Do you need a notary to transfer a car title in Ohio or Texas?

Selling or gifting a car is one of the most common everyday reasons people search for a notary, and the answer is completely different in the two states we cover. This page summarizes the Ohio BMV, Ohio Revised Code, TxDMV and Texas Comptroller guidance, checked Nov 10, 2026 (America/New_York). Not legal advice; your county title office has the final word on its paperwork.

Quick answer

Situation	Ohio	Texas
Private sale, paper title	Yes. The seller fills in the assignment on the back of the title and signs it in front of a notary or a deputy clerk at a title office. All owners must sign unless a notarized power of attorney is used.	No. TxDMV says title assignments, bills of sale and odometer disclosures haven’t needed notarization since April 1, 1990. The buyer files the signed title and Form 130-U at the county tax office.
Private sale, electronic title	Yes. Instead of the back of a title, the seller completes page 1 of form BMV 3770 and has it notarized; the buyer completes and notarizes page 2. Only for Ohio-resident buyers and ordinary motor vehicles.	Same as above: no notary for the standard transfer.
Gift to a family member	The title assignment still has to be notarized like any transfer.	Yes. To pay the $10 gift tax instead of sales tax, donor and recipient sign Form 14-317, sworn before a notary (any state, or an authorized online notary) or a county tax office employee.
Owner has died, no probate	Ask the county title office; Ohio has separate survivorship and transfer-on-death paths.	Yes. The Affidavit of Heirship for a Motor Vehicle (VTR-262) needs all signatures notarized.

Ohio: why the notary step matters

Ohio law requires the title application to be sworn before a notary or another officer who can give oaths (Ohio Rev. Code §4505.06(A)(1)), and the seller swears to the true selling price and odometer reading (§4505.06(C)).
Fill everything in before the seller signs. County title offices tell sellers to enter the buyer’s full name and address, date, price and mileage, then sign in front of the notary. Belmont County warns not to fill in any part of the assignment except in front of a notary.
Don’t cross out or white-out anything. An altered Ohio title can be voided, and the seller may need a duplicate or an affidavit of correction from the title office.
The seller doesn’t have to go to the title office. Franklin County says the seller can sign before a notary and hand the title to the buyer, who finishes the transfer.
File within 30 days. Late applications get a $5 fee (§4505.06(A)(6)). The buyer pays sales tax on the purchase price plus the county title fee (Cuyahoga County lists $18 for an original title).
Someone signing for a seller needs the original Power of Attorney for Certificate of Title (form BMV 3771). A minor seller needs form BMV 3751.
Notary cost: Ohio caps the notary’s fee at $5 per notarial act; anything else a mobile notary charges is travel, which has to be agreed in advance. See the Ohio fee guide.

Texas: when a notary is actually needed

For a plain private sale, the seller gives the buyer the signed title (with date of sale and odometer reading) and Form 130-U. The buyer’s signature on the 130-U must be original; the seller’s may be a copy or fax and isn’t required when the seller isn’t a dealer.
The buyer has 30 days to title the car at the county tax office. In Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall and Tarrant counties (among 18 statewide), an emissions inspection is needed first.
A notary is needed for the gift affidavit (Form 14-317) and the no-probate heirship affidavit (VTR-262). Eligible gift relationships include spouse (separate property only), parents, children, siblings, grandparents and grandchildren, in-laws in those roles, and guardians.
You can skip the notary on Form 14-317 if both people sign in front of a county tax office employee. A mobile notary is mainly worth it when one party can’t get to the tax office.
Notary cost: Texas caps notary fees by act; travel is extra and should be quoted up front. See the Texas fee guide.

Before you book a mobile notary for a title

Bring the original title (Ohio title offices don’t accept photocopies) or the BMV 3770 / 14-317 form, unsigned.
Every signer needs an unexpired government photo ID. See what to bring.
If there’s a loan on the car, get the lien release first; Franklin County says an active lien must be cancelled before transfer.
Ask whether the notary has done vehicle titles before. Some Cleveland-area mobile notaries list titles and BMV forms as a specialty.

Online notarization: Texas’s gift affidavit explicitly accepts a Texas-authorized online notary. For an Ohio title, check with the county title office before using an online notary, since they handle a paper original.
