Okla. Stat. tit. 60, § 60-175.23: Jurisdiction of district court regarding trusts - Venue

- Parties - Applicable statutes.

A. The district court shall have original jurisdiction to

construe the provisions of any trust instrument; to determine the

law applicable thereto; the powers, duties, and liability of

trustee; the existence or nonexistence of facts affecting the

administration of the trust estate; to require accounting by

trustees; to surcharge trustee; and in its discretion to supervise

the administration of trusts; and all actions hereunder are declared

to be proceedings in rem.

B. The venue of such actions shall be in the county where the

trustees or any cotrustee resides. Upon obtaining jurisdiction the

same shall not be divested by the removal of the trustee from the

county where the action is commenced.

C. Actions hereunder may be brought by a trustee, beneficiary,

or any person affected by the administration of the trust estate.

If the action is predicated upon any act or obligation of any

beneficiary, the beneficiary shall be a necessary party to the

proceedings. The only necessary parties to such actions shall be

those persons designated as beneficiaries by name or class in the

instrument creating the trust and who have a vested interest in the

trust which is the subject of the action, those persons currently

serving as trustees of the trust, and any persons who may be

actually receiving distributions from the trust estate at the time

the action is filed. Contingent beneficiaries designated by name or

class shall not be necessary parties.

D. The provisions of the statutes governing civil procedure,

commencement of action, process, process by publication, appointment

of guardians ad litem, supersedeas and appeal, shall govern all

actions and proceedings brought under provisions of this act.

E. A court of competent jurisdiction may, for cause shown and

upon notice to the beneficiaries, relieve a trustee from any or all

of the duties and restrictions which would otherwise be placed upon

the trustee by this act, or wholly or partly excuse a trustee who

has acted honestly and reasonably from liability for violations of

the provisions of this act.
