Sign the title in the exact location your state's DMV specifies, and have the buyer sign their section at the same time
The title document itself tells you where to sign. Most states print "Seller's Signature" or "Owner's Signature" with a line next to it — that is where your signature goes. Some states use a box instead of a line. The critical step is signing in front of a notary public if your state requires it; about half of U.S. states do. Check your state's DMV website or call their title section to confirm whether notarization is mandatory where you live, because signing without it when it is required makes the title invalid and blocks the buyer from registering the car.
The buyer must also sign their section of the title at the same time, ideally in front of the same notary if one is needed. Many sellers and buyers meet at a notary's office, sign together, and walk out with a completed title ready to submit. If your state does not require notarization, you and the buyer can sign at home or anywhere else, but both signatures must be present on the same document before either of you submits it to the DMV.
Do not sign the title before you have agreed on price and the buyer has seen the car. Once you sign, you have legally transferred your ownership claim, and if the buyer then refuses to pay or the sale falls through, recovering the car or the money becomes difficult. Sign only when the transaction is final.
Key Takeaways
- Your state's DMV website lists the exact signature line and whether a notary is required; about half of states mandate notarization.
- Both you and the buyer must sign the same title document, ideally at the same time and in front of a notary if your state requires one.
- Signing before payment is received or before the buyer has fully committed leaves you vulnerable to a failed sale.
- Some states require you to fill in the odometer reading and sale price on the title before signing; check your state's form instructions.
What information goes on the title before you sign
Most state titles require you to fill in the sale price, the date of sale, and sometimes the odometer reading before you sign. These fields are usually labeled clearly on the form. The sale price is important because some states use it to calculate transfer tax, and the odometer reading protects against fraud — it creates a record of the car's mileage at the moment of transfer. If you leave these fields blank, the buyer may fill them in themselves, which creates a record you cannot verify.
Some states also ask for the buyer's name and address on the title itself, not just their signature. Fill in whatever your state's form requires before you meet the notary or the buyer. If you are unsure which fields are mandatory and which are optional, read the blank title form from your state DMV's website and read the instructions printed on the back — they specify what must be completed by the seller.
Whether you need a notary and how to find one
States that require notarization include California, Colorado, Connecticut, Delaware, Georgia, Hawaii, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, West Virginia, Wisconsin, and Wyoming. If your state is not on this list, notarization is optional but not required.
To find a notary, search online for "notary public near me" or call your bank — most banks offer notary services free to customers. UPS stores, FedEx locations, and some pharmacies also have notaries on staff, usually for a small fee between $5 and $15. When you call to schedule, tell the notary you need to sign a car title and ask whether they require an appointment or accept walk-ins. Bring your state ID and the unsigned title.
The notary will watch you sign, verify your identity, and then sign and stamp the title themselves. This process takes about five minutes. If the buyer is not present, you can sign your section and have the buyer sign theirs at a separate notary appointment, as long as both signatures end up on the same document before it is submitted to the DMV.
Signing the odometer statement and mileage disclosure
Many states require a separate odometer disclosure form or a statement on the title itself confirming the car's mileage at the time of sale. This is a federal requirement under the Odometer Act and protects the buyer from purchasing a car with rolled-back mileage. You must sign this statement under penalty of perjury, meaning you are confirming that the mileage you are reporting is accurate to the best of your knowledge.
If you do not know the exact mileage, write "Unknown" rather than guessing. Some states allow this; others do not. Check your state's DMV instructions. If the odometer is broken or does not work, note that on the form as well. The buyer needs this information to make an informed purchase and to protect themselves legally if the mileage is later found to be inaccurate.
What happens after both of you sign
Once both you and the buyer have signed the title, the buyer typically submits it to your state's DMV along with their registration process and proof of insurance. You do not submit it yourself unless your state's process is different. The buyer becomes the legal owner once the DMV processes the paperwork and issues a new title in their name.
Keep a copy of the signed title for your records, even after you have handed it to the buyer. If a dispute arises later — for example, if the buyer claims they never received the car or if there is a question about the sale price — your copy proves when and how the transfer occurred. Some states also send you a release of liability form to sign; this removes you from responsibility if the buyer gets into an accident or racks up parking tickets after the sale. Sign and return this form promptly if your state requires it.
Common mistakes to avoid when signing
Do not use a pen that is straightforward to erase, such as pencil or erasable gel pen. Use a ballpoint pen or permanent marker so that any alterations to the title after you sign are obvious. Do not sign in the wrong location — if the form says "Seller's Signature," sign on that line, not on the buyer's line or in the margin. Do not leave the sale price blank; fill it in with the actual amount you agreed on, even if you are selling the car for less than it is worth.
Do not sign before the buyer has paid you or before you have a written agreement about the sale. Do not cross out or white-out information on the title; if you make a mistake, ask your state DMV for a corrected form or a duplicate title. Do not assume the buyer will handle all the paperwork — confirm in writing who is responsible for submitting the title to the DMV and by what date.
Selling a car with a lien or loan still owed
If you still owe money to a bank or lender, the lender's name appears on the title as the lienholder. You cannot sign the title over to the buyer until the lien is removed. Contact your lender and ask for a lien release letter or payoff statement. This document confirms that once you pay off the loan, the lender will release its claim on the car.
Typically, you pay off the loan at closing using the sale proceeds from the buyer. The lender then sends a release document to the DMV, and the title is reissued without the lien. Some lenders allow the buyer and seller to meet at the lender's office so the payoff happens in real time. Confirm this process with your lender before you agree to sell the car, because it affects the timeline and the steps you and the buyer must follow.
Frequently Asked Questions
Can I sign the title before I receive payment?
You can, but it is risky. Once you sign, you have legally transferred ownership, and if the buyer does not pay or the sale falls through, recovering the car becomes complicated. It is safer to sign only after payment clears or at the exact moment the buyer hands you the money.
What if I make a mistake when signing the title?
Do not cross out or white-out the mistake. Contact your state DMV and request a duplicate or corrected title. Alterations to the title can make it invalid or raise questions during the buyer's registration process. A fresh form from the DMV is the safest option.
Do I need to sign the title if I am selling the car to a dealer?
Yes, but the dealer usually handles most of the paperwork. You will still sign the title in front of a notary if your state requires it. The dealer will guide you through their process, which may differ slightly from a private sale.
What if the buyer does not show up to sign at the notary?
You can sign your section alone, but the buyer must sign their section before the title is submitted to the DMV. Confirm with the buyer in advance that they will be present, or arrange for them to sign at a different time and location as long as both signatures end up on the same document.
Is the title valid if only I sign and the buyer does not?
No. Both the seller and buyer must sign for the title to be valid. If only you sign, the transfer is incomplete, and the DMV will not process the registration. Coordinate with the buyer to may support both signatures are on the document before either of you submits it.
