A trailer is being transferred separate from the towing vehicle. Trailers often have different titling rules than motor vehicles, including different weight thresholds that trigger title requirements.
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).

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.
