In Michigan what is the law on deposits. Can you request 1/3 x 3 or 50% up front? Is there any law for this?
In addition to the previous responses to your question, I will note that if you are receiving a deposit on a private construction project in Michigan, those funds are considered trust funds under the Michigan Builder's Trust Fund Act (MBTFA). You must use those funds to first pay your subs and suppliers on that particular job. You should not use the money to pay old bills on another project. You're asking for serious trouble if divert funds from the new job to use for other projects and come up short at the end of the job. The MBTFA is criminal statute which has been construed by the courts to apply in civil lawsuits and against the owners of construction firms personally.
