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.
