Unbelievably Great Experience

5 stars review

I can't recommend People Clerk enough. Camila & crew helped me file suit for a situation that had plagued me for over a year, one in which I felt very wronged and was sure a judge would agree. But there was no way I had the time to learn how to file in small claims court myself.
