Frequently Asked Questions

Can lawyers use AI in their legal work?
Yes — no US state bar or Canadian law society bans generative AI. Regulators including the ABA (Formal Opinion 512) and the Law Society of Ontario apply existing duties: competence, confidentiality, verification of output, supervision, and reasonable fees.
What is the biggest risk of lawyers using AI?
Unverified output. Language models fabricate case citations and misstate law, and courts have sanctioned lawyers — Mata v. Avianca (S.D.N.Y. 2023), Park v. Kim (2d Cir. 2024), Zhang v. Chen (B.C.S.C. 2024) — for filing AI-generated authority without checking it.
Do lawyers have to disclose AI use to courts?
In some courts, yes. Several US federal judges require certifications by standing order, and Canadian courts including Manitoba's Court of King's Bench and the Federal Court of Canada require declarations for AI-generated content. Always check the current rules of each court.
Can law firms bill hourly for AI-assisted work?
Only for time actually spent. ABA Op. 512 confirms AI efficiency gains belong to hourly clients, which is a major driver of the shift toward flat and value-based fees for commoditizable work in both the US and Canada.
Which legal tasks does AI handle well today?
First drafts of routine documents, clause retrieval and consistency checks, summarization of supplied materials, first-pass discovery and diligence review, and brainstorming — always as an intermediate product a lawyer verifies before it matters.
Is client data safe in AI tools?
It depends entirely on the tier and terms. Enterprise deployments with contractual no-training commitments, retention controls, and SOC 2-grade security can satisfy confidentiality duties; default consumer chatbots that may retain and train on inputs generally cannot for client information.

This article is general information, not legal or ethics advice. Professional-conduct rules on AI are evolving and vary by jurisdiction — always verify current requirements with your state bar, law society, or regulator before adopting any AI workflow.
