What are the steps that I need to take to pursue a civil law suit in a rape case and what are the statue of limitations?

You will need to consult an attorney who specializes in personal injury law. You should be aware that the sole remedy available in such an action is money damages. Your attorney will help you evaluate whether the would-be defendant is likely to have enough money to make such an action worthwhile. The intentional-tort statute of limitations would generally apply -- one year.
