Express Fire Protection sent a pre-lien notice to property owners and contractors. Purcell Investments challenged whether the notice was timely under Oklahoma law. The court ruled that the 75-day deadline for sending pre-lien notice starts from the last day a subcontractor supplies labor, materials, or equipment—not the first day. This decision upholds mechanics' lien rights for subcontractors who follow the correct timing rule.
In Oklahoma, count your 75-day pre-lien notice deadline from your LAST supply date on the project, not your first. Missing this deadline can kill your lien rights.
Track when you make your final delivery or perform your last work. That date triggers the 75-day clock for sending pre-lien notice to the property owner and contractor.
