No, Montana titles do not need to be notarized in the strict sense. Montana law requires the seller’s signature on the certificate of ownership to be formally acknowledged before the title can transfer, but a notary public is only one of five officials authorized to perform that acknowledgment. A county treasurer, deputy county treasurer, certain other elected officials authorized to acknowledge signatures, or an employee of the Montana Motor Vehicle Division can do it just as well.1Montana State Legislature. Montana Code 61-3-201 – Transfer of Interest Cancellation of Erroneous Certificate of Ownership or Registration
Who Can Acknowledge the Seller’s Signature
Montana Code 61-3-201 lists the officials who can witness and acknowledge the seller’s signature on a certificate of ownership:
- The county treasurer in the county where the transaction takes place
- A deputy county treasurer at that office
- Another elected official authorized to acknowledge signatures
- An employee of the Montana Motor Vehicle Division
- A commissioned notary public
Many sellers handle the acknowledgment at the county treasurer’s office during the same visit when the buyer submits the transfer paperwork. That approach keeps everything in one place and usually costs nothing extra. If you use an outside notary (available at many banks and shipping stores), Montana notaries may charge up to $10 per notarial act.2Montana State Legislature. Montana Code 1-5-626 – Fees for Notarial Acts Collection of Fees
Whoever performs the acknowledgment will verify the seller’s identity, so bring a valid government-issued photo ID such as a driver’s license or passport.
Fill the Title Out Before It’s Signed
The acknowledgment covers the seller’s signature, but the title itself has to be complete first. On the assignment section on the back, the seller records:
- The buyer’s full legal name and address, written out as it appears on their ID
- The odometer reading exactly as it appears on the dashboard at the time of sale
- The date of sale
- The actual purchase price, which the county uses to assess applicable fees
Accuracy matters. Montana treats alterations to a certificate of title as a felony, punishable by up to $5,000 in fines, up to 10 years in prison, or both.3Montana State Legislature. Montana Code 61-3-603 – Penalty for Alteration or Forgery of Certificate of Ownership or Certificate of Title Assignment Don’t use correction fluid, and don’t scratch out text. If you make a mistake, apply for a duplicate title through the county treasurer’s office instead of trying to fix the original.
The 40-Day Deadline for the Buyer
After the sale, the buyer has 40 days from the date of sale to apply for a new title and register the vehicle at the county treasurer’s office in their county of residence.4Montana State Legislature. Montana Code 61-3-220 – Certificate of Title Voluntary Transfer Duties The deadline covers motor vehicles, trailers, motorboats, snowmobiles, and other titled property.
Miss the 40-day window and a $10 late penalty is added to the transfer costs, payable before you can register the vehicle. Driving in the meantime also leaves the vehicle still titled in the seller’s name, which can create insurance and liability problems for both sides.
Submitting the Title and Paying the Fees
The buyer brings the acknowledged title (and any supporting documents, such as a bill of sale) to the county treasurer’s office in their home county. You can go in person or submit by mail, though in-person visits let you resolve paperwork issues on the spot.
At submission, expect to pay a title transfer fee, a registration fee, and county option taxes that vary by location. Registration fees depend on the age and type of vehicle. Montana has no general sales tax, but private vehicle sales may be subject to a separate use tax that the county treasurer’s office will calculate from the purchase price listed on the title.
Once the county treasurer processes the paperwork, the information is forwarded to the state and a new certificate of title is issued. The new title typically arrives by mail within four to six weeks. Keep a copy of the signed and acknowledged title during that window as proof the transfer is in progress.
If the Vehicle Has a Lien
When a lienholder’s name appears on the title, the lien has to be satisfied and released before the title can transfer. Montana accepts the Release of Security Interest or Lien form (MV37A), or a release on the lienholder’s letterhead that includes a complete vehicle description and the lien details.
Sellers should contact the lender for a payoff amount and arrange to clear the balance. Once satisfied, the lienholder sends the release documentation (along with the physical title, if they held it). Buyers should check the face of the title for any lien notations before handing over money, because an unresolved lien can block registration in the new owner’s name.
If Someone Signs on the Owner’s Behalf
When the seller or buyer cannot appear in person, Montana allows another person to sign using a power of attorney. The Motor Vehicle Division provides Form MV65 for this purpose. The person holding the power of attorney signs the title by writing the owner’s name, followed by their own signature and “POA” to show they’re acting in a representative capacity. The POA document goes along with the title at the time of the transaction.
Transfer on Death Designations
Montana vehicle owners can name a transfer-on-death (TOD) beneficiary directly on the certificate of title, so the vehicle passes outside of probate when the owner (or the last surviving joint owner) dies.5Montana State Legislature. Montana Code 61-3-226 – Certificate of Title Transfer on Death Definition After the owner’s death, the beneficiary presents proof of death and personal ID to the county treasurer or the MVD. A TOD designation gives the beneficiary no ownership rights while the owner is alive and does not override any lien that existed before death.
Mistakes That Delay a Transfer
A few common errors send people back to the counter:
- Using correction fluid or scratching out text on the title. Any visible alteration can invalidate the document and triggers the forgery/alteration statute. Apply for a duplicate instead.3Montana State Legislature. Montana Code 61-3-603 – Penalty for Alteration or Forgery of Certificate of Ownership or Certificate of Title Assignment
- Submitting a title that was signed but never acknowledged by one of the five authorized officials. The county treasurer will not process it.
- Leaving the odometer reading blank or entering an estimate. Federal law requires an accurate mileage statement for most vehicles under a certain age.
- Missing the 40-day deadline, which adds a $10 late penalty and can complicate insurance coverage.4Montana State Legislature. Montana Code 61-3-220 – Certificate of Title Voluntary Transfer Duties
- Skipping the lien check. Buying a vehicle without confirming the title is clear can leave you unable to register it.
Fill out the assignment section cleanly, have the seller’s signature acknowledged by any of the five authorized officials, and get the paperwork to the county treasurer within 40 days. That covers the whole transfer.
