Do paralegals bring conflicts when they switch firms?
Staff-side conflicts: a paralegal's conflict of interest is not imputed to the firm under the model text of Rule 1.10(a), but Comment [4] still ordinarily expects the person to be screened from the matter.
Here is the staff-hire check.
Yes — a paralegal who switches firms can carry a paralegal conflict of interest in the door with them.
What they do not carry, under the ABA's model rules, is imputation: Comment [4] to Rule 1.10 says a nonlawyer's conflict is not imputed to the firm the way a lawyer's is.
The same comment expects that person ordinarily to be screened from the matter, so run the check on every hire — staff included.
Do non-lawyer conflicts get imputed to the firm?
Start with the rule that makes lateral hiring so fraught.
Under the model text of Rule 1.10(a), "While lawyers are associated in a firm, none of them shall knowingly represent a client when any one of them practicing alone would be prohibited from doing so by Rules 1.7 or 1.9" — one lawyer's conflict becomes every lawyer's in the firm, subject to the rule's exceptions.
That imputation is the engine behind the lateral attorney conflicts check, and it is why a single attorney hire can change who your whole firm may represent.
Comment [4] to the same rule then draws the staff line: the rule in paragraph (a) "does not prohibit representation by others in the law firm where the person prohibited from involvement in a matter is a nonlawyer, such as a paralegal or legal secretary."
A new hire's conflict therefore stays with the paralegal; it does not spread to your lawyers the way an attorney's does.
That is imputation only — it is not a clean bill of health.
The same comment adds that "Such persons, however, ordinarily must be screened from any personal participation in the matter."
Not imputed — ordinarily screened: your lawyers may take the client, and the conflicted paralegal is ordinarily kept out of any personal participation in that matter.
Comment [4] also carves out a second exception to imputation: a lawyer whose conflict comes from events before they became a lawyer — the rule's own example is "work that the person did as a law student."
Not imputed, ordinarily screened.
For a firm hiring staff both comments point the same way: the person who is conflicted is the one ordinarily screened, whether the conflict came from staff work or from work done before they were a lawyer — which is why a candidate's history question starts at their first legal job, not their first lawyer job.
So under the model text a staff hire is the narrower exposure: the conflict is not imputed the way a lateral attorney's is.
It is not a zero risk — the conflict attaches to the person, the person sits on your payroll, and the last section of this page covers how a staff conflict can still end up in front of a tribunal.
The search itself feeds the same conflicts system as everything else in hiring for your law firm — same search, narrower rule behind it.
What do ABA Informal Op. 88-1526 and state cases say?
We cannot tell you what they say, and our research will not pretend otherwise.
This page's research verified the parts of Rule 1.10 and its comments quoted here; it did not verify the text of ABA Informal Op.
88-1526, and it did not verify any state court decision on screening nonlawyer staff.
Paraphrasing an opinion we did not read would put words into a source your conflicts file might someday be measured against, so this page leaves both alone.
Two things the verified record does support.
First, an ABA opinion interprets the ABA's model rules — it is not binding on any state, so even a correctly cited informal opinion is a starting point for the question, not the answer to it.
Second, states adopt their own versions of these rules, and which states accept which screening practices is exactly what our research could not verify: states differ.
The rules that govern your firm are your state's, and whether your state's version of Rule 1.10 treats nonlawyer screening the way the model comment does is a question for your state bar's ethics counsel.
On the "state cases" half of the question, the model comments offer only an analogy.
Comment [7] to Rule 1.10, written about the lateral-lawyer screen under paragraph (a)(2), warns that "even where screening mechanisms have been adopted, tribunals may consider additional factors in ruling upon motions to disqualify a lawyer from pending litigation."
Whether tribunals treat a nonlawyer's screen the same way is not something our research verified.
Rule compliance and the outcome of a disqualification fight are not the same question — which is where the last section of this page picks up.
What should you ask a staff candidate about prior matters?
Collect what a conflicts search runs on, not confidential detail.
At first substantive contact, ask for every firm, agency, court or legal department they have worked at, with dates; the practice areas they supported at each; and whatever matters, clients or adverse parties they are able to name.
Ask what they can share and take the answer at face value — pressing a staff candidate for client confidences is a bad start to the relationship.
Ask the direct-conflict questions too: any personal or financial interest in a party or an adverse party on a matter they supported — a relative, a stake, a former employer — and anything their previous firm told them they were barred from touching.
These answers cost the candidate nothing to give, and they get asked rather than searched for: the search you run matches the names it is given, and a relative or a former employer is a name only the candidate can supply.
Then feed the answers into the same search you run on every hire.
What comes back — clean, a hit against a current client of yours, a hit against a matter one of your lawyers touched at their old firm — is decision material, and the next section is what to do with a hit.
How to screen a non-lawyer hire
Run the check before the start date, not after.
The history you collected in the interviews goes through your conflicts system the way any hire's does, and you want the result in hand while you still have options — an offer not yet made, a start date not yet set.
(The rest of the process, from posting to pay, is the hiring a paralegal guide's job, not this page's.)
When a hit turns up, the model comment's expectation is the screen: such persons "ordinarily must be screened from any personal participation in the matter."
For staff, a screen is mostly access control — no staffing on the matter, no time entries against it, no access to its file, correspondence or document-management folder — plus a short note to the lawyers on the team naming who is off the matter and why.
Keep that note in the conflicts file, next to the search that triggered it.
One scope note before you borrow the attorney machinery: the formal screen the model rule builds for laterals — timely screening of the lawyer, the fee apportionment, the notice and certifications — is written around a screened lawyer.
Whether your state expects any of that when the screened person is a paralegal is not something our research verified, so if the hit is active litigation or a current client of the firm, put that specific fact pattern to your state bar's ethics counsel.
For what the full attorney-side screen involves, our guide to ethical screens walks through it step by step.
When disqualification still happens
Screening rather than imputation is the model rule's answer for nonlawyers — so when does a staff conflict still end up in front of a tribunal?
The verified record gives a shape, not a prediction.
Comment [7]'s caution, quoted above, is written about the lateral-lawyer screen under paragraph (a)(2): even where screening mechanisms have been adopted, tribunals may consider additional factors on a motion to disqualify a lawyer from pending litigation.
Read it as an analogy only — how tribunals weigh a nonlawyer's screen is not something our research verified.
And what Comment [4] screens against is the person's personal participation in the matter — so the failure mode is a screen that exists on paper but not in the access controls.
Which state decisions say what about nonlawyer conflicts is not something our research verified, so this page will not guess at outcomes in your state's courts.
The conclusion that survives is about process: run the search before the start date, disposition a hit while the offer is still negotiable, and document any screen in the same file as the search that triggered it — the cheapest time to learn a hire is conflicted is before they are on the payroll.
So the working answer to the title question: hire on a clean search; screen the hit you find; keep the person who cannot touch the matter away from its files; and put anything live — active litigation, a current client, a screen your state's rule may not allow — to your state bar's ethics counsel before the first day.
Employer information, not legal advice. This page describes the ABA's model rules as researched; your state's adopted version controls, and states differ. Confirm current requirements with your state bar's ethics counsel before you act on them.
The staff-hire conflicts file
- Firm history with dates: every firm, agency, court or legal department the candidate worked at — back to their first legal job, whatever the role
- Practice areas supported at each, plus the matters, clients or adverse parties they say they may name
- Direct-conflict answers: personal or financial ties to parties, and anything their previous firm told them they were barred from touching
- Searches run: which databases and client indexes, on which dates, by whom
- Hits and dispositions: screen, pass, or a referral to your state bar's ethics counsel — with a decision-maker named for each
- If screened: the note to the matter team naming who is off the matter, and the access restrictions that enforce it
Questions employers ask
What should I do if a conflict turns up after my new paralegal has already started?
Screen first, decide second: take the person off any personal participation in the matter — staffing, time entries, file access — while you work out the disposition, and put the fact pattern to your state bar's ethics counsel if the matter is active litigation or a current client.
Under the model text the conflict is not imputed to your lawyers, and Comment [4]'s screening expectation follows the conflicted person, not the hiring stage — so screen now, and work the disposition out alongside it.
Do temporary and agency paralegals need the same conflicts check?
Run the same history collection and search before their first assignment — the person is new to your matters either way.
What our research did not verify is how any state's rule treats agency or temporary staff for screening purposes, so if a placement will touch live matters, ask the agency for the person's matter history and confirm the screen expectations with your state bar's ethics counsel.
Can I hire a paralegal whose conflict is with a client my firm already represents?
First, locate where the conflict comes from.
If the candidate supported a matter at their previous firm for a party on the other side from your client, that is the former-firm pattern this page centers on — the search is how it gets caught, and the model comment's expectation is the screen.
If the candidate instead has a personal or financial tie to your client or to a party adverse to it, that is a different fact pattern: whether it is a conflict at all is not something our research verified, and the screen the model rule builds for laterals is not the mechanism for it, because that machinery is written for a former-client conflict from a prior firm.
How any state treats either pattern for nonlawyer staff is not something our research verified, so put the specific one to your state bar's ethics counsel before the offer — which is exactly why the check runs before the start date.
