Okla. Stat. tit. 60, § 60-1607.1: Accepting or declining trusteeship

A. Except as otherwise provided in subsection C of this

section, a person designated as trustee accepts the trusteeship:

1. By substantially complying with a method of acceptance

provided in the terms of the trust; or

2. If the terms of the trust do not provide a method or the

method provided in the terms is not expressly made exclusive, by

accepting delivery of the trust property, exercising powers or

performing duties as trustee, or otherwise indicating acceptance of

the trusteeship.

B. A person designated as trustee who has not yet accepted the

trusteeship may reject the trusteeship. A designated trustee who

does not accept the trusteeship within a reasonable time after

knowing of the designation is deemed to have rejected the

trusteeship.

C. A person designated as trustee, without accepting the

trusteeship, may:

1. Act to preserve the trust property if, within a reasonable

time after acting, the person sends a rejection of the trusteeship

to the settlor or, if the settlor is dead or lacks capacity, to a

qualified beneficiary; and

2. Inspect or investigate trust property to determine potential

liability under environmental or other law or for any other purpose.
