Overview

Shiawassee County is located in Michigan with a population of approximately 68,000. The Shiawassee County Probate Court handles all probate and estate matters for decedents who were domiciled in the county at the time of death.

Michigan probate is governed by the Estates and Protected Individuals Code (EPIC). The process begins with filing a Petition for Probate and/or Appointment of Personal Representative (Form PC 559) to admit the will and appoint a personal representative. The court then issues Letters Testamentary for testate estates or Letters of Administration for intestate estates.

Michigan offers a simplified procedure for small estates. For decedents dying in 2026, if the estate is valued at $53,000 or less (adjusted annually for cost of living), you may file a Petition and Order for Assignment (Form PC 556).

Michigan does not have a statutory fee schedule for attorneys or personal representatives; fees must be reasonable and are often based on hourly rates or a flat fee agreed upon by the parties.

Filing Process

Step 1: Determine If Probate Is Necessary

Before filing, assess whether formal probate is required:

  • Small Estate Petition: If the estate is valued at $53,000 or less (for 2026 deaths), you may file a Petition for Assignment.
  • Transfer by Affidavit: For estates valued at $27,000 or less (indexed for inflation), a successor may claim assets via affidavit without court involvement.
  • Trust administration: Assets held in a living trust generally do not require probate.

Step 2: File the Petition

If formal probate is needed, file a Petition for Probate and/or Appointment of Personal Representative (PC 559) with the Shiawassee County Probate Court. Include:

  • Petition for Probate (PC 559)
  • Original will and codicils (if any)
  • Certified death certificate
  • Filing fee ($175)
  • Testimony to Identify Heirs (PC 565)

Note: Shiawassee County Probate Court currently requires filings to be made in person or by mail; e-filing is not yet available for probate matters.

Step 3: Provide Notice

After filing, you must:

  • Mail notice of the hearing to all heirs, beneficiaries, and interested parties at least 14 days before the hearing
  • Publish notice in a newspaper of general circulation in Shiawassee County (such as The Argus-Press) for one time if the address of an interested person is unknown.

Step 4: Attend the Hearing

The court will schedule a hearing on the petition, typically 3 to 4 weeks after filing. At the hearing, the judge reviews the petition and, if approved, issues Letters of Authority.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Publish notice to creditors (4-month claim period)
  • Inventory and appraise all estate assets within 91 days
  • Pay valid creditor claims
  • File federal and state tax returns as needed
  • Distribute assets to beneficiaries
  • File a Notice of Continued Administration if the estate is open longer than one year, or a Sworn Statement to Close Unsupervised Administration to close the estate.
