I am having a problem with a business deal that went bad and need to know what legal trouble I may be in for. I was delivering a trailer from California to Wisconson. I was paid $3800 dollars up front for the job, The company paying me wrote the check out to my co-worker, not to me. The co-worker cashed the check and we picked up the trailer. Once on the road the trailer brakes on the customers trailer we noticed did not work, this was a 9,000 pound trailer and was not safe to pull without brakes. We dropped the trailer back off at the same spot we picked it up from, and told the man it was unsafe to tow. Now my question is, do I need to refund him all of his money, or am I entitled to get my expences back, the man who I was doing the job for told me he is pressing criminal charges for grand theft, along with civil charges. Is this grand theft or fraud if I dont refund him all of his money, or is this a civil matter. How do I work it out since he wrote the check out to my partner and not me, what legal trouble do I face.
