(a) When a garnishee fails or refuses to file a garnishee answer at least once every 45 days, such garnishee shall automatically be in default. The default may be opened as provided in Code Section 18-4-21. If the case is still in default after the expiration of the period of 15 days, judgment by default may be entered at any time thereafter against such garnishee for the amount remaining due on the judgment obtained against the defendant as shown in the plaintiffs affidavit of continuing garnishment.
(b) A garnishee may obtain relief from a default judgment upon the same conditions as provided in Code Section 18-4-24.
