    What is a personal injury case?

    A personal injury case is a legal dispute that arises when one person suffers harm from an accident or injury, and someone else might be legally responsible for that harm. Personal injury cases typically involve injuries to the body, mind or emotions, and not property. Examples include car accidents, medical malpractice, slip and fall accidents, toxic exposures and more.

    If you have been injured by someone or a company's negligence or wrongful actions, you may have a personal injury case. It is important to speak with an experienced personal injury attorney to determine the strength of your case and your legal options.

    The value of a personal injury case can vary depending on a number of factors, such as the severity of the injury, the amount of medical expenses, lost wages, and pain and suffering. An experienced personal injury attorney can help you determine the potential value of your case. It is critical to speak with an experienced attorney to maximize the value of your case.

    The length of time it takes to settle a personal injury case can vary depending on a number of factors, such as the complexity of the case, the availability of insurance coverage, and the willingness of the parties to negotiate a settlement. Some cases may be resolved in a matter of months, while others may take longer. The harder your attorney works on the case, the more likely it settles quickly.

    Negligence is the failure to exercise the degree of care that a reasonably prudent person would use in similar circumstances. To prove negligence in a personal injury case, your attorney must show that the defendant did something that a reasonably careful person would not do, and that it caused a physical injury.
