Michigan Law requires disclosure of the actual odometer reading at the time of transfer or assignment of the vehicle's title.  Further, the seller must indicate if that reading is actual mileage, not actual mileage, or exceeds the maximum limit of the odometer (usually over 99,999 miles).  This disclosure is not required if the vehicle has a gross vehicle weight rating of more than 16,000 pounds, is not self-propelled, or is 10 years old or older.  (MCL 257.233a)

Federal Law also requires sellers to state the odometer mileage when transferring ownership.  Failure to complete a mileage disclosure or providing false information may make the seller liable for damages and fines and/or imprisonment according to the Motor Vehicle Information and Cost Savings Act of 1972, Public Law 92-513.
