When a law firm only knows an adverse party by a street name, does its conflict check have to go beyond its written engagement records?
NY State Bar Ethics Opinion 1085: Conflict checks for parties known only by street name
Short answer: When a firm has reason to believe it may have represented a materially adverse party it knows only by a street name, an effective conflict check may require going beyond the firm's written records to the memory of its lawyers; and obtaining a party's legal name later in a representation can make a new check advisable, though the conflict-checking rule does not require one.

Plain-English summary
The inquirer was a law student practicing under supervision in a law school clinic seeking post-conviction relief for a client who said he was a victim of human trafficking. The clinic had gathered information on the alleged traffickers, who are potentially adverse parties, but knew them only by their "street names" and general areas of residence, not their legal names (¶¶ 1-3).
The committee located the clinic's obligation in Rule 1.10(e), which imposes two affirmative conflict-detection requirements on a "law firm" (a term that includes a qualified legal-assistance organization, so the clinic counts): the firm must make a written record of its engagements, and it must maintain a system that checks proposed engagements against current and previous ones upon four triggering events (¶¶ 6-10). A conflict-checking system "must be adequate to detect conflicts that will or reasonably may arise," and may need to "supplement written information with recourse to the memory of the firm's lawyers" (¶¶ 10-11, quoting Rule 1.10 Cmts. [9], [9B]).
On the check before accepting a matter, the opinion concludes that whether the firm must go beyond its written records depends on the circumstances. Firms are "not routinely required to go beyond checking the written records," but where a lawyer is aware of facts raising a substantial prospect that a current or prior engagement involved a materially adverse party, an effective system requires reasonable efforts to contact the lawyers and students involved to ask about street names (¶¶ 13-15). On continuing obligations after accepting the matter, the committee found that acquiring new information mid-representation, including learning the traffickers' legal names or naming them in motion papers, is not one of the four triggering events, so no fresh check is mandated (¶¶ 16-18). It remains advisable, however, because the individual lawyer is independently responsible for conflicts the system does not catch (¶ 19, citing Rule 1.10 Cmt. [9A] and Rule 5.1(a)).
In practice
Under the New York rules as they stood at the time of the opinion, the committee held that a firm's duty to check against its written records is the baseline, and the check must reach beyond those records to lawyers' memory only when the firm has reason to believe it may have represented an adverse party it cannot fully identify from the written file. The opinion also distinguishes the firm's system-level duty under Rule 1.10(e) from the individual lawyer's personal duty to avoid conflicts under Rules 1.7 and 1.9: a new check after learning a party's legal name is not required by the conflict-checking rule but may help the assigned lawyer meet that personal duty. The committee expressly declined to decide whether Rule 1.10(e) requires firms to record informal identifiers such as street names alongside legal names (¶ 20).
Common questions
Q: Does a New York firm always have to call its lawyers to check for conflicts, or is the written database enough?
A: The database is the baseline. The opinion concludes a firm is not routinely required to go beyond its written records, but must make reasonable efforts to consult the lawyers and staff involved in prior engagements when it is aware of facts raising a substantial prospect that those engagements involved a materially adverse party it cannot identify from the written file (¶ 15).
Q: If a lawyer later learns the legal name of an adverse party mid-case, does Rule 1.10(e) require a new conflict check?
A: No. The opinion concludes that acquiring new information during a representation is not one of the four events that trigger the conflict-checking requirement, and naming an alleged trafficker in motion papers does not make that person a party (¶¶ 17-18). A fresh check may still be advisable to help the lawyer meet the personal conflict duty under Rules 1.7 and 1.9 (¶ 19).
Q: Does a law school clinic count as a "law firm" for conflict-checking purposes?
A: Yes. The opinion applies Rule 1.0(h), which defines "law firm" to include lawyers employed in a qualified legal-assistance organization, and cites N.Y. State 794 (2006) treating a clinic with shared space and files as a firm (¶ 6).
Background and rules framework
The opinion interprets New York Rule of Professional Conduct 1.10(e) and (g) (the law firm's conflict-checking system) together with the underlying conflict prohibitions of Rule 1.7(a) (current-client and personal-interest conflicts) and Rule 1.9(a) (duties to former clients), all corresponding to ABA Model Rules 1.7, 1.9, and 1.10. Rule 1.0(h) supplies the definition of "law firm," and Rule 5.1(a) supplies the firm's duty to make reasonable efforts to ensure its lawyers conform to the Rules. The committee draws the substance of the adequacy standard from Comments [9], [9A], [9B], and [9C] to Rule 1.10.
