How to Run a Conflict Check at a Small Law Firm (Without Enterprise Software)

Conflict of interest screening is one of those obligations every lawyer knows about and most small firms handle badly. Not out of negligence — out of friction. When your "system" is a spreadsheet, a filing cabinet, and someone's memory, things slip through.

The consequences of a missed conflict are severe: disqualification from a case, malpractice exposure, and potential bar discipline. Yet the tools designed to prevent this are overwhelmingly built for firms with 50+ attorneys and budgets to match.

This article breaks down how small firms can build a reliable conflict checking process today — and where AI is starting to close the gap between what solo practitioners can afford and what large firms take for granted.

Why Manual Conflict Checks Fail

The typical conflict check at a small firm looks something like this: a lawyer gets a call from a prospective client, writes down the name, and searches through their email, case files, and maybe a spreadsheet of former clients. If nothing rings a bell, they take the case.

The problem isn't laziness. It's that manual searches rely on exact name matching, human memory, and consistent record-keeping — three things that break down quickly in a busy practice.

Consider how many ways a single entity can appear across your files: "Johnson & Associates," "Johnson Associates LLC," "Dave Johnson's company," or just "Johnson." A manual search for one variation will miss the others. A 2023 study by the American Bar Association makes clear that the duty to check for conflicts extends to all parties and their related entities — not just the named client.

The Minimum Viable Conflict Check Process

If your firm doesn't have a formal conflict screening workflow, start here. This isn't perfect, but it's dramatically better than relying on memory.

Step 1: Maintain a central contact register. Every person and entity your firm has ever represented, opposed, or had significant contact with should be in one searchable list. A spreadsheet works. A database is better. The key is that it exists and is updated every time you open or close a matter.

Step 2: Search before you engage — every time. No exceptions. Even if the prospective client was referred by someone you trust. Even if the name doesn't sound familiar. Run the name against your register before the retainer is signed.

Step 3: Search for variations. Don't just search for "Smith." Search for "Smith," "Smyth," "Smith & Co," "Smith Associates," and any known related entities. This is where manual processes break down most — and where AI-powered conflict screening starts to offer a genuine advantage.

Step 4: Document the check. Record what you searched, when, and what you found (or didn't find). If a conflict question ever arises, your log is your evidence that you took reasonable steps. The ABA's guidance on competence and diligence supports the position that documented screening is part of a lawyer's duty of care.

Where Spreadsheets Break Down

A spreadsheet-based system works when you have 50 contacts. It starts to crack at 200. By the time you have 500+ contacts across multiple years of practice, the friction of maintaining and searching it becomes its own problem.

Common failure points include:

• Inconsistent data entry. One attorney logs "Robert Smith" while another logs "Bob Smith." Neither logs the entity name.
• No relationship mapping. Your register has the client's name but not their spouse, their business partner, or the opposing party from a prior matter.
• Stale data. People leave the firm and take their institutional memory with them. The spreadsheet hasn't been updated in months.

These aren't edge cases. They are the normal state of affairs at most small firms. And each one represents a scenario where a conflict could be missed — not because no one checked, but because the system wasn't capable of catching it.

How AI Changes Conflict Screening

AI-powered conflict checkers approach the problem differently from a spreadsheet search. Instead of relying on exact string matching, they use natural language understanding to recognise that "Smith & Associates" and "Smith Associates Ltd" are likely the same entity.

More importantly, they can search across your entire matter and contact history simultaneously — not just a single register, but every document, email, and case file your firm has ever uploaded. This is the difference between checking a list and checking your entire institutional knowledge base.

LexVault's conflict checker, for example, runs an AI-powered screen against all contacts and matters in your firm's database, handles name variations and abbreviations automatically, and returns results with full matter context so you can make an informed decision. Every check is logged for compliance purposes — which satisfies the documentation requirement without any extra work.

This doesn't replace professional judgement. You still decide whether a potential match is a genuine conflict. But it dramatically reduces the chance of missing something that should have been caught.

Practical Steps You Can Take This Week

If your firm doesn't have a formal conflict screening process, here's what to do right now:

1. Audit your current system. How do you currently check for conflicts? Who is responsible? Is there a documented process, or does it depend on individual habits?
2. Create or update your contact register. Export your case management data, email contacts, and any existing client lists into a single searchable file. Deduplicate where you can.
3. Write a one-page conflict check policy. It doesn't need to be elaborate. It needs to state: who checks, when they check, what they search, and where the result is logged.
4. Evaluate whether your current tools are adequate. If you're still searching a spreadsheet, consider whether an AI-powered solution would catch conflicts that your current process misses.

The cost of a missed conflict is always higher than the cost of a better process. The only question is whether you find out before or after it matters.
