The law requires that you file a lawsuit within a specified period of time depending on the nature of the claim and the entity that caused your injury. This is referred to as the statute of limitations. Generally, for personal injury claims, the statute of limitations in Alabama is two years from the time of injury. The period of limitations usually runs from the time the injury occurred. Special rules, however, apply in some situations. Under the discovery rule, if you suffered a hidden injury, the period of limitations runs from when the injured person knew or should have known they were injured. Special rules may also apply to children, to individuals who are mentally impaired or who leave the state for certain reasons such as military service. You should consult an attorney about the specific limitation period for your claim.
