Supplier pitfalls
Common Supplier Mistakes in Oklahoma
Missing the 75-day Pre-Lien Notice
Many suppliers fail to send the required preliminary notice early in the project, invalidating their future lien rights.
Filing the lien after 90 days
Waiting too long to file. The deadline is strict and often does not extend for weekends or holidays.
Missing the 1-year enforcement deadline
Filing a lien is not enough; you must enforce it (file a lawsuit) before the enforcement period expires.
