Nicole Aquino Williamson v. Paul Landon Lamm

This case involves the modification of a permanent parenting plan under which the parents exercised equal parenting time. The mother, who was designated the primary residential parent in the original plan, filed a petition to modify and alleged a material change had occurred in that the child had reached school age and the distance between the parents made the parenting schedule unworkable. The father did not file a counter-petition but filed a competing parenting plan. After a hearing, the trial court changed the primary residential parent for the upcoming school year to the father, established a new residential parenting schedule, and invited the mother to file a new modification petition for the following school year. The mother appealed. We conclude the preponderance of the evidence does not establish a material change in circumstance sufficient to modify the primary residential parent but does establish a material change sufficient to meet the lower standard for modification of the residential parenting schedule. Consequently, we reverse the decision of the trial court and remand for a determination of a residential parenting schedule that is in the best interest of the child.
