Buying or selling a second-hand car is a significant transaction that involves more than just a handshake and an exchange of keys. In Spain, and specifically in the province of Málaga, the legal framework surrounding the transfer of vehicles requires precision and attention to detail. A poorly drafted vehicle sales contract can lead to unexpected fines, legal disputes, and financial losses. At Gestoría Bustillo SL, we have seen numerous clients face complications that could have been easily avoided with the right documentation.


1. Failing to Verify the Identity of Both Parties

One of the most frequent mistakes in a vehicle sales contract is not properly identifying the buyer and the seller. It is not enough to simply write down a name. You must include the full name, National Identity Document (DNI/NIE) number, and current fiscal address of both parties. If the seller is not the person listed on the vehicle's registration document (Permiso de Circulación), the transaction could be considered invalid or even fraudulent.

Always request a physical copy of the ID and ensure it is valid. If you are dealing with a company, you must verify the powers of the person signing on behalf of the entity. Mistakes in this area are the primary reason why the DGT (Dirección General de Tráfico) might reject a vehicle transfer application.


2. Omitting the Exact Date and Time of Delivery

Most people remember to put the date on a contract, but many forget the specific time. Why is the hour so important? In the eyes of the law, the responsibility for the vehicle shifts at the exact moment of delivery. If the buyer is caught speeding or is involved in an accident two hours after the sale, but the contract only states the date, the seller might still be held liable for the infraction.

Including the exact time (e.g., 14:30 hours) protects the seller from fines and legal issues occurring immediately after the keys are handed over. Conversely, it protects the buyer from any issues the vehicle might have had earlier that same morning.


3. Not Checking for Liens, Debts, or Encumbrances

This is perhaps the most dangerous mistake a buyer can make. In Spain, debts follow the vehicle, not the owner. If you purchase a car that has an outstanding seizure order (embargo), unpaid road taxes (IVTM), or a reservation of title (reserva de dominio) from a financing company, you will not be able to complete the transfer at the traffic office.

Before signing any vehicle sales contract, it is essential to request a "Reporte del Vehículo" (Vehicle Report) from the DGT. This document confirms the legal status of the car and ensures there are no hidden legal traps. You can find more information about these procedures on the official DGT website. At Gestoría Bustillo SL, we always recommend our clients obtain this report before any money changes hands.


4. Neglecting the Detailed State of the Vehicle

A common mistake is using a generic contract template that does not describe the actual condition of the car. To avoid future claims regarding "hidden defects" (vicios ocultos), the contract should clearly state the mileage, any known mechanical issues, and the aesthetic condition of the bodywork and interior.

If the car is being sold "as is" and the price reflects certain known faults, these must be explicitly mentioned. For private sales, the seller is liable for hidden defects for a period of six months under the Spanish Civil Code. By being transparent and documenting the vehicle's state in the contract, both parties are protected against unfair claims later on.


5. Miscalculating Tax Obligations

When a vehicle is sold between private individuals, the buyer must pay the Property Transfer Tax (Impuesto de Transmisiones Patrimoniales or ITP). In Andalusia, this tax is generally calculated based on the official tables published by the government or the sale price, whichever is higher. Failing to declare the correct amount or missing the 30-day deadline to pay the tax can result in heavy surcharges and interest from the regional tax office (Junta de Andalucía).

Many sellers and buyers also forget about the "Impuesto de Vehículos de Tracción Mecánica" (IVTM), commonly known as the road tax. By law, the person who owns the vehicle on January 1st is responsible for paying the tax for the entire year, regardless of when the car is sold. Clarifying who will cover this cost in the contract prevents heated arguments later.


6. Forgetting the Notification of Sale

The seller’s responsibility doesn’t end with the signature. A common error is assuming the buyer will complete the transfer at the DGT. If the buyer fails to do so, the seller remains the legal owner in the eyes of the administration, leading to unpaid taxes and fines. The seller should always file a "Notificación de Venta" (Sale Notification) with the DGT within 10 days of the transaction. This officially informs the authorities that the car is no longer their responsibility.
