Section 14. (a) If a judgment is rendered for the plaintiff by a court in an action founded on a judgment rendered by a court outside of the commonwealth, execution shall not issue until the plaintiff files with the court rendering the judgment in the later action a transcript of the record of the judgment in the earlier case under the seal of the court rendering it, attested by the clerk of such court.
