Trailer Bill of Sale: Free Template & State Rules (2026)

A trailer changes hands more easily than a car, but the paperwork trips up more people. Some trailers have a title, some do not, and the rules flip depending on weight and the state you live in. This guide explains exactly what a trailer bill of sale needs to contain, when a title is involved, which states notarize the document, how to register a trailer after you buy it, and the scams to watch for — with a free template at the end.

What a Trailer Bill of Sale Is

A trailer bill of sale is a written record of a private trailer sale. It identifies the buyer and seller, describes the trailer, states the price, and is signed by both parties. It does two jobs at once: it is the receipt that proves the sale happened, and it is the document most state DMVs accept as evidence of ownership when a trailer has no title.

That second job is why trailer paperwork matters more than people expect. A surprising number of trailers — especially small utility and homemade ones — never received a title. When there is no title, the bill of sale becomes the primary chain-of-ownership document. If it is vague or missing, the buyer can be stuck unable to register the trailer and the seller can be chased for unpaid tolls, tickets, or abandonment fees long after the trailer is gone.

Utility vs Travel/RV Trailer — the Differences That Matter

"Trailer" covers a wide range of equipment, and the type changes how the sale is documented and registered.

Utility and cargo trailers

Open utility trailers, enclosed cargo trailers, flatbeds, dump trailers, car haulers, and boat trailers are valued mainly by their hauling capacity. The defining numbers are the gross vehicle weight rating (GVWR), axle count, and bed length. Lighter utility trailers are the ones most likely to fall below a state titling threshold and be registered with a bill of sale alone.

Travel trailers and RVs

Travel trailers, fifth wheels, and toy haulers are living spaces on wheels. They are almost always titled and registered like a vehicle regardless of weight, and they carry higher values, so the bill of sale should itemize anything included (awnings, generators, solar, appliances) and note their condition. If you are buying a motorhome rather than a towable, a dedicated RV form is a better fit than a generic trailer form.

The practical takeaway: a $600 utility trailer and a $30,000 travel trailer use the same basic bill-of-sale structure, but the travel trailer almost certainly involves a title transfer and a lien check, while the utility trailer may not.

What to Include in a Trailer Bill of Sale

A complete trailer bill of sale should capture the following. The more specific you are, the smoother the DMV trip and the stronger your protection if the sale is ever questioned.

Trailer details

• VIN or serial number: The 17-character VIN for factory trailers, stamped on the frame and printed on the certification label. Record the manufacturer serial number if there is no VIN, and note "no VIN" explicitly if the trailer has none.
• Year, make, and model: e.g., "2021 Big Tex 70PI". For homemade trailers, write "homemade" or "shop-built" and the year completed.
• Trailer type: Utility, enclosed cargo, flatbed, dump, car hauler, boat, horse, or travel/RV.
• GVWR (gross vehicle weight rating): The maximum loaded weight from the certification label. This number often decides whether the trailer needs a title and which registration class applies.
• Empty/curb weight: Helpful for registration fees and for towing-capacity matching.
• Axle count: Single, tandem (two), or triple axle — affects both value and registration class.
• Length and deck dimensions: Measured in feet.
• Color and notable features: Ramps, side rails, spare tire, electric brakes, etc.

Sale information

• Full legal names and addresses of buyer and seller
• Sale price (or "gift" with $0 if no money changes hands — note that some states still assess tax on the trailer's market value)
• Date of sale
• Payment method
• As-is clause: Almost every private trailer sale is "as-is, no warranty." Spelling this out protects the seller from later claims about rust, bad bearings, or worn tires — though it never excuses hiding a known defect.
• Signatures of both parties (and a witness or notary line if your state requires one)

Make two copies, signed in ink — one for each party. The buyer needs the original for the DMV; the seller keeps a copy for tax records and as proof they no longer own the trailer.

Do Trailers Have Titles? A State-by-State Overview

This is the question that confuses most trailer buyers, and the honest answer is: it depends on your state and the trailer's weight. There is no single national rule. Broadly, states fall into three groups.

States that title most trailers

Many states issue a title for trailers much like they do for cars, regardless of size. In these states you transfer ownership by signing over the existing title, and the bill of sale is a supporting document for tax and proof of price rather than the main ownership record.

States that title only above a weight threshold

A large group of states title trailers only above a GVWR or empty-weight cutoff — commonly somewhere between 2,000 and 4,000 lbs, though the exact number varies. Below the threshold, the trailer is registered (you get a plate) but never titled, and the bill of sale is the ownership document. Above it, the trailer is titled like a vehicle. This is why two identical-looking utility trailers can be handled completely differently one state line apart.

States that do not title small trailers at all

Some states never title light utility trailers; they only register them. A few do not even require annual registration for the smallest non-commercial trailers. In these states, hold onto your bill of sale and the manufacturer's certificate of origin carefully — they are the only proof of ownership you will ever have.

Because the rules turn on both state and weight, never assume. Look up your state DMV's trailer page (search "[your state] DMV trailer title weight") before the sale so you know whether you are dealing with a title transfer or a bill-of-sale registration. Our bill of sale requirements by state guide breaks down the document rules for all 50 states, and our car bill of sale guide covers the title-transfer mechanics that apply to titled trailers too.

States That Require Notarization for a Trailer Sale

Most states do not require a trailer bill of sale to be notarized. Notarization tends to come up in two situations:

• States that notarize vehicle ownership documents generally. A small number of states require notarized signatures on title assignments or bills of sale for vehicles, and trailers can fall under those rules.
• Homemade or no-title trailers. When a trailer has no title and no VIN, some DMVs ask for a notarized bill of sale as part of the inspection-and-assignment process, because the notary's seal adds a layer of verification to an otherwise unverifiable ownership claim.

Even where it is optional, notarizing a higher-value trailer sale (a travel trailer, a large enclosed hauler) is cheap insurance. It costs a few dollars at a bank or shipping store and makes the document much harder to dispute. For the full picture, see our notarized bill of sale guide. Confirm your specific requirement with your state DMV, since the few states that mandate it apply the rule narrowly.

How to Register a Trailer After You Buy It

Once the sale is done, the buyer registers the trailer with the state. Deadlines vary — many states give you 10 to 30 days from the sale date before late fees apply — so do not let the paperwork sit. The general process looks like this.

1. Gather your documents. Bring the signed bill of sale, the title (if the trailer is titled) assigned over to you, the manufacturer's certificate of origin for a brand-new trailer, and your photo ID.
2. Get a weight slip if required. Many states register trailers by weight class. If the GVWR or empty weight is not documented, you may need a certified scale ticket.
3. Pass an inspection if there is no VIN. Homemade and VIN-less trailers usually need a physical inspection. The inspector verifies the trailer matches your paperwork and assigns a state VIN if one is missing.
4. Pay sales/use tax and fees. The DMV calculates sales or use tax from the price on your bill of sale (or the trailer's assessed value), plus registration and plate fees.
5. Receive your plate and registration — and a title, if your state titles trailers in that weight class.

If you are unsure exactly what your DMV wants on the document itself, our how to write a bill of sale guide walks through each field with examples.

Common Trailer-Sale Scams (and How to Avoid Them)

Trailers are a favorite target for fraud because they are easy to move, easy to re-sell, and frequently sold with thin paperwork. Watch for these.

• Curbstoning. An unlicensed dealer poses as a private seller to flip trailers (often with hidden problems or unclear ownership) while dodging dealer regulations and warranties. A "private" seller who has several trailers, won't put their name on the title, or wants the bill of sale left blank is a red flag.
• Washed-out or altered serial numbers. If the VIN plate is missing, ground off, re-riveted, or does not match the paperwork, stop. Altering a VIN is a crime and a strong sign the trailer is stolen. Photograph the VIN plate and confirm it matches the title or bill of sale exactly.
• Undisclosed liens. A titled trailer can carry a loan. If the seller still owes money, the lender — not you — legally holds the title, and the trailer can be repossessed after you pay. Run a lien check (your state DMV or a VIN lookup service) before paying for any titled trailer.
• "Lost title, I'll mail it later." Promises to send the title after payment often never materialize. For a titled trailer, complete the title assignment at the time of sale, not afterward.
• Stolen-trailer flips. Cheap, no-title, cash-only, and a seller in a hurry is the classic stolen-trailer profile. Verify ownership, meet in a safe public place, and walk away if anything feels off.

Buying a Trailer With a Boat? Read This Too

Boat trailers are often sold as part of a boat package, and the boat, the motor, and the trailer can each have their own paperwork. If a trailer is changing hands alongside a watercraft, itemize the trailer separately on the bill of sale and confirm whether your state titles the trailer on its own. Our boat bill of sale guide covers how the trailer fits into a combined boat sale, including hull and motor documentation.

Frequently Asked Questions

The Bottom Line

A trailer bill of sale is short, but it carries weight — literally and legally. Record the VIN or serial number, the GVWR and axle count, the price, and a clear as-is clause; check whether your state titles the trailer at its weight; verify there is no lien on anything titled; and keep a signed copy for your records. Do that, and registering the trailer is a formality instead of a headache.
