Requirements one by one
Start with the court's order, not a fixed publication interval
Wisconsin Statutes §§ 859.01 and 859.02 direct the court or informal-administration probate registrar to set the claim deadline when the administration application is filed. The date must be at least three and no more than four months after the order.
Wisconsin Statutes §§ 859.07 and 879.05 require publication, with the first insertion within 15 days after the order. Section 879.05 makes it a class 3 notice in an eligible county newspaper as the court directs, and § 879.07 uses a publication affidavit as proof.
Separate mandatory public-agency notice from optional creditor notice
For the listed institutional, public-obligation, long-term-care, or assistance circumstances, the representative must send the specified agency or county clerk its form by registered or certified mail at least 30 days before the deadline.
The representative may notify any potential claimant of the filing deadline and court. That notice matters because an otherwise qualifying known or reasonably ascertainable creditor must show that the representative did not give notice at least 30 days before the deadline and that the creditor lacked actual knowledge of the proceeding and court.
File the sworn claim in court
Wisconsin Statutes § 859.13 requires a writing stating the nature and ascertainable amount, the claimant's post-office address, that the amount is justly due, the due date if unmatured, uncredited payments, and known offsets. A claim involving marital property identifies the statutory classification. A written instrument or copy with endorsements is attached when available.
Use the one-year/30-day route only for a creditor without notice
A creditor meeting § 859.02(2)(b) files under § 859.48 within one year after death and within 30 days after the earlier of targeted notice or actual knowledge of the administration and court. The creditor then serves or mails a copy to the representative or estate attorney within 10 days and bears the burden of proving the missing-notice circumstances.
An allowed post-distribution claim may proceed against distributees, subject to the statutory limits. This route does not extend another applicable limitation.
Preserve the named exception tracks
Wisconsin Statutes § 859.02 lists tort, specified Wisconsin tax and benefit claims, funeral and administration expenses, and United States claims. A surviving pending action obtains filed-claim status through timely substitution proof under Wisconsin Statutes § 859.03 gives a timely substituted pending action filed-claim status. Section 859.43 preserves enforcement of mortgages, pledges, liens, and other security agreements. The tort route in § 859.45 survives a missed probate deadline, but the court then has no duty to protect that claimant before distribution.
What trips people up
The deadline is a date in the court's order, not a fixed number of months after first publication.
Wisconsin's general claimant notice is permissive, but failure to give it to a known or reasonably ascertainable creditor can open the constrained § 859.48 route.
The one-year period is not a general outer bar for every claimant. It belongs to the creditor-without-notice procedure.
The ordinary filing deadline cannot be waived merely because a claim seems valid.
Common questions
Where does a creditor file?
The claim is filed in the court administering the estate.
Can an unnoticed creditor file after the ordered deadline?
Only if the creditor proves all § 859.02(2)(b) circumstances and complies with the one-year, 30-day, and 10-day requirements in § 859.48.
Does a mortgage lien require the ordinary claim route?
No. Section 859.43 preserves a separate proceeding to enforce the security.
