A trustee is not liable to any person for giving or failing to give notice under this section.(b)

A potential contestant has notified the trustee of a possible judicial proceeding to contest the trust and a judicial proceeding is commenced within sixty days after the contestant sent the notification.(3)
Unless a distribution or payment no longer can be questioned because of adjudication, estoppel, or limitation, a beneficiary of a trust that is determined to have been invalid, or a distributee of property improperly distributed or paid, or a claimant who is improperly paid, is liable for the return of the property improperly received and its income, if any, since the distribution, if he or she has the property. If he or she does not have the property, then he or she is liable for the return of the value as of the date of his or her disposition of the property improperly received, and its income and gain, if any received by him or her.
