- Trustees are usually appointed by the settlor or testator, and if none are appointed then the court will appoint one. The settlor may also appoint other people to appoint new trustees when needed. - A minor or infant cannot be a trustee. When appointed, the property vests in the trustees until they die, retire, or are removed. Trusteeship terminates upon disclaimer, death, retirement, or removal of a trustee. The court also has powers to appoint or remove trustees if needed.
