Trustee (or the holding of a trusteeship) is a legal term which, in its broadest sense, can refer to any person who holds property, authority, or a position of trust or responsibility for the benefit of another. A trustee can also refer to a person who is allowed to do certain tasks but not able to gain income. Although in the strictest sense of the term a trustee is the holder of property on behalf of a beneficiary, the more expansive sense encompasses persons who serve, for example, on the Board of Trustees for an institution that operates for a charity, for the benefit of the general public, or a person in the local government.
A trust can be set up either to benefit particular persons, or for any charitable purposes (but not generally for non-charitable purposes): typical examples are a will trust for the testator's children and family, a pension trust (to confer benefits on employees and their families) and a charitable trust. In all cases, the trustee may be a person or company, whether or not they are a prospective beneficiary.
Trustees have certain duties (some of which are fiduciary). These include the duty to:
The terms of instrument that creates the trust may narrow or expand these duties—but in most instances they cannot be eliminated completely. Corporate trustees, typically trust departments at large banks, often have very narrow duties, limited to those the trust indenture explicitly defines.
A trustee carries the fiduciary responsibility and liability to use the trust assets according to the provisions of the trust instrument (and often regardless of their own or the beneficiaries' wishes). The trustee may find himself liable to claimants, prospective beneficiaries, or third parties. In the event that a trustee incurs a liability (for example, in litigation, or for taxes, or under the terms of a lease) in excess of the trust property they hold, they may find themselves personally liable for the excess.
Trustees are generally held to a "prudent person" standard in regard to meeting their fiduciary responsibilities, though investment, legal, and other professionals can, in some jurisdictions, be held to a higher standard commensurate with their higher expertise.-Trustees can be paid for their time and trouble in performing their duties only if the trust specifically provides for payment. It is common for lawyers to draft will trusts so as to permit such payment, and to take office accordingly: this may be an unnecessary expense for small estates.
