Domestic, or Family Law, is the body of law governing Marriage, Dissolution of Marriage (Divorce), Paternity, Child Support, Child Custody, Visitation, Maintenance, and many other areas that control the relationship between husbands, wifes, partners, children and grandparents. Domestic/Family Law is made up of hundreds of statutes, regulations, and precednts that control the courts, families and lawyers.
Divorce and family law changed mightily in 2017 with the implementation of the new Illinois Marriage and Dissolution of Marriage Act. I can't go into all of the different changes; however, I can tell you that with the change in law the certainty that many lawyers, Including myself, had about the way in which certain cases would proceed have to be changed. We simply don't know what the courts will do in all the new situations.
To complicate matters, in the summer of 2017 a change in the manner in which child support is calcuulated became the law. What was once a very simple, but perhaps unfair, system is now a very complicated system which may still be unfair. Again, because the laws so new lawyer such as myself are not quite sure what the courts will do in many situations.
