A:The court may give one parent primary physical custody or may split custody between the parents. The standard is the “best interest of the child,” which requires consideration of many factors, including the parental duties performed by each parent; stability and continuity for the child; sibling relationships; the child’s well-reasoned preference; which parent is more likely to provide for the child’s physical, emotional, developmental, educational, and special needs; and many other factors. In fact, the court may consider any factor it deems relevant to the case, which makes custody a highly fact-specific determination.
