Where a declaration or other pleading alleges that any person made, indorsed, assigned or accepted any writing, it shall not be necessary to prove such fact unless the pleading which puts the matter in issue be verified, or there be an affidavit filed therewith denying such fact.

In any action, suit or proceeding upon, or to enforce, or in which is set off, a judgment or decree, foreign or domestic, wherein the recovery of such judgment or decree is alleged in any pleading, it shall not be necessary to prove the entry or genuineness of such judgment or decree, unless the pleading which puts the matter in issue be verified, or there be an affidavit filed therewith denying such entry or genuineness.
