In personal injury cases, the discussion often revolves around one central question: which damage is the result of the accident? In this discussion, the concepts of predisposition and pre-existence frequently arise. Insurers like to invoke these concepts to limit compensation. However, the existence of prior complaints does not automatically mean that you are entitled to less compensation.
In this article, we therefore explain in detail what predisposition and pre-existence mean in personal injury cases, how judges deal with these concepts, and what this concretely means for your damage claim. Additionally, you will learn how to prevent your complaints from being unjustly dismissed as 'pre-existing'.
What is meant by pre-existence in personal injury cases?
Pre-existence refers to a situation where you already had complaints, conditions, or limitations before the accident. Examples include:
- existing back or neck complaints;
- a previous herniated disc or whiplash;
- psychological complaints such as anxiety or depression;
- osteoarthritis or other chronic conditions.
When you experience renewed or worsened complaints after an accident, the insurer often claims that these complaints (partly) already existed. This leads to a dispute about the causal connection.
What is predisposition?
Predisposition means that before the accident you had a susceptibility to certain complaints, but that these complaints had not yet (or barely) manifested themselves.
Examples of predisposition include:
- wear and tear that had not yet caused complaints;
- a vulnerable psychological condition without treatment;
- an anatomical abnormality without functional limitations.
In these situations, the accident acts as a 'trigger', causing complaints to arise or seriously worsen.
The difference between predisposition and pre-existence
Although the terms are often used interchangeably, there is an important difference:
- Pre-existence: complaints already existed before the accident.
- Predisposition: there was only an increased vulnerability, without complaints.
This distinction is crucial for the assessment of liability and compensation.
Does the liable party continue to pay in cases of pre-existence?
A common misconception is that no right to compensation exists in cases of pre-existence. This is incorrect. Even when you already had complaints, the liable party may remain obligated to compensate the damage.
The key question is: would you have ended up in the same situation without the accident?
If the accident led to a worsening of complaints, additional limitations, or accelerated loss of function, then that damage is in principle eligible for compensation.
Predisposition and the 'thin skull' principle
In liability law, the principle applies that a tortfeasor must take the victim as they find them. This is also known as the thin skull principle.
This means that an increased vulnerability or susceptibility to complaints may not be at the expense of the victim. In other words: if you had a predisposition, the liable party remains responsible for the consequences that the accident caused in your case.
How do insurers deal with predisposition and pre-existence?
In practice, insurers often try to limit damage claims by asserting that complaints (largely) already existed. In doing so, we regularly observe that:
- medical history is used selectively;
- old complaints are equated with new limitations;
- recovery is attributed to 'natural progression'.
This is precisely why careful medical and legal substantiation is essential.
The causal connection in personal injury cases
In cases involving predisposition and pre-existence, the causal connection is central. The question is to what extent the accident contributed to your current complaints and limitations.
The following factors are considered:
- your complaints before the accident;
- your functioning before the accident;
- the development of complaints after the accident;
- medical reports and expert assessments.

Medical expert assessments and predisposition
In many personal injury cases, a medical expert assessment is carried out. The expert then evaluates, among other things:
- whether pre-existing complaints were present;
- whether a predisposition existed;
- to what extent the accident caused or worsened the complaints;
- how the pattern of complaints would have developed without the accident.
This assessment is often decisive for the final compensation.
Damage calculation in cases of predisposition and pre-existence
When it is established that both the accident and prior factors play a role, a damage apportionment may apply. However, this does not automatically mean that you will only receive compensation for a small portion.
It is important to note that only the portion of the damage that would also have occurred without the accident is excluded. The remainder remains at the expense of the liable party.
More information about this can also be found on our page about compensation for personal injury.
Psychological complaints and pre-existence
Pre-existence is also regularly invoked in cases involving psychological complaints. Insurers then claim that complaints such as stress, anxiety, or depression already existed.
Here too, the following applies: if you led a normally functioning life before the accident and the limitations only arose afterwards, the accident remains legally relevant.
Frequently asked questions
Will I receive less compensation if I already had complaints?
No, not automatically. Only damage that would also have occurred without the accident can be excluded.
May an insurer use old medical records?
Yes, but only insofar as they are relevant. Selective use of medical information is not permitted.
What if my complaints only worsened later?
Later worsening can also be eligible for compensation, provided the connection with the accident is plausible.
What can you do yourself?
When predisposition or pre-existence is raised, it is important that you:
- share your medical history completely and honestly;
- properly document your functioning before the accident;
- seek legal guidance;
- do not agree too quickly with a position taken by the insurer.
Does legal assistance cost me money?
In personal injury cases, the costs of legal assistance are in most cases recovered from the liable party or their insurer. As a result, you as the victim bear no net financial risk.
