Rule 52. Findings by the Court; Judgment on Partial Findings

(a) Effect. In all actions tried upon the facts, the court shall find the facts specially and state separately its conclusions of law thereon, and judgment shall be entered pursuant to Rule 58; and in granting or refusing interlocutory injunctions the court shall similarly set forth the findings of fact and conclusions of law which constitute the grounds of its action. Requests for findings are not necessary for purposes of review. Findings of fact, whether based on oral or documentary evidence, 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. It will be sufficient if the findings of fact and conclusions of law are stated orally and recorded in open court following the close of the evidence or appear in an opinion or memorandum of decision filed by the court. Findings of fact and conclusions of law are unnecessary on decisions of motions under Rule 12 or 56 or any other motion except as provided in subdivision (c) of this rule.

(b) Amendment. Upon motion of a party made not later than 10 days after entry of judgment, the court may amend its findings or make additional findings and may amend the judgment accordingly. The motion may be made with a motion for a new trial pursuant to Rule 59. The question of the sufficiency of the evidence to support the findings may be raised whether or not the party raising the question has made in the court an objection to such findings or has made a motion to amend them or a motion for judgment.

(c) Judgment on Partial Findings. If during a trial a party has been fully heard with respect to an issue and the court finds against the party on that issue, the court may enter judgment as a matter of law against that party on any claim, counterclaim, cross-claim or third-party claim that cannot under the controlling law be maintained or defeated without a favorable finding on that issue, or the court may decline to render any judgment until the close of all the evidence. Such a judgment shall be supported by findings of fact and conclusions of law as required by subdivision (a) of this rule.
