If an order appointing a fiduciary is reversed on appeal for error, all acts of the fiduciary performed after issuance of letters and prior to the reversal are as valid as though the order were affirmed and the person appointed is not liable for any otherwise proper act done in good faith before the reversal, nor is any transaction void by reason of the reversal if entered into with a third person dealing in good faith and for value.
