The fifth-largest state in the U.S., Illinois is home to nearly 13 million people, almost 3 million in Chicago alone. With more than 60,000 attorneys in the state, it can be difficult for individuals considering their legal options to select the best attorney for their class action lawsuit. Making sure you have the right team on your side is crucial, especially when going up against a major corporation or other huge organization, which is common in class action cases.
If you’ve been injured, defrauded, or suffered any other type of loss and believe you may be eligible for compensation as part of a class action lawsuit, consider contacting one of the law offices or attorneys on this list. You will typically be able to receive a free evaluation of your case, and with most class action lawsuits, attorneys only get paid if you win your claim.
