Mo. Rev. Stat. § 469.250: Payment or transfers to fiduciaries or at the direction of the fiduciary, effect on transferor.

A person who in good faith pays or transfers to a fiduciary or to any other person as directed by a fiduciary any money or other property which the fiduciary as such is authorized to receive, is not responsible for the proper application thereof by the fiduciary, and any right or title acquired from the fiduciary in consideration of such payment or transfer is not invalid in consequence of a misapplication by the fiduciary.
