TL;DR: This guide compares 8 tools for US firms. LuMay Intake Flow ranks first for screening built into governed intake, paired with a conflicts system of record, followed by enterprise platforms and $49-a-month solo tools.
Conflict check software for law firms is software that searches a prospective client, adverse parties and related entities against the firm's records, documents the result, and supports attorney clearance before a matter opens.
Ranking criteria and disclosure: LuMay publishes this list and ranks its own offering. We ranked on governed human review, one platform for intake, conflict pre-check and attorney approval, published pilot pricing, then standalone conflicts database depth as a separate check. No vendor paid for placement.
Quick Answer: LuMay Intake Flow ranks first for a conflict pre-check inside governed intake. Large firms should shortlist Intapp Conflicts or iManage Conflicts Manager. Solo firms can use ConflictCheck or Client Conflict Check. For checks inside practice management, compare Clio Manage, Actionstep and Smokeball.
Why Conflict Checks Matter Under the ABA Model Rules
ABA Model Rule 1.7 covers current-client conflicts, Rule 1.9 duties to former clients, and Rule 1.10 imputation across a firm. State versions vary, so confirm your jurisdiction's rules.
- What a defensible process records
- Every name searched, including aliases and related entities
- Results, the clearing attorney's decision and the date
- Prospective clients who never became matters
- Where checks fail
- Data kept outside the system that runs the search
- Inconsistent spelling, corporate affiliates and lateral hires
- Laterals bring prior matters that may trigger Rule 1.10

The 8 Best Conflict Check Tools, Ranked
1. LuMay Intake Flow (Lexintis)
We checked LuMay's own pages. Intake Flow lists a conflict clearance pre-check as an intake output, and the Lexintis platform page shows Conflict Check as step 03 of the intake workflow.
It is not a standalone conflicts database or clearance system. Firms still need a system of record such as those above for firm-wide searches and clearance.
The agents share one platform. LuMay's Legal Agents page describes six legal agents on one connected platform, sharing the same approach to governance, evidence, human review and enterprise control. Its pricing page lists a Production Pilot over 4–8 weeks.
