In This TopicIdaho TrustsTopic 12 of 14: Fiduciaries and Banks

Trustees, conservators, personal representatives, agents, and other fiduciaries regularly deposit checks, write checks, and buy or sell stock for the people they serve. Several Idaho statutes in Title 68 set out when banks, people who receive payments, and companies that transfer securities are protected when they deal with a fiduciary, and when they can be held liable if the fiduciary misuses the money (Idaho Code §§ 68-301 through 68-315, 68-601 through 68-603, 68-701 through 68-703, 68-901 through 68-911).

A fiduciary is a person who holds or manages property for someone else and owes that person duties of trust. This page covers four short acts: the Uniform Fiduciaries Law, the Nominee Registration Act, the Uniform Common Trust Fund Act, and the Uniform Act for the Simplification of Fiduciary Security Transfers (Idaho Code §§ 68-314, 68-603, 68-703, 68-911).

The Uniform Fiduciaries Law

Chapter 3 of Title 68 is the Uniform Fiduciaries Law (Idaho Code § 68-314). Most of its sections say when a person or bank dealing with a fiduciary is protected, and when it can be liable to the principal (Idaho Code §§ 68-302 through 68-310).

Key Terms

• Fiduciary includes a trustee under any trust (expressed, implied, resulting, or constructive), executor, administrator, guardian, conservator, curator, receiver, trustee in bankruptcy, assignee for the benefit of creditors, partner, agent, officer of a public or private corporation, public officer, or any other person acting in a fiduciary capacity (Idaho Code § 68-301(1)).
• Principal includes any person to whom a fiduciary owes an obligation (§ 68-301(1)). This is the person or estate the fiduciary serves.
• Bank includes any person or association, incorporated or not, carrying on the business of banking (§ 68-301(1)).
• Good faith: a thing is done in good faith when it is in fact done honestly, “whether it be done negligently or not” (§ 68-301(2)).

Paying Money to a Fiduciary

A person who in good faith pays or transfers money or other property to a fiduciary who is authorized to receive it is not responsible for how the fiduciary uses it (Idaho Code § 68-302). Any right or title acquired from the fiduciary in exchange for that payment is not invalid because the fiduciary later misapplies the money (§ 68-302).

Checks, Deposits, and Negotiable Instruments

The general pattern is the same across several situations. The bank or other person is not required to ask whether the fiduciary is committing a breach. It is protected unless it acts with actual knowledge of the breach, or with knowledge of facts that make its action amount to bad faith. But in several situations, including when the instrument is used to pay the fiduciary’s own personal debt, the other party is liable to the principal if the fiduciary in fact commits a breach (Idaho Code §§ 68-304 through 68-310).

Situation	General rule	When the other party is liable to the principal	Idaho Code
Fiduciary indorses (signs over) a negotiable instrument payable to the fiduciary or the principal	Indorsee need not inquire whether the fiduciary is committing a breach	Actual knowledge of breach or bad faith; or transferred for the fiduciary’s personal debt, or for the fiduciary’s known personal benefit, and the fiduciary in fact breaches	§ 68-304
Fiduciary writes a check payable to a third person	Payee need not inquire	Actual knowledge of breach or bad faith; or check paid to the fiduciary’s personal creditor for a personal debt, or for the fiduciary’s known personal benefit, and the fiduciary in fact breaches	§ 68-305
Fiduciary writes a check payable to himself personally, then transfers it	Transferee need not inquire, even if used for a personal debt	Only with actual knowledge of facts that make taking it bad faith	§ 68-306
Bank pays checks on an account in the fiduciary’s name as fiduciary	Bank may pay without liability to the principal	Actual knowledge of breach or bad faith; or check payable to the bank for the fiduciary’s personal debt to the bank, and the fiduciary in fact breaches	§ 68-307
Fiduciary writes checks on the principal’s own account	Bank may pay without liability to the principal	Actual knowledge of breach or bad faith; or check payable to the bank for the fiduciary’s personal debt to the bank, and the fiduciary in fact breaches	§ 68-308
Fiduciary deposits fiduciary funds into his own personal account	Bank need not inquire and may pay the fiduciary’s personal checks	Actual knowledge of breach in making the deposit or drawing the check, or bad faith	§ 68-309
Account in the names of two or more trustees; one trustee authorized by the others writes a check	Payee, holder, and bank need not inquire whether authorizing that trustee was a breach of trust	Only if their action amounts to bad faith	§ 68-310

A trustee’s own duties and liabilities are covered on the trustee duties and liabilities page.

Limits of the Chapter

• The chapter does not apply to transactions that took place before it took effect (Idaho Code § 68-311).
• In any case the chapter does not cover, the rules of law and equity continue to apply, including the law merchant and the rules relating to trusts, agency, negotiable instruments, and banking (Idaho Code § 68-312).

Holding Trust Assets in a Nominee’s Name

A nominee is a person or entity that holds legal title to property in its name on behalf of someone else. Under the Nominee Registration Act, a bank or trust company acting as a fiduciary may hold a bond, stock, mortgage, deed, or other security or asset (real or personal, including a fractional interest) in the name of its nominee, without mentioning the fiduciary relationship (Idaho Code § 68-601).

If the bank or trust company serves jointly with one or more individual fiduciaries, it needs their consent, and they are authorized to give it (§ 68-601). The statute also has these conditions and rules (§ 68-601):

• The trust company’s records, and all reports or accounts about the fiduciary relationship, must clearly show that the bank or trust company owns the property.
• The nominee must indorse in blank, or sign a conveyance or assignment to the bank or trust company, for each item held in its name.
• The bank or trust company is responsible for the nominee’s acts regarding property held in the nominee’s name.

A corporation and its transfer agent have no obligation to inquire into whether a transfer of stock or securities held in a nominee’s name is proper, unless they have actual knowledge of a breach of fiduciary duty involving those assets (Idaho Code § 68-602).

Separately, the Uniform Trustees’ Powers Act gives a trustee, unless limited in the trust instrument, the power to hold a security in the name of a nominee or in other form without disclosure of the trust, with the trustee liable for any act of the nominee regarding stock held that way (Idaho Code §§ 68-105(a), 68-106(c)(16)). See the trustee powers page.

Common Trust Funds

Under the Uniform Common Trust Fund Act, any state or national bank or trust company qualified to act as a fiduciary in Idaho may establish common trust funds to furnish investments to itself as fiduciary, to an affiliated bank or trust company as fiduciary, or to itself or an affiliate and others as co-fiduciaries (Idaho Code § 68-701(1)).

It may invest funds it lawfully holds for investment in interests in those funds, subject to two conditions (§ 68-701(1)):

• The investment is not prohibited by the instrument, judgment, decree, or order that created the fiduciary relationship.
• If there are co-fiduciaries, the bank or trust company gets their consent.

Two or more banks or trust companies are “affiliated” if they are members of the same affiliated group under section 1504 of the federal Internal Revenue Code, whether or not the affiliate’s main place of business is in Idaho (Idaho Code § 68-701(2)). The content of that federal law is outside this overview.

Transferring Securities Held by a Fiduciary

The Uniform Act for the Simplification of Fiduciary Security Transfers makes it easier for a fiduciary to register and transfer stock, bonds, and similar securities (Idaho Code § 68-911). For this act, “fiduciary” means an executor, administrator, trustee, guardian, committee, conservator, curator, tutor, custodian, or nominee (Idaho Code § 68-901(d)). A “transfer” is a change in registered ownership on the corporation’s books (§ 68-901(g)).

Registering a Security in a Fiduciary’s Name

A corporation or transfer agent registering a security in the name of a fiduciary need not inquire into the existence, extent, or correct description of the fiduciary relationship (Idaho Code § 68-902). It may then assume the new owner continues to be the fiduciary until it receives written notice that the fiduciary is no longer acting as such for that security (§ 68-902).

When a Fiduciary Signs Over a Security

Except as the act otherwise provides, a corporation or transfer agent making a transfer based on a fiduciary’s assignment (a stock power, bond power, deed, or other transfer document) (Idaho Code §§ 68-901(a), 68-903):

• May assume without inquiry that the assignment, even to the fiduciary himself or his nominee, is within his authority and is not a breach of his fiduciary duties.
• May assume without inquiry that the fiduciary complied with any controlling instrument and the governing law, including any law requiring court approval of the transfer.
• Is not charged with notice of, and need not obtain or examine, any court record or document about the fiduciary relationship or the assignment, even if it has the record or document.

Proof of Appointment When the Fiduciary Is Not the Registered Owner

If the fiduciary signing the assignment is not the registered owner, the corporation or transfer agent must obtain evidence of the fiduciary’s appointment or incumbency (Idaho Code § 68-904):

Type of fiduciary	Evidence required	Idaho Code
Appointed or qualified by a court	A certificate issued by or under the direction or supervision of that court or its officer, dated within 60 days before the transfer	§ 68-904(a)
Any other case	A copy of a document showing the appointment, or a certificate from a person reasonably believed to be responsible; if neither, other evidence reasonably deemed appropriate	§ 68-904(b)

Corporations and transfer agents may adopt standards for this evidence, as long as the standards are not manifestly unreasonable (§ 68-904(b)). For a trust, the certification of trust page explains another way a trustee can prove the trust exists.

Objecting to a Transfer: Adverse Claims

A beneficiary, heir, ward, or other person claiming a beneficial interest who objects to a fiduciary’s transfer may give the corporation or transfer agent written notice of the claim (Idaho Code §§ 68-901(b), 68-905(a)). The notice counts only if it (§ 68-905(a)):

• Identifies the claimant, the registered owner, and the issue the security belongs to.
• Gives an address for communications to the claimant.
• Is received before the transfer.

After a security is presented for transfer, a corporation or transfer agent that has received a proper notice may send notice of the presentation by registered or certified mail to the claimant at the address given (Idaho Code § 68-905(b)). If it does, it must withhold the transfer for 30 days after mailing, and then make the transfer unless restrained by a court order (§ 68-905(b)).

Who Is Protected

• A corporation or transfer agent incurs no liability to any person by making a transfer or otherwise acting as the act authorizes (Idaho Code § 68-906).
• A person who participates in acquiring, disposing of, or transferring a security by or to a fiduciary, including someone who guarantees the fiduciary’s signature, is not liable for participating in a breach because of failure to inquire, unless it is shown the person acted with actual knowledge that the proceeds were being or would be used wrongfully for the fiduciary’s own benefit, or that the transaction was otherwise a breach of duty (Idaho Code § 68-907(a)).
• A signature guarantor is not liable on the guarantee to anyone to whom the corporation or transfer agent has no liability under the act (§ 68-907(b)).

Which Law Applies

A corporation’s and its transfer agents’ rights and duties in registering or transferring a security for a fiduciary are governed by the law of the place where the corporation is organized (Idaho Code § 68-908(a)). The act governs other persons’ acts in Idaho, and signature guarantees given in Idaho (§ 68-908(b)). It does not affect a corporation’s or transfer agent’s obligations for estate, inheritance, succession, or other Idaho taxes (Idaho Code § 68-909).

How I Can Help

I help trustees, conservators, and personal representatives understand what banks and transfer agents may require when they move accounts or securities, and I help beneficiaries and heirs who believe a fiduciary is misusing funds consider options such as notifying a transfer agent of an adverse claim.
