New Mexico Vehicle Bill of Sale

After purchasing a vehicle in a private sale, you must register it with the New Mexico motor vehicle agency within 30 days for buyer (90 days if new resident). Missing this deadline can result in late fees or penalties.

Bring the signed certificate of title, your bill of sale, proof of insurance meeting New Mexico minimum requirements, and a valid driver's license or state ID. The purchase price on your bill of sale is typically used to calculate sales or use tax.

Inspect the vehicle before paying, verify the VIN on the title matches the vehicle, and confirm the odometer reading is accurately disclosed on both the title and bill of sale. Private sales in New Mexico are generally considered as-is unless the seller provides a written warranty.

Before accepting payment, confirm you hold a clear title with no undisclosed liens. Complete a bill of sale documenting the transaction and sign the title assignment with accurate odometer disclosure for vehicles under 20 years old.

Seller should notify MVD after sale. In most cases, remove your license plates from the vehicle before the buyer takes possession.

Provide the buyer with the signed title, a copy of the bill of sale, and any maintenance records you agreed to share. Keep your own copy of the bill of sale as proof the vehicle was sold.

When you register the vehicle, New Mexico typically assesses tax based on the purchase price listed on your bill of sale. If the stated price appears significantly below fair market value, the licensing office may use a standard book value instead.

Private party sales are subject to the same tax rules as other acquisitions in most cases. The bill of sale purchase price is the primary documentation used at registration, which is why an accurate, complete document matters.

Our bill of sale clearly states the purchase price, giving New Mexico licensing officials the documentation they expect.

The certificate of title — not the bill of sale alone — is the primary document that transfers ownership. The seller signs the title assignment; the buyer submits it to the New Mexico motor vehicle agency along with the bill of sale and other required documents.

Buyers must complete registration within 30 days for buyer (90 days if new resident). Required documents typically include the assigned title, bill of sale, proof of insurance, and valid ID.

New Mexico may require additional official forms. Form MVD-10009 available; generic forms accepted. A generic bill of sale supplements but may not replace those forms.

Seller provides: signed certificate of title with odometer disclosure, bill of sale, and any lien release if applicable.

Buyer brings to registration: assigned title, bill of sale, proof of New Mexico insurance, valid identification, and payment for registration fees and applicable taxes.

Both parties should retain signed copies of the bill of sale. Documents from billandsale.com include a footer noting the generation date and that the form is not an official DMV document.
