The collection of a judgment shall not be delayed or hindered, or the lien created by law abate, by reason of the death of any person in whose favor such judgment stands; but the executor or administrator may cause his or her letters of office to be filed in such court, after which the judgment may be enforced and proceeding had in the name of the executor or administrator as such, in the same manner as if the judgment had been recovered in his or her name.
