Sometimes, in a divorce, a court will decide that custody of the divorcing couple's kids should be shared jointly by both parents. Other times though, a court decides on a custody arrangement in which just one of the parents has custody. When this occurs, the other parent (the noncustodial parent) may have significant concerns regarding what this will mean for their relationship with their children.
One thing it is important for a divorcing parent to note is that, if they are not granted custody of the children, this does not mean they won't be able to have any time with the kids. In fact, time with the kids is something a noncustodial parent generally has the right to. Under Illinois law, barring certain circumstances, reasonable visitation rights in relation to their kids are something noncustodial parents in the state are entitled to.
