No, the fact that she conversation appears in a court record does not mean it was involved in a violation of any law (and you probably meant civil or criminal law; not all civil cases involve even alleged violations of agreememts—contracts isn't the whole civil law universe.)
Courts may exist to determine if a violation of law occurred, but sometimes the answer is “no”. (And even if it is yes, the specific conversation at issue may not have.)
