Trustee duties are the enforceable obligations that govern trust administration. A trustee is not merely a title holder or asset manager. A trustee is a fiduciary who must administer the trust in good faith, according to the trust terms, for beneficiary interests, and under the standards of loyalty, prudence, impartiality, accounting, disclosure, and preservation.

Trustee duties are not optional. They arise automatically upon acceptance of the trusteeship. A trustee who ignores, violates, or neglects these duties commits a breach of trust, subject to remedies including surcharge, removal, disgorgement, constructive trust, equitable lien, and denial of compensation. Authority without duty discipline creates breach exposure.

A trustee's duties govern the exercise of trustee authority. Authority grants the power to administer; duty controls how that power must be exercised.

No trustee decision should proceed unless the trustee identifies: (1) the duty governing the decision, (2) the trust purpose served, (3) the beneficiary interest affected, (4) the authority source, and (5) the record supporting the action.

• Duty to Administer: The trustee must administer the trust according to its terms, for its purposes, and in the interests of the beneficiaries. This is the foundational duty from which all others derive.
• Duty of Loyalty: The trustee must act solely in the interest of the beneficiaries, avoiding self-dealing, conflicts of interest, and unauthorized personal advantage.
• Duty of Prudence (Care): The trustee must exercise reasonable care, skill, and caution in all trust administration functions, including investment, management, and distribution.
• Duty of Impartiality: If there are multiple beneficiaries or successive interests, the trustee must act impartially, balancing interests according to the trust's purposes.
• Duty to Account: The trustee must maintain accurate records of receipts, disbursements, and transactions, and provide accountings to beneficiaries.
• Duty to Inform and Report: The trustee must keep beneficiaries reasonably informed about trust administration and provide material information upon request.
• Duty to Preserve and Identify Trust Property: The trustee must keep trust property separate from personal property, maintain accurate records, and preserve trust assets.
• Duty to Avoid Commingling: Trust property must not be mixed with the trustee's personal property or other trusts unless expressly authorized.
• Duty to Enforce and Defend Claims: The trustee must take reasonable steps to enforce claims belonging to the trust and defend claims against the trust.
• Duty to Monitor Delegates: When delegating functions, the trustee must exercise reasonable care in selecting agents and supervise their performance.
• Duty to Act in Good Faith: All trustee actions must be taken in good faith, honestly, and with fair dealing.
• Duty to Comply with the Governing Instrument: The trust instrument defines the trustee's duties unless contrary to law. The trustee must know and follow the trust terms.

Clarifications: Trustee duties are not optional. Trustee discretion remains subject to fiduciary review. Trustee authority without duty discipline creates breach exposure. Good intentions do not cure duty violations.

These authorities reflect broadly recognized trustee duty principles. Specific application depends on jurisdiction, trust terms, facts, governing documents, and competent professional review.

• Opening Trust Accounts: The duty to identify trust property requires that accounts be titled in trustee capacity, not individually.
• Maintaining Asset Schedules: The duty to preserve requires accurate records of all trust property, including values and locations.
• Making Distributions: The duty of loyalty and impartiality requires that distributions follow trust terms and treat beneficiaries fairly.
• Paying Expenses: The duty of prudence requires that expenses be reasonable, necessary for administration, and properly documented.
• Investing Trust Property: The duty of prudence (including the Uniform Prudent Investor Act) requires reasonable investment policies considering risk and return.
• Communicating with Beneficiaries: The duty to inform requires regular reports, accountings, and responses to reasonable requests.
• Preparing Accountings: The duty to account requires accurate, complete, and timely financial reports.
• Preserving Records: The duty to identify and preserve property requires organized, accessible, durable records.
• Managing Conflicts: The duty of loyalty requires disclosure of any conflict and, unless authorized, avoidance of conflicted transactions.
• Delegating Functions: The duty to monitor requires careful selection of agents and ongoing supervision.
• Closing Administration: Upon termination, the trustee must provide a final accounting, distribute assets, and preserve records.

• Trust instrument defining duties and powers.
• Trustee acceptance document acknowledging duties.
• Duty checklist for regular administration review.
• Asset inventory (initial and updated).
• Account ledger tracking all receipts and disbursements.
• Beneficiary notice log documenting communications and reports provided.
• Conflict disclosure log documenting any potential or actual conflicts.
• Distribution records with authority reference and basis.
• Investment review records documenting the prudent process.
• Expense approvals with reasonableness analysis.
• Annual accounting (financial statements and activity reports).
• Delegation agreements and monitoring records.
• Meeting minutes and trustee resolutions.
• Final accounting upon termination.

Core rule: Record precedes recognition. Without records demonstrating duty compliance, trustee administration is unverifiable and vulnerable to challenge.

• Treating trustee role as ownership. Legal title is fiduciary title, not personal property. This confusion leads to self-dealing and commingling.
• Failing to read the trust instrument. The trust instrument defines duties. Acting without reading it risks violation of trust terms.
• Making undocumented distributions. Without documentation, distributions cannot be verified, and the trustee may be surcharged.
• Favoring one beneficiary improperly. The duty of impartiality prohibits preference unless authorized by trust terms.
• Failing to account. Beneficiaries have a right to accountings. Failure to account may result in removal and surcharge.
• Commingling trust and personal assets. Commingling violates the duty to separate and may result in loss of trust character.
• Ignoring conflicts. A conflict must be disclosed and properly authorized. Ignoring it breaches loyalty.
• Delegating without oversight. A trustee remains responsible for delegated functions and must monitor agents.
• Assuming good intentions cure defective records. Good faith without documentation is insufficient. Records are required.

KLI teaches trustee duties because trustee authority must be restrained by fiduciary accountability. Trust administration depends on duty discipline, record integrity, and equitable review. The trustee's office is preserved by proper administration, not personal control. Duties ensure that authority serves the trust's purposes and beneficiaries' interests, not the trustee's convenience. Without duty discipline, trust administration loses reliability, and beneficiaries lose protection.
