If you miss a deadline by even one day, your lien rights may be extinguished forever. This guide outlines the critical steps for suppliers to secure their payment rights.

Supplier pitfalls
Common Supplier Mistakes in Wisconsin
Missing the 60-day Written Notice of Claim
Many suppliers fail to send the required preliminary notice early in the project, invalidating their future lien rights.
Filing the lien after 6 months
Waiting too long to file. The deadline is strict and often does not extend for weekends or holidays.
Missing the 2-year enforcement deadline
Filing a lien is not enough; you must enforce it (file a lawsuit) before the enforcement period expires.
