Burden of Proof in CIS Disputes

Burden of proof in CIS disputes: what you need to know

The burden of proof in CIS disputes is an essential part of the legal process surrounding disputes arising from negative registrations in the Central Information System (CIS). In this blog article, we discuss in detail the rules and practical aspects of the burden of proof in CIS disputes, so that you better understand your rights and obligations when dealing with a CIS registration. Whether it involves proving the inaccuracy of a registration or contesting the lawfulness of a report, understanding the burden of proof can be crucial for successfully resolving your dispute.

What is the CIS and what does a CIS dispute entail?

The Central Information System (CIS) is a reporting center where insurers collect and exchange data on damage claims and fraudulent activities. The system is intended to combat insurance fraud and to better assess risks. However, because sensitive data is shared and registered, disputes can arise regarding the accuracy and lawfulness of these registrations. A CIS dispute can arise, for example, if you believe that a registration is incorrect, incomplete, or legally unjustified. In such cases, it is important to know who must provide which evidence to resolve the dispute.

The legal context of the CIS is also complex. Registrations can have far-reaching consequences, such as the refusal of insurance or higher premiums. Therefore, in a CIS dispute, it is crucial to understand which party must demonstrate that the registration is justified, and which evidence is sufficient for that purpose. More background information about the system itself can be found on our page about CIS registration: what is it and how do you remove it?.

The legal basis of the burden of proof in CIS disputes

The burden of proof in CIS disputes is not explicitly regulated in one specific law, but stems from general principles of Dutch civil procedural law and from the specific rules that apply to personal data and insurance registrations. For example, the General Data Protection Regulation (GDPR) stipulates that personal data must be correct, accurate, and up to date. In addition, the Personal Data Protection Act (Wbp) plays a role, although it has now been replaced by the GDPR.

In practice, this means that the party applying a CIS registration – usually the insurer – must be able to demonstrate that the report is justified and substantiated. This falls under the so-called burden of proof, which means that this party must provide evidence to support its claim. The insured who challenges a dispute generally does not have to prove themselves that the registration is incorrect, but can suffice with putting forward arguments and evidence that cast doubt on the accuracy of the registration.

Anyone who contests a CIS registration is well advised to set out the concrete facts and documents in the file. First request access to the registration and note which data you believe is factually incorrect. For questions about the reason or details of a registration, Stichting CIS refers to the insurer that placed the registration.

The role of evidence in CIS disputes

Evidence plays a central role in substantiating your position in a CIS dispute. This can include documents, such as claim forms, correspondence with the insurer, or witness statements. Digital data, such as camera footage or GPS tracking, can also play a role. In the context of CIS disputes, it is important that the evidence is reliable, relevant, and convincing.

A practical example: suppose you dispute that you were involved in a damage incident, while the insurer has made a registration. You can then, for example, submit camera footage showing that you were elsewhere at the time of the damage, or witness statements that support your story. Against this evidence, the insurer will have to demonstrate that the registration is nevertheless justified, for example through a loss adjuster’s report or a police report.

It is important to know that merely disputing a registration without supporting evidence is usually insufficient; you must come up with concrete evidence to have the registration removed. This is in line with the general civil procedure in which the law of evidence determines that factual assertions must be substantiated. However, the balance of the burden of proof lies with the party making a claim, so often with the insurer.

Burden of proof when contesting an unjustified CIS registration

If you believe that a CIS registration is unjustified, the task rests on you to make this plausible. This does not mean that you have to provide full proof that the registration is wrong, but you must put forward sufficient facts and circumstances that cast doubt on the accuracy of the registration. Subsequently, the insurer must prove that the registration is justified.

A practical example is a situation in which you have submitted a claim for damages, but the insurer states that there is fraud and registers this in the CIS. You can then, for example, demonstrate that the claim form was completed correctly and that there is no question of intent or untruths. This can be done by means of, for example, invoices for repairs, witness statements, or other documents that support your story. Subsequently, the insurer will have to demonstrate that there is indeed fraud, for example with an expert report.

In some cases, it may be necessary to start proceedings in court to have the registration annulled. The court will then assess whether the burden of proof has been sufficiently provided by the insurer and whether your counter-evidence is sufficient to declare the registration unjustified. More information about the difference with other registrations can be found in our article on EVR registration: difference with CIS explained.

The impact of burden of proof on the outcome of CIS disputes

The burden of proof is often decisive in the outcome of CIS disputes. Because the CIS is a system that shares negative information that can have major consequences, such as refusal of new insurance policies or higher premiums, it is of great importance that only justified registrations are included. If the insurer fails to provide sufficient evidence, the registration can be annulled.

A well-known example is the ruling of the Kifid (Financial Services Complaints Tribunal), in which an insured successfully challenged an unjustified CIS registration because the insurer could not provide conclusive evidence of fraud. The Kifid ruled that the burden of proof lay with the insurer and that the lack of concrete evidence led to the removal of the registration (Kifid.nl).

The importance of a good burden of proof is also visible in the fact that insurers increasingly use experts and data analysis to substantiate their positions. For you as an insured, it is therefore essential to obtain timely and good legal advice to strengthen your position.

Practical tips for collecting evidence for CIS disputes

When you have a CIS dispute, it is wise to start collecting relevant evidence immediately. This can make the difference in successfully contesting a registration. Below are some practical tips:

  • Keep all correspondence with the insurer, including emails, letters, and notes of telephone conversations.
  • Collect original documents such as claim forms, invoices, repair reports, and witness statements.
  • Where possible, ask for evidence from the insurer, for example the expert report or camera footage.
  • Document the situation as fully as possible, for example by taking photos of damage and circumstances.
  • Take deadlines into account: a CIS registration can only be contested within a certain time.

It is also advisable to contact a specialized lawyer at an early stage, such as Arslan & Arslan Advocaten, who has experience with CIS disputes and can guide you in collecting and assessing evidence. More about the incident register can be found on our page Incident register: how do you get in and what can you do?.

The role of the judge and dispute bodies in burden of proof in CIS cases

When a CIS dispute cannot be resolved out of court, the dispute can be submitted to the court or the Kifid. When assessing the case, the judge or the Kifid will make a careful assessment of the burden of proof. The party making a claim must prove it. In CIS cases, this means that the insurer must demonstrate that the registration is justified and that there is a valid reason for registration.

The judge will pay attention to the quality of the evidence and the arguments of both parties. If the insured makes it plausible that the registration is incorrect, the judge can reverse the burden of proof and oblige the insurer to provide the evidence. In case of ambiguities or insufficient evidence, the registration can be annulled.

The Kifid has also emphasized the importance of a correct burden of proof in several rulings and acts as an accessible body for resolving CIS disputes. For extensive case law on this subject, you can visit rechtspraak.nl.

Burden of proof in CIS and the importance of legal assistance

Dealing with burden of proof in CIS disputes requires legal expertise. The rules can be complex and the importance of a correct registration is great. Legal assistance can help you to collect, assess, and present the evidence in the right way. Moreover, a lawyer can conduct negotiations with the insurer on your behalf or start proceedings before the court or the Kifid.

Frequently asked questions

What exactly does burden of proof mean in a CIS dispute?

Burden of proof means that the party making a claim must also provide the evidence supporting that claim. In CIS disputes, this usually means that the insurer must demonstrate that a registration is justified, for example because there was insurance fraud or incorrect data. The insured must indicate why he or she believes the registration is incorrect, but does not have to fully prove that the registration is wrong.

Can I have a CIS registration removed if I have evidence that it is incorrect?

Yes, if you can provide evidence that a CIS registration is incorrect or unlawful, you can request the removal of the registration. This can be done via the insurer itself, but it is often necessary to take legal steps, for example by filing a complaint with the Kifid or starting proceedings in court. The stronger your evidence, the greater the chance of removal.

What are the consequences if the insurer has insufficient evidence for a CIS registration?

If the insurer cannot provide sufficient evidence for a CIS registration, this can lead to the registration being annulled or removed. This prevents you from being unfairly disadvantaged in future insurance applications or premium calculations. In addition, the insurer can be held liable for any damage resulting from an unjustified registration.
