How to write a bill of sale for a trailer
The VIN or serial number is the important field
Trailers manufactured after 1981 have a 17-character VIN stamped on the tongue or frame; older or homemade trailers have a shorter serial number, or none. If the trailer has no VIN, most states require an inspection to assign one before it can be titled. Record whatever number is stamped on the frame — this is what the DMV matches to the title.
Describe the trailer
Year, make, model or type (utility, enclosed, dump, gooseneck, boat), overall dimensions (e.g., 6 x 12 ft), gross vehicle weight rating (GVWR), and number of axles. Axle count and GVWR often determine whether the trailer needs to be titled and registered at all — many states exempt small utility trailers under 3,000 lb GVWR.
Titling rules vary
Some states title every trailer; some only title trailers above a weight threshold; a handful (like Maine) title none. Whether or not your state issues a title, both parties should still keep a signed bill of sale — it's the primary ownership record for lighter trailers and it establishes the tax basis and transfer date.
As-is clause and included accessories
Include the standard as-is line so post-sale complaints about the ramp door, coupler, or wiring don't come back to the seller. If the sale includes accessories — spare tire, ramps, tool box, hitch, tie-downs — list them in the item description. "Sold with 2 ramps, spare tire, and 2-5/16 ball hitch" prevents later disputes.
Signatures and next steps
Both parties sign and date. Two copies. If your state titles the trailer, take the signed title and bill of sale to the DMV; if it doesn't, register the trailer in the buyer's name (if required) and keep the bill of sale with your other vehicle records. Solda's template asks for all of these fields in order.
