What Does an Expert Witness Actually Review in a Case? (A Behind-the-Scenes Look)

If you’ve ever worked with an expert witness—or are thinking about bringing one into a case—you’ve probably wondered:

Most attorneys know when to hire an expert and why they’re important. But what happens behind the scenes is often less clear.

So let’s pull back the curtain a bit and walk through what an expert witness is really reviewing, analyzing, and thinking about as your case moves forward.
