A trustee is a person who receives the power to control beneficiaries’ access to assets under conditions determined by the grantor. Many types of trustees exist, but the most common is a fiduciary. As a fiduciary trustee, you work specifically with finances, such as a trust fund set up by a relative. The legal powers of a trustee are analogous to the power of attorney, but for financial matters only in the case of a trust fund, house deeds, or other assets of the deceased. A trustee position is not something to be taken lightly; you carry the explicit trust of another person or organization.
