In This TopicIdaho TrustsTopic 2 of 14: Trustee Duties

A trustee has a general duty to administer a trust for the benefit of the beneficiaries, and Idaho law adds specific duties (Idaho Code § 15-7-301). Part 3 of chapter 7 of Title 15 sets out the trustee’s standard of care, the duty to keep beneficiaries informed, when a bond is required, when a trustee is personally liable, time limits on claims, and how a trustee can be removed (Idaho Code §§ 15-7-301 through 15-7-308).

This page matters to anyone serving as a trustee and to beneficiaries who want to know what they can expect. Some of these rules depend on the trust document itself. For example, the standard of care applies “except as otherwise provided by the terms of the trust” (Idaho Code § 15-7-302), and a bond may be required by the terms of the trust (Idaho Code § 15-7-304).

The General Duty: Administer the Trust for the Beneficiaries

A trustee has a general duty to administer a trust expeditiously for the benefit of the beneficiaries. Except as specifically provided, the Uniform Probate Code does not change that duty (Idaho Code § 15-7-301).

The code also says that trust administration should “proceed expeditiously consistent with the terms of the trust,” without court orders or approval, subject to the court’s jurisdiction as invoked by interested parties or as otherwise exercised as provided by law (Idaho Code § 15-7-201(b)).

Standard of Care: The Prudent Person Rule

Unless the trust terms say otherwise, a trustee dealing with trust assets must observe the standards “that would be observed by a prudent man dealing with the property of another” (Idaho Code § 15-7-302). In plain terms, the trustee must act as a careful person would when handling someone else’s property.

A trustee who has special skills must use them. The same applies to a trustee who was named on the basis of representations of special skills or expertise (§ 15-7-302).

Duty to Inform and Account to Beneficiaries

The trustee must keep the beneficiaries reasonably informed about the trust and its administration (Idaho Code § 15-7-303). The code adds three specific requirements:

Requirement	When	Idaho Code
Tell the current beneficiaries in writing which court the trust is registered in, and the trustee’s name and address. If possible, also tell one or more persons who may represent beneficiaries with future interests under section 15-1-403.	Within 30 days after the trustee accepts the trust	§ 15-7-303(a)
Give the beneficiary a copy of the trust terms that describe or affect the beneficiary’s interest, plus relevant information about trust assets and the particulars of administration.	Upon reasonable request	§ 15-7-303(b)
A beneficiary is entitled to a statement of the trust accounts annually and on termination of the trust or change of trustee.	Upon reasonable request	§ 15-7-303(c)

For how and where a trust is registered, see Trust Registration and Court Jurisdiction.

Duty to Provide a Bond

A bond secures the trustee’s performance of the trustee’s duties. An Idaho trustee does not need to provide a bond unless one of these applies (Idaho Code § 15-7-304):

• The terms of the trust require it.
• A beneficiary reasonably requests it.
• The court finds it necessary to protect beneficiaries who cannot protect themselves and whose interests are not otherwise adequately represented.

On petition of the trustee or another interested person, the court may excuse a bond requirement, reduce the bond amount, release the surety, or allow a substitute bond (§ 15-7-304). A required bond is filed in the court of registration or other appropriate court, in amounts and with sureties and liabilities as provided in sections 15-3-604 and 15-3-606, which relate to bonds of personal representatives (§ 15-7-304).

Duty to Administer the Trust in an Appropriate Place

A trustee has a continuing duty to administer the trust at a place appropriate to the trust’s purposes and to its sound, efficient management (Idaho Code § 15-7-305). If the principal place of administration becomes inappropriate for any reason, the court may enter any order furthering efficient administration and the beneficiaries’ interests (§ 15-7-305).

If appropriate, such an order may include releasing the registration, removing the trustee, and appointing a trustee in another state (§ 15-7-305). Trust provisions about the place of administration and changes to it control, unless following them would be contrary to efficient administration or the trust’s purposes (§ 15-7-305).

The views of adult beneficiaries must be given weight in deciding whether the trustee and the place of administration are suitable (§ 15-7-305).

Distributing Assets in Kind

Sometimes a trustee satisfies a pecuniary (fixed-dollar) transfer in trust by distributing assets instead of cash, valued at their federal estate tax values. In that case, unless the governing instrument provides otherwise, the trustee must distribute assets, including cash, fairly representative of the appreciation or depreciation in all the property available for that distribution (Idaho Code § 15-1-109(1)).

When Is a Trustee Personally Liable to Others?

Section 15-7-306 separates the trustee’s personal liability from the liability of the trust estate (the property held in the trust). The rules are summarized below.

Type of claim	Is the trustee personally liable?	Idaho Code
Contracts properly entered into as trustee during administration	No, unless the contract provides otherwise, or the trustee failed to reveal the representative capacity and identify the trust estate in the contract	§ 15-7-306(a)
Obligations arising from ownership or control of trust property	Only if the trustee is personally at fault	§ 15-7-306(b)
Torts (wrongful acts causing harm) committed during administration	Only if the trustee is personally at fault	§ 15-7-306(b)

Claims of these types may be asserted against the trust estate by proceeding against the trustee in the trustee’s fiduciary capacity, whether or not the trustee is personally liable (Idaho Code § 15-7-306(c)). The question of liability as between the trust estate and the trustee individually may be decided in a proceeding for accounting, surcharge, or indemnification, or another appropriate proceeding (§ 15-7-306(d)).

Time Limits on Claims for Breach of Trust

Idaho sets time limits on claims against a trustee for breach of trust once a beneficiary receives a final account or statement (Idaho Code § 15-7-307).

The Six-Month Rule

A claim for breach of trust is barred as to a beneficiary who received a final account or other statement that fully disclosed the matter and showed that the trust relationship between the trustee and the beneficiary ended. The claim is barred unless a proceeding to assert it is started within six months after the beneficiary received the final account or statement (Idaho Code § 15-7-307).

The Three-Year Protection

Even without full disclosure, a trustee is protected after three years if the trustee issued a final account or statement that the beneficiary received and informed the beneficiary of the location and availability of records for examination (§ 15-7-307).

When a Beneficiary “Receives” an Account

An adult beneficiary is treated as receiving the final account or statement if it is received personally. For a minor or disabled person, it counts if received by the representative described in section 15-1-403(a)(1) and (2) (§ 15-7-307).

These time limits apply unless the claim was already barred by an earlier court decision, consent, or another limitation (§ 15-7-307).

Court Review of Fees and Hired Help

On petition of an interested person, after notice to all interested persons, the court may review whether the trustee properly hired any person, such as an attorney, auditor, or investment advisor (Idaho Code § 15-7-205). The court may also review whether that person’s pay, and the trustee’s own compensation, are reasonable. Anyone who received excessive compensation from a trust may be ordered to make appropriate refunds (§ 15-7-205).

Removal of a Trustee

A trustee may be removed in keeping with the terms of the trust. The court may also remove a trustee on its own initiative, or on petition of a trustor (the person who created the trust), a co-trustee, or a beneficiary (Idaho Code § 15-7-308(1)).

The court may remove a trustee or order other appropriate relief in these situations (§ 15-7-308(2)):

• The trustee has committed a material breach of trust.
• The trustee is unfit or unable to administer the trust.
• Lack of cooperation among co-trustees substantially impairs administration of the trust.
• The trustee’s investment decisions, even if not a breach of trust, have led to investment performance persistently and substantially below that of comparable trusts.
• Because of changed circumstances, removal would substantially further the trustor’s purpose in creating the trust.
• Other good cause is shown.

While a removal petition is pending, the court may order relief needed to protect the trust property or the beneficiaries’ interests (§ 15-7-308(3)).

A trustee who does not register a trust within 30 days after a written demand by a settlor or beneficiary is also subject to removal and denial of compensation or to surcharge, as the court may direct, with limited exceptions (Idaho Code § 15-7-104).

How I Can Help

I help trustees understand what the Idaho Code expects of them, from the first notice to beneficiaries through final accounts. I also work with beneficiaries who have concerns about how a trust is being run, including requests for information, bond, court review of fees, or removal of a trustee. Request a consultation to discuss your situation.
