Thank you for your question.
If we are talking about an adult who never blocked out the abuse, she would have two years to bring a civil suit against her attacker.
With respect to a criminal action, in which she would not sue but would report the incident to the police, she could still do damage. After she reports incident, the police will investigate and confer with the District Attorney about whether charges should be pressed. The District Attorney can review the evidence in making the determination about whether the case is sufficient upon which to move forward. There is a very good chance that ten years after the fact, if there is no evidence, they may decide the case will be too difficult to prove.
