If parents have a custody dispute, they may need guidance through a court order. In Arkansas, custody laws require a review by a judge when the parents cannot agree on custody. Not surprisingly, some parents might begin dating other people while they have custody disputes or share co-parenting duties. A parent's new relationship and cohabitation might affect a judge's decision in the initial custody dispute or in the modification of an existing custody order. Arkansas custody laws determine the legal standard to be applied — the best interests of the child — when parents have custody disputes. State laws specifically allow a judge to look at each parent's moral character and judgment when deciding how to rule regarding custody.
