Michigan Bill of Sale
Michigan keeps it simple for cars — title assignment, no notary, same-day instant titles — and reserves its bill of sale form, TR-207, for the trailers, boats, and snowmobiles that carry no title. Both lanes explained, with the 18-month rule every seller should know.
Two lanes: titled cars, and everything else.

Michigan specifics, answered.
What is Michigan's TR-207 actually for?
The non-titled fleet: trailers, watercraft, snowmobiles, and other property that transfers without a Michigan title. For a titled car the bill of sale is optional — the title assignment itself records the price and is the only proof of ownership the SOS accepts — but TR-207 or your own bill of sale remains the receipt both parties keep.
What's Michigan's 18-month photocopy rule?
The SOS's own advice to sellers who can't accompany the buyer to the branch: photocopy the completed title, front and back, and keep it at least 18 months. If the buyer never transfers the title and their parking tickets come looking for you, the photocopy is your proof of when the vehicle left your hands.
How fast can the buyer get a Michigan title?
Same day — Michigan's instant title service produces the new title at any SOS office for an extra $5 over the standard $15 mailed title. The catch: every owner going on the title must appear in person, no agents. The transfer itself is due within 15 days of purchase.
Does Michigan tax the price I actually paid?
Only if it's believable. The 6% use tax is charged on the greater of your purchase price or the vehicle's book retail value, and Treasury cross-references reported prices against the NADA database. An honest below-book price is defensible; a fictional one gets recalculated. No notarization is required anywhere in the process.
