A. For purposes of determining child support, shared custody is defined as a parent's visiting with the child for 123 or more overnights a year. Shared custody will result in a different amount of child support than in a sole custody situation.
With sole custody, one parent gets legal and physical custody of a child. In a joint custody situation, both parents share legal and physical child custody. In Florida, joint custody is called shared parental responsibility, and both parents must approve all decisions related to the child.
