State laws vary and no attempt is made to discuss laws of states other than Oklahoma.
For advice about how these issues might apply to your individual situation, consult an attorney. If you want the land unenclosed and used as a commons by the public, you can leave your land without a fence. Such fences must be kept in good repair throughout the year unless both landowners along the fence agree otherwise in writing. Willful failure to keep domestic and exotic animals properly confined is a misdemeanor in Oklahoma. The rails or boards need to be fastened to good substantial posts not more than 10 feet apart where rails are used, and not more than eight feet apart where boards are used.
