N.C. R. Civ. P. 52

(a) Findings. -

(1) In all actions tried upon the facts without a jury or with an advisory jury, the court shall find the facts specially and state separately its conclusions of law thereon and direct the entry of the appropriate judgment.

(2) Findings of fact and conclusions of law are necessary on decisions of any motion or order ex mero motu only when requested by a party and as provided by Rule 41(b). Similarly, findings of fact and conclusions of law are necessary on the granting or denying of a preliminary injunction or any other provisional remedy only when required by statute expressly relating to such remedy or requested by a party.

(3) If an opinion or memorandum of decision is filed, it will be sufficient if the findings of fact and conclusions of law appear therein.

(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.

(c) Review on appeal. - When findings of fact are made in actions tried by the court without a jury, 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 such findings or has made a motion to amend them or a motion for judgment, or a request for specific findings.
