Negligent security cases fall under the larger umbrella of premises liability cases. Premises liability cases are a type of personal injury claim and, thus, are subject to a strict statute of limitations. This means that, unless you file a claim within the period of time outlined in the statute of limitations, you may forever give up your right to bring a lawsuit. However, while you have time to bring a claim, it is generally better to contact a lawyer as soon as possible. That way, your attorney will have ample time to investigate the incident while evidence and witnesses are still easy to locate.
