How to Change Vehicle Ownership in Denmark

When a vehicle changes hands in Denmark, it is legally required for the change of ownership to be registered with the Danish Motor Vehicle Agency (Motorstyrelsen) in the national vehicle register, Motorregistret. This process, known as omregistrering (re-registration), ensures that the correct person or entity is listed as the legal owner and is responsible for all associated duties, including vehicle taxes and insurance. Both the buyer and the seller have roles to play, but the primary responsibility for initiating the re-registration typically falls on the new owner. Failure to complete this process within a strict four-weekday deadline can have significant financial and legal implications for the previous owner.

Understanding Vehicle Ownership Transfer in Denmark

Transferring vehicle ownership is a critical administrative step following the sale or purchase of a car, motorcycle, caravan, or trailer in Denmark. It moves the legal and financial responsibility for the vehicle from the seller to the buyer. This procedure is handled digitally through the Motorregistret portal or the Ejerskifte app for most private vehicles, or via an authorised nummerpladeoperatør (number plate operator) for specific vehicle types or complex cases.

Scope of This Guide

This guide details the procedure for changing ownership of vehicles that require registration and number plates in Denmark, including:

• Passenger cars (personbiler)
• Motorcycles (motorcykler)
• Mopeds (knallerter)
• Caravans (campingvogne)
• Trailers (trailere)

It focuses on transfers between private individuals. Commercial vehicles, vehicles with special conditions (klausul), or certain heavy machinery may have different, more complex procedures often requiring a nummerpladeoperatør.

The Critical 4-Weekday Deadline and Its Importance

The new owner of a vehicle must re-register or deregister the vehicle within four weekdays of the purchase date. This deadline is not merely an administrative suggestion; it is a legally binding requirement designed to protect both parties, especially the seller.

Seller's Continued Liability

Until the vehicle is officially re-registered in the buyer's name (or deregistered), the seller remains the legally registered owner in Motorregistret. This means:

• Taxes: The seller is responsible for paying all periodic vehicle taxes. If the buyer delays re-registration, the seller will receive the tax bills. While Motorstyrelsen will adjust the tax amount to reflect the period of ownership once the re-registration occurs (and automatically refund any overpaid amounts to the seller's NemKonto if no public debt exists), the initial liability rests with the seller.
• Insurance: The seller is responsible for the mandatory third-party liability insurance. Without proper re-registration, the seller's insurance policy for that vehicle might still be active, leading to ongoing costs or potential issues if the new owner is involved in an accident before transferring coverage.
• Periodic Inspection (Periodisk Syn): If a periodic technical inspection is due or has been called for, the registered owner (the seller) will receive the summons from Færdselsstyrelsen. It is crucial for the seller to inform the buyer about any upcoming inspections at the time of sale.

Preparing for Vehicle Ownership Transfer

Before initiating the ownership change, both the buyer and seller should ensure they have the necessary information and access. A thorough preparation can prevent delays and complications.

Essential Checklist for Buyers and Sellers

Here's what you need to have ready for a smooth omregistrering:

• MitID: Both buyer and seller must have a valid MitID for digital authentication, as most procedures are online.
• Registreringsattest (Registration Certificate): This document contains key vehicle details. The seller should provide this to the buyer.
  • Note: If using the Ejerskifte app, the physical registration certificate is not strictly required, but knowing the vehicle's registration number or chassis number is essential.
• Sales Agreement (Slutseddel): While not always a mandatory document for the re-registration itself, a written sales agreement is highly recommended. It serves as proof of the sale, detailing:
  • Sales date
  • Seller's name and signature
  • Buyer's name, address, and signature
  • Vehicle's registration number or chassis number (stelnummer)
  • Optional: Buyer's date of birth and driving licence number. This document is crucial if there are disputes or if the seller needs to request forced deregistration.
• Valid Vehicle Insurance: The buyer must have valid third-party liability insurance for the vehicle before completing the re-registration. You will need to select an insurance company during the online process.
• Payment Method: A debit or credit card is needed to pay the re-registration fee.

Who is Responsible for What?

Aspect	Buyer's Responsibility	Seller's Responsibility

Insurance	Obtain new liability insurance coverage before re-registration.	Ensure existing insurance is cancelled after re-registration.
Documents	Have MitID, payment card, and registreringsattest (if using Motorregistret).	Have MitID, registreringsattest, and a signed slutseddel.
Monitoring Status	Confirms successful re-registration.	Monitors Motorregistret to ensure re-registration is complete.
Compliance	Meet the 4-weekday deadline.	Act if the buyer fails to meet the deadline.

How to Change Vehicle Ownership: Buyer's Guide

As the buyer, you have the primary responsibility to re-register the vehicle. You have three main options for omregistrering in Denmark.

Option 1: Re-registering in Motorregistret (Online Portal)

This is the standard digital method for most private vehicles.

Vehicles You CANNOT Re-register in Motorregistret:

Some vehicles cannot be re-registered online and require the assistance of a nummerpladeoperatør. These include:

• Trucks (lastbiler)
• Tractors (traktorer)
• Motorized implements (motorredskaber)
• Semi-trailers (sættevogne)
• Tractor trailers (traktorpåhængsvogne)
• Trailed implements (påhængsredskaber)
• Vehicles with custom number plates (ønskenummerplader)
• Vehicles without number plates (køretøjer uden nummerplade)
• Vehicles with specific legal clauses (klausul), such as crew vans or taxis.

If your vehicle falls into one of these categories, proceed to Option 3.

Option 2: Re-registering via the Ejerskifte App

The Ejerskifte app offers a streamlined process for changing ownership of privately owned vehicles (passenger cars, motorcycles, mopeds, trailers, and caravans) between two private individuals. A key advantage is that you do not need the physical registreringsattest for this method.

Option 3: Re-registering at a Number Plate Operator (In-Person)

If your vehicle type prevents online re-registration, or if you prefer in-person assistance, you must visit an authorised nummerpladeoperatør. These operators include private inspection centres (synshaller) or car dealerships.

Seller's Responsibilities and Safeguards

As a seller, your primary responsibility is to ensure the buyer re-registers the vehicle within the 4-weekday deadline. Until this happens, you are still legally and financially responsible.

What to do Immediately After Selling

1. Provide Registreringsattest: Hand over the registreringsattest (registration certificate) to the buyer.
2. Sign a Sales Agreement (Slutseddel): Always create and sign a detailed sales agreement with the buyer. This document is your proof of sale and crucial if the buyer fails to re-register. Ensure it includes:
   • Date of sale
   • Full names, addresses, and signatures of both seller and buyer
   • Vehicle's registration number and chassis number
3. Inform About Periodic Syn: If the vehicle has an upcoming periodisk syn (periodic inspection) or has already received an invitation for one, inform the buyer clearly. The inspection deadline does not change with re-registration.
4. Cancel Insurance: Contact your insurance company after the vehicle has been re-registered to cancel your policy for that specific vehicle. Do not cancel it before the re-registration is complete.

How to Check Re-registration Status (Seller)

It is crucial for sellers to verify that the re-registration has been completed.

If the Buyer Fails to Re-register: Seller's Action

If more than four weekdays have passed and the vehicle is still registered in your name, you can ask Motorstyrelsen to deregister it. This is a critical step to protect yourself from ongoing liability.

Motorstyrelsen will deregister the vehicle on the day they receive your request, but no earlier than four weekdays after the sale date documented in your slutseddel.

Costs and Payment

The fees for re-registering a vehicle in Denmark are standard, but can vary slightly depending on the method chosen.

Method	Cost (DKK)	Notes
Motorregistret (Online)	340	Most cost-effective, requires registreringsattest.
Ejerskifte App (Mobile)	340	Convenient, does not require physical registreringsattest.
Number Plate Operator (In-Person)	380 + Operator Fee	Highest cost, necessary for certain vehicles, includes operator's service charge.

Note: These fees are for the re-registration process itself and do not include vehicle taxes, insurance premiums, or any costs associated with new number plates (if applicable).

Common Mistakes and How to Avoid Them

Failing to properly transfer vehicle ownership can lead to unnecessary expenses, legal complications, and stress. Be aware of these common pitfalls:

• Missing the 4-Weekday Deadline:
  • Mistake: Buyer delays re-registration, or seller doesn't follow up.
  • Avoid: Buyer must prioritise re-registration immediately. Seller must check Motorregistret regularly and initiate forced deregistration if the deadline is missed.
• No Written Sales Agreement (Slutseddel):
  • Mistake: Relying on a verbal agreement or incomplete details.
  • Avoid: Always prepare and sign a comprehensive sales agreement detailing vehicle, buyer, seller, and sale date. This is your key proof.
• Incorrect Vehicle Type for Online Registration:
  • Mistake: Attempting to re-register a truck, taxi, or a vehicle with special plates via Motorregistret or the Ejerskifte app.
  • Avoid: Consult Motorstyrelsen guidelines for your specific vehicle type. If it's on the exclusion list, plan to visit a nummerpladeoperatør.
• Assuming Seller's Insurance Transfers:
  • Mistake: Buyer drives the vehicle believing the seller's insurance covers them, or seller cancels insurance too soon.
  • Avoid: Buyer must secure new insurance before re-registration. Seller must only cancel their policy after confirmation of the new owner's registration.
• Ignoring Digital Post:
  • Mistake: Missing official notifications from Motorstyrelsen or Færdselsstyrelsen regarding the vehicle.
  • Avoid: Regularly check your Digital Post for any correspondence related to vehicle ownership, taxes, or inspections.
• Not Checking Motorregistret After Sale (Seller):
  • Mistake: Trusting the buyer without verification.
  • Avoid: Always log into TastSelv and Motorregistret to confirm the vehicle is no longer registered in your name within a few days of sale.
• Driving on Foreign Plates as a Danish Resident:
  • Mistake: Buying a vehicle abroad and importing it without understanding Danish registration rules for residents.
  • Avoid: This guide specifically covers vehicles already registered in Denmark. Importing a vehicle has a separate, more complex procedure involving valuation and registration tax.
• Not Informing Buyer About Periodisk Syn:
  • Mistake: Seller forgets to mention an upcoming or due periodic inspection.
  • Avoid: Always check the syn status of the vehicle and inform the buyer. The new owner will inherit this responsibility.

What Happens Next?

Once the omregistrering is successfully completed:

• Buyer: The vehicle is officially registered in your name. You are now responsible for all vehicle taxes, insurance, and future maintenance/inspections. You will receive digital confirmation in your Digital Post.
• Seller: The vehicle is removed from your list of active vehicles in Motorregistret. Your liability for taxes and insurance ceases from the date of re-registration. Any overpaid periodic vehicle taxes will be automatically refunded to your NemKonto. Your insurance company will be notified of the ownership change, and you can proceed with cancelling your policy for the vehicle.
