I am so sorry this happened to you.
As far as I know, any civil action is barred by the statute of limitations. To sue for sexual abuse of a minor one has to commence the action within 3 years of the incident, or within 3 years of when the alleged victim realized there was some injury. That 3 year window is tolled until the child reaches 18. You are outside that window.
But a criminal action for sexual abuse of a minor can be brought anytime. However, if 27 years or more have elapse since the incident there must be independent evidence that supports the allegations. Speak with the district attorney's office in the county where it happened.
