Except as provided in RCW 6.40.040, a foreign judgment meeting the requirements of RCW 6.40.020 is conclusive between the parties to the extent that it grants or denies recovery of a sum of money. The foreign judgment is enforceable in the same manner as the judgment of a sister state which is entitled to full faith and credit.
