Litigation opposition drafting in multistep workflows

Within Copilot Cowork, Harvey can surface briefs or motions from prior matters, identify strong arguments, expose weaknesses and gaps, and draft a counterargument outline as part of a coordinated litigation workflow.

Why the human is still essential here

Litigators must choose strategy, refine arguments, ensure accuracy and jurisdictional fit, and approve the final filing position.

How people use this

AI searches prior motions and oppositions from similar matters and surfaces reusable arguments, authorities, and structure for the current dispute.
