Frequently Asked Questions

  • Many companies' contracts take away your right to sue in court. They require you to instead go to arbitration, which happens in a private setting through one of a few arbitration companies. In many cases, this means people don't pursue their rights because it is too inefficient. We are pioneers in Mass Arbitration, where we remove the inefficiency by introducing automation and economies of scale to get justice even where you can't go to court.

  • Put simply, it's a group of similar or related cases that tend to arise from the same dangerous product, drug, or environmental condition. It occurs in traditional courts, but it differs from a class action in that every person who wants to be involved has to come forward and participate individually, usually by hiring a lawyer. In a class action, most people can sit back and file a claim if the case is successful.

  • Not anymore! In December of 2023, Senate Bill 410 was signed into law and Michigan finally got rid of its tragic status as the only place where people who were harmed by a dangerous drug couldn't sue for their injuries. Michiganders now have rights similar to our fellow Americans in the other 49 states.

  • We're proud to investigate and prosecute cases that aren't always obvious. We got into this business to help regular people and punish bad corporations that harm them. Often there are overlooked sources of law that can help with that mission.

  • Never, ever. We only get paid if you get paid, and our fees are either a portion of your recovery, or in some cases paid by the defendant directly. This means we only take cases we believe in, because we try not to work for free unless we're giving our time pro bono (which we do, proudly).
