(2) The missing person may recover from distributees any property of the missing person’s estate that is in their possession, or the value of distributions received by them, to the extent that recovery from distributees is equitable in view of all the circumstances, but an action under this paragraph is forever barred five years after the time the distribution was made.

(b) The remedies available to the missing person under subdivision (a) are exclusive, except for any remedy the missing person may have by reason of fraud or intentional wrongdoing.
