Good News for Oklahoma Contractors

Oklahoma does not require a pre-lien preliminary notice for most contractors. You still must file the lien within the deadline and in the correct recording office.

Does the Property Type Change Your Deadline?

Same 4-month deadline for both. Oklahoma does not significantly distinguish commercial vs residential.
