Trustee Duties and Responsibilities

A trustee is a fiduciary — legally bound to act in the beneficiaries' best interests. Understanding these duties is essential whether you're naming a trustee or serving as one.

The Core Fiduciary Duties

1. Duty of Loyalty

The trustee must act solely in the beneficiaries' interests. They cannot use trust assets for personal benefit, accept undisclosed compensation, or engage in self-dealing. Any conflict of interest must be disclosed. A trustee who profits from their position must account for and return those profits.

2. Duty of Prudence (Prudent Investor Rule)

The trustee must invest and manage trust assets as a prudent person would. Most states follow the Uniform Prudent Investor Act, which requires:

  • Considering the trust's purposes, distribution requirements, and tax implications
  • Diversifying investments (unless the trustee reasonably determines diversification would be detrimental)
  • Evaluating investments as part of the overall portfolio, not individually
  • Considering both risk and return

3. Duty of Impartiality

When there are multiple beneficiaries, the trustee must treat them fairly according to the trust terms. This doesn't mean equal treatment — it means following the trust's instructions without favoritism. Income beneficiaries and remainder beneficiaries often have competing interests, and the trustee must balance them.

4. Duty to Inform and Account

The trustee must keep beneficiaries informed about trust administration. This includes:

  • Providing an annual accounting of trust assets, income, expenses, and distributions
  • Notifying beneficiaries of the trust's existence and their interests
  • Responding to reasonable requests for information about the trust
  • Providing copies of the trust agreement when required by state law

5. Duty to Preserve and Protect Trust Property

The trustee must take reasonable steps to protect trust assets — maintaining insurance, securing property, collecting income, and addressing risks. Negligence in protecting trust property can result in personal liability.

6. Duty Not to Delegate (with exceptions)

The trustee must personally perform their duties. However, they can delegate functions that require specialized expertise (investment management, tax preparation, legal work) — provided they exercise reasonable care in selecting and monitoring the delegate.

7. Duty to Enforce and Defend Claims

The trustee must take reasonable steps to enforce claims on behalf of the trust and defend claims against the trust. Sitting on a valid claim or failing to defend a lawsuit can result in liability.

What Happens When a Trustee Breaches Their Duties?

A breach of fiduciary duty can result in:

  • Personal liability — the trustee may have to repay losses from their own funds
  • Removal — a court can remove the trustee and appoint a successor
  • Surcharge — the trustee may be ordered to pay damages or forfeit fees
  • Criminal charges — in cases of fraud or embezzlement

Beneficiaries can petition the court to compel an accounting, surcharge the trustee, or remove them. Most states have statutes of limitations on trust claims — typically 1-3 years from when the beneficiary discovered (or should have discovered) the breach.

Practical Tips for Trustees

  • Keep meticulous records of every transaction
  • Never commingle trust assets with personal assets
  • Document all decisions and the reasoning behind them
  • Communicate regularly with beneficiaries
  • Get professional help when needed (accountant, attorney, investment advisor)
  • Review the trust agreement carefully — it governs everything
