Potentially. If you are a professional who contracts work for homes or businesses, there are facts and circumstances that the government considers when deciding whether they believe a disagreement is a civil contract dispute, or a criminal fraud or theft. The police or prosecutor will consider how much money was paid upfront; how much work was completed, if any; whether any tools or materials were purchased in advance; and the nature and character of the work provided. If the police contact you to discuss the job or the contract, they are likely doing so as part of a criminal investigation and in all cases, you should contact an attorney prior to speaking with them.
