When you’re injured in an accident in New York, proving that your injuries were directly caused by the incident is crucial to your personal injury claim. This legal concept, known as “causal relationship” or causation, can make or break your case. Understanding how New York courts evaluate causation can help you build a stronger claim and get the compensation you deserve.
What is Causal Relationship in Personal Injury Law?
Causal relationship, also known as causation, is the legal link between a defendant’s actions (or inaction) and the plaintiff’s injuries. In New York personal injury cases, you must prove that the defendant’s negligence was both the actual cause and the legal cause of your harm.
This requirement stems from the fundamental principle that defendants should only be held liable for injuries they actually caused. Without establishing causation, even the most egregious negligence won’t result in compensation for your injuries.
The Two Types of Causation in New York
New York law recognizes two distinct types of causation that must both be proven:
1. Factual Causation (Cause-in-Fact)
This is the “but for” test: would your injury have occurred “but for” the defendant’s negligent conduct? If the answer is no, factual causation is established.
2. Legal Causation (Proximate Cause)
This determines whether the defendant should be legally responsible for your injuries, even if they factually caused them. The injury must be a foreseeable consequence of the defendant’s actions.
Common Causation Challenges in New York Personal Injury Cases
Pre-Existing Conditions and Degenerative Injuries
One of the most common challenges in establishing causation involves pre-existing medical conditions. As demonstrated in Mnatcakanova v Elliott, 2019 NY Slip Op 05772 (2d Dept. 2019), defendants often argue that a plaintiff’s injuries are degenerative rather than trauma-related.
In this case, the court noted: “Although the plaintiff submitted, inter alia, an affirmed medical report in which her expert opined that her injuries were causally connected to the accident, the evidence submitted by the plaintiff failed to address the findings of the moving defendants’ expert that the injuries to her spine and knee were degenerative in nature.”
Multiple Potential Causes
When several factors could have caused your injury, proving causation becomes more complex. New York courts may apply the “substantial contributing factor” test, where you must show the defendant’s conduct was a substantial factor in causing your harm.
Time Gaps Between Accident and Injury
The longer the time between an accident and when symptoms appear, the harder it becomes to establish causation. Insurance companies and defense attorneys will scrutinize any delay in seeking medical treatment or reporting symptoms.
How to Strengthen Causation in Your Personal Injury Case
Immediate Medical Attention
Seek medical care immediately after an accident, even if you feel fine. This creates a clear timeline connecting the incident to your injuries and prevents insurance companies from arguing that something else caused your condition.
Comprehensive Medical Documentation
Work with healthcare providers who understand personal injury cases. They should:
- Document the mechanism of injury
- Explain how the accident could cause your specific injuries
- Address any pre-existing conditions and how the accident aggravated them
- Provide detailed treatment records showing the progression of your condition
Expert Medical Testimony
In complex cases, expert medical testimony may be necessary to establish causation. These experts can:
- Review medical records and imaging studies
- Explain the biomechanics of your injury
- Differentiate between trauma-related and degenerative conditions
- Counter defense expert opinions
Legal Standards for Proving Causation in New York
The Role of Medical Expert Opinions
New York courts generally require medical expert testimony to establish causation when the connection isn’t obvious to laypeople. The expert must:
- Be qualified in the relevant medical field
- Base opinions on accepted medical principles
- Explain their reasoning in understandable terms
- Address contrary evidence presented by the defense
Burden of Proof Standards
In personal injury cases, you must prove causation by a “preponderance of the evidence” – meaning it’s more likely than not that the defendant caused your injuries. This is a lower standard than the “beyond a reasonable doubt” requirement in criminal cases.
Summary Judgment Considerations
Defendants often file summary judgment motions arguing that causation cannot be established. To survive these motions, your medical evidence must be sufficient to create a genuine issue of material fact regarding causation.
Causation in Different Types of Personal Injury Cases
Car Accident Cases
In vehicle collisions, causation is often straightforward – the impact directly causes injuries. However, challenges arise with:
- Low-impact accidents
- Delayed onset of symptoms
- Pre-existing spinal conditions
- Multiple vehicle collisions
Slip and Fall Cases
Premises liability cases require proving that the dangerous condition caused your fall and resulting injuries. Common issues include:
- Alternative causes for the fall
- Pre-existing balance or mobility problems
- Footwear or other contributing factors
Medical Malpractice Cases
These cases involve complex causation questions:
- Would the injury have occurred with proper care?
- Did the malpractice accelerate an existing condition?
- How do you separate natural disease progression from treatment-related harm?
Recent New York Case Law on Causation
Recent decisions show New York courts taking a careful approach to causation:
- Courts scrutinize medical expert opinions for adequate foundation
- Mere temporal relationship between accident and injury isn’t sufficient
- Defense experts successfully challenge causation when plaintiff experts don’t address degenerative findings
- Summary judgment is granted when causation evidence is insufficient

Frequently Asked Questions About Causal Relationship
Q: Can I recover damages if I had a pre-existing condition?
A: Yes, you can still recover damages even with a pre-existing condition. New York follows the “eggshell plaintiff” rule, meaning defendants take plaintiffs as they find them. If the accident aggravated or accelerated your pre-existing condition, you may be entitled to compensation for the worsening of your condition.
Q: How long do I have to establish the causal relationship between my accident and injuries?
A: While there’s no specific deadline for proving causation, seeking immediate medical attention is crucial. The longer you wait to see a doctor or report symptoms, the harder it becomes to establish that the accident caused your injuries rather than some intervening event.
Q: What if my doctor isn’t sure whether my injuries are related to the accident?
A: Medical uncertainty doesn’t automatically defeat your case, but it makes proving causation more challenging. Consider getting a second medical opinion or consulting with a specialist who has experience in personal injury cases. Sometimes additional testing or consultation with experts can clarify the causal relationship.
Q: Can the defense use my social media posts to challenge causation?
A: Yes, insurance companies and defense attorneys regularly review social media accounts for evidence that might undermine causation claims. Be careful about posting photos or comments that could suggest your injuries aren’t as severe as claimed or that other activities might have caused your condition.
Q: What happens if there were multiple causes of my injury?
A: New York law allows recovery when the defendant’s negligence was a “substantial contributing factor” to your injuries, even if other factors also played a role. However, your damages may be reduced based on the degree to which other factors contributed to your harm.
