When you’ve been injured in an accident due to someone else’s negligence, winning your personal injury case in New York depends on the strength of your evidence. Whether it’s a car crash, slip and fall, or construction site accident, you must be able to prove that another party caused your injuries and that you suffered damages as a result.



At the Law Offices of John E. Gray, we help injury victims throughout New York build strong cases and fight for the compensation they deserve. Here's a breakdown of the critical evidence you’ll need to support your personal injury claim.

1. Accident Reports

An official accident report provides a foundational piece of evidence. This can include:

• Police reports for car accidents
• Incident reports for slip and fall injuries in stores or public places
• OSHA reports for workplace injuries

These documents help establish the time, place, and immediate circumstances of the incident, often including initial statements and eyewitness information.

2. Medical Records and Bills

You’ll need comprehensive medical documentation to show:

• The extent of your injuries
• Treatment received
• Medical expenses incurred
• Prognosis and long-term impacts

Medical records serve as proof that the injuries were real, significant, and directly tied to the accident.

3. Photographs and Videos

Visual evidence is powerful. Photos or videos taken at the scene of the accident can demonstrate:

• Hazardous conditions (such as wet floors or broken stairs)
• Vehicle damage or location of impact
• Injuries sustained immediately after the event

Surveillance footage from nearby businesses or dashcams can also support your version of events.

4. Witness Statements

Neutral third-party witnesses can help corroborate your story. Their testimony can provide:

• An unbiased account of how the accident occurred
• Additional insight into the behavior of the negligent party

It’s important to get contact information from any witnesses as soon as possible after the accident.

5. Proof of Lost Wages

If your injuries forced you to miss work, you can claim lost income. Useful documents include:

• Pay stubs or tax returns
• Letters from your employer
• Timesheets showing missed days

This helps quantify your financial losses beyond medical bills.

6. Expert Testimony

In some cases, expert opinions can strengthen your case. For example:

• Medical professionals explaining the long-term effects of your injuries
• Accident reconstruction experts establishing how the incident happened
• Economic experts calculating future lost earning capacity

Expert testimony is especially valuable in high-stakes or complex injury cases.

7. Pain and Suffering Documentation

Emotional and psychological impacts matter, too. You can document this with:

• Journals describing your day-to-day pain
• Therapy records
• Statements from friends or family members about changes in your behavior or lifestyle

Though harder to quantify, this type of evidence supports claims for non-economic damages.
