Wisconsin probate timeline — frequently asked questions

How long does probate take in Wisconsin?

Most Wisconsin estates take 6 to 12 months, and courts expect a case closed within 12 months of filing, with an 18-month hard deadline before the court steps in. The creditor claim window, set by court order, runs 3 to 4 months, which sets the floor.

How is the Wisconsin creditor claim deadline set?

Unlike states with a fixed number of months written into statute, Wisconsin has the court, or the probate registrar under informal administration, set the deadline by order — not less than 3 nor more than 4 months from the date of that order, under Wis. Stat. § 859.01.

What is informal administration in Wisconsin?

A track supervised by the county Probate Registrar that needs no attorney, used for most uncontested Wisconsin estates. Formal administration, which requires a licensed attorney under Wis. Stat. § 865.03, applies to contested or more complex cases.

When is the Wisconsin Inventory due?

Generally within 6 months of filing the petition for administration, though the exact date is set by the Probate Registrar or court on the Notice of Estate Administration Deadlines and can vary by county.
