What is “Causation” in a California Personal Injury Case?

In a personal injury claim, the term causation means:

  • The link between what someone did (or didn’t do) and the injuries you ended up with.

Causation is just one part of negligence, which is the legal standard for liability–the legal responsibility for covering your injuries and other losses from the accident. If you’ve been injured in an accident, figuring out what caused it can be challenging. That’s where our California personal injury lawyers at Maison Law can step in to help.

How is Causation Decided After an Accident?

Figuring out causation is really just figuring out the “why” behind your injuries—why the accident happened, why you got hurt, and why the other person is responsible. No single piece of evidence decides it. Instead, it comes together like a puzzle. Here’s how that usually happens:

  • Starting with the basic facts. Everyone looks at what happened in those moments leading up to the accident. That might include photos, videos, witness statements, or the physical layout of the scene. These pieces help show how things unfolded.
  • Connecting your injuries to the accident. Your medical records help tell the story of what injuries you have and when they showed up. If the injuries match the type of accident you were in, that strengthens the connection between the two.
  • Looking at the other person’s actions (or lack of action). Did someone ignore a safety rule? Forget to clean up a spill? Speed through an intersection? Leave equipment unsecured? The clearer their behavior is, the easier it is to show it led to what happened to you.
  • Bringing in experts when things get complicated. Sometimes doctors, engineers, or accident reconstruction specialists step in to explain how the accident caused the injuries. Their insight helps fill in any gaps.
  • Considering how the injury changed your life. Your day-to-day experience matters too. Notes about pain, mobility, sleep, missed work, or activities you can’t do anymore help show the impact the accident had on you personally.

When everything is put together, the goal is simple: show a clear, believable link between the accident and your injuries. That’s what causation is all about—and having someone who knows how the process works can make the whole situation easier.
