Personal Injury Attorneys
California Catastrophic & Brain Injury Lawyers
A catastrophic injury changes everything, often in a single moment. Traumatic brain injuries, spinal cord damage, paralysis, severe burns, and amputations can require a lifetime of care and reshape a family's entire future. These cases demand more than a quick settlement. At Mousavi Law, we build them with medical experts and life-care planners so the compensation reflects the true, lifelong cost of what you have endured.
What We Handle
Common Causes & Scenarios
High-Speed Vehicle Collisions
Serious car, truck, and motorcycle crashes are a leading cause of brain and spinal cord injuries. The forces involved can cause permanent damage even when the victim initially appears stable.
Falls from Height
Falls at construction sites, on defective stairways, or from unguarded ledges frequently cause traumatic brain and spinal injuries, particularly to older adults and workers.
Defective Products and Machinery
Dangerous products, unguarded industrial equipment, and failed safety devices can crush, burn, or amputate limbs. Manufacturers may be held strictly liable for these injuries.
Fires, Explosions, and Chemical Burns
Building fires, gas explosions, and exposure to dangerous chemicals can leave victims with severe burns requiring years of surgery and rehabilitation.
Pedestrian and Bicycle Impacts
When a vehicle strikes an unprotected pedestrian or cyclist, the result is often a catastrophic head or spinal injury. These victims bear the full force of the collision.
Workplace and Construction Accidents
Falling objects, equipment failures, and jobsite hazards can cause paralysis, amputation, and brain trauma, sometimes supporting claims against negligent third parties.

Frequently Asked Questions
What qualifies as a catastrophic injury?
A catastrophic injury is a severe injury that causes long-term or permanent impairment and typically prevents a person from returning to their normal life or work. Common examples include traumatic brain injuries, spinal cord injuries and paralysis, severe burns, amputations, and multiple fractures requiring extensive surgery.
How long do I have to file a catastrophic injury claim in California?
You generally have two years from the date of injury to file a personal injury lawsuit in California under Code of Civil Procedure section 335.1. If a government entity is involved, a claim may be due within six months. Because these cases require extensive investigation and expert analysis, it is important to start early.
Why are catastrophic injury cases valued so highly?
Catastrophic injuries often require a lifetime of medical care, rehabilitation, assistive equipment, home modifications, and in-home attendant care, and they frequently end a person's ability to earn a living. We work with life-care planners and economists to calculate the full present and future cost of the injury so nothing is left on the table.
What if a traumatic brain injury didn't show up right away?
Traumatic brain injuries are sometimes not diagnosed immediately because symptoms like memory loss, headaches, mood changes, and cognitive problems can develop over time. This is one reason to seek medical care promptly after any head trauma and to document symptoms, and it is why an experienced attorney working with medical experts is essential to proving the injury.
Can I still recover if I was partly to blame for the accident?
Yes. California follows pure comparative negligence, which means you can recover even if you were partly at fault, with your compensation reduced by your percentage of fault. Even a partial recovery in a catastrophic case can be substantial given the lifelong costs involved.
