An affidavit executed by the attorney-in-fact under a power of attorney, durable or otherwise, stating that the attorney-in-fact did not have at the time of exercise of the power actual knowledge of the termination of the power by revocation or of the principal's death, disability or incapacity is conclusive proof of the nonrevocation or nontermination of the power at that time with respect to acts taken in good faith reliance upon the affidavit. If the exercise of the power of attorney requires execution and delivery of any instrument that is recordable, the affidavit when authenticated for record is likewise recordable. This section does not affect any provision in a power of attorney for its termination by expiration of time or occurrence of an event other than express revocation or a change in the principal's capacity. [1991, c. 719, §3 (NEW).]
