If you purchase a boat in Florida, chances are it will come with a trailer. Do not forget to register your trailer when you register the boat, or you will be fined for towing an unregistered vehicle. The process of registering the trailer will depend on several factors, including the weight of the trailer and whether the trailer was previously registered by someone else. There are also fees involved, which can vary by county, so check with your local Department of Motor Vehicles office for boat trailer registration details.
Go to the DMV
Take the trailer title to your local Department of Motor Vehicles office (DMV). If you do not have a title, go to the nearest tax collector's office and apply for one. You will need the trailer's Vehicle Identification Number if the trailer weighs over 2,000 pounds. If it weighs less than 2,000 pounds, all you need is a bill of sale stating the sale price and weight of the trailer. Present your documents at the DMV, along with any applicable fees. Fees vary by county, and depend on whether you are applying for a new registration or for a transfer. Affix the license plate you receive from the DMV onto the trailer and remember to carry the trailer registration document with you in the car.
