Conflict checks in law firms with a procedure small firms can keep
Last updated October 19, 2026
Every firm runs some kind of conflict check. In many small practices it is a search of the billing system, an email to the other partners asking whether anyone knows the name, and a memory of who sat across the table five years ago. That works until the day it does not, usually when a former client calls to ask why you are now suing their subsidiary. This article lays out a conflict procedure a firm of one to twenty lawyers can run on every new matter, explains the ABA Model Rules it rests on in general terms, and shows where software helps and where an attorney still has to decide.
Why informal conflict checks break down
Informal checks fail for predictable reasons. The firm's records hold the client's name but not the names of the opposing parties, the insurer, the guarantor or the spouse. Names are entered differently each time, so a search for "Acme Holdings LLC" misses "ACME Holdings, L.L.C." and "Acme Hldgs". Lateral hires bring a history that never made it into the system. And the check happens after the consultation, when the lawyer has already heard confidential facts from the prospective client.
None of these failures come from bad intentions. They come from a process that depends on memory and on one person remembering to ask. A written procedure fixes most of them, and it also gives the firm something to show a malpractice carrier or a disciplinary authority if a conflict is ever questioned.
- Records that store only clients, not adverse and related parties.
- Name variants, typos and corporate families that a plain search misses.
- Lateral hires and of counsel lawyers whose prior matters are not in the database.
- Checks run after confidential information has already been received.
- No written record of who cleared the conflict and on what basis.
The ABA Model Rules behind the check
Most states base their conflict rules on the ABA Model Rules of Professional Conduct, though the wording and comments differ from state to state, so your own jurisdiction's version is the one that binds you. Three rules carry most of the weight.
Rule 1.7 covers conflicts with current clients. A concurrent conflict exists when one representation is directly adverse to another current client, or when there is a significant risk that the lawyer's responsibilities to another client, a former client, a third person or the lawyer's own interests will materially limit the representation. Some of these conflicts can be handled with each affected client's informed consent, confirmed in writing, provided the lawyer reasonably believes competent and diligent representation is still possible. Some cannot be consented to at all, such as asserting a claim by one client against another in the same litigation.
Rule 1.9 covers duties to former clients. A lawyer who represented a client in a matter may not later represent another person in the same or a substantially related matter whose interests are materially adverse to the former client, unless the former client gives informed consent, confirmed in writing. The rule also restricts using or revealing information relating to the earlier representation to the former client's disadvantage.
Rule 1.10 covers imputation. While lawyers are associated in a firm, a conflict that would prohibit one of them from taking a matter under Rules 1.7 or 1.9 generally prohibits all of them, with exceptions such as purely personal interest conflicts and, under the Model Rule, certain lateral hire conflicts that are handled through timely screening and written notice to the former client. Many states have their own version of the screening exception, and some do not allow it at all.
Two related rules matter for intake. Rule 1.18 protects prospective clients, so information heard in an initial consultation can create a conflict even if the firm is never hired. And Rule 1.8 lists specific personal interest conflicts, such as business transactions with clients, that a name search will never catch.
A conflict procedure for a small firm
The procedure below fits a small firm with no dedicated conflicts clerk. It assumes one person, often a paralegal or legal assistant, runs the search and one attorney signs off.
Collect names before the consultation
Use a short intake form that asks for every name connected to the matter before a lawyer hears the facts in detail. The prospective client's full legal name and any former names, related entities such as parents, subsidiaries and affiliates, the opposing parties and their counsel, insurers, co-defendants, guarantors, and key witnesses where known. For family matters, add the spouse or partner, former names and children's names. For estate matters, add beneficiaries, fiduciaries and family members likely to contest.
Limit what you hear first
Tell prospective clients at the first contact that you need names to check conflicts and that they should not share detailed facts until the check is complete. This is the simplest way to reduce Rule 1.18 exposure, and it costs nothing.
Search every name against every record
Search each name against current clients, former clients, adverse parties in past and open matters, related parties and prospective clients the firm declined. Search variants as well: abbreviations, punctuation differences, maiden and married names, and the corporate family. Record the search terms used, not just the results.
Review the hits with judgment
Most hits are noise, a common surname or a different company with a similar name. Each real hit needs a short analysis: is the person a current client, a former client, or a prospective client; is the new matter directly adverse or substantially related; is there a material limitation risk. The answer decides whether the matter is clear, needs consent, needs a screen, or must be declined.
Document the decision
Write down who reviewed the results, what was found, what was decided and why. If consent is needed, get it in writing from each affected client before work starts, with enough explanation of the risks for the consent to be informed. If a screen is used, record when it was put in place and who is screened.
Add the new names to the database
Once the matter opens, enter every name collected at intake as a client, adverse party or related party. A conflict system is only as good as the last intake form someone bothered to enter.
Check again when the matter changes
New parties appear during litigation: a third-party defendant, an intervenor, a new insurer, an acquiring company. Run a fresh check whenever a party is added, and when a lateral lawyer joins the firm, check their prior matters against your open ones.
What your conflict records need to hold
A firm's conflict database is more than a client list. At minimum each matter should store the client and its related entities, every adverse party, opposing counsel, other related parties such as insurers and co-parties, the responsible attorney, the matter type, and the open and close dates. Declined prospective clients belong in the same records, with a note on what information was received.
- Client name, former names and related entities.
- Adverse parties and their related entities.
- Opposing counsel and other related parties.
- Matter description, practice area and responsible attorney.
- Open and close dates, and whether the client is current or former.
- Declined prospective clients and what they disclosed.
Where software helps and where it stops
Software makes the search part fast and consistent. Fuzzy matching catches spelling variants, punctuation and abbreviations that a plain search misses. A good tool searches clients, adverse parties and related names at once, groups hits by matter, and produces a report an attorney can sign. It also adds intake names to the database automatically, which removes the step most small firms skip.
What software cannot do is decide. Whether two matters are substantially related, whether a material limitation exists, and whether a conflict is consentable are legal judgments. A tool that tells you a matter is cleared without an attorney's review is giving you false comfort. The right setup puts the search in software and the decision with a lawyer, with a record of both.
A conflict check checklist
Use this list on every new matter and every added party.
- Collect all names on the intake form before hearing detailed facts.
- Search every name and its variants against clients, adverse parties and related parties.
- Include former clients, declined prospective clients and lateral hires' prior matters.
- Review each real hit for direct adversity, substantial relationship and material limitation.
- Obtain written informed consent where the conflict is consentable.
- Record any screen, with the date and the screened lawyer.
- Document who cleared the matter and why.
- Enter every new name into the conflict records when the matter opens.
- Rerun the check when parties change.
How Jural runs conflict checks
Jural connects intake and conflict search in one workspace. Legal intake software collects the client, related entities, adverse parties and other names through practice-area forms, and law firm conflict check software searches every name with fuzzy matching across clients, adverse parties and related names in the firm's records. The result is a conflict report grouped by matter, with each hit showing why it matched, ready for an attorney to review and sign off.
Jural supports the check and does not decide it. The attorney records the decision, the reason, and any consent or screen, and the activity log keeps the record. Firm and Enterprise plans run the search across the whole firm, and per-matter access walls keep screened lawyers out of the matters they must not see. Client documents are never used to train AI models.
