When many people have been wronged by a company, it doesn't always make financial sense for each person to file a separate lawsuit against the business. A class action--which allows many plaintiffs to consolidate similar or identical claims into a single lawsuit--offers advantages to both plaintiffs and defendants. If you've been injured or defrauded by a company and believe that others have had the same experience, talk to a class actions lawyer to learn whether you have grounds for a lawsuit. A class actions attorney can investigate the potential scope and magnitude of a lawsuit, and determine whether another class action lawsuit has already been filed with the courts. If the law firm determines that a class action is appropriate, it can prepare and file the lawsuit on your behalf.
