Civil orders and judgments frequently are not entered immediately upon the conclusion of an evidentiary trial or hearing; judges often need time to consider complicated or extensive evidence to decide how to rule, and civil orders and judgments frequently require extensive findings of fact and conclusions of law which take time to reduce to writing. Regardless of what a trial judge may say at the end of an evidentiary trial or hearing, a civil order or judgment is not entered until it is reduced to writing, signed by the judge, and filed with the clerk of court. GS 1A, Rule 58.
