Five Types of Evidence to Strengthen Your Personal Injury Lawsuit 

When filing a personal injury lawsuit, you must meet a certain threshold to win your case and be eligible for compensation. This limit is known as the preponderance of evidence, and it alludes to demonstrating the defendant was more likely to have caused you harm. For that, you’ll need proof.

“Evidence is the backbone of any personal injury lawsuit; it can be the difference between winning or losing your claim,” says personal injury attorney Kyle Valero of Valero Law Group Injury Lawyers. This blog will highlight the five essential types of documentation you should use to strengthen your suit. Keep reading below for more details.

The Role of Evidence in Personal Injury Cases

In California, the injured party must demonstrate that the defendant caused them harm to:

  • Establishing liability: It demonstrates that the defendant’s actions or lack of actions led to your injury.
  • Proving the extent of injuries and damages: Evidence like medical reports substantiates the afflictions you sustained and to what degree. 
  • Supporting claims: Evidence like witness testimony can be used to back up your claim for monetary and nonmonetary compensation.

Types of Key Evidence

Below are the five key types of proof you should use:

Photographic and Video Evidence

This refers to the visual records that depict details about the accident scene, the injuries you sustained, and the surrounding conditions. Such documentation is highly effective in backing up your claim because it provides a clear, objective view of what occurred.

You can take pictures and videos immediately after the accident, get the footage from security or surveillance cameras, and, if available, use dashboard or body cameras.

Medical Records and Reports

Medical documentation sheds light on the nature, extent, and progress of the injuries that you sustained. Such proof is often foundational in most personal injury claims because it establishes a direct link between the incident and your damages.

These records include documents from your doctor that detail your diagnosis, treatment, and medical evaluations. You should also make use of reports prepared by medical professionals. They may detail your treatment regimen and even the expected impact on your life. 

Witness Statements

You also need first-hand accounts of people who observed the accident or events that are related to your injury. These accounts provide objective perspectives that can support your claims and add credibility to your lawsuit.

A witness statement can be written or sworn testimony. And because most witnesses have no vested interests in the outcome of the case, their statements appear more impartial.

Police Reports

A police report is an official document that is created by the cop who responds to your accident or incident. It contains their observations, statements from the parties involved, and sometimes, a preliminary assessment of who might have caused the incident.

You can request a report from your local police department within days of the accident. This crucial piece of evidence offers a credible, third-party account of the incident, laying a strong foundation for establishing liability.

Expert Testimonies

An expert witness is a professional with expertise and specialization in a certain field. It may be a doctor, a police officer, a surgeon, or even an accident reconstruction expert. Your personal injury attorney can help you hire a credible expert witness to strengthen your claim. 

An expert witness does not have to have witnessed the accident per se. Their testimony comes from their expertise in a specific field, which puts them in a better position to clarify important matters for the court. For instance, a doctor can explain how your injuries will affect your future going forward.
