In all cases where a claim of lien is recorded for labor, services, equipment, or materials furnished to any contractor, he shall defend any action brought thereon at his own expense, and during the pendency of such action the owner may withhold from the original contractor the amount of money for which the claim of lien is recorded. In case of judgment in such action against the owner or his property upon the lien, the owner shall be entitled to deduct from any amount then or thereafter due from him to the original contractor the amount of such judgment and costs. If the amount of such judgment and costs exceeds the amount due from him to the original contractor, or if he has settled with the original contractor in full, he shall be entitled to recover back from the original contractor, or the sureties on any bond given by him for the faithful performance of his contract, any amount of such judgment and costs in excess of the contract price, and for which the original contractor was originally the party liable.
