(1) Every person making or permitting to be made any payment or disposition in good faith under a representation shall be indemnified and protected in so doing, notwithstanding any defect or circumstance whatsoever affecting the validity of the representation.

(2) Where a representation is revoked, all payments and dispositions made in good faith to a personal representative under the representation before the revocation thereof are a valid discharge to the person making the same; and the personal representative who acted under the revoked representation may retain and reimburse himself in respect of any payments or dispositions made by him which the person to whom representation is afterwards granted might have properly made.
