What Documents Do You Need to Sell a Junk Car in Missouri?
Getting your documents right before pickup day saves time and makes the whole process go smoothly. Here's exactly what Missouri and Illinois require — plus what to do if you're missing something.
What Missouri Requires
Missouri Certificate of Title: This is the most important document. It must be in your name (or you must have legal authority to sign). Sign on the 'Seller' line exactly as your name appears on the title. Fill in the odometer reading if required.
Valid Government-Issued Photo ID: Driver's license, state ID, or passport. The name on your ID must match the name on the title. If the name doesn't match (marriage, name change), you may need supporting documentation.
That's it for a standard Missouri transaction. Two documents.
What Illinois Requires
Illinois Certificate of Title: Same concept — must be signed on the seller's line with the odometer disclosure completed.
Valid Photo ID: Illinois driver's license or state ID preferred. Name must match the title.
Illinois also requires the seller to notify the Secretary of State within 7 days of the sale to protect yourself from future citations. This protects you from future parking tickets or citations on a vehicle you no longer own.
What to Do If You Don't Have the Title
Call us first. Depending on your vehicle's year, make, and state, there is often a straightforward path to selling without a title — no runaround, just a quick answer.
Missouri has several legal pathways for junk vehicles without a clean title. For very old vehicles, a junk vehicle affidavit may allow the transaction to proceed. We handle these situations every week and will confirm your options in one phone call.
Illinois sellers in the Metro East — call us before doing anything. We work with St. Clair and Madison County sellers regularly and know exactly what documentation your situation requires.
Co-Owner on the Title?
If the title has two names connected by 'AND,' both owners must sign. If connected by 'OR,' either owner can sign alone.
If a co-owner is deceased, the surviving owner may need to go through a small estate process. Call us — we handle inherited vehicle situations regularly.
Lien on the Title?
A lien means a bank or lender has a legal interest in the vehicle. You cannot transfer the title until the lien is released. Contact your lender and request a lien release — for a totaled or junk vehicle, most lenders process this quickly.
Once the lien is released (usually a letter or stamp on the title), you can proceed with the sale.
Day-of Checklist
Signed title (seller's signature + odometer disclosure)
Valid photo ID
All personal belongings removed from the vehicle
Keys (preferred, but not always required for towed vehicles)
Missouri plates removed — you may keep Missouri plates and transfer them to another vehicle
Frequently Asked Questions
Do I need to remove my Missouri license plates before selling?
Yes — Missouri plates belong to you, not the car. Remove them before or at pickup. You can transfer them to another vehicle or surrender them to a license office for a refund of unused registration fees.
What if my title shows a lien from a loan I already paid off?
If the lien is paid but the title still shows it, contact your lender for a lien release letter. Most lenders will issue one quickly. Some Missouri titles include a perforated lien release section — check yours.
Can my spouse sign if the car is in my name?
Only if they have legal authority (power of attorney). Otherwise, the person whose name is on the title must sign.
Do I need the car's registration to sell it for junk?
No — registration is not required to sell a vehicle for junk in Missouri or Illinois. The title is what matters for the legal transfer.
