If, after exhausting all other remedies in this section, the personal representative cannot reasonably recover a responsible person's liability, then, with the approval of the clerk, the defaulting responsible person's liability shall be apportioned on a pro rata basis among the responsible persons who have not defaulted. Each nondefaulting other responsible person shall be liable for the amount of the liability apportioned to it in the same manner and to the same extent as its original liability for the elective share; provided, that each responsible person's liability shall not exceed the responsible person's proportionate share of the value of the nonspousal assets based on the values used in determining Total Net Assets. Each nondefaulting other responsible person shall be entitled to a proportionate share of any judgment against or subsequent recovery of the liability from the defaulting responsible person.
