I'm Lucy, and I'd be happy to answer your questions today.
Statements made in court are privileged from being used as the basis for a defamation action. Also, defamatory statements are, by definition, false. The alleged victim can't get a defamation judgment against you if you introduce truthful information in court.
One objection they may try to enter is hearsay - an out-of-court statement being used to prove the truth of the contents of the statement. However, you're actually introducing her statements NOT to prove they're true. You're trying to prove that she lied. So, you should be able to overcome a hearsay objection. They might also try to object on relevance, but you can counter that with the fact that the witness's credibility is a key issue for the jury to decide. The fact that she has a pattern of false claims IS probative of her truthfulness in your case.
Usually, the witness would be asked questions about the prior claims, and then you could show her the prior reports to refresh her memory if she claims she doesn't know, or you can ask the judge to admit them into evidence. But there has to be a foundation, which means talking to the witness about the evidence before you give it to the court.
