Buying a used car does not mean that the existing liability insurance expires the moment the contract is signed. If the vehicle has valid mandatory insurance, the following are transferred to the buyer: rights and obligations under this agreement. The new owner may continue to be covered until the end of the period specified in the policy or may cancel the transferred policy. However, the owner must keep in mind that such a policy will not automatically renew for another year. In practice, three things are most important: confirming the validity of the liability insurance, finding out the expiration date of the coverage, and checking whether the insurer will recalculate the premium after the change of ownership.
Does liability insurance transfer to the buyer?
Yes—if the car is covered by a valid compulsory liability insurance policy, a change in ownership results in the transfer of the rights and obligations under this contract to the purchaser. The Polish Financial Supervision Authority notes that this rule applies to cases of transfer or assignment of ownership of the insured vehicle, regardless of who originally entered into the contract.
Therefore, one should not assume that coverage automatically ends when the car is sold. However, the buyer should determine the exact date when coverage ends, rather than relying solely on the seller’s assurance. The date on the policy sets a practical deadline by which you must decide whether to keep the transferred policy in effect until it expires or to cancel it and arrange for different coverage for the vehicle.
The most important caveat is: assumed liability insurance It does not renew automatically for the next 12-month period. The absence of a notice of termination does not, therefore, mean that another contract will take effect after the expiration date. This is a common risk when buying a car—the driver may continue to use the transferred policy for several weeks and then overlook its expiration.
Important: This answer pertains to mandatory liability insurance for motor vehicle owners.
These rules should not be applied to auto insurance, roadside assistance, or other voluntary insurance policies without first reviewing the terms of the specific policy.
What exactly is the new owner taking over?
The buyer assumes not only the right to coverage but also the obligations arising from the existing contract. Therefore, it is important to read the insurance policy carefully, check the coverage period, and contact the insurer to update your information.
The new owner has two main options:
- keep the transferred liability insurance and use it until the end of the coverage period;
- terminate the existing policy and purchase a new one, ensuring uninterrupted coverage for the vehicle.
If the buyer keeps the policy, The insurer may recalculate the premium from the date of the change in ownership. The calculation takes into account the new owner’s information under the applicable rate plan. This means that the financial terms established for the seller do not necessarily remain the same after the car is purchased.
Marta buys a car with liability insurance that is still valid for a few more months. She can use this policy until the end of the specified period. However, the insurer may recalculate the premium after the change of ownership, and the policy itself will not renew automatically. Marta notes the expiration date and decides in advance how to continue her coverage.
If the buyer is considering termination, It should not result in a gap in liability insurance coverage. The policyholder has the right to terminate the assumed policy, but before submitting the document, he or she should agree with the insurer on the effective date of termination and the procedure for doing so. This allows the policyholder to properly plan for the next policy and keep the relevant documentation.
What Should You Do After Buying a Car?
A good sequence of steps reduces the risk of misunderstandings. Start by verify the liability insurance document received from the seller. Check the vehicle information, the insurer’s name, and the policy term. Then contact the insurer and notify them of the change in ownership according to their procedure.
A helpful checklist for buyers:
You can read more about the product itself on the page describing it Scope of auto liability insurance coverage. If you're putting together the documents for a transaction, a guide on what You need these documents when buying a car with liability insurance.
Service procedures do not have to be exactly the same at every insurance company, which is why what matters is the terms and conditions of a specific insurer. An Allianz document from 2025 indicates that the purchaser of a car insured with Allianz may continue to use the transferred policy until the end of the term or cancel it. If the policy is continued, Allianz also describes the documents needed to update it.
In practice, it’s not a good idea to put off contacting your insurer. Clarifying the status of your policy early on allows you to determine whether your information has been updated, whether additional documents are needed, and whether your premium will be recalculated.
What are the seller's responsibilities?
Above all, the seller should provide the buyer with proof of liability insurance. This allows the buyer to identify the policy, verify the coverage period, and contact the appropriate insurer. A verbal assurance alone that „the policy is valid” is no substitute for the document.
A document from TUZ Ubezpieczenia dated July 15, 2026, states that when a vehicle is sold, TUZ Ubezpieczenia must be notified in writing of the transfer of ownership and the new owner’s information. The document specifies notification within 14 days and providing the new owner with a document confirming the purchase of liability insurance.
These obligations are outlined in the insurance policy terms and conditions. If you are selling a car insured with another company, check the applicable deadlines, required information, and the procedure for reporting the sale. Do not assume that simply signing the sales contract constitutes notification to the insurer.
Piotr is selling a car covered by liability insurance through TUZ Ubezpieczenia. He provides the buyer with the insurance policy document and then follows TUZ’s procedure: he submits written notification of the change in ownership and the new owner’s information within the timeframe specified in the document. He does not assume that the signed sales contract automatically updates the insurer’s records.
Practical rule: Both parties should keep a copy of the sales document, the insurance policy, and any correspondence with the insurer.
This makes it easier to determine the dates and scope of the information provided.
Premium Recalculation and End of Coverage
After the change in ownership Recalculation does not occur automatically in every case. If the purchaser does not terminate the transferred contract, the insurer may recalculate the premium due as of the date of transfer of ownership. In doing so, the insurer takes into account the discounts and surcharges applicable to the new owner in accordance with the current rate schedule.
At the same time The buyer's request triggers the obligation to recalculate for the period beginning on the date of the change in ownership. This distinction is important: the insurer has the option to recalculate the premium on its own initiative, and must perform such a calculation at the request of the new owner.
An Allianz document regarding the continuation of liability insurance after purchasing a vehicle states that a copy of the vehicle registration certificate after the number has been changed and an application containing the new owner’s information and a request for an updated policy document. However, this is not a one-size-fits-all set of documents for the entire market. This illustrates why the buyer should verify the procedure specific to their contract.
The most important date is still listed on the acquired policy. The contract remains in effect until the end of the term for which it was entered into, unless the purchaser terminates it earlier. Upon the expiration of that term no automatic renewal means that another contract must be secured separately.
It is good organizational practice to mark the deadline on your calendar and begin preparations well in advance. Although this does not change the legal rules, it helps prevent you from missing an important date. Whenever you change your decision—whether to keep the policy, file a request for a premium recalculation, or cancel the policy—it’s a good idea to obtain clear confirmation from the insurer.
