Except as otherwise provided in this chapter, any bank or trust company shall have power to act in each and every fiduciary capacity permitted by the terms of this article, and as commissioner for the sale of real estate, without bond or other security, and administer oaths attested by the signature of its secretary or cashier and its seal wherever it is acting in any such fiduciary capacity and whenever an individual acting in the same capacity is authorized by law to administer oaths. The court having jurisdiction of the fiduciary at any time, whether before or after acceptance of any fiduciary appointment, may require a bond or other security, and upon failure of such corporation to give a bond or security as required, may remove such corporation and revoke its appointment. No bank or trust company shall pledge or deposit any of its assets as a condition to the exercise of any of its powers as a fiduciary.
