Ala. Code § 19-1-10

When a deposit is made in a bank in the name of two or more persons as fiduciaries and a check is drawn upon the trust account by any fiduciary or fiduciaries authorized by the other fiduciary or fiduciaries to draw checks upon the trust account, neither the payee nor other holder nor the bank is bound to inquire whether it is a breach of trust to authorize such fiduciary or fiduciaries to draw checks upon the trust account, and is not liable unless the circumstances be such that the action of the payee or other holder or the bank amounts to bad faith.
