Puerto Rico does not transfer a normally titled private vehicle through a generic bill of sale alone. The buyer and seller formalize the transfer on the back of the original Certificate of Title or, in qualifying cases, through a sworn declaration, and the new buyer must file the completed transfer with DTOP/CESCO.

For a standard private transfer, the new owner must file the formalized transfer within 15 days. The buyer also has 10 business days to identify an existing plate that will be used or request a new plate. Filing the ownership transfer late adds $10 for each month or fraction of a month after the 15-day period.

Puerto Rico Uses the Back of the Title to Formalize the Sale

Puerto Rico’s Vehicle and Traffic Law provides that the transfer is authorized through the signatures of the registered owner and the buyer on the reverse of the Certificate of Title.

The buyer’s address must also be entered.

CESCO’s normal Traspaso por dueño checklist requires:

• Original vehicle permit when current.

• Certificate of Title.

• Formalized or sworn transfer.

• Lien payoff letter when applicable.

• Required revenue stamp and voucher.

Current official requirements: CESCO — Vehicle Transfer Requirements.

A separate private bill of sale remains useful for documenting the transaction, but it does not replace the required title transfer.

Florida uses a different approach through a combined Notice of Sale and Bill of Sale form. See KarKiosk’s Florida Bill of Sale guide.

Puerto Rico Private Vehicle Sale Rules

The Standard Transfer Must Be Sworn or Properly Authorized

Puerto Rico’s normal CESCO process refers to the juramentación del traspaso.

The transfer can be completed on the back of the Certificate of Title.

Where the transaction instead proceeds through a sworn declaration signed by the transferring owner and acquiring owner, CESCO requires additional steps.

The basic rule is therefore more formal than simply having both parties sign a generic bill of sale.

The sale record and title-transfer document should agree on:

• Buyer.

• Seller.

• Vehicle.

• VIN.

• Date.

• Price.

• Any financing or lien status.

The Buyer Has 15 Days to File the Completed Transfer

Puerto Rico law states that once the transfer document has been formalized, the new owner must file it with the Department within 15 days.

If the buyer files after that period, the law adds:

$10 for each month or fraction of a month that has elapsed.

The calculation uses the date the transfer was formalized.

This is a filing deadline, not an invitation to leave the vehicle in the seller’s name for several weeks.

The buyer should complete the CESCO process as soon as the transaction is finalized.

The current statutory transfer provisions appear in Puerto Rico Vehicle and Traffic Law — Article 2.41.

The Buyer Also Has a 10-Business-Day Plate Rule

Puerto Rico’s plate rules operate on a shorter clock.

The buyer has 10 business days from acquisition to:

• Notify the Secretary which valid plate the buyer will use; or

• Request a plate if the buyer does not already have an eligible one.

When a financed vehicle is involved, the buyer must have a plate or apply for one within the same 10-business-day period and cannot operate the vehicle on public roads without a plate.

The plate deadline and the 15-day transfer-filing deadline are separate.

A Normal Owner Transfer Has $17 in Listed Stamp and Voucher Charges

CESCO’s current Traspaso por dueño checklist lists:

• Internal Revenue stamp code 5120: $15.

• Internal Revenue voucher code 0842: $2.

That produces $17 in the standard listed transfer stamp/voucher charges.

Other amounts can apply when:

• A lien must be cancelled.

• The title is missing.

• The vehicle requires inspection.

• The transfer uses a sworn-declaration route.

• Other fines or recorded obligations exist.

Do not treat $17 as the complete cost of every vehicle transaction.

A Sworn-Declaration Transfer Costs More

When the transfer was not perfected on the Certificate of Title and the parties use a sworn declaration, the vehicle must undergo additional record verification and inspection.

CESCO currently lists additional items for that route:

• $6 revenue stamp.

• $2 voucher.

• $30 CESCO inspection.

Those special charges are in addition to the normal transfer items listed by CESCO.

A straightforward title-back transfer is therefore simpler than trying to reconstruct the ownership transaction later.

Eligible Vehicles Can Be Transferred Through CESCO Digital

Puerto Rico allows qualifying private transfers through the CESCO Digital application.

Current eligibility requirements include:

• Vehicle has no lien.

• Vehicle is paid off.

• Vehicle was registered after July 11, 1987.

• Seller has the original title.

• Buyer and seller both use CESCO Digital.

Current digital guidance: CESCO Digital — Transfer FAQ.

The seller starts the transaction in the app and identifies the buyer.

The buyer accepts the transfer.

The seller then reviews the charges and completes payment.

Afterward, the buyer selects a CESCO location, receives an appointment, and brings the signed original title to collect the updated Certificate of Title.

The Digital Process Changes the Signature Handling

For an eligible digital transfer, the buyer completes the transfer section on the back of the original title.

CESCO instructs the buyer to write:

“CESCO DIGITAL DTOP”

in the area reserved for the notary or authorized official.

The buyer then brings:

• Signed original title.

• Transfer receipt.

• Current photo identification.

• Vehicle licence when the marbete remains current.

This is different from simply emailing a digital bill of sale.

The original title is still part of the process.

The Seller Does Not Give the Buyer the Seller’s Plate

Puerto Rico law treats the plate as belonging to the registered owner rather than automatically following the sold vehicle.

The previous owner keeps the plate for possible use on another vehicle of the same category or classification.

If the former owner does not remain the owner of another motor vehicle, trailer, or semitrailer, the law requires the plate to be returned according to the applicable procedure.

The new buyer either:

• Uses an eligible plate already belonging to the buyer; or

• Requests a new plate.

When the buyer has no plate, a new plate is issued in the buyer’s name after the applicable process.

Georgia also separates the sale record from the state’s actual title-transfer and tax process. See KarKiosk’s Georgia Bill of Sale guide.

A Transfer Does Not Cancel Existing Liens

Puerto Rico law states that transferring the vehicle does not automatically cancel or modify liens already attached to it.

CESCO requires a payoff letter when a conditional-sale or movable-property lien must be cleared.

Depending on when the lien was recorded, a revenue voucher may also be required.

Do not pay the seller in full until the lien-release process is clear.

The bill of sale cannot erase financing recorded against the vehicle.

Vehicles Registered Before July 11, 1987 Need Extra Paperwork

CESCO identifies an additional process for older vehicles registered before July 11, 1987.

The applicant must present the vehicle licence and request the Certificate of Title.

CESCO currently lists:

• $11 revenue stamp.

• $2 revenue voucher.

These older vehicles also do not qualify for the ordinary CESCO Digital transfer route.

What If the Seller Disappears or Refuses to Complete the Transfer?

Puerto Rico has an ex parte transfer process for situations where the registered owner disappears or refuses to sign after the sale.

CESCO can require:

• Sworn declaration explaining the circumstances.

• Proof that the buyer attempted to contact the registered owner.

• Current vehicle permit or certification.

• Ownership and lien information.

• CESCO inspection.

• Additional stamps and vouchers.

This process is more complicated and more expensive than completing the title correctly at the time of sale.

A signed generic bill of sale can help show what occurred, but it does not automatically guarantee approval of an ex parte transfer.
