A trial court in a support modification may use a previously-used income figure when it finds no credible evidence of changed income; and may use the sole custody guidelines when a father does not prove that he is exercising his court-ordered parenting time that would otherwise justify the shared-custody guidelines; but may not decide to use a higher income figure without citing any evidence that it was the father's income or his earning capacity, the Va. Court of Appeals rules in Hatcher v. Matthews, unpublished, 9/5/17. The father had been found non-credible in earlier child support proceedings, and did not present evidence to document his claims, and this justified deference to the trial court's discretionary decision not to simply take him at his word.
