A judgment for the recovery of money against an executor, administrator or guardian, as such, shall state that it is to be paid in the due course of administration. No execution shall issue thereon, but it shall be certified to the county court, sitting in matters of probate, to be there enforced in accordance with law, but judgment against an executor appointed and acting under a will dispensing with the action of the county court in reference to such estate shall be enforced against the property of the testator in the hands of such executor, by execution, as in other cases.
