Georgia Code Title 9. Civil Practice § 9-11-52

(a) In ruling on interlocutory injunctions and in all nonjury trials in courts of record, the court shall upon request of any party made prior to such ruling, find the facts specially and shall state separately its conclusions of law. If an opinion or memorandum of decision is filed, it will be sufficient if the findings and conclusions appear therein. Findings shall not be set aside unless clearly erroneous, and due regard shall be given to the opportunity of the trial court to judge the credibility of the witnesses.

(b) This Code section shall not apply to actions involving uncontested divorce, alimony, and custody of minors, nor to motions except as provided in subsection (b) of Code Section 9-11-41. The requirements of subsection (a) of this Code section may be waived in writing or on the record by the parties.

(c) Upon motion made not later than 20 days after entry of judgment, the court may make or amend its findings or make additional findings and may amend the judgment accordingly. If the motion is made with a motion for new trial, both motions shall be made within 20 days after entry of judgment. The question of the sufficiency of the evidence to support the findings may be raised on appeal whether or not the party raising the question has made in the trial court an objection to findings or a motion for judgment. When findings or conclusions are not made prior to judgment to the extent necessary for review, failure of the losing party to move therefor after judgment shall constitute a waiver of any ground of appeal which requires consideration thereof.
