A personal injury case may be your most viable option for recovering your losses after another party has injured you, but proving fault can be a challenge in some cases. It’s vital to understand the role of expert witnesses in personal injury cases in California and find an attorney who can build the strongest possible case for you.
Success with any personal injury case in California requires identifying the party you believe to be responsible for causing damages, proving exactly how they caused your personal injury, and then showing the full scope of the resulting damages. The plaintiff in a personal injury case has the right to claim compensation for the economic and non-economic losses they suffered because of a defendant’s negligence or illegal misconduct.
This may sound straightforward, but the reality is that even if you think you know exactly how your injury happened and who is responsible, the actual legal process of ensuring their accountability will be more challenging than you expect.
For example, motor vehicle crashes are a leading cause of personal injuries in the United States each year. The National Safety Council reported that in 2023, vehicle accidents caused more than 5.1 million injuries and nearly $514 billion in economic damages nationwide. In California, all vehicle accidents involving multiple drivers are resolved based on fault. This means you will need to prove fault for your accident before you can claim compensation for your damages.
Physical and digital evidence could be crucial to any personal injury case, but expert witness testimony is often required for more complex cases. It’s possible for several types of expert witnesses to provide valuable professional insights that can help a plaintiff win their case:
These are just a few examples of how expert witness testimony can be valuable to a personal injury case in California. The average person may not know how to connect with relevant experts and how to secure their testimony to support their cases, so it’s vital to hire a personal injury lawyer right away after your injury, so they can help you build your case.

The difference between eyewitness testimony and expert witness testimony is that an eyewitness is someone who saw an incident occur. They relay their recollection of the event and may be able to help a plaintiff’s case. An expert witness is someone called to testify in support of a case due to their specific professional background. They did not physically witness the event, but they are capable of analyzing the details to provide insights.
No, expert witness testimony is not necessary for every personal injury case. However, expert witness testimony is likely to come into play when a case involves complex technical details. When you hire a personal injury lawyer to represent you, they can determine whether expert witness testimony of any kind could be valuable to your case, and an experienced attorney will know how to obtain this testimony for you.
The standard for expert witnesses in California is that an expert witness must prove that they possess specific credentials and professional experience in a field that is relevant to the case and that they can provide specific insights into complex aspects of the case that may otherwise go unaddressed. They must also be able to explain the methods used to develop the professional insights they contribute to the case.
It is possible to win more compensation with expert witness testimony than you could win otherwise. For example, an expert witness may be able to prove that your claimed damages, including projected future losses, directly resulted from the defendant’s actions. Without their testimony, the defendant could successfully argue against their liability for these losses, diminishing the plaintiff’s recovery.
Ultimately, many personal injury cases are more complex than they appear at first. While it’s crucial to hire a personal injury lawyer at your first opportunity after another party has injured you in California, it is important to verify that your chosen attorney has the professional resources necessary to provide the highest possible level of legal counsel for your case.
