Idaho Code § 68-101: Trustees — Power of district court to appoint.

When a trust exists without any appointed trustees or where any or all of the trustees renounce, die, or are discharged, the district court of the county where the trust property or some portion thereof is situated, must appoint another trustee to direct the execution of the trust. The court may, in its discretion, appoint the original number or any less number of trustees.
