Common mistakes to avoid

Private-party side by side sales in Colorado go wrong when paperwork is rushed or incomplete. Avoid these costly errors:

• Incorrect or missing VIN. A VIN is exactly 17 characters with no letters I, O, or Q. Transcribing it wrong is the most common reason Colorado DMV offices reject title paperwork.
• Forgetting the odometer disclosure. Federal law requires an odometer disclosure on the title for vehicles under 20 years old. Leaving it blank — or writing "exempt" when the vehicle qualifies — can void the sale or trigger fines in Colorado.
• Missing or incomplete signatures. Both the buyer and seller must sign the bill of sale. In Colorado, an unsigned document has no legal weight. If there are co-owners, every owner listed on the title must sign.
• Not obtaining a lien release. If there is an outstanding loan on the side by side, the seller must obtain a lien release from the lender before the title can transfer. Buyers should verify the title is clear before handing over payment.
• Not notifying the Colorado DMV of the sale. Sellers who skip the DMV sale notification remain liable for parking tickets, tolls, and even accidents involving the side by side after it changes hands. File a release-of-liability form with Colorado as soon as the sale closes.
• Accepting personal checks or informal payment. Personal checks can bounce days after the sale. Use a cashier's check, money order, or verified electronic transfer for the full amount. Document the payment method on the bill of sale.

What happens after the sale

After the sale is complete, the seller should notify the Colorado DMV of the transfer to release liability for the side by side. The buyer must register the side by side and transfer the title within the deadline set by Colorado — failure to do so can result in late fees or penalties. Both parties should keep signed copies of the bill of sale and any supporting documents (odometer disclosure, lien release, etc.) for at least five years. The seller should cancel or transfer their insurance policy on the sold side by side, and the buyer must obtain valid insurance before driving or operating the side by side.
