Form TR-121 at a glance
What it is: The TR-121 Vehicle Uniform Surety Bond is to title or register without a properly assigned ownership document.
Who signs: The person applying for the title or registration must sign the surety bond. If a business or organization is applying for the title or registration, a representative of the business or organization must sign the surety bond. Applicants are named as the “Principal” and must include their complete residence or business address. A representative of the insurance company or bonding agency must sign the surety bond. A duly authorized agent of the surety company must issue the bond. If the agent is a licensed nonresident agent, a licensed resident agent must countersign the bond.
Before you can title or register a titled motor vehicle, titled trailer, trailer coach, moped, watercraft, ORV, or snowmobile without a properly assigned ownership document, you must file a Vehicle Uniform Surety Bond (TR-121) with the Michigan Department of State along with your title or registration application.
What to bring and attach to Form TR-121
Proof of the bond company's authorization to issue surety bonds must accompany the surety bond. The Michigan Department of Licensing and Regulatory Affairs must license the surety company.
In addition to the TR-121 Vehicle Uniform Surety Bond, all applicants must complete a TR-205 Self-Certification of Vehicle Ownership form. Incomplete forms will not be accepted. Forms with insufficient information will not be accepted.

Any interested party may bring an action in the party's own name to recover on this bond any damages sustained by the party for any breach of the conditions for which the bond is deposited, and may recover costs and reasonable attorney fees.
