Okla. Stat. tit. 60, § 60-175.45: Grant deemed absolute as to purchasers or encumbrances

for value - Notice of restrictions - Intent of Legislature.

(a) Where an express trust is created in relation to real

property; any grant, deed, conveyance, lease, easement, encumbrance,

assignment, or release by the trustee with respect to such real

property or interest therein shall be deemed authorized and binding

upon the trust in favor of purchasers or encumbrances for value

without either (i) actual notice of restrictions or limitations

established by the trust upon the trustee, or (ii) the constructive

notice as provided in subsection (b) hereof.

(b) If the instrument establishing the trust is recorded in the

county where the real property is located, said purchasers or

encumbrances for value shall be charged with constructive notice of

the restrictions and limitations contained in such instrument.

(c) It is the intent of the Legislature that trusts are private

instruments and it shall not be necessary to record the instrument

establishing a trust unless the trustor desires to put the public on

notice of restrictions or limitations upon the powers of the

trustee, in which case the same must be recorded.
