New Mexico: Private-Party Vehicle Title Transfer Requirements

Requirements one by one

The endorsed title is the transfer instrument

New Mexico moves ownership through the certificate of title. Section 66-3-102
requires the owner to "endorse an assignment and warranty of title upon the
certificate of title," list all liens or encumbrances, and "deliver the
certificate of title to the purchaser or transferee at the time of delivering
the vehicle." The title itself carries the spaces for that assignment and
warranty and for releasing a lien (§ 66-3-10(E)). A certificate of title is
"prima facie evidence of the ownership" (§ 66-3-12), so the assigned title, not
a receipt, is what the buyer needs.

If the vehicle has co-owners joined by "and," each must sign. A recorded lien
must be cleared before the new title issues: the lienholder can sign the
release area on the title, use MVD Form 10041, or provide a notarized release on
its letterhead.

Ordinary signatures are not notarized

New Mexico does not require a notary or witness for the ordinary title
assignment. The statute governing total-loss conveyances confirms the point in
the opposite direction — those documents "shall not require a notarized
signature and may be signed electronically" (§ 66-3-10.1(C)). Notarization is
reserved for a power of attorney signing on the owner's behalf and for a lien
release given on a lienholder's letterhead.

A bill of sale is not the transfer instrument. Between individuals, MVD's Bill
of Sale (Form MVD-10009) is used mainly to complete the transfer "when the
assignment on the reverse side is incomplete" or there is no room left on the
title. It records the year, make, VIN, sale price, and each party's name,
address, and signature — but the endorsed title and the buyer's MVD application
still control.

Odometer disclosure rides the transfer document

Section 66-3-101(A) requires the person making the transfer to "sign and
record on the document evidencing the transfer of the vehicle the actual
mileage of the vehicle." MVD requires an odometer statement on every title
transaction except off-highway vehicles, and it may sit on the title
assignment, the bill of sale, Form 10009, or the Form 10001 application. The
federal odometer rule exempts older vehicles by age; salvage or nonrepairable
branding is a separate process under § 66-3-10.1 and is outside an ordinary
transfer.

Plate stays with the seller; the record gets marked

New Mexico is a plate-to-owner state. On a sale the "registration of the vehicle
shall expire," and the previous owner must notify the division of the sale, its
date, and the buyer's name, address, and vehicle description (§ 66-3-101(A)).
The seller "shall remove and retain the registration plate" and has 30 days to
reassign it to another vehicle of the same class or surrender it to be destroyed
(§§ 66-3-101(B), 66-3-104(B)). You can mark the vehicle sold through MyMVD or
file the Notice of Vehicle Sold (Form 10048). That notice updates the record; it
is not itself the transfer of ownership.

The buyer's clock and costs

The buyer must apply before driving and within 30 days of the sale. Section
66-3-103(A) says the transferee, "before operating or permitting the operation
of the vehicle," shall present the assigned title and apply for a new title and
registration, and § 66-3-107(A) fixes the 30-day window from the date of sale.
The application (Form 10001) needs proof of a New Mexico residence address
(§ 66-3-4(A)), any lienholder information, an insurance affirmation, and the
fees. New Mexico charges a 4% motor vehicle excise tax on "the price paid for
the vehicle," with trade-in allowances deductible (§§ 7-14-3, 7-14-4).

Inspection, insurance, and driving

A vehicle already titled in New Mexico needs no VIN inspection; that step
applies to out-of-state titles (§ 66-3-4(B)). Emissions testing is required only
for vehicles registered or commuting in Bernalillo County (§ 66-3-7.1).
Registration requires an affirmation of financial responsibility under the
Mandatory Financial Responsibility Act, with minimum coverage of $25,000 per
person, $50,000 per accident, and $10,000 for property damage. Because the
registration expired on the sale and § 66-3-103(A) bars operating before
applying, the buyer cannot lawfully drive the car home on the seller's plate.

Late filing and rejection

Missing the 30-day window subjects the buyer to a $20 penalty (§ 66-3-107(E))
and is a penalty assessment misdemeanor (§ 66-3-103(B)). Driving on the expired
registration adds a penalty of the greater of $10 or, after 31 days, 75% of the
registration fee, and the vehicle can be seized (§ 66-3-19(E)). MVD rejects an
application that is missing a lien release, a signature, or that shows
alterations or discrepancies, and gives a 10-day window to cure (Form 10282).

What trips people up

• Driving away on the seller's plate. The plate stays with the seller and
  the registration expires at the sale, so the buyer needs a title-and-
  registration application (and, in practice, a plate) before driving.
• Treating a bill of sale as the title. MVD's bill of sale mainly fills a
  gap when the title's assignment area is incomplete; the endorsed title is what
  transfers the car.
• Forgetting the seller's notice. Marking the vehicle sold with MVD does not
  complete the buyer's transfer, but skipping it leaves the sale unrecorded on
  the seller's account.
• Overlooking the excise tax. The 4% motor vehicle excise tax is charged on
  the price paid, not a separate sales tax; trade-in allowances reduce the base.

Common questions

Does a New Mexico bill of sale transfer the car by itself?
No. Section 66-3-102 ties the transfer to the endorsed, delivered title. MVD's
bill of sale is used mainly to complete a transfer when the title's assignment
area is incomplete.

Do the title signatures need to be notarized?
Not for the ordinary assignment. Notarization is needed only for a power of
attorney signing for the owner or a lien release given on a lienholder's
letterhead.

How much is the tax on a private used-car purchase?
A 4% motor vehicle excise tax on the price paid, with trade-in allowances
deductible (§ 7-14-4). It is a distinct excise tax, not the general sales tax.

Can I keep my old plate for my next car?
Yes. New Mexico assigns the plate to the owner. You remove and keep it and have
30 days to move it to another vehicle of the same class or surrender it.
