Every law firm is using AI. Almost none of them can prove they supervised it properly.

Courts are drawing hard lines. Solicitors who can demonstrate meaningful human review and professional oversight will be protected. Those who cannot face regulatory scrutiny, malpractice claims, and professional discipline.

Yet the frameworks for this supervision do not exist. AI-assisted legal work sits in a regulatory gap: courts expect human oversight, but there is no defined process for it. Traditional file notes are retrospective and subjective. Email chains are fragmented and incomplete. Most critically, there is no coherent way to prove to a regulator that the work was supervised at all.

Compliance infrastructure for AI-assisted legal practice. A system that captures the entire supervision process in a formal, auditable record.

Countersigned.ai implements a five-layer compliance framework that covers every stage of AI-assisted legal work: from initial generation through to final sign-off. Each layer is documented, timestamped, and signed. The result is a supervision transcript that a solicitor can hand to a court or regulator and say: this is exactly what happened, and I take professional responsibility for it.

This is not a workaround. It is a new standard of practice.

From silence to proof.

• From silent AI use to transparent, documented supervision
• From retrospective file notes to contemporaneous audit trails
• From hoping the regulator never asks to proving supervision actually happened
• From undefined practice to a formal five-layer compliance framework

"The firms that can demonstrate supervision will thrive. The ones that cannot will face consequences. Countersigned builds that proof."

If it works in the hardest market, it works everywhere. We are building this for UK regulated legal practice first, where the bar is highest: SRA regulation, professional liability, court disclosure, and the scrutiny of opposing counsel.

The compliance framework is jurisdiction-agnostic. A law firm in Singapore, Toronto, or New York can use it. But we are testing the steel in London, where the requirements are most demanding.

This is enterprise software for regulated professionals. It is not flashy. It is not trying to replace lawyers. It is trying to protect them.

Countersigned.ai is in early access. We are building this with early adopters: regulatory specialists, practice managers, and forward-thinking partners.
