If you are injured you must be aware of the time limitations on your claims. Personal injury claims must be filed within three (3) years of the incident. Medical malpractice claims must be filed within two (2) years and six (6) months of the medical error, subject to some time extensions for conditions you discovered much later. It is important to hire a lawyer immediately to make sure you do not miss any deadlines for filing your claims. Attorney advertising. Prior results do not guarantee a similar outcome.
