When a law firm changes its name, must it immediately update all of its advertising, signs, and website domain to the new name?
NY State Bar Ethics Opinion 1095: Updating advertising after a firm name change
Short answer: A firm that changes its name by adding a partner has a reasonable time to update its existing advertising, with reasonableness judged by whether the old ads are misleading and the cost and ease of changing them; website domain names need not match the legal name, and large building signs that serve as branding are not advertising and need not be changed.

Plain-English summary
A firm changed its name from "A & B" to "A, B & C" by adding the name of C, an existing partner. Its existing television commercials and bus-shelter ads still used the old name, as did large signs on two sides of its office building and the firm's website domain name (¶¶ 1-2). It asked whether it had to change everything immediately (¶ 3).
The committee applied Rule 7.1(a)(1) (no false, deceptive, or misleading advertising), Rule 7.1(h) (ads must include the firm name whose services are offered), and Rule 7.5 (office signs and firm names) (¶ 4). On the television and bus-shelter ads, which are advertisements, the committee drew on N.Y. State 1030 (2014), where a firm that added a partner could keep using old letterhead and checks while stock depleted; it held a similar grace period applies, giving the firm a reasonable time to update the ads (¶¶ 6-7). What is reasonable depends on whether the old advertising is misleading (it generally is not, since firm names need not list every partner), and on the cost and ease of correction; for ads the firm cannot simply alter itself, a reasonable period will ordinarily be measured by the period covered in the advertising contract, for example the end of a 90-day bus-shelter run (¶¶ 8-11). The committee distinguished the case of a name partner leaving the firm, where continued use of the old name could mislead and require prompt correction (¶ 9).
On the large building signs, the committee relied on Comments [6] and [8] to Rule 7.1, which exclude marketing or branding materials whose primary purpose is general awareness from the definition of "advertisement." It concluded the large building signs are branding, not advertising, and need not be changed, while small office signs near the entrance, covered by Rule 7.5(a), must be updated within a reasonable time (¶ 12). On the domain name, Rule 7.5(e) and Comment [2] permit a firm to use its own name, initials, or a variation as a domain, so the firm could keep its old-name domain (¶ 13, citing N.Y. State 1003 (2014)).
In practice
Under the New York rules as they stood at the time of the opinion, the committee treated a name change that adds an existing partner as a low-risk situation: because firm names need not name every partner, the old ads are generally not misleading, so the firm gets a grace period rather than an immediate-correction duty. The opinion ties the length of that period to the practicalities, principally the advertising contract term for media the firm cannot change itself. It also sorts the firm's materials into three buckets: advertisements (grace period), small office signs (reasonable time), and branding such as large building signs and the website domain (no change required), and flags that a departing name partner would change the misleading analysis.
Common questions
Q: Does a firm have to pull its old-name TV and bus ads the moment it changes its name?
A: No. The opinion concludes the firm has a reasonable time to update them, ordinarily measured by the period covered in the advertising contract, because adding an existing partner's name does not make the old ads misleading (¶¶ 7, 11).
Q: Must the firm's website domain name match the new legal name?
A: No. The opinion concludes under Rule 7.5(e) and its comments that a firm may use its name, initials, or a variation as a domain, so it may keep the old-name domain (¶ 13).
Q: Do the large building signs with the old name have to come down?
A: No. The opinion concludes large building signs are branding for general awareness, not advertisements under Rule 7.1, so they need not be changed; small office signs near the entrance must be updated within a reasonable time (¶ 12).
Background and rules framework
The opinion interprets New York Rules of Professional Conduct 7.1(a) and (h) (no misleading advertising; firm-name disclosure) and 7.5(a), (b), and (e) (office signs, misleading firm names, and domain names), corresponding to ABA Model Rules 7.1 and 7.5. Comments [6] and [8] to Rule 7.1 supply the line between advertisements and branding/marketing materials, and Comment [2] to Rule 7.5 supplies the latitude for domain names.
