An appellate court will not interfere with a trial court's findings of fact unless there is demonstrable and material misdirection, and the recorded evidence shows the findings to be clearly wrong. In adultery damages claims, knowledge of marital status can be inferred from the totality of circumstances and probabilities, including the duration of the relationship, observable indicators (such as wedding rings), the nature of interactions, community size, and inconsistencies in the defendant's behavior. An appellate court should not interfere with an award of damages unless there is a striking disparity between its estimate and that of the trial court, and an unusual degree of certainty that the trial court's estimate is wrong. Adultery damages are properly awarded where the defendant's adulterous relationship caused emotional stress, loss of intimacy, and damage to the marriage.
