A former employer of mine is accusing me of embezzlement. I did the payroll, and he is claiming that I paid myself more than authorized. The amount he claims I now must pay back is $20,000. We never had any written agreement as to to how I would make every week. I paid myself what I would have charged at any other job. I worked for him for over a year and he has just know came after me for the money. He claims he never noticed until now. He is threatening a criminal suit if I don't pay up. Are there any legal grounds for this?
