Supplier pitfalls
Common Supplier Mistakes in South Dakota
Missing the 60-day Notice of Furnishing
Many suppliers fail to send the required preliminary notice early in the project, invalidating their future lien rights.
Filing the lien after 120 days
Waiting too long to file. The deadline is strict and often does not extend for weekends or holidays.
Missing the 6-year enforcement deadline
Filing a lien is not enough; you must enforce it (file a lawsuit) before the enforcement period expires.
