Is an operating agreement required for an Oklahoma LLC?
No. Oklahoma law does not require an LLC to adopt an operating agreement. The Oklahoma Limited Liability Company Act (Title 18, Sections 2000 and following) permits one, but it is optional. It is still strongly recommended because it lets members override the statutory default rules.
