The purpose of personal injury claims is to compensate the injured party for their losses and damages, such as: medical expenses, lost income, pain and suffering, and loss of enjoyment of life. However, personal injury claims are not always simple or straightforward. They involve complex legal issues that require the expertise and guidance of a qualified personal injury lawyer. One of the most important reasons to conduct a thorough investigation in personal injury claims is to establish the liability of the responsible party. Liability is the legal term for fault or responsibility for causing an injury. In order to succeed in a personal injury claim, the injured party must prove that the other party owed them a duty of care, breached that duty of care, and caused their injury as a result.
