Overview

Rock County is located in Wisconsin with a population of approximately 164,000. The Rock 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 a Petition for 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.

Wisconsin offers a simplified procedure known as Transfer by Affidavit for estates valued at $50,000 or less. This allows heirs to collect assets without full court supervision.

Wisconsin does not have a statutory fee schedule for attorneys or personal representatives based on a percentage of the estate; 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:

  • Transfer by Affidavit: If the estate is valued at $50,000 or less, you may be able to transfer assets via affidavit without court supervision.
  • Survivorship: Property held in joint tenancy or survivorship marital property passes directly to the surviving owner.
  • 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 Administration (Form PR-1801) with the Rock 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 for estates over $10,000)
  • Waiver and Consent forms from interested parties (if applicable)

E-filing is mandatory for attorneys and optional for self-represented litigants in Wisconsin circuit courts.

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 Rock County (such as The Janesville Gazette or Beloit Daily News) for three successive weeks.

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 or court commissioner reviews the petition and, if approved, issues Letters Testamentary or Letters of Administration.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify creditors and resolve claims (creditors typically have 3-4 months to file claims).
  • 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 Estate Receipt to close the estate.

Local Requirements
