Before you begin — know the assets and liabilities

Before you file anything in Mackinac County, make a working list of the decedent's assets, debts, titled property, accounts, beneficiaries and possible creditors. The right estate settlement path depends on what the estate owns, whether real estate is involved, whether someone needs letters of authority, and whether the case belongs at the St. Ignace probate counter under Michigan venue rules.

Sunset helps families organize that first inventory by searching across 2,300 financial institutions for accounts and assets. That asset picture makes it easier to choose between transfer by affidavit, assignment of property, informal probate, formal probate or a full estate settlement plan with a personal representative.

Which court handles jurisdiction

Mackinac County Probate Court serves decedent estates for people domiciled in Mackinac County at death, including communities such as St. Ignace, Mackinac Island, Naubinway, Moran, Rudyard, Hessel and Cedarville. If the decedent was not domiciled in Michigan, venue can be in a Michigan county where the decedent left property (MCL 700.3201).

Mackinac County is in the 6th Probate District with Luce County. The district shares a probate judge, but each county keeps its own probate register and courthouse counter. For a Mackinac County estate, file at the Mackinac County Courthouse in St. Ignace.

The jurisdiction process

  1. Choose the local filing office. If venue is in Mackinac County under MCL 700.3201, use Mackinac County Probate Court at the Mackinac County Courthouse, 100 S. Marley Street, St. Ignace, MI 49781.
  2. Select the correct statewide SCAO form. Common starting points are PC 556 for assignment of property, PC 558 for informal probate and appointment of a personal representative, and PC 559 for formal probate and appointment before a judge.
  3. Use the right filing channel. Attorneys must use MiFILE for Mackinac County estates. Self-represented filers may use MiFILE, but are not mandated users, and should ask the probate register how the St. Ignace office wants any paper submission delivered or mailed.
  4. Pay the opening cost that fits the filing. Opening a decedent estate costs $175.00 for 2026, based on MCL 600.880 and MCL 600.1986, plus the inventory fee under MCL 600.871. A petition for assignment of property has a $25.00 filing fee for 2026 under MCL 600.880, and the inventory fee still applies.
  5. Give required notices. On the informal track, written information of probate must be given within 28 days after informal probate is granted (MCL 700.3306). After appointment, the personal representative handles creditor notice under MCL 700.3801.
  6. Attend any hearing the court sets. Informal probate can be handled by the probate register when the statutory requirements are met. Formal proceedings and disputed matters go to a judge. Uncontested decedent-estate hearings are presumed to use videoconferencing when allowed under MCR 5.140 and MCR 2.407, but the court can require in-person attendance.
  7. Obtain letters of authority if a personal representative is appointed. The Michigan authority document is PC 572, Letters of Authority for Personal Representative. Certified copies cost $10.00 for certification plus $1.00 per page for 2026 under MCL 600.2546.
  8. Administer and close the estate. The personal representative gathers assets, deals with claims, files the inventory information due under MCR 5.307, distributes property and closes the estate through the appropriate SCAO closing form or court order.

Local nuance

Mackinac County-specific considerations

Mackinac County is a two-county probate district county, which changes the name of the court but not the filing location. The Michigan Trial Court Directory lists Mackinac as Mackinac/Luce Probate District 6, court code PD6-2, and Luce as the partner county. Mackinac estates are still filed with the Mackinac County probate register in St. Ignace.

The county's own decedent-estate information page includes older dollar figures for some probate filings and small-estate information. For 2026 filing guidance, use the current statewide statutory amounts: $175.00 to open a decedent estate under MCL 600.880 and MCL 600.1986, $25.00 for assignment of property under MCL 600.880, plus any inventory fee under MCL 600.871.
