You found a buyer for your 2019 F-150 in a Tulsa parking lot, agreed on $18,500, and shook hands. Then comes the paperwork question: does the title need a notary? Does the bill of sale? What if the title is electronic — which most newer Oklahoma titles are? The answer tripped up a seller we met last month, who showed up at Service Oklahoma with a signed title and no notarization, and got sent home. Here's the full picture of when Oklahoma vehicle sales need a notary, what gets signed where, and how to close the deal without a second trip.
The Short Version: What Must Be Notarized
Oklahoma law is specific about vehicle transfers. Under 47 O.S. § 1107, when a titled vehicle is sold, the seller must endorse on the back of the certificate a complete assignment with warranty of title and a statement of all liens, sworn to before a notary public — then hand the title to the buyer at delivery. That's the rule for paper titles, and it's not optional.
For electronic titles, the mechanics change but the notarization stays. The seller can't physically sign the back of a title they don't hold, so Oklahoma uses Form 718, Bill of Sale of an Electronic Title. The seller affirms and attests that they hold an electronic title and assigns ownership to the buyer, and the form must be subscribed and sworn to before a notary. In other words: yes, that bill of sale gets notarized.
The buyer then has 30 days from delivery to present the assigned title (or Form 718), proof of insurance, purchase-price documentation, and the $11 transfer fee to Service Oklahoma or a licensed operator, along with any motor vehicle excise tax. Miss the window and you're looking at late fees and, in the worst cases, the vehicle sitting unregistered while the old owner's name stays on the record.
Paper Titles vs. Electronic Titles: Two Different Signing Ceremonies
Oklahoma issues most new titles electronically these days, but plenty of older vehicles still have paper certificates. Here's how each one plays out at the notary's table.
Paper Title: Assignment on the Back
The seller fills in the assignment block on the back of the title — buyer's name, sale price, odometer reading, lien statement — and signs it in the notary's presence. The notary administers the oath or takes the acknowledgment, verifies the seller's identity with a current government-issued ID, stamps and signs the certificate, and records the act in the notary journal. The buyer signs nothing on the title itself in most cases; the buyer's name goes in the assignment block as the transferee.
One warning we give every seller: do not sign the title before the notary arrives. The assignment must be sworn to before the notary. A pre-signed title leaves the notary unable to administer the oath at the moment of signing, and many notaries will refuse. If you already signed, the clean fix is signing again in front of the notary (if there's room) or checking with Service Oklahoma before the buyer walks away with a title Service Oklahoma may reject.
Electronic Title: Form 718 Bill of Sale
If the title on record is electronic, Service Oklahoma's instructions are explicit: use Form 718. Both parties fill it out completely — the form literally warns "void if altered" and that incomplete submissions may not be accepted. The seller signs under oath before a notary, attesting that they hold the electronic title and assigning ownership to the buyer. The buyer also signs the form as transferee. Additional paperwork often rides along: Form 729 odometer disclosure for 2011+ vehicles, Form 722-1 declaration of purchase price, or a purchase agreement if a dealer is involved.
A mobile notary is the practical answer here because Form 718 closings happen wherever the sale happens — a driveway in Broken Arrow, a parking lot in Norman, a farm gate in Woodward. The notary brings the journal, witnesses the oath, and both parties walk away with a complete, notarized package instead of a maybe-valid title.
The Bill of Sale: When It's Needed and When It's Optional
There's a lot of confusion about the humble bill of sale, so let's separate what's required from what's smart.
Required: For electronic titles, Form 718 is the transfer document — it's a bill of sale by name and by function, and it must be notarized. Dealers also must execute bills of sale on Service Oklahoma forms for all new vehicles sold. For paper-title private sales, a bill of sale is not strictly required, but Service Oklahoma does require purchase-price documentation: a bill of sale, purchase contract, Form 722-1, or sales agreement.
Smart even when optional: A notarized bill of sale is the best possible proof of the transaction if anything goes sideways later — the buyer claims they paid more, the seller claims they were paid less, a lienholder disputes the sale, or the IRS asks about the sale price. The notary's journal entry records the date, the signer, the document type, and the ID presented. That's evidence that survives.
What a bill of sale does not do is transfer title. Ownership transfers through the assigned certificate of title (or Form 718 for electronic titles). A bill of sale alone — even a notarized one — does not make the buyer the legal owner. It proves the deal; the title proves the ownership.
Odometer Disclosure: Form 729 and the Mileage Rule
Under 47 O.S. § 1107.1, the seller must verify the mileage at transfer and disclose it in writing on the title or a separate document, certifying one of three things: the reading reflects actual mileage, the reading does not reflect actual mileage, or the mileage exceeds the mechanical limits of the odometer. For vehicles from 2011 or newer, Service Oklahoma requires a completed odometer disclosure statement — usually built into the title assignment, or on Form 729 when it isn't.
Both transferor and transferee sign and print their names on the disclosure. Federal law backs this up: a false odometer statement can mean fines and imprisonment. The notary's role here is limited — the notary handles the title assignment oath, not the odometer certification itself — but a notary can witness the whole package being signed so the seller doesn't juggle three separate signing events. One appointment, every signature witnessed, everything journaled.
Boats, Trailers, ATVs, and the Rest of the Garage
The same notarized-assignment logic applies beyond cars. Boats and outboard motors titled in Oklahoma transfer through the BM-26 application and the same assigned-and-notarized certificate rules under 47 O.S. § 1107. Trailers with titles follow suit. Off-road ATVs and utility vehicles sold by retail implement dealers move through dealer title reassignment, which is the dealer's job, not the buyer's.
The recurring theme: if there's a certificate of title, the assignment gets notarized. That's true whether the "vehicle" is a bass boat on Lake Texoma, a horse trailer in Stillwater, or a side-by-side in the Ouachitas. And when a boat or trailer has no title at all (some older units were never titled), a notarized bill of sale becomes your best evidence of ownership for registration — worth having even when no one demands it.
How to Prep for the Notary: A Seller's Checklist
A notary visit should take ten minutes, not an hour. Here's what makes it smooth:
- Leave the signature lines blank. The title assignment and Form 718 must be signed in the notary's presence. No pre-signing, no "just add my signature later."
- Bring a current government-issued ID. Driver's license, passport, or state ID with photo and signature. The notary verifies identity under 49 O.S. § 113.
- Know the odometer reading and sale price. Those go on the title assignment and the disclosure. Don't guess — the notary isn't the one certifying mileage, but the seller is, under penalty of law.
- Have the VIN handy. Both parties should verify it matches the vehicle. A VIN typo on a title assignment can stall the transfer for days.
- Line up both parties. The notary needs the seller for the oath; the buyer should be present to sign Form 718 and the odometer disclosure. If the buyer can't be there, ask the notary how to handle it before the appointment.
- Know which title type you have. Paper title? Bring it. Electronic title? Download and print Form 718. Wasting a notary visit on the wrong form wastes everyone's time.
And if the sale is out of state — say a buyer from Texas is taking the truck home — check Service Oklahoma's rules for out-of-state dealer assignments. Oklahoma does not require notarization on assignments to or from out-of-state dealers located in non-notary states, but private out-of-state buyers should still get the notarized package to avoid a title headache in the buyer's home state.
What It Costs and Where the Notary Comes To You
The notarial act itself is capped at $5 per act under 49 O.S. § 5. A title assignment is one act; a Form 718 oath is another; add an acknowledgment and you're at three. Travel, after-hours, and courier fees are separate — which is exactly why a mobile notary makes sense for a vehicle sale. You're already meeting in a parking lot or driveway; the notary meeting you there is the natural fit.

Conclusion
Oklahoma vehicle sales come down to three documents and one rule: the title assignment must be sworn to before a notary under 47 O.S. § 1107, electronic-title sales need the notarized Form 718 bill of sale, and the odometer disclosure (Form 729 for 2011+ vehicles) rides along under 47 O.S. § 1107. Get those signed in front of a notary, hand the buyer the package with proof of insurance and the $11 fee, and the 30-day clock starts clean.
