Okla. Stat. tit. 60, § 60-1607.6: Removal of trustee

A. The settlor, a co-trustee, or a beneficiary may request the

court to remove a trustee, or a trustee may be removed by the court

on its own initiative.

B. The court may remove a trustee if:

1. The trustee has committed a serious breach of trust;

2. Lack of cooperation among co-trustees substantially impairs

the administration of the trust;

3. Due to unfitness, unwillingness, or persistent failure of

the trustee to administer the trust effectively, the court

determines that removal of the trustee best serves the interests of

the beneficiaries; or

4. There has been a substantial change of circumstances or

removal is requested by all of the qualified beneficiaries, the

court finds that removal of the trustee best serves the interests of

all of the beneficiaries and is not inconsistent with a material

purpose of the trust, and a suitable co-trustee or successor trustee

is available.

C. Pending a final decision on a request to remove a trustee,

or in lieu of or in addition to removing a trustee, the court may

order such appropriate relief under subsection B of Section 175.57

of Title 60 of the Oklahoma Statutes as may be necessary to protect

the trust property or the interests of the beneficiaries.
