This is regarding a judgement in the state of California. I received a letter regarding being added to an amended judgement that was against a company I previously worked for. I only worked for the company for less than 2 of the 5 months the plaintiff claims the activities took place and was in training 3,000 miles away during that time. I had no knowledge of the activites the company was involved in. How do I appeal this and do I need an attorney in my current state or the state of California?
