As administrator acting under appointment of the register of wills or probate court, it performs similar duties, distributing the estate in accordance with decedent's will if there is one, or if there is none, in accordance with the intestate laws of the state, which specify the order of succession and distributive shares in the case of estates of decedents leaving no wills. There are different kinds of administrators, in any of which capacities a trust company may be called upon to act. As trustee under will, the trust company carries out the provisions of the will, investing and managing the estate or particular fund in accordance with the directions of the testator. As such it may hold real and personal property. As trustee under deed or private agreement, a contract is entered into between the company and the owner of the property, by which the title to the property is vested in the corporation subject to the terms recited in the instrument. Such deeds of trust may be revocable or irrevocable. Marriage settlements are frequently made in this way. The trustee's duty in investing the funds is a double one; namely, to invest them securely so that the principal shall be preserved intact, and to invest them as productively as possible under his powers, so that they shall yield the best rate of interest obtainable for the benefit of the person or persons entitled to the income. He must hold the scales evenly, regarding scrupulously his duties to all beneficiaries. The popular idea that security is the only consideration is erroneous, as the trustee is equally bound to invest the funds as profitably as possible and cannot neglect one duty more than the other. The mistaken impression that the corporate trustee, even more than the individual, is mindful only of the safety of the principal and entirely loses sight of the question of income, has arisen from the restrictions as to investments imposed by law, and frequently also by the will or trust deed, and from the fact that the individual executor or trustee, rightly or wrongly, sometimes assumes risks and personal liability which the proper rules of a trust company would not permit it to assume. The executor or trustee is governed, as to the kinds of investments, by the directions of the will or deed of trust. This may require the purchase of "legal investments" only, or state that the trustee is not to be confined to securities prescribed by law, or give specific directions as to the classes of securities which are to be bought. The terms of such documents are always strictly construed by the courts; if no directions are given, the trustee is expected to buy only "legal" securities, and when he exceeds his powers he is held responsible for any loss. Administrators and guardians without broader powers given by will are obliged to invest, except at their personal risk, in such securities as are sanctioned by law or directed by the court.
