Question 1

How do I check whether a case citation is real?

Accepted Answer

CiteDiver resolves each citation against a verified corpus of U.S. federal and state court opinions and reports whether the case exists, which decision it resolves to, and whether the quoted proposition matches the opinion. Citations it cannot confirm are flagged rather than silently passed.

Question 2

Can CiteDiver detect AI-hallucinated citations in a brief?

Accepted Answer

Yes. That is the primary use case. Courts have sanctioned filings containing citations to cases that do not exist, and CiteDiver flags any cite that cannot be resolved to a real opinion in the corpus.

Question 3

Does CiteDiver tell me whether a case is still good law?

Accepted Answer

Yes. It surfaces treatment signals — overruled, questioned, distinguished — along with subsequent history and reversal flags, so an authority that exists but has been undermined is not mistaken for a safe cite.

Question 4

What is the $10,000 anti-hallucination guarantee?

Accepted Answer

For citations the system verified or inserted, if a court flags the authority as nonexistent or fabricated, CaseDiver pays $10,000. An active subscription is required at the time of filing.
