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

When any grant is revoked, all payments and dispositions made in good faith to a personal representative under it before the revocation are a valid discharge to the person making them; and the personal representative who acted under the revoked grant may retain and reimburse himself in respect of any payments or dispositions made by him which the person to whom a grant is afterwards made might have properly made.

This Article has effect only in relation to the estates of persons dying after the end of the year 1971.
