Overview

Oconto County is located in Wisconsin with a population of approximately 40,037. The Register in Probate 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 Domiciliary Letters for testate estates or Letters of Administration for intestate estates.

Simplified Procedures: Wisconsin offers a Transfer by Affidavit procedure for estates valued at $50,000 or less. This allows heirs to collect assets without opening a formal probate estate. There is also a Summary Settlement procedure for small estates where the assets do not exceed the expenses, or for estates not exceeding $50,000 where the decedent is survived by a spouse or minor children.

Fee Structure: Wisconsin charges a probate filing fee based on the value of the estate's assets. For estates valued over $10,000, the fee is 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 use the Transfer by Affidavit (Form PR-1831) to collect assets without court supervision.
  • Summary Settlement/Assignment: Available for certain small estates or when the estate is insolvent.
  • 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 Oconto County Register in Probate. Include:

  • Original Will (if the decedent died testate)
  • Certified Death Certificate
  • Order for Hearing (if formal administration)
  • Filing fee (based on estate value)
  • Waivers of Consent from heirs (for informal administration)

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 (or notice of informal administration) to all heirs, beneficiaries, and interested parties.
  • Publish notice in a newspaper of general circulation in Oconto County, such as the Oconto County Reporter, typically for three successive weeks if required by the court.

Step 4: Attend the Hearing

For formal probate, the court will schedule a hearing on the petition. At the hearing, the judge or court commissioner reviews the petition and, if approved, issues Domiciliary Letters. For informal probate, the Register in Probate may issue letters without a hearing if all requirements are met.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify creditors and set a deadline for claims (usually 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 Estate Receipt and Statement of Personal Representative to Close Estate (Form PR-1816) to discharge the estate.

Local Requirements

Oconto County-Specific Procedures

  • E-filing: Wisconsin utilizes a mandatory e-filing system for attorneys. Self-represented parties may opt-in to e-file.
  • Inventory Fee: The 0.2% filing fee is often calculated and paid when the Inventory is filed.
  • Publication: Notice is typically published in the Oconto County Reporter.
  • Guardian ad Litem: The court may appoint a Guardian ad Litem (GAL) if there are minor or incompetent heirs, which will require an additional deposit/fee.

Always check with the Register in Probate for the most current local rules and checklist requirements.
