Overview

Oneida County is located in Wisconsin with a population of approximately 38,175. The Oneida 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.

Transfer by Affidavit is available for estates valued at $50,000 or less. This simplified procedure allows heirs to collect assets without full court supervision.

Wisconsin does not have a statutory fee schedule for attorneys or personal representatives; fees must be "just and reasonable" based on the services performed.

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.
  • Summary Settlement: Available for estates where the value does not exceed costs, expenses, allowances, and claims, or when the estate is under $50,000 and there is a surviving spouse or minor children.
  • 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 Oneida 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)

Wisconsin offers mandatory e-filing for most probate cases.

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 Oneida County (such as The Northwoods River News) for three successive weeks.

Step 4: Attend the Hearing

The court will schedule a hearing on the petition. At the hearing, the judge or probate registrar reviews the petition and, if approved, issues Letters Testamentary (or Domiciliary Letters).

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify creditors (deadline for claims is typically 3-4 months from the date of the court order)
  • Inventory and appraise all estate assets within 6 months
  • Pay valid creditor claims
  • File federal and state tax returns as needed
  • Distribute assets to beneficiaries
  • File a final accounting and Estate Receipt (Form PR-1815) to close the estate

Local Requirements
