WI · PRIVATE CONSTRUCTION CLAIMS
Build the 30-day notice period into your filing schedule.
Section 779.06 generally requires filing within six months after the last covered contribution and an enforcement action within two years after the claim is filed.
Notices to check before filing
Serve the owner a notice of intent at least 30 days before timely filing, and serve a copy of the filed claim within 30 days afterward.
Where and how to file in Wisconsin
File the claim with the circuit court clerk for the county containing the land.
A filing mistake to avoid
An earlier preliminary notice does not replace the notice of intent described in §779.06(2).
Prepare your project records
Gather the last contribution date, both notice records, the filed claim, owner information, and the court filing receipt.
- Identify who hired you and whether the property is privately owned.
- Confirm your notice obligations and the event that starts each time limit.
- Verify the owner and property description using appropriate records.
- Reconcile invoices, payments, credits, and disputed amounts.
- Keep filing and service receipts, and calendar any enforcement deadline.
After the claim is filed
Filing does not guarantee payment or establish that a disputed claim is valid. Preserve the filed document and delivery evidence. If payment arrives, arrange the required release or satisfaction. If the balance remains unpaid, seek advice about enforcement before its separate deadline expires.
