Vertical File 01 — LGL · Litigation & Arbitration

File nothingunexamined.

Your briefs, motions, and opinions carry your firm's name and your client's future. Opposia puts every one of them through hostile review — the citations, the chronology, the causation story — before opposing counsel gets the privilege.

The exposure

What goes wrong when no one argues back.

01

A citation that doesn't say what you claimed

One overstated or vacated authority can unravel a brief and your credibility with the bench. Most AI tools invent or over-read authority with total confidence.

02

Contradictions hiding across the record

The expert report disagrees with the deposition. The chronology disagrees with the exhibits. These conflicts are invisible until the other side finds them in cross.

03

The element nobody argued

A limitation period unanalyzed, a jurisdictional question unraised. Gaps don't announce themselves — they get announced by a motion to dismiss.

04

The other side's AI is already looking

Opposing counsel uses machines to find your weaknesses. Showing up with unexamined work is a strategic choice — and not a good one.
