Coding Agents in Action at Law Firms
From Rollout to Real Legal Work
When Cederquist, one of Sweden's leading law firms, rolled out Vesence, adoption climbed until the vast majority of lawyers were using it every week. In this case study, Johan Lidström, Partner at Cederquist, deep dives into what changed, what the two teams built together, and what coding agents mean for the firm.
The story is less about a single feature and more about a shift in how legal work gets done, and where the frontier of legal AI now sits.
Lawyers Used the Product in Ways We Thought Weren't Possible
The most striking part of the rollout was watching Cederquist's lawyers reach for capabilities Vesence had never built: advanced PDF editing, bespoke workflows, and complex document operations. The lawyers simply asked the agent, and it coded them up on the spot.
This is the promise of a coding agent rather than a fixed feature set. Vesence doesn't need to anticipate every tool a firm will ever want. When the work calls for something new, the agent builds it, so the product keeps expanding to meet the actual demands of practice.
Choose the Tool Whose Output You Can Actually Trust
The reason for the adoption wasn't that Vesence promised more. It was that Vesence only shipped what lawyers could trust, and built reviewability into every capability from the start. Lawyers can see exactly what the agent did, verify it, and redirect it when needed.
Trust isn't a marketing claim: it's a design choice. And it's the choice that makes the role shift real: when the output is verifiable, lawyers can move from doing every step by hand to reviewing and directing the work of agents.
Sitting on the Frontier Is Now a Competitive Advantage
The firms that win the next decade won't be the ones running legacy legal AI. They'll be the ones whose leadership invests in being early, working alongside the technology as it matures rather than waiting for it to settle.
Cederquist's bet was that being on the frontier matters. That bet is why their lawyers are already building workflows most firms haven't imagined yet, and why the gap between frontier firms and everyone else is starting to compound.
