Okla. Stat. tit. 60, § 60-70: Boundaries and fences

Coterminous owners are mutually bound equally to maintain:

1. The boundaries and monuments between them.

2. The fences between them, unless one of them chooses to let

his land lie open as a public common, in which case, if he

afterwards encloses it, he must refund to the other a just

proportion of the value, at that time, of any division fence made by

the latter. R.L. 1910 Sec. 6645.
