Overview

Waukesha County is located in Wisconsin with a population of approximately 406,978. The Waukesha County Probate 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 Domiciliary Letters 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 for the transfer of assets without full probate administration.

Wisconsin does not have a statutory fee schedule for attorney or personal representative fees; fees must be "reasonable" based on the services provided. However, the court charges a probate filing fee (inventory fee) of 0.2% of the net value of the property subject to administration.

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 using the Transfer by Affidavit form (Form PR-1831) without court supervision.
  • Survivorship: Assets held in joint tenancy or as survivorship marital property pass 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 or informal probate is needed, file an Application for Informal Administration (Form PR-1801) with the Waukesha County Probate Court. Include:

  • Original Will and codicils (if any)
  • Certified death certificate
  • Notice Setting Time to Hear Application and Deadline for Filing Claims (Form PR-1805)
  • Filing fee (based on estate value)
  • Waiver and Consent (Form PR-1803) from interested persons (optional but speeds process)

Note: E-filing is mandatory for most probate cases in Waukesha County.

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 Waukesha County (typically the Waukesha Freeman) for three successive weeks.

Step 4: Attend the Hearing

The court will schedule a hearing on the petition. If the petition is for informal administration and all waivers are filed, a hearing may not be required. Upon approval, the court issues Domiciliary Letters, granting the personal representative authority to act.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify creditors and allow 3 to 4 months for claims to be filed.
  • 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 Personal Representative's Statement to Close Estate (Form PR-1816) or a final account and petition for discharge.
