Hallucinated Citations Reach Filing

The AI content problem is getting harder to solve. Here's what professionals in legal & compliance face every day.

A legal brief with a section circled in red, paperclipped to a detection report, illustrating a flagged citation before filing

AI-hallucinated citations in legal briefs

Attorneys have submitted briefs with fabricated case citations generated by LLMs. Courts have sanctioned lawyers for unverified AI output.

Contract authenticity disputes

AI-drafted contracts may contain subtle inconsistencies not obvious to human review. Establishing original authorship is increasingly complex.

Evidence integrity challenges

Deepfake audio, synthetic video, and AI-generated documents are being submitted as evidence, requiring new verification capabilities.

Regulatory compliance documentation risk

AI-generated compliance reports and filings that don't reflect genuine organizational analysis create significant liability exposure.

Frequently Asked Questions

Are Aiscern reports admissible in legal proceedings?

Our reports are designed to be audit-trail documents, not expert witness testimony. They provide technical evidence that supports — not replaces — expert analysis. Consult with your legal team on jurisdiction-specific admissibility.

Can Aiscern detect AI text in legal documents with heavy boilerplate?

Legal documents contain significant boilerplate that may appear in AI training data. Our ensemble is tuned to distinguish genuine AI generation from standard legal language. Confidence scores below 62% indicate ambiguous sections.

What security certifications does Aiscern hold?

We are actively working toward SOC 2 Type II compliance. Current security measures are documented at /security. Enterprise clients can request our security assessment documentation.

Is there attorney-client privilege protection for submitted documents?

Documents are processed ephemerally — not stored beyond the session unless you explicitly save a report. We do not train on submitted content. For privileged material, we recommend our Enterprise plan with enhanced data handling agreements.

Can we run detection on documents in languages other than English?

English, Spanish, French, German, and Portuguese are supported with high accuracy. Other languages may return results in the uncertain confidence range. Legal documents in non-supported languages are best verified with English translation first.
