Signing a Ohio title takes about ninety seconds once you know which boxes matter. Getting one of them wrong sends the buyer back to a county Clerk of Courts title office and the car back to your driveway. Here is the whole thing, taken from the Ohio Bureau of Motor Vehicles's own pages and the forms themselves.
Start hereHow to fill out an Ohio titleThe assignment of ownership on the back of the certificate, block by block - and the notary you have to sign it in front of.Open the walkthrough →Ohio prints a CHECK ONE column beside the mileage: Actual Mileage, EXCESS of the Mechanical Limits, not the actual Mileage, and Exempt from mileage disclosure. That last box has three examples printed next to it - APV, Repossession, Inheritance - and none of them is “the car is old”. Ticking Exempt on a 2017 crossover because it feels old enough is a false statement on a notarised document.
There is no Ohio age exemption. The age rule is federal, at 49 CFR 580.17, and it turns on the model year: built 2010 or earlier and the vehicle drops out of disclosure at ten model years; built 2011 or later and the wait is twenty, so a 2011 does not go exempt until 2031. What Ohio adds on top is a list of transaction types that need no mileage at all - a bequest, intestate succession, a survivorship or transfer-on-death passing, the creation of a security interest, or a gross vehicle weight rating above sixteen thousand pounds. That is a list of situations, not of birthdays.
2010 model year or older: Age-exempt under the federal rule. The Exempt box is available to you.
2011 model year or newer: Not age-exempt, and will not be for years. Write the reading in whole miles - the boxes are labelled “no tenths”.
An inherited car, a survivorship passing or a repossession: Exempt whatever the year, because Ohio exempts the transaction rather than the vehicle.
Over 16,000 lb GVWR: Exempt under the same subsection of R.C. 4505.06.

You, the seller: Complete the assignment of ownership on the reverse of the certificate - buyer's name and address, date of delivery, price and mileage - and then sign it in front of a notary. Do not sign it before you get there. Every owner named on the front has to sign, and the signature has to match the name printed on the face of the title.
The buyer: Signs the application half of the same document, also before a notary, and takes it to a county Clerk of Courts title office with photo identification, the sales tax and the title fee. In Ohio the buyer files - there is nothing for the seller to post afterwards.
A pen slip is not fixable here. The reverse of an Ohio title opens with a line that R.C. 4505.07 requires it to carry in bold: ERASURES AND ALTERATIONS VOID THIS TITLE ASSIGNMENT. BMV 3770 repeats it in a box of its own. There is no initialling a correction and no tidying it up with correction fluid - a spoiled assignment means the owner buys a replacement title before anything can be sold.
Which is also why the form says all blank spaces above must be completed before acknowledgement, and to insert NA or NONE where something does not apply. A notary is not supposed to take an acknowledgement on a document with gaps left to be filled in later.
The BMV puts it in one sentence: the seller must complete the assignment of ownership portion on the back of the title and have their signature(s) notarized. The statute puts the same requirement on the other half - an application for a certificate of title shall be made in a form prescribed by the registrar of motor vehicles and shall be sworn to before a notary public or other officer empowered to administer oaths. Two signatures, two acknowledgements, and the clerk of courts counter has notaries on staff so both can be done in the same visit.

The full box-by-box walkthrough is here, with a printable checklist.
An assignment signed in front of a notary, a mileage certification with four boxes and only one right answer, and a buyer who has thirty days to get to the clerk.
Ohio has no lien-release form to fill in - the lender releases on the face of the title or electronically - so the seller's job is proving it happened before a buyer asks.
Lost, never printed, or spoiled by a correction. All three end at the same window and mostly on the same form.
Signing through somebody else, or signing at seventeen: the two authorities an Ohio clerk of courts will accept in place of the owner at the counter.
Ohio moves a car out of an estate without probate in two different ways, and which one applies was decided while the owner was alive.
A total loss the insurer is taking, and a vehicle identification number that has stopped being readable.
The registration expires the moment you sell. These are the three things Ohio lets you do with the plates you take off.
R.C. 4503.12(A) is unusually blunt about it: upon the transfer of ownership of a motor vehicle, the registration of the motor vehicle expires, and the original owner immediately shall remove the license plates from the motor vehicle. Not at your convenience, not when the buyer sends them back. The registration dies with the sale; the plates are yours and go home in your boot.
There are three honest destinations for them. Move the registration and the plates onto the next vehicle you buy - the statute gives you the remainder of the registration period, the transfer has to be completed within thirty days, and during those thirty days the old plates may legally be displayed on the new car. Hand them in and cancel the registration on BMV 4311. Or, if the number is going to a spouse or a leasing company, release it on BMV 4729.
What you must not do is leave them on the car as a favour so the buyer can drive it home. The plate stays attached to your record, and R.C. 4503.12(D) makes a violation of that subsection a misdemeanor of the fourth degree. If the buyer needs to drive it away, the answer is a forty-five-day temporary tag from a deputy registrar, and the BMV's own note is that it must be obtained before the title is transferred into their name.
The transfer itself is the BMV's business, not the clerk of courts': $9.00 for a plate or registration transfer at a deputy registrar licence agency, with the statutory transfer fee of one dollar folded into it.
There is nothing to file. That sentence surprises people who have sold a car in California or Texas, so it is worth saying plainly: Ohio publishes no notice of sale and no release of liability, and the BMV's index of 121 forms contains no way for a private seller to report a sale. What ends your connection to the car is the plates coming off, which under R.C. 4503.12(A) expires the registration the moment ownership transfers.
Which puts the weight on the two things you actually control. Take the plates with you at handover, and get the assignment filled in and notarised correctly so that nothing sends the buyer back. The buyer then has thirty days: in all cases of transfer of a motor vehicle except the transfer of a manufactured home or mobile home, the application for certificate of title shall be filed within thirty days after the assignment or delivery of the motor vehicle. Miss it and the clerk collects an extra five dollars, which is printed on the face of BMV 3774 and in bold across the foot of BMV 3770.
Keep a photograph of the assignment, and deal with the plates.
With no notice of sale to file, your own copy is the whole of your evidence that the car went to a named person on a named day. Photograph both halves of the notarised assignment - the buyer's printed name and address, the date of delivery, the price, the mileage and the notary block - before the buyer walks off with it. If you also want the record itself, a Clerk of Courts Vehicle Title Record Request on BMV 1174 will show you when the title moved and into whose name. And where the plates are not going onto another car, cancelling the registration outright is the closest Ohio gets to telling the state you are finished with it.

Register at a county Clerk of Courts title office within 30 days of the purchase. Sales tax is the buyer's and it is paid to the clerk, not to you: five and three-fourths per cent to the state under R.C. 5739.02 plus whatever the buyer's own county adds, charged on the purchase price you wrote into the assignment. The title fee is $18 statewide, or $23 in a county whose officials approved the additional charge, and there is a further $5 if the application arrives more than thirty days after you signed. Plates and registration are a separate errand at a deputy registrar licence agency.
What they need to bring:
Ohio's emissions programme is called E-Check, it covers seven counties in the north-east, and it attaches to registration rather than to the title. Nothing about it stops you selling, and no test result changes hands at the assignment. It matters to a seller only as an answer to a buyer's question - and the answer depends on where the buyer lives, not where the car has been.
Registrants in an E-Check county can still take a multi-year registration of two to five years, and the test is still required for qualifying vehicles. Ohio BMV, new vehicle registration.
