Right away. You should consult a personal injury attorney as soon as possible after being injured. In most cases there are time limits for filing personal injury claims after an accident or injury occurs, and if this deadline passes, your claim could be dismissed. In addition, finding witnesses and gathering and preserving evidence to support your case becomes more difficult the longer you wait. The sooner you hire the right personal injury attorney, the closer you are to getting the compensation you deserve for your pain and suffering and monetary losses.
