The interrogatories shall be served simultaneously with the summons and writ of garnishment.
The garnishee shall file and serve verified answers to the interrogatories on the garnishor during the ten days immediately after the return date of the writ or, in the case of a continuous wage garnishment, within 20 days from the date on which the garnishee is served with the writ.
The garnishee’s answers to interrogatories are conclusively binding against the garnishor if the garnishor does not timely file exceptions to the interrogatory answers.
