Separation. Ask 20 different (non-lawyer) people what it means or who needs it, and you will likely get 20 different answers. In the context of obtaining a legal separation under Illinois law, it is similar to a divorce but it isn't. I meet with many people who request a legal separation who really mean something else or are confused about what it will and won't accomplish. If you are having problems in your marriage and are considering a separation or want to know the difference between separation and divorce under Illinois law, sit down and talk to an attorney. At O'Connor Cadiz Law, we do offer legal separations and encourage you to come in to discuss your situation, get the facts, and get your questions answered.
