Illinois courts operate, with respect to child custody and support matters, much like courts in other states in the sense that the best interests of the child or children are always paramount. In doing so, the court takes into consideration a number of factors to achieve a custody situation that is best for the child when the parents can’t agree. Following are the laws governing Illinois child custody and Illinois child support.

Illinois Child Custody:

Illinois courts will do everything possible to lessen the emotional impact on children of divorcing parents. If the parents cannot agree on custody, the courts will decide on the basis of the best interests of the child and children. It will consider all relevant factors, including the following:
1) wishes of the parents,
2) wishes of the child,
3) child-parent relationship,
4) child’s adjustment to present situation,
5) mental and physical health of all parties,
6) history of physical violence or threats,
7) abuse,
8) parent’s willingness to facilitate child’s relationship with other parent.

Illinois Child Support:

Illinois courts use the Percentage of Income formula to calculate how much a parent must provide for support of the child or children. The court requires a parent to pay a certain percentage of his or her income for child support. The percentage is based on the number of children. For example, a non-custodial parent with one child might be required to pay 20% of his or her net income as child support. In some situations both parents may be required to pay child support.
