The Circle of Imputation
Imputation of a conflict to the firm while lawyers are associated
The Circle of Imputation
Rule 1.10(a) imputes a conflict only to lawyers "associated in a firm," and those words mark the edge of the doctrine.1 Inside the circle, a prohibition that would bind one lawyer practicing alone binds every colleague. Outside it, the same conflict stays with the lawyer who carries it. The general rule showed what crosses the line: a Rule 1.7 or Rule 1.9 prohibition. This section asks who stands inside the line, because the answer decides whose clients, files, and fees one lawyer's history can disturb.
The circle has three edges that need care. The Rules define firm for themselves, and the definition reaches well past the private partnership, so a lawyer's workplace may sit inside the circle even when no one would call it a law firm. Government offices run on a separate track: conflicts involving lawyers in public service go to Rule 1.11, and the general imputation rule does not carry over. And paragraph (a) speaks of lawyers, which leaves a paralegal, a secretary, or a law clerk in a different position from a lawyer. Each edge gets a subsection, beginning with the definition, because the other two make sense only once the circle is drawn.
What Counts as a Firm
Rule 1.0(c) defines a firm as a lawyer or lawyers in a law partnership, professional corporation, sole proprietorship, or other association authorized to practice law, together with lawyers employed in a legal services organization or the legal department of a corporation or other organization.2 Comment 1 to Rule 1.10 calls the term broadly defined, and the consequence is that imputation reaches every lawyer within any such association or entity, not only those in a traditional office law firm.3 The first half of the definition lists the forms through which lawyers ordinarily offer services to the public and ends with a catch-all, so the name a group of lawyers chooses does not matter. The second half reaches lawyers who practice inside an institution and serve only that institution: a company's in-house counsel and the attorneys of a legal aid office. The same phrase about lawyers associated in a firm opens Rule 1.8(k), so the definition draws the circle there too.4
The breadth follows from what imputation protects. The whole firm owes the client loyalty, whichever lawyer is assigned to the file, and during the representation confidential information held by one lawyer is presumed to have been shared with every other.5 The conflicts rules aim at the risk of harm to clients, not at harm that has already occurred.6 Neither the duty nor the presumption depends on whether the lawyers are partners or owners. Salaried lawyers in a legal department can share files and information as readily as partners do, and the department's client is owed the same loyalty. A rule that reached only groups calling themselves law firms would leave that risk uncovered.
Legal form therefore does not settle whether two lawyers form one firm. The operative word in Rule 1.10(a) is associated,7 and the reasons for imputation point to a practical test: do the lawyers present themselves to clients and the public as one practice, and do they share client files and information? A department of employee-lawyers answers yes. Lawyers who merely share space answer no.
The answer turns on facts. Suppose the same two lawyers adopted a joint name, printed shared letterhead, and moved their files onto one server that both could open. They would then hold themselves out as one practice and pool what they know, and the likelier conclusion would reverse. A sole proprietor standing alone is already a firm, so a lone practitioner's conflict never reaches an outsider, and two separate sole proprietorships do not merge into one firm unless they begin to operate as one.
One group of lawyers sits outside this broad sweep. Government legal offices look like associations of lawyers, yet Rule 1.10(d) routes conflicts involving government lawyers to Rule 1.11, as the next subsection explains.8
Government Offices
Rule 1.10(d) is a routing provision: the disqualification of lawyers associated in a firm with former or current government lawyers is governed by Rule 1.11.10 As a result, the per se disqualification rule does not extend to government offices.11 The general imputation rule, and the lateral-hire screening exception in Rule 1.10(a)(2) taught in later subsections, do not decide whether a firm is disqualified by a lawyer who is or was in public service. The analysis opens with one diagnostic question: was the lawyer's other employer a government agency?
The separate track exists partly because the rule that imputes a conflict would otherwise punish public service. Comment 4 to Rule 1.11 says the special provisions for screening or waiver are necessary to prevent the disqualification rule from imposing too severe a deterrent against entering public service.12
Start with the lawyer who has left government for a private firm. Under Rule 1.11(b), when that lawyer is disqualified because of having participated personally and substantially in the matter while in public office, every other lawyer in the new firm is likewise disqualified.13 Rule 1.11(c) adds a second bar: the firm may not undertake or continue a representation adverse to a person about whom the lawyer obtained confidential government information, if that information could be used to the person's material disadvantage.14 The firm can avoid the Rule 1.11(b) result by meeting three conditions. The disqualified lawyer is timely screened from any participation in the matter, the lawyer is apportioned no part of the fee, and written notice is promptly given to the appropriate government agency so that it can ascertain compliance. The fee condition removes any financial stake that might tempt the lawyer past the screen. The agency must be told, but its consent is not required. The full operation of Rule 1.11 belongs to its own reading. Here the point is only that this screen is a feature of Rule 1.11.
The Iowa Supreme Court's decision in Sorci shows imputation following association. The court held that the imputed disqualification of the other attorneys at the Youth Law Center was lifted once the former assistant county attorney resigned as the center's executive director.15
The two lawyers have nearly identical histories with the same landlord. Only one fact changes the governing rule: whether the earlier employer was a government agency. In the first scene the notice goes to a public body that can check compliance, which is the function notice serves under Rule 1.11.
The other half of the problem concerns a lawyer who is currently in public service and is disqualified from a matter under Rule 1.11(d). That lawyer's disqualification is not automatically imputed to the other lawyers in the agency. A colleague can still be disqualified directly if the conflict is of a kind that office relationships or other influences would materially limit that colleague's own representation.16 Two routing errors recur on exams. One treats a government agency as a firm under Rule 1.10(a), so that a single lawyer's conflict binds every colleague in the office. The other applies the lateral screen of Rule 1.10(a)(2), with its notice to a former private client, to a private firm that has hired a former government lawyer, when Rule 1.11 governs and the notice runs to the agency.
Nonlawyer Conflicts
Rule 1.10(a) imputes the prohibitions of lawyers, so it has nothing to impute when the person with the conflict is not a lawyer. The text bars each lawyer associated in a firm from knowingly taking a representation that any one of them, practicing alone, would be prohibited from taking under Rule 1.7 or Rule 1.9.20 A paralegal, a secretary, or a law clerk is not a lawyer who can be barred from representing anyone. Comment 4 draws the consequence: if such a person is prohibited from involvement in a matter, the lawyers in the firm are not similarly disqualified.21 The comment treats a lawyer whose conflict arises from events before admission to the bar the same way. Work done for another firm as a law clerk during law school is the standard example, and that disqualification is not automatically extended to the firm's other lawyers.22
The limit follows from what the conflict rules regulate. Rules 1.7 and 1.9 impose duties of loyalty and confidentiality on lawyers, so a nonlawyer's earlier tie to the other side does not create the lawyer's prohibition that imputation exists to spread. Spreading it anyway would let a personnel decision disqualify an entire firm. One paralegal who once worked for the opposing side would remove every lawyer from the case, and the client would lose its counsel in the middle of a matter.
Withholding automatic disqualification leaves the confidentiality problem in place, and the comment addresses it directly. A nonlawyer who worked for the other side may know that client's confidences, and both that person and the firm have a legal duty to protect them. Comment 4 therefore says that such persons "ordinarily must be screened from any personal participation in the matter to avoid communication to others in the firm of confidential information that both the nonlawyers and the firm have a legal duty to protect."23 A screen, meaning internal measures that keep a person away from the matter and from the lawyers working on it, matches the actual risk. Among lawyers, the rule presumes colleagues share what they know. For a single nonlawyer the firm can interrupt that sharing, and the price is one person's absence from one matter.
This screen differs from the lateral-hire screening exception in Rule 1.10(a)(2), which later subsections teach. That exception relieves a firm of an imputed bar that already exists because a lateral lawyer is disqualified under Rule 1.9. A paralegal's conflict creates no imputed bar to relieve, so the screen here is simply a protective step to keep confidences from moving.
The prior work and the new matter are the same in both scenes. The only fact that moves the answer is whether the person who did the work was an admitted lawyer. An exam stem that describes a new hire's earlier work for the other side invites two opposite errors. One treats the paralegal's history as imputed to the firm's lawyers, as if Rule 1.10(a) reached every employee. The other concludes that because no disqualification follows, the firm has nothing left to do, which overlooks the duty to protect the former employer's client's confidences through a screen.
A lawyer's own history can fall on the nonlawyer side of the line. When the earlier work was done before admission to the bar, the person was not yet a lawyer, and the case is treated like the nonlawyer case: the firm's other lawyers are not automatically disqualified, and the person ordinarily must be screened.24 The hinge is the person's status when the events occurred.
