On appeal of claims tried by the court without a jury or with an advisory jury, at law or in equity, the court on appeal shall not set aside the findings or judgment unless clearly erroneous, and due regard shall be given to the opportunity of the trial court to judge the credibility of the witnesses. The findings of a master, and answers to questions or interrogatories submitted to the jury shall be considered as findings of the court to the extent that the court adopts them. If an opinion or memorandum of decision is filed, it will be sufficient if the findings of fact and conclusions appear therein. Findings of fact are unnecessary on decisions of motions under Rules 12 or 56 or any other motion except as provided in Rule 41(B) (dismissal) and 59(J) (motion to correct errors).
The court's failure to find upon a material issue upon which a finding of fact is required by this subdivision or this rule shall not be resolved by any presumption and may be challenged under subdivision (B) of this rule; but findings of fact with respect to issues upon which findings are not required shall be recognized as findings only upon the issues or matters covered thereby and the judgment or general finding, if any, shall control as to the other issues or matters which are not covered by such findings.
