What to know about trailer sold separately sales in Illinois
Many states require trailers to be titled and registered separately from the towing vehicle once they exceed a weight threshold (commonly 1,000–3,000 lbs GVWR). If your trailer has a title, complete the title transfer. If it does not (because it is below the threshold), a bill of sale is the primary ownership document.
What to include in your bill of sale
- Full legal names and addresses for both buyer and seller.
- Personal Watercraft make, model, year, VIN, and current mileage.
- Agreed sale price, payment method, and transaction date.
- Any trailer sold separately-specific disclosures required in Illinois.
Seller guidance
Many states require trailers to be titled and registered separately from the towing vehicle once they exceed a weight threshold (commonly 1,000–3,000 lbs GVWR). If your trailer has a title, complete the title transfer. If it does not (because it is below the threshold), a bill of sale is the primary ownership document.
Buyer guidance
Confirm whether the trailer is titled in your state and whether the seller has the title. If moving the trailer across state lines, check the destination state's titling threshold — you may need to obtain a title even if the selling state did not require one. Verify the VIN or HIN plate on the trailer matches the title or documentation.
Legal considerations
Trailer titling requirements are set by state law. For example, California requires titling for trailers over 1,500 lbs unladen weight. Texas requires titling for trailers over 4,000 lbs GVWR. Some states (e.g., North Dakota) title all trailers regardless of weight. Boat trailers are often subject to a combined boat/trailer registration. Federal VIN requirements under 49 CFR Part 565 apply to trailers with a GVWR exceeding 10,000 lbs.
