Overview

Marathon County is located in Wisconsin with a population of approximately 139,091. The Marathon County Circuit Court handles all probate and estate matters for decedents who were domiciled in the county at the time of death.

Wisconsin probate is governed by Wisconsin Statutes Chapters 851-882. The process begins with filing an Application for Informal Administration (Form PR-1801) 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.

For smaller estates, Wisconsin offers a Transfer by Affidavit procedure if the estate is valued at $50,000 or less. This allows heirs to collect assets without full court supervision.

Filing fees in Wisconsin are set by statute. For formal and informal administration, the fee is 0.2% of the value of the property subject to administration (minimum $20).

Filing Process

Step 1: Determine If Probate Is Necessary

Before filing, assess whether formal probate is required:

  • Transfer by Affidavit: If the estate is valued at $50,000 or less, you may be able to use this simplified procedure to transfer assets without opening a court file.
  • Summary Settlement/Assignment: Available for certain estates where the value does not exceed specific statutory limits or where the estate is insolvent.
  • Trust administration: Assets held in a living trust generally do not require probate.

Step 2: File the Application

If formal probate is needed, file an Application for Informal Administration (Form PR-1801) with the Marathon County Circuit Court. Include:

  • Original Will and codicils (if any)
  • Certified death certificate
  • Order for Hearing and Notice (Form PR-1803)
  • Filing fee (0.2% of estate value)
  • Any additional required documents (e.g., Waiver and Consent forms)

Wisconsin offers mandatory e-filing for attorneys and optional e-filing for self-represented litigants.

Step 3: Provide Notice

After filing, you must:

  • Mail notice of the hearing to all heirs, beneficiaries, and interested parties at least 20 days before the hearing
  • Publish notice in a newspaper of general circulation in Marathon County (typically the Wausau Daily Herald) for three successive weeks

Step 4: Attend the Hearing

The court will schedule a hearing on the application. At the hearing, the judge or court commissioner reviews the application and, if approved, issues Letters Testamentary or Letters of Administration (Form PR-1810 or PR-1811).

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify creditors and set a deadline for claims (typically 3-4 months)
  • Inventory and appraise all estate assets within 6 months
  • Pay valid creditor claims and estate expenses
  • File federal and state tax returns as needed
  • Distribute assets to beneficiaries
  • File a final accounting and petition for discharge
