LexPilot: Benchmarking the Proactive Interaction Ability of Legal LLMs with Laypeople in Chinese Civil Case Consultation

To address this gap, we introduce LexPilot, a benchmark linking proactive legal interaction to claim-level verdict prediction using authentic Chinese civil judgments.

Key points

  • Large Language Models (LLMs) have greatly assisted legal professionals.
  • However, our empirical studies reveal that, when faced with underspecified consultations from non-experts, current LLMs often produce irresponsible responses with limited utility despite lacking sufficient case details for definitive conclusions.
  • To better assist laypeople, legal LLMs must identify focal points of dispute and proactively elicit crucial context from users.
  • Unfortunately, existing data resources often focus on interaction and response quality, offering limited insight into how proactive interaction affects LLMs' downstream claim-level judgment prediction in actual civil cases.
