Title 18, Chapter 4, Section 134
(a) If the amount claimed as original arrearage as of the date of the making of the plaintiff's affidavit is not satisfied by the money payable into court under the initial answer of the garnishee, after application of the funds as set forth in subsection (c) of Code Section 18-4-133, the garnishee shall file further answers no later than 45 days after the previous answer date, stating the earnings accrued and the basis of their accrual and tendering such money accruing in such answer period. The amounts paid into court pursuant to subsequent answers, over and above the periodic payment accruing within such answer period, shall be applied to the original arrearage until the same is retired.
(b) If the earnings paid into court pursuant to any answer by the
garnishee are less than the sums due under the periodic support
requirement accruing over the same period of time, after allowance
for any costs deductible from same, the resulting difference shall
be added to the amount due as original arrearage until the same is
retired by subsequent payments.
(c) The garnishee shall file additional answers until the original
arrearage is retired and all periodic support payments are current.
(d) Upon the termination of employment of the defendant by the
garnishee, the garnishee shall be required to file a final answer
stating the date and reason for the defendant's termination from
employment and stating, to the best of the garnishee's information,
the defendant's present residential address and employer.
