The Michigan Tr 121 form, known as the Vehicle Uniform Surety Bond, plays a crucial role in the process of titling and registering vehicles, watercraft, and snowmobiles in Michigan. When an applicant seeks to obtain a title or registration for a unit without a clear record of ownership, this form must be filed with the Michigan Department of State. The bond amount is set at twice the value of the vehicle, watercraft, or snowmobile, ensuring adequate financial protection for all parties involved. It is important to note that certain exemptions apply; for instance, vehicles over ten years old valued at $2,500 or less may not require a bond. The applicant, referred to as the "Principal," must provide their full name and address, while a representative from an authorized surety company must also sign the bond. This bond serves to indemnify the Michigan Department of State and any interested parties against potential losses related to ownership disputes. The bond remains in effect for three years, unless a valid title or registration is surrendered. Understanding the requirements and implications of the Tr 121 form is essential for anyone navigating the complexities of vehicle registration in Michigan.
