A trailer bill of sale in Ohio is the written record of a private trailer sale, and what it needs to do depends on the trailer’s weight. For a utility trailer under 4,000 pounds, the bill of sale is your primary proof of ownership and the document you’ll take to a deputy registrar for plates. For anything heavier, the bill of sale supports the transaction but doesn’t replace the certificate of title that Ohio requires the seller to sign over to you.
What to Put in the Document
Ohio doesn’t mandate a specific form. It does expect the paper to hold up under review at the BMV or Clerk of Courts, which means it has to contain enough information to identify the parties, the trailer, and the deal.
- Full legal names and current residential addresses for both buyer and seller.
- A trailer description specific enough that no one could confuse it with another: manufacturer, model year, color, and the Vehicle Identification Number.
- The exact purchase price in dollars. Ohio calculates sales tax from this figure at registration, and an artificially low number can trigger scrutiny.
- The calendar date of the sale. For titled trailers, this date matters because Ohio runs a 30-day clock on the transfer.
- Signatures from both parties.
If the trailer is homemade or has no VIN, say so plainly in the description. Ohio has a separate form for that situation (covered below).
As-Is Language
Most private trailer sales in Ohio are as-is, meaning the buyer takes the trailer in its current condition without guarantees. Put that in writing. A single sentence handles it: “The trailer is sold in as-is condition with no warranties expressed or implied.” Without that language, a buyer can later argue that implied warranties applied to the sale, particularly around the trailer’s fitness for its intended use.
Warranty of Title Still Applies
As-is doesn’t cover ownership. Under the Uniform Commercial Code, which Ohio has adopted, every sale carries a warranty that the seller actually owns the goods and that they’re free of security interests the buyer didn’t know about.1Legal Information Institute (LII). UCC 2-312 – Warranty of Title and Against Infringement Disclaiming that warranty takes very specific language or circumstances. If you later discover the trailer had an outstanding lien, you may have a claim against the seller regardless of the as-is clause.
When You Also Need a Title
Ohio’s certificate of title law only covers trailers and semitrailers whose unladen weight exceeds 4,000 pounds.2Ohio Legislative Service Commission. Ohio Code 4505.01 – Certificate of Motor Vehicle Title Law Definitions Below that line, no title exists and the bill of sale carries the ownership record on its own. You’ll take it to any deputy registrar license agency for registration and plates.3Ohio BMV. New Registration
Above 4,000 pounds, titling is mandatory. Travel trailers, large enclosed trailers, campers, and heavier utility units all fall under it. For these sales you need the existing certificate of title properly assigned by the seller, and the bill of sale supports rather than substitutes for that assignment. Without a valid title assignment, Ohio courts won’t recognize your ownership interest no matter how well-drafted the bill of sale is.4Ohio Legislative Service Commission. Ohio Code 4505 – Certificate of Motor Vehicle Title Law
This is where sales go wrong. If you’re buying a heavy trailer and the seller can’t produce a title, don’t accept a bill of sale as a workaround. There isn’t one.
Notarization
Ohio requires the application for a certificate of title to be sworn before a notary public or another officer authorized to administer oaths.5Ohio Legislative Service Commission. Ohio Code 4505.06 – Application for Certificate of Title For a titled trailer, that means the seller’s assignment on the back of the title and the buyer’s application both pass through a notary before you file at the Clerk of Courts. Erasures or alterations on the assignment void the document entirely.6Ohio Legislative Service Commission. Ohio Code 4505.07 – Forms for Certificates and Applications The notary verifies the seller’s identity with government-issued ID and confirms the signature is genuine.
Ohio caps in-person notary fees at $5 per act, and banks, shipping stores, and some auto dealerships offer the service. Handle it while the seller is still with you. Chasing a seller down for a missed notarization can delay your registration by weeks.
For a trailer under 4,000 pounds, notarization of the bill of sale isn’t legally required. Having both signatures notarized anyway makes the document harder to dispute if ownership questions come up later.
Where to File, and What It Costs
Where you go depends on whether a title is involved.
- Titled trailers over 4,000 pounds go to the County Clerk of Courts Title Office. You submit the assigned title, the notarized title application, and the bill of sale. The clerk issues a new certificate of title in the buyer’s name. The fee for the new title typically runs about $18.
- Non-titled trailers under 4,000 pounds go to any deputy registrar license agency, with the bill of sale and proof of identity. The registrar processes registration directly.3Ohio BMV. New Registration
Sales tax is calculated from the price on your bill of sale. The state base rate is 5.75%, and every county adds a permissive tax on top, bringing totals to roughly 6.50% in the lowest-tax counties and above 7.55% in five counties.7Ohio Department of Taxation. Sales and Use Tax Rate Map The rate applied is based on the buyer’s county of residence. On a $5,000 trailer that works out to roughly $325 to $400.
Registration fees for non-commercial trailers scale with unladen weight. As of January 2026, annual fees range from $21 for the lightest trailers (under 500 pounds) up to $145 for trailers near 10,000 pounds, with a $16 administration and enforcement fee built into each tier.8Ohio BMV. Non-Commercial Trailer Registration Fees Effective 01-01-2026 A mid-size utility trailer around 2,000 pounds runs about $35 a year. Ohio also offers a permanent trailer registration: pay eight years of fees upfront, receive a non-transferable permanent plate that stays with the trailer while you own it.9Ohio BMV.

The 30-Day Deadline for Titled Trailers
You have 30 days from the notarization date on the title assignment to file for a new title. Missing the window adds a $5 late filing fee, and operating an unregistered trailer on Ohio roads exposes you to citations. For non-titled trailers there’s no formal title deadline, but you still can’t legally tow the trailer on public roads without registration, so a deputy registrar visit shortly after the sale is the practical answer.
Check for Liens Before You Pay
On a titled trailer, the certificate itself shows any lienholder claim. Read the lien section before money changes hands. If a lien is listed, the seller has to satisfy the debt and get a release before the Clerk of Courts will process a clean transfer. Buying around an unsatisfied lien risks losing both the trailer and your money.
Non-titled trailers have no state record to check, which puts more weight on the paper trail. Ask the seller for their own bill of sale or registration receipt to establish a chain of ownership.
Homemade Trailers Without a VIN
A trailer you or the seller built won’t have a manufacturer-assigned VIN, and Ohio needs an identifier before it can register the trailer. The BMV form for this situation is the Affidavit of Trailer Type (BMV 3787). Bring it to the deputy registrar with detailed documentation: receipts for the axle, frame, and major components, and photographs of the completed trailer. The BMV verifies the trailer’s origin and assigns a serial number that goes into the state’s tracking system. Until that number exists, the trailer can’t be registered or legally towed.
