One thing you'll always need before proceeding with a birth injury case is a clear-cut medical diagnosis of the problem from a reputable doctor. Only then should you start the process of researching and selecting a capable legal specialist for your lawsuit.
Birth injury claims are never easy to prosecute, so you need someone on your side with the proper experience, resources, accreditations, and education to move the case briskly through the courts. Your lawyer should be aggressive, always placing your needs first.
