September 10, 2026 (2 min read)

Oklahoma lawmakers approved changes to more than 40 business entity laws during the 2025 - 2026 legislative session, including new provisions concerning updated penalties for fraud connected to securities and take-overs, new requirements for international corporate agents, and transparency requirements for proxy advisors.

The 2026 edition of CSC’s Oklahoma Laws Governing Business Entities Annotated captures these and other changes. Published in collaboration with legal publisher LexisNexis, the book is a comprehensive yet portable collection of Oklahoma statutes and regulations that allows practitioners in the state to conduct research more effectively, complete transactions more efficiently, and advise clients with confidence. 

The book features the full text of Title 18 — Corporations, and Title 54 — Partnerships from the Oklahoma Statutes. It also includes a curated selection of sections from related titles and regulations from the Oklahoma Administrative Code covering business records, corporate taxation, trademarks, and securities, as well as Articles, 1, 8, 9, and 12 from the Uniform Commercial Code.

All statutory content is current through Chapter 350 of the 60th Oklahoma Legislature. The Table of Sections Affected lists the sections that were added or amended, and the Legislative Analysis provides an overview of how these changes have affected the law.

The Oklahoma deskbook is fully annotated with the latest case notes from state and federal courts interpreting the law, with more than a dozen new notes added since the 2025 edition. New case notes are marked in the text with a gray bar.
