If you’re a proud trailer owner in Michigan, registering your trailer is a crucial step to ensure legal and safe operation on the state’s roads. The process, while straightforward, has specific requirements and steps that need to be followed. Here’s a comprehensive guide to help you through it.
Determine if Your Trailer Needs to Be Registered
In Michigan, trailers and trailer coaches (such as pop – up campers, fifth wheels, and travel trailers) generally must be registered with a permanent trailer plate. Trailer coaches and pickup campers must be titled. Additionally, trailers that weigh 2,500 pounds or more must be titled. However, there are some exceptions. For example, certain trailers used for agricultural purposes may qualify for agricultural registration, which comes with reduced fees and different renewal requirements. Trailers used by governmental agencies or non – profits may also be eligible for exemptions. Non – profits using trailers for charitable activities can apply for exempt status, but they need to provide supporting documentation to prove their eligibility.
Gather the Necessary Documents

- Proof of Ownership: This is a crucial document. If you purchased the trailer from a dealership, they will typically provide you with a bill of sale. If it’s a private sale, ensure you have a detailed bill of sale from the previous owner. The bill of sale should include important details such as the make, model, year, and vehicle identification number (VIN) of the trailer. Other acceptable forms of proof of ownership could be the manufacturer’s certificate of origin (MCO) if it’s a new trailer, or the title if the trailer was previously titled.
- Vehicle Identification Number (VIN): The VIN is a unique 17 – digit code assigned to your trailer. It’s usually located on a plate attached to the trailer’s frame, often near the tongue or on the side of the trailer. Make sure the VIN on your documents matches the physical VIN on the trailer. If you can’t find the VIN, it’s important to contact the previous owner or the manufacturer for assistance.
- Proof of Insurance: You’ll need to show proof that your trailer is insured. Contact your insurance provider and obtain a copy of the insurance policy that covers the trailer. Michigan law requires trailers to be insured, and having this documentation ready will speed up the registration process.
Calculate and Prepare the Registration Fees
The registration fees for trailers in Michigan are determined by the trailer’s empty weight. As of 2023, trailers under 2,500 pounds incur a $75 fee, while those over 2,500 pounds are subject to a $200 fee. These fees support the state’s registration system and infrastructure. It’s important to note that if you’re registering a trailer that has been previously registered in another state, you may also be required to pay a transfer fee. Make sure you have the exact amount of money ready, as some Secretary of State branch offices may only accept certain forms of payment, such as cash, check, or credit card.
Choose Your Registration Method
- Online Registration: Michigan has made trailer registration more convenient by offering an online option. To register your trailer online, you’ll first need to create an account on the Michigan Secretary of State’s website. During the account creation process, you’ll be asked to provide personal identification information, such as your driver’s license number, and details about the trailer, including its VIN, weight, and type. Once your account is set up, log in to the registration portal and enter all the required information accurately. The system will verify the information against existing records to ensure accuracy and prevent fraud. After entering all the details and paying the registration fee online, you’ll be able to print out a temporary registration receipt immediately. Your permanent registration plate and decal will be mailed to you.
- In – Person at a Secretary of State Branch Office: If you prefer a more hands – on approach, you can visit a Secretary of State branch office. Find the nearest branch location, which can usually be located through the Michigan Secretary of State’s official website. Bring all the necessary documents, including proof of ownership, VIN, and proof of insurance, along with the appropriate registration fee. At the office, you’ll need to fill out a trailer registration application form. A clerk will review your documents, verify the information, and process your registration. You’ll receive your registration plate and decal on the spot.
- By Mail: You can also register your trailer by mail. Download the trailer registration application form from the Michigan Secretary of State’s website. Fill out the form completely and accurately, attaching all the required documents, such as the proof of ownership, a copy of your driver’s license, and proof of insurance. Include a check or money order for the correct registration fee, made payable to the Michigan Secretary of State. Mail the entire package to the address specified on the application form. Processing times for mail – in registrations can take longer, usually a few weeks, so it’s important to plan ahead if you choose this method.

Temporary Registration Permits
If you need to move your trailer before completing the full registration process, Michigan offers temporary registration permits. These permits allow you to legally operate your trailer on public roads for up to 30 days. To obtain a temporary permit, you’ll need to provide proof of insurance and pay a nominal fee. This option is especially useful for those who have recently purchased a trailer and need some time to gather all the necessary documentation for permanent registration.
Renewing Your Trailer Registration
Trailer registrations in Michigan typically do not need to be renewed in the same way as vehicle registrations. The permanent trailer plate is not renewed. However, if your trailer is titled, and there are any changes to the information on the title, such as a change of address or a transfer of ownership, you’ll need to update the title accordingly.
In conclusion, registering your trailer in Michigan is an important task that ensures you can use your trailer legally and safely. By following these steps, gathering the right documents, and choosing the most convenient registration method for you, you’ll have your trailer registered and ready to hit the road in no time.
