A controversy before a court or a "lawsuit" is commonly referred to as litigation. If it is not settled by agreement between the parties it would eventually be heard and decided by a judge or jury in a court. Litigation is one way that people and companies resolve disputes arising out of an infinite variety of factual circumstances.
The term "litigation" is sometimes to distinguish lawsuits from alternate dispute resolution methods such as "arbitration" in which a private arbitrator would make the decision, or mediation which is a type of structured meeting with the parties and an independent third party who works to help them fashion an agreement among themselves. Modern Product Litigation is a complex and difficult process. The proof or dis-proof of product defects and their involvement in personal injury are fought vigorously by both sides in any case.
Whether or not you plan on litigating, a litigation lawyer would be able to determine what the best approach for your case is and advise you on the next steps to take. Even if you decide to settle out of court, a litigation attorney will help you get the settlement you deserve or otherwise assure that your legal rights are being protected.
