Ethel Cain Ladd and Another v. Ernest

Judgment -- foreign judgment -- enforcement by courts of sister state. 1. So long as a judgment payable in installments is absolute in its terms and remains unmodified, or at least until an application
for modification has been made, it is final as to installments which have accrued and is entitled to full faith and credit
in the courts of a sister state in an action founded upon it.
