Why digital change of ownership matters in a professional sale
A dealership that sells fifteen cars a month generates fifteen changes of ownership. If each one requires a trip to the Traffic Office, manual handling of documentation and telephone follow-ups with the agency, the administrative burden is considerable. And every day that a sold car remains in the dealership's name in the DGT register is a day of exposure to fines, insurance incidents or unpaid IVTM (municipal road tax) bills that arrive in the seller's name even though the vehicle is no longer theirs.
Digitalising the procedure does not eliminate documentary responsibility, but it does drastically reduce the time and cost per transaction when the process is well-structured. A change of ownership that previously required two visits and several days can be resolved in hours if the documentation is in order and the appropriate channel is used.
The three ways to manage the change of ownership
Option 1: DGT Portal (miDGT / electronic office)
The DGT allows you to process the change of ownership directly through its electronic office. The main requirement is to have a digital certificate or access with Cl@ve. The buyer (or the dealership if managing the procedure on their behalf) accesses the portal, uploads the documentation, pays the fee online and the DGT processes the change.
This is the most economical option but the least efficient for medium or high volumes. The interface is not optimised for batch management, and any documentary issue requires resolving directly with the DGT.
Option 2: Traditional agency (Gestoría)
A gestoría processes the change of ownership with a power of attorney from the client or with signed documentation. The dealership delivers the documents, the gestoría manages the procedure in person or electronically, and returns the registration document with the new owner's details.
The advantage is that the agency takes responsibility for the process. The disadvantage is the cost (between 60 and 120 euros per transaction depending on the agency and complexity) and the lack of real-time visibility on the status of each file.
Option 3: Platform with API integration with the DGT
Some management platforms for dealerships have direct integration with the DGT or with digital agencies connected to the Traffic system. This allows starting and tracking the procedure from the dealership's own management software, without leaving the platform and without physical paper.
For dealerships with more than five or six transactions per month, this is the most efficient option: the cost per transaction drops, tracking is in real-time, and the documentation remains central-focused in the vehicle's file.
To see how a DMS can integrate this procedure into the workflow of each transaction, check out the guide on what is an automotive DMS and how to choose the right one.
What documentation you need in each case
The basic documentation remains the same regardless of the channel you use. It only varies who provides it and how it is delivered.
Documents provided by the seller (dealership):
Original registration certificate of the vehicle. Technical sheet. Sale and purchase agreement signed by both parties. If the vehicle has active charges, the document confirming cancellation of the charge. If the vehicle was temporarily deregistered, the document showing it has been re-registered.
Documents provided by the buyer:
Valid DNI or NIE. Proof of payment of the ITP (property transfer tax, form 620 or 621 depending on the autonomous community), except if the buyer is a professional who registers for VAT, in which case another regime applies. In operations where the dealership issues an invoice with VAT, the private buyer does not pay ITP: the transfer process is done based on the invoice. To clarify when ITP applies and when it does not, you can consult the guide on what is ITP in car sales and when it applies.
For the online procedure, you also need:
Digital certificate or Cl@ve access of the owner carrying out the procedure (or power of attorney if managed by a third party). In some autonomous communities, the proof of ITP must be presented in digital format with a verification code.
How much it costs: fees, agencies and platforms
DGT Fee: the official fee for changing ownership is 55.70 euros (rate in force in 2026). It is paid regardless of the channel used to process it.
Traditional agency: between 60 and 120 euros per transaction, depending on the agency, the complexity of the procedure and if there are complications. In some areas or with agencies specialised in automotive matters, a flat rate can be negotiated for volumes.
Digital platforms with DGT integration: the cost varies depending on the provider. Some charge per transaction (between 25 and 50 euros in addition to the DGT fee), others include it in the monthly software fee. For dealerships with volume, the cost per transaction is usually lower than that of a traditional agency.
The total cost per transfer for a dealership using a conventional agency ranges between 115 and 175 euros per transaction (fee plus honorarium). Multiplied by fifteen monthly operations, this is between 1,725 and 2,625 euros a month just in managing transfers.
Who processes the transfer: the dealership or the buyer
Legally, the obligation to process the change of ownership falls on the buyer: they have 30 business days from the signing of the contract to complete the process. However, in practice, many dealerships manage the transfer on behalf of the buyer, especially when they include it as a service within the sale or when they work with their own agency.
To understand the consequences of not notifying the sale, you can review the article on complaints against dealerships before the DGT.
When the dealership manages the procedure, they control the process and reduce the risk of the buyer delaying it or doing it incorrectly. When left in the hands of the buyer, they lose that visibility and may find that the car is still in their name weeks after the sale.
If you choose to leave the procedure to the buyer, notifying the DGT of the sale (which is indeed the seller's obligation) detaches you register-wise even if the name change hasn't been completed yet.
Notification of sale: the procedure that many forget
The notification of sale is different from the change of ownership and many dealers confuse or ignore it. The seller is obliged to notify the DGT that they have sold the vehicle, regardless of whether they manage the change of ownership or not.
This procedure can be done online at the DGT's electronic office in minutes and is free of charge. Once the sale is notified, if the buyer incurs a fine or incident before completing the name change, the dealership remains registration-protected: the DGT has proof that the vehicle was transferred.
Without a notification of sale, the dealership may receive fines, notifications of expired MOTs (ITV) or IVTM bills for a car they already sold, and will find it harder to prove that the responsibility is not theirs. To see how this procedure fits into the mandatory documentation of each transaction, you can consult the guide on mandatory documentation in each sale and purchase transaction.
Common mistakes and how to avoid them
Not checking that the vehicle is free of charges before starting the process. An active embargo or a retention of title blocks the change of ownership until they are cancelled. Checking this before selling, and not after the procedure gets blocked, saves weeks of hassle. To see how to detect and resolve these situations, you can consult the guide on how to know if a car has outstanding charges.
Not having paid the ITP before starting the procedure. Without proof of payment of the ITP (when applicable), the DGT will not process the change of ownership. If the buyer has not paid the tax, the process is put on hold until they do.
Not notifying the sale at the moment of signing the contract. The notification must be made immediately after closing the deal, not days later. Every day of delay is a day of exposure to incidents arriving in the seller's name.
Using the same digital certificate to process on behalf of several clients without a power of attorney. To manage the process on behalf of the buyer, the dealership needs a power of attorney or the buyer's express signature on the application. Without that backing, the process can be challenged.
Not following up on the status of the procedure. A transfer initiated is not a transfer completed. Verifying the status of the process 3-5 days after starting it allows detecting and resolving any issues before they become deep-seated.

Frequently asked questions
Can the dealership process the change of ownership without going to the Traffic Office?
Yes. Both via the DGT portal with a digital certificate and through an agency or platform with API integration, the procedure can be completed entirely online without needing to visit any Traffic office in person.
What happens if the buyer does not change ownership within 30 days?
The buyer breaches their legal obligation and can face penalties. If the dealership has notified the DGT of the sale at the time the contract was signed, they remain protected against incidents caused by the buyer. Without that notification, the dealership remains register-responsible.
How long does it take to complete an online change of ownership?
Under normal conditions, with all documentation in order and without complications, between 3 and 7 business days. If there are pending charges, the ITP is unpaid, or any document is missing, the period is extended until the issue is resolved.
Is the DGT fee of 55.70 euros paid by the buyer or the seller?
Usually it is paid by the buyer, as they are the one conducting the change of ownership process. If the dealership manages the procedure as a service, they can include it in the price of management or pass it on to the customer.
Is a digital certificate required to do the online procedure?
To access the DGT portal directly, yes: a digital certificate or Cl@ve access is required. If the process is managed through an integrated gestoría or platform, it is not necessary for the dealership to have its own digital certificate.
