A conflict of interest in legal practice arises when a lawyer's representation of one client is materially limited by responsibilities to another client, a former client, a third person, or the lawyer's own interests — requiring disclosure, consent, or withdrawal from the conflicted representation.

In the legal AI context, confidentiality refers to the obligation of lawyers and legal AI vendors to protect client information from unauthorized disclosure, and to the technical and contractual measures that implement that protection when client data is processed by AI systems.
CapabilityConflict check AI is software that automates the identification of potential conflicts of interest by searching a firm's client and matter database against new prospective client or adverse party information.
SecurityAn engagement letter is a written agreement between a lawyer and client that defines the scope of the legal representation, fee arrangements, billing practices, and terms governing the attorney-client relationship — and increasingly, the terms under which AI tools may be used in the representation.

Conflict of interest rules are among the most consequential professional conduct provisions. Representing a client despite a disqualifying conflict exposes the lawyer to disqualification motions, fee disgorgement, malpractice claims, and disciplinary proceedings. In law firm mergers, lateral moves, and multi-office practices, managing conflicts is operationally demanding.
The Model Rules of Professional Conduct distinguish between direct conflicts (concurrent representation of clients with adverse interests under Rule 1.7) and successive conflicts (representing a client adverse to a former client in a substantially related matter under Rule 1.9). Different consent and waiver standards apply to each.
Conflicts can arise from: directly adverse parties in current matters; business interests of the lawyer or firm; personal relationships with parties or witnesses; prior representations by laterally hired attorneys; corporate affiliates of existing clients; and court appointments that conflict with existing client representations.
A conflict that is identified is manageable — the lawyer can seek consent, screen the conflicted attorney, or decline the representation. A conflict that is identified only after work has begun creates far greater problems. Prevention through systematic conflict checking is the professional standard.
AI-assisted conflict checking is available through practice management platforms. Clio and MyCase include conflict check features that search existing matter and contact databases against new matter information, flagging potential matches for attorney review.
The AI dimension in conflict checking extends beyond simple name matching. More sophisticated tools apply fuzzy matching, corporate relationship analysis, and affiliate identification to surface conflicts that would be missed by exact-string searches. These tools reduce the risk of missing a conflict involving a commonly named client, a subsidiary of an existing client, or a corporate entity with multiple names.
For law firm AI tools broadly, conflict risk has an additional dimension: using an AI tool that has "seen" confidential information from a client adverse to a current client raises the question of whether information in the AI's context or memory could create cross-matter leakage. This is why enterprise legal AI tools include strict matter separation, access controls, and audit logging — to prevent inadvertent information sharing between matters in the same AI environment.
