What happens if I tryed to purchase my plates for my car falselym in Michigan?

I purchased a van last Saturday, and I went on line to purchase insurance for the van, when on Monday I went to the secretary of states office in michigan, they kept my proof of insurance and said it was no good. the today a state of michigan police officer from Southwestern Commercial Auto Recovery (SCAR) came and wanted to speak to my husband, but just after that on Monday we went accross the street and paid for proof of insurance they gave us a temp plate because I am handicapped. What will happen?
