Do I need a bill of sale to sell a trailer?

Yes. A trailer bill of sale documents the private transfer between buyer and seller, captures the sale price for tax purposes, and gives the buyer evidence of ownership. Most states require a signed bill of sale to register or title a trailer purchased from a private seller.

Do all trailers need to be titled?

No. Titling rules depend on the state and the trailer's gross vehicle weight rating (GVWR). Many states only title trailers above a weight threshold, often around 1,500–3,000 lbs, while smaller utility trailers are registered without a title. The bill of sale is the primary ownership record for any trailer that does not receive a title.

Where do I find a trailer's VIN or serial number?

Most modern trailers have a 17-character VIN stamped on the frame near the tongue or on the manufacturer's certification label, usually attached to the curbside (right) frame rail. Older or homemade trailers may have a shorter serial number, no number, or a state-assigned VIN issued at first registration.

What if my trailer was homemade and has no VIN?

For homemade or unmarked trailers, the buyer typically needs to apply for a state-assigned VIN at the DMV, which usually requires a bill of sale, photographs, weight slip, and an inspection. Note "homemade — no VIN" or the state-assigned VIN on the bill of sale itself so there is no ambiguity at registration.

What information should a trailer bill of sale include?

Include the VIN or serial number, year, make, model, type (utility, cargo, travel, boat, horse), color, GVWR, sale price, sale date, full legal names and addresses for buyer and seller, and signatures. If your state requires notary acknowledgement, include that as well.

Is sales tax owed on a private trailer sale?

Most states levy use tax on private trailer sales just like motor vehicle sales. The buyer typically pays the tax at registration based on the price recorded on the bill of sale, so the figure should be accurate and match what was actually paid.

Why a trailer sale needs its own bill of sale

Trailers are unusual in private-sale paperwork because their treatment changes dramatically with weight, type, and state. A 1,200 lb utility trailer might not need a title at all, while a 14,000 lb gooseneck moves through the same DMV channels as a commercial truck. A clean, well-written bill of sale is the one document that works across all of those scenarios — it locks in the VIN or serial, the sale price, the sale date, and both parties' signatures regardless of what the state titling office does next.

Buyers rely on the bill of sale to register the trailer, claim insurance, and prove ownership at weigh stations or roadside inspections. Sellers rely on it to release liability for any incident that happens after the date of sale. For homemade or inherited trailers without a clear paper trail, the bill of sale is often the only evidence the DMV will accept when issuing a state-assigned VIN.

What to include on a trailer bill of sale

VIN or serial number — most trailers have a 17-character VIN on the frame or certification label; record exactly what is stamped or printed. Note "homemade — no VIN" if no number exists.
Year, make, model, and type — utility, cargo, travel, boat, horse, dump, gooseneck, etc.
GVWR — the gross vehicle weight rating from the manufacturer plate; this drives whether your state requires a title.
Sale price and sale date — used for use-tax calculation at registration.
Full legal names and addresses for buyer and seller, plus contact info.
Signatures, date, and notary block if your state requires acknowledgement on titled trailers.
"As-is" language — most private trailer sales are as-is with no warranty; stating that protects the seller from later repair claims.

State-by-state notes for trailer sellers

Trailer titling thresholds vary by state, and they often differ from car titling rules. The notes below highlight a few common patterns; always confirm the exact threshold and registration office with your state's DMV before signing.

Texas, Florida, California: trailers above a state-set weight threshold are titled and registered through the DMV; smaller utility trailers may register without a title. The bill of sale is required either way.
New York, Pennsylvania, Ohio, Illinois: most trailers above the minimum weight threshold are titled like motor vehicles; a signed bill of sale is required for transfer.
Wyoming, Montana, South Dakota: trailer titling rules vary widely; some smaller trailers register on a permanent or multi-year plate without title transfer at private sale.
Homemade or no-VIN trailers: nearly all states require an inspection and a state-assigned VIN; the bill of sale is the foundational document that starts that process.
Other states: titling and registration thresholds vary by GVWR — see your state's DMV trailer page for the exact rule.
