formal probate petition with notice is needed.

File with the clerk of district court in Lake County at 106 4th Avenue E, Room 301, Third Floor, Polson, MT 59860. Montana venue is based on the decedent's domicile, or for a non-Montana decedent, a county where Montana property was located (Mont. Code Ann. § 72-3-112).

Is Lake County probate filed in District Court?

Yes. The District Court has exclusive jurisdiction of all probate matters, and Montana District Courts have original jurisdiction over all civil and probate matters (Mont. Code Ann. § 72-3-111, § 3-5-302). In Lake County, the filing office is the clerk of district court in Polson.

Can I e-file a Lake County probate if I do not have a lawyer?

Does Lake County publish probate hearing days?

Code Ann. § 72-3-301, § 72-3-307).

May I use Zoom for a Lake County probate hearing?

Lake County publishes Zoom links for the two Law and Motion calendars, but that is not a statewide right to appear remotely.

Can I look up a Lake County probate case online?
