R.I. Gen. Laws § 19-9-13: Checks of trustees.

When a deposit is made in a regulated institution in the name of two (2) or more persons as trustees, and a check is drawn upon the trust account by any trustee or trustees authorized by the other trustee or trustees to draw checks upon the trust account, neither the payee, nor the other holder, nor the bank is bound to inquire whether it is a breach of trust to authorize the trustee or trustees to draw checks upon the trust account, and the payee, or other holder, or the regulated institution is not liable unless the action of the payee or other holder or the regulated institution amounts to bad faith.
