Maryland Estates and Trusts Section 15-207

      If a check is drawn upon the account of his principal in a bank by a fiduciary who is empowered to draw checks upon the account of the principal, the bank is authorized to pay the check without being liable to the principal, unless the bank pays the check with actual knowledge that the fiduciary is committing a breach of his obligation as fiduciary in drawing the check, or with knowledge of the facts that its action in paying the check amounts to bad faith. If, however, the check is payable to the drawee bank and is delivered to it in payment of or as security for a personal debt of the fiduciary to it, the bank is liable to the principal if the fiduciary in fact commits a breach of his obligation as fiduciary in drawing or delivering the check.
