On a vehicle title — the document many people still call a pink slip — both the seller and the buyer sign on the back, in separately labeled assignment sections. The seller signs in the “Assignment of Title by Owner” block; the buyer signs in the “Assignment of Title by Purchaser” block. Each block has its own signature line, printed-name line, address line, and date field. Knowing where to sign a pink slip matters because signing in the wrong place can void the transfer section entirely and send you back for a duplicate title.
Finding the Right Lines on the Back
Every state designs its own title, but the layout follows the same pattern. The front shows the vehicle description, the current owner, and any lienholder. The back is where ownership changes hands. Look for the headings that call out “Owner” and “Purchaser.” Read the labels before you pick up a pen. Sellers sometimes sign on the buyer’s line out of habit, and that one slip can invalidate the whole assignment.
You’ll also see a section labeled something like “Reassignment by Dealer.” That area is for licensed dealers reselling a vehicle. Private sellers and buyers should leave it blank.
What the Seller Fills In
The seller’s section typically asks for:
- Signature
- Printed name
- Mailing address
- Date of sale
- Sale price
- Odometer reading (in the same area or immediately adjacent)
All of this goes in the seller’s assignment section only. By signing, you confirm that you own the vehicle and are transferring ownership to the buyer. Discrepancies between what you write and the actual facts of the sale can create civil liability. The sale price matters because many states use it to calculate the buyer’s sales tax, so understating it to help the buyer save money can create problems for both of you.
What the Buyer Fills In
The buyer’s section is shorter. You sign, print your name, enter your address, and date the document. Your signature confirms you’re accepting the vehicle and acknowledging the seller’s disclosures, including the odometer reading.
Some states don’t require the buyer to sign the title itself during the transfer, collecting the buyer’s signature on a separate registration application instead. Check your state’s motor vehicle agency website before the transaction so you know which documents need a signature at the point of sale versus at the registration office.
When Two Names Are on the Title
The small word between the owners’ names changes who signs. If the title reads “John Smith or Jane Smith,” either owner can sign alone. If it reads “John Smith and Jane Smith,” both owners must sign. This is where a lot of private sales stall: one owner signs, the buyer drives away, and the motor vehicle office rejects the paperwork because the second signature is missing.
Before buying a vehicle with two names on the title, look at the conjunction. If it says “and,” insist that both owners sign at the sale or that the absent owner has already signed. Chasing down a missing signature later means tracking down someone who may have moved or become uncooperative.
When one co-owner has died, the surviving owner on an “or” title can usually transfer the vehicle by presenting a death certificate alongside the signed title. On an “and” title, the process typically runs through the deceased owner’s estate.
Signing When a Lien Is Still Listed
If the title shows an active lien, a lender has a financial interest in the vehicle. In many states, the lienholder physically holds the title until the loan is paid off, so the seller may not have the document in hand at all.
To sell, the seller needs to pay off the remaining balance. The lender then issues a lien release, either stamped on the title or provided as a separate document. In states that hold titles electronically, the lender releases the lien through the state’s system and the state mails a clean title to the owner.
Never accept a title that still shows an active lien without seeing a lien release from the lender. If you register the vehicle and the lien hasn’t been formally released, some states will carry it forward onto your new title.
Signing for Someone Else
Power of Attorney
If the owner can’t be present, a person holding a valid power of attorney can sign. The agent signs the owner’s name and then adds their own name with “POA” or “Power of Attorney” beside it. Most states require you to submit the original or a certified copy of the POA document along with the title. A general power of attorney usually works, though some states have a motor-vehicle-specific POA form.
Trusts and Business Entities
When a vehicle is titled to a trust, the trustee signs on the trust’s behalf. The typical format is “Jane Smith, Trustee of the John Doe Trust.” Whether one trustee can sign alone or all trustees must sign depends on the trust document itself. If the trust names multiple trustees joined by “and” without language letting any one act alone, expect the motor vehicle office to require every trustee’s signature.
For vehicles owned by an LLC, corporation, or other business, an authorized officer or member signs and includes their title with the company, for example: “Jane Smith, Managing Member, Smith Enterprises LLC.” The motor vehicle office may ask for documentation proving the signer’s authority, such as articles of organization or a corporate resolution.
After the Owner’s Death
Who signs after death depends on whether the title named a transfer-on-death beneficiary, whether the estate goes through probate, and your state’s small-estate rules. A named beneficiary can often claim the vehicle with the title, a death certificate, and a state-specific affidavit. Heirs without a beneficiary designation may use a small estate affidavit (for estates under a certain dollar threshold) or go through probate to get authority to sign. Several states require heirs’ signatures on the affidavit of heirship to be notarized.
Odometer Disclosure on the Signature Page
Federal law requires the seller to disclose the vehicle’s mileage in writing at the time of sale, and that disclosure is made on the title itself in a section asking for the current reading, whether the reading is accurate, and the seller’s certifying signature.1Office of the Law Revision Counsel. 49 USC Ch. 327 – Odometers Some states use a separate odometer disclosure form instead of, or in addition to, the title.2eCFR. 49 CFR Part 580 – Odometer Disclosure Requirements
If the odometer has rolled over, been replaced, or is known to be inaccurate, check the box indicating the true mileage is unknown. Leaving it blank or checking “accurate” when you know better is fraud. Certain vehicles — generally those more than ten model years old, trailers, and heavy vehicles over 16,000 pounds — are exempt from the federal disclosure requirement.3eCFR. 49 CFR 580.17 – Exemptions Even on an exempt vehicle, writing the correct mileage protects both sides.
States That Require a Notary
Roughly a dozen states require one or both signatures on the title to be notarized before the transfer is valid. In some, only the seller’s signature needs notarization; in others, both seller and buyer must sign before a notary. A handful make notarization optional but recommended.
If your state requires it, do not sign the title before you’re in front of the notary. A notary has to witness the signature being made and can’t notarize a document that was pre-signed. State-set notary fees are generally modest, with most states capping the charge somewhere between $2 and $15 per signature. Check with your state’s motor vehicle agency ahead of the sale so you aren’t hunting for a notary at the last minute.
If You Sign in the Wrong Place or Make a Mistake
Never use white-out, correction tape, or an eraser on a title. Any of those will void the document, and the motor vehicle office will reject it on sight. For a minor error like a misspelled name, the standard fix in most states is to draw a single line through the mistake, write the correct information nearby, and have the person who made the error initial the correction. Some states also want a notarized statement explaining the change.
If the title is too marked up to salvage, or if a seller signed on the buyer’s line and voided the assignment, the current owner — not the buyer — has to apply for a duplicate title. Duplicate fees vary by state but typically fall in the $10 to $30 range, and processing can take a few days to a few weeks by mail. Buyers should refuse any title with visible alterations or white-out, because the motor vehicle office will reject it and leave the buyer waiting for a replacement.
Gift Transfers
When you gift a vehicle instead of selling it, you still sign the title in the seller’s assignment section. The difference is in the sale price field: most states have you enter “$0” or “gift.” Many states also require a separate gift affidavit, signed by both the giver and recipient, certifying that no money or other consideration changed hands. That affidavit is what exempts the transfer from sales tax in states offering a gift exemption, though the exemption is often limited to immediate family.
The signature placements don’t change for a gift. The giver fills in the seller’s section; the recipient fills in the buyer’s section. Skipping the gift affidavit or failing to write “gift” on the title can result in the recipient being charged sales tax based on the vehicle’s fair market value.
After You Sign
Many states require (or strongly encourage) sellers to file a notice of transfer or release of liability with the motor vehicle agency within a few days of the sale. Until that notice is on file, the seller can be held responsible for parking tickets, toll violations, or accidents involving the vehicle. Keep a copy of the signed title and any bill of sale. Buyers usually have 15 to 30 days to register the vehicle and pay sales tax before late fees kick in.
