arXiv:2606.18728v1 Announce Type: new Abstract: Civil litigation is inherently a life-cycle process: what a lawyer drafts on day one constrains what unfolds at trial months later. Yet existing legal benchmarks evaluate isolated subtasks, and prior legal-agent simulators reinitialize each scenario from shared ground truth, leaving cross-stage causal dependencies unmodeled. We present LegalWorld, a life-cycle interactive environment that models Chinese civil litigation as a causally connected state chain of five stages (seven sub-scenarios), grounded in 75,309 paired Chinese civil judgments.

The proliferation of advanced language models enables the creation of more sophisticated and interactive agent environments, moving beyond isolated task evaluations in AI development.
This development allows for the simulation of complex, multi-stage legal processes, which is crucial for training and evaluating autonomous legal AI agents capable of handling real-world scenarios.
Existing legal AI benchmarks, which often assess isolated subtasks, are augmented by a new paradigm that models the causal dependencies across an entire life-cycle process, offering a more holistic evaluation framework.

Legal professionals may begin to delegate more complex, multi-stage tasks to AI agents capable of understanding life-cycle dependencies.
The development of highly effective legal AI agents could significantly reduce the cost and time associated with civil litigation, increasing access to justice.
The legal industry's structure could be transformed, with AI agents handling routine lifecycle processes, allowing human lawyers to focus on high-value, strategic, or ethically complex cases.
