Detailed answer — How to open probate in Wisconsin from another state

1. Do you need probate?

Not every estate must go through full probate. Probate is usually needed when the decedent owned assets solely in their name (bank accounts, real estate, titled property) that do not have a payable-on-death beneficiary, joint owner, or trust designation. Small estate procedures may be available for modest estates. Contact the circuit court clerk in the county where your sibling lived to confirm whether probate is required in your situation.

2. Where to file

File the probate case in the Wisconsin circuit court for the county where the decedent was domiciled (their permanent home) at the time of death. The court clerk can tell you which paperwork the county requires and local filing fees.

For the Wisconsin probate statutes that govern procedures and priority for appointment of a personal representative, see the Wisconsin statutes for probate (chapters 851–879): https://docs.legis.wisconsin.gov/statutes/statutes/851.

3. Who can start the case and who becomes personal representative?

If there is a will, the person named as executor in the will usually petitions to be appointed. If there is no will, a family member or other interested person (often a surviving spouse, adult child, parent, or sibling) may petition to be appointed administrator. The court follows statutory priority when multiple people ask to serve. If you live out of state you can still petition to serve as personal representative; the court will consider any competing claims and may require additional paperwork (such as a bond).

4. Typical documents you will need

• Original will (if one exists).
• Certified copy of the death certificate (several certified copies are often useful).
• Petition for probate or appointment forms required by the county (court form names vary).
• Affidavit of heirs or beneficiary lists.
• Oath or acceptance of appointment by the proposed personal representative.
• Proof of identification and address for the petitioner.
• Information about major assets, creditors, and beneficiaries (account numbers, description of real estate, contact information).

5. Filing from out of state — practical steps

1. Contact the circuit court clerk in the county where your sibling lived. Ask for the probate intake packet, the list of required forms, current filing fees, and local practice (some counties let you file by mail or electronically).
2. Obtain several certified death certificates from the state or county that issued them.
3. Gather and, if needed, arrange to have the original will transported to Wisconsin or a certified copy produced (the court generally prefers the original will if one exists).
4. Sign any required petition and oath. If you cannot appear in person for an initial hearing, ask the clerk if the court accepts notarized or remotely sworn documents or whether you can appear by phone/Zoom for the hearing.
5. Expect to post a bond if required. A will may waive bond for the named executor; if there is no will, courts often require a bond to protect creditors and beneficiaries unless the court waives it for good cause.
6. If the clerk or court requires a local agent for service of process because you are out of state, ask whether appointing a Wisconsin resident agent or hiring local counsel is needed. Practices vary by county and situation.

6. Small estate options and alternatives

Wisconsin offers simplified procedures for smaller estates and for collecting specific types of assets (for example, certain bank accounts, motor vehicle transfers, or beneficiary-designated assets). If the estate qualifies for a simplified process, you may avoid full probate or reduce paperwork. The circuit court clerk and Wisconsin court forms will indicate what procedures apply.

7. Timeline and fees

Timing depends on the estate’s complexity, whether there are disputes, and how quickly you locate assets and creditors. Initial appointment often takes a few weeks when paperwork is complete. Closing the estate can take several months to a year or more. County filing fees and bond premiums vary. Ask the county clerk for the current fee schedule.

8. When to hire an attorney

Consider hiring a Wisconsin probate attorney if the estate has real estate, contested claims, unclear ownership, out-of-state assets, complex tax issues, or if multiple people claim priority to be personal representative. An attorney can file paperwork on your behalf, represent you at hearings, and handle local requirements you can’t easily manage from another state.

Helpful Hints

• Call the county circuit court clerk first. They can tell you the exact local forms, fees, and whether the court accepts mailed filings or remote appearances.
• Get several certified copies of the death certificate right away — banks and other institutions often require them.
• If you are named executor in a will, keep a copy of the will available and locate the original if possible. The court usually wants the original.
• Inventory assets early. Banks sometimes freeze accounts; knowing account numbers and contact information speeds access and helps protect assets.
• Ask whether the will waives bond. A bond can be expensive and time-consuming if not waived.
• If you cannot travel, ask whether the court accepts notarized consents and whether hearings can be attended remotely. Many counties accommodate out-of-state petitioners to an extent.
• Consider a local probate attorney if you can’t be in Wisconsin for court dates or if the estate includes real estate or complex assets in Wisconsin.
• Preserve important documents (titles, deeds, policy statements) and make a clear list of potential creditors to avoid surprises later.
• Keep careful records of estate expenses and distributions. Courts require accounting of how estate money was handled.
