FINRA Rule 9141

FINRA Rule 9141(a): Pro Se Appearance

FINRA Rule 9141(a) confirms the fundamental right of any person to appear in a Code proceeding on their own behalf — the pro se right that is a bedrock feature of adversarial regulatory proceedings. A natural person who is a respondent in a disciplinary proceeding, a member firm whose principals choose to represent the firm directly, or any other party to any Code proceeding may elect to proceed without counsel or a representative.

The contact information obligation that attaches to a pro se appearance is the operational consequence of the choice to appear without representation. When a person first makes any filing or otherwise appears on their own behalf before an Adjudicator — whether by filing an answer to a complaint, requesting a hearing in an expedited proceeding, or appearing at a pre-hearing conference — they must file with the Adjudicator, or otherwise state on the record, a current address at which any notice or other written communication may be sent and a telephone number where they may be reached during business hours. The keep current obligation means the contact information is not a one-time registration but a continuing maintenance obligation throughout the proceeding — a pro se party who moves or changes telephone numbers must update the Adjudicator and all other parties promptly.

The rationale for requiring current contact information at the first pro se appearance mirrors the rationale for FINRA Rule 9135(d)'s email address registration requirement for OHO proceedings — effective service of all documents, scheduling of hearing dates, and communication of procedural developments all depend on reliable contact information being on file with the adjudicative body. A pro se respondent who fails to maintain current contact information cannot claim lack of notice when documents are properly served at the registered address.

The pro se appearance right is not unlimited. FINRA Rule 9141(b)'s representation rules and FINRA Rule 9150's exclusion authority create the boundary conditions within which pro se appearances operate. A person excluded from appearing in FINRA proceedings under FINRA Rule 9150 cannot proceed pro se any more than they can proceed through a representative — the exclusion applies to all modes of appearance.

FINRA Rule 9141(b): Representative Appearance and the Notice of Appearance

FINRA Rule 9141(b) governs appearance in a representative capacity — the most common mode of appearance in FINRA disciplinary proceedings, where respondents are typically represented by securities defense attorneys. The rule establishes an exclusive framework: a person shall not be represented before an Adjudicator except as provided in FINRA Rule 9141(b). This exclusivity prevents the use of non-qualifying representatives — unlicensed practitioners, foreign attorneys, or unauthorized persons — to circumvent the professional standards that the rule imposes.

Subject to the prohibitions of FINRA Rules 9150 and 9280, three categories of persons are authorized to appear in a representative capacity. The broadest category — and the one most commonly used in disciplinary proceedings — is attorneys at law admitted to practice before the highest court of any state, the District of Columbia, or any U.S. commonwealth, territory, or possession. This standard encompasses any licensed U.S. attorney in good standing with any state bar — a securities defense attorney admitted in Maryland can represent a respondent in a FINRA OHO proceeding regardless of where the proceeding is held or where the respondent is located. The standard does not require admission in the specific state where OHO is located or where the hearing will take place — admission to any U.S. bar suffices.

The second category — a member of a partnership representing the partnership — accommodates the specific entity structure of partnership-organized broker-dealers. A general partner of a firm organized as a partnership may represent the firm in a Code proceeding without being an attorney, provided they are a bona fide member of the partnership rather than a nominal partner.

The third category — a bona fide officer of a corporation, trust, or association representing that entity — similarly accommodates corporate broker-dealers whose officers are not attorneys. A registered principal who serves as a bona fide officer of a corporate member firm may represent the firm in a Code proceeding. The bona fide qualifier prevents nominal officer appointments made specifically to enable non-attorney representation — the officer must genuinely occupy the officer role as a matter of corporate governance rather than having been appointed solely for litigation purposes.

The cross-reference to FINRA Rule 9150 — Exclusion from Rule 9000 Series Proceeding — ensures that attorneys or representatives who have been excluded from FINRA proceedings under that rule's authority cannot use FINRA Rule 9141(b)'s representative authority to circumvent their exclusion. The cross-reference to FINRA Rule 9280 — Disqualification of Counsel — provides the mechanism for Adjudicators to address conflicts of interest and other grounds for disqualifying specific counsel from a proceeding.

The Notice of Appearance requirement is the formal mechanism through which representative status is established in the proceeding. When a person first makes any filing or otherwise appears in a representative capacity before an Adjudicator — whether by filing the answer to the complaint, submitting a motion, or appearing at a pre-hearing conference — that person must file a Notice of Appearance with the Adjudicator and keep it current throughout the proceeding. The Notice of Appearance is a written document that states the name of the proceeding, the representative's name, business address, and telephone number, and the name and address of the person or persons being represented. A representative who appears without having filed a Notice of Appearance is acting outside the requirements of FINRA Rule 9141(b) — any papers filed by a representative who has not previously appeared constitute a deemed Notice of Appearance requiring the representative to promptly bring their filing into compliance with FINRA Rule 9141(b)'s formal requirements.

The power of attorney provision in FINRA Rule 9141(b)'s final sentence — that any individual appearing in a representative capacity may be required to file a power of attorney showing their authority to act — applies primarily to non-attorney representatives such as partnership members or corporate officers. An attorney appearing for a client is presumed to have authority through the attorney-client relationship evidenced by their retention; a non-attorney representative's authority to act on behalf of an entity may require documentation through a formal authorization instrument.

The Notice of Appearance's practical significance throughout the Code is substantial. FINRA Rules 9132 and 9133 both provide that once counsel has filed a Notice of Appearance, all subsequent documents are served on counsel rather than directly on the party — making the Notice of Appearance the mechanism that activates the counsel service rule for the entire proceeding. FINRA Rule 9131 permits the Department of Enforcement to serve the complaint on counsel when counsel agrees — an agreement that presupposes the existence of retained counsel who will file a Notice of Appearance at the proceeding's outset. FINRA Rule 9137's signature requirement applies to counsel who has filed a Notice of Appearance. Every significant procedural obligation downstream from the commencement of a proceeding references the notice of appearance framework that FINRA Rule 9141(b) establishes.

FINRA Rule 9141(c): The One-Year Revolving Door Restriction

FINRA Rule 9141(c) prohibits any former officer of FINRA from making an appearance before an Adjudicator on behalf of any other person under the Rule 9000 series within a period of one year immediately after termination of their employment with FINRA. This cooling-off period — one of three FINRA Revolving Door restrictions — addresses the specific concern that former FINRA officers who are attorneys might leverage their former regulatory positions, their relationships with current FINRA Adjudicators and staff, and their knowledge of FINRA's internal investigative and adjudicative processes to provide an unfair advantage to clients in FINRA disciplinary proceedings immediately following their departure from FINRA.

The restriction applies specifically to former officers — not to all former FINRA employees. FINRA's internal organizational structure designates certain senior positions as officer-level roles — the Chief Hearing Officer, the Head of Enforcement, senior vice presidents with regulatory authority, and comparable positions. Non-officer employees who leave FINRA and become securities defense attorneys are not subject to FINRA Rule 9141(c)'s appearance restriction, though they remain subject to the broader confidentiality obligations in FINRA Rule 9910 and applicable conflict of interest restrictions.

The one-year period runs from the date of termination of FINRA employment — not from any earlier date such as the date of commencement of job negotiations with a defense firm. A former FINRA officer who terminates on January 1 is prohibited from appearing before any FINRA Adjudicator on behalf of any client until January 2 of the following year. The restriction applies to all appearances in all types of Code proceedings — disciplinary, expedited, eligibility, cease and desist — not merely to cases that the former officer personally worked on during their FINRA tenure.

The companion restriction in FINRA Rule 9242(b) prohibits former FINRA officers from providing expert testimony on behalf of another person in a FINRA disciplinary proceeding during the same one-year cooling-off period, addressing the specific concern that former officers might circumvent the appearance restriction by appearing as expert witnesses rather than as counsel of record. FINRA Rule 9910's broader restrictions apply to all former FINRA officers and employees — prohibiting communications to or appearances before FINRA Governors or employees with the intent to influence official FINRA action for a period following departure, in addition to permanent restrictions on subject matter conflicts involving specific matters handled during FINRA employment.

The Notice of Appearance in Current OHO Practice

Regulatory Notice 25-10 — announcing the SR-FINRA-2025-013 amendments effective October 7, 2025 — specifically noted that FINRA Rule 9141's requirements apply when appearing before any Adjudicator as defined in FINRA Rule 9120(a), confirming that the Notice of Appearance requirement extends to all Code proceeding types and all Adjudicative bodies — OHO Hearing Officers and Panels, the NAC, Review Subcommittees, Extended Proceeding Committees, and Statutory Disqualification Committees. The OHO Notice of Complaint letter sent to respondents with each complaint now includes instructions on how to file the answer and other documents with OHO through the Portal, with FINRA Rule 9141's Notice of Appearance requirement explicitly referenced as part of the initial appearance process.

Connection to FINRA Rules 9150 and 9280

FINRA Rule 9150 — Exclusion from Rule 9000 Series Proceeding — grants Adjudicators authority to exclude attorneys or other authorized representatives from a proceeding for contemptuous conduct, willful violation of protective orders, or other specified conduct incompatible with orderly proceedings. Exclusion under FINRA Rule 9150 operates as a suspension of the appearance right established by FINRA Rule 9141(b) — a representative excluded under FINRA Rule 9150 loses their ability to appear under FINRA Rule 9141(b) in the proceeding that generated the exclusion order. The final sentence of FINRA Rule 9150 clarifies that excluding an attorney or representative from a FINRA proceeding does not preclude FINRA from initiating other proceedings against that person — the exclusion is a proceeding-specific remedy, not a permanent bar from FINRA proceedings generally.

FINRA Rule 9280 — Disqualification of Counsel — provides the mechanism for a party or the Adjudicator to raise and resolve conflicts of interest involving counsel representing a party in a Code proceeding. Where FINRA Rule 9141(b) establishes who may appear, FINRA Rule 9280 addresses when an otherwise-eligible attorney should be disqualified from a specific proceeding due to a conflict of interest — whether a current client conflict, a former client conflict, or an attorney-witness conflict arising from the attorney's personal knowledge of relevant facts.

Examination Relevance and Key Takeaways

FINRA Rule 9141 is tested on the Series 24 General Securities Principal examination in the context of the Code of Procedure's appearance and practice requirements, the Notice of Appearance framework, and the revolving door restrictions applicable to former FINRA officers. The rule's connection to the service framework of FINRA Rules 9131 through 9134 — through the counsel service provisions that activate upon filing of a Notice of Appearance — makes it a central rule in any examination question tracing the procedural consequences of retaining counsel in a disciplinary proceeding.

The key points to retain are these: FINRA Rule 9141 establishes three appearance frameworks — pro se appearance by any person with a current address and telephone number kept on file, representative appearance by qualifying attorneys and entity officers or partners with a Notice of Appearance on file, and the one-year revolving door restriction barring former FINRA officers from appearing before any FINRA Adjudicator on behalf of any other person in any Rule 9000 series proceeding; authorized representatives are licensed U.S. attorneys admitted before the highest court of any state or U.S. territory, members of partnerships representing the partnership, and bona fide officers of corporations, trusts, or associations representing those entities; representative appearance is conditioned on the prohibitions of FINRA Rule 9150 — Exclusion from Proceedings — and FINRA Rule 9280 — Disqualification of Counsel; a Notice of Appearance must be filed by the representative at or before their first filing or other appearance and must be kept current throughout the proceeding — stating the proceeding name, the representative's name, business address, and telephone number, and the name and address of the person or persons represented; filing of papers by a previously non-appearing representative constitutes a deemed Notice of Appearance requiring conforming documentation; filing of a Notice of Appearance activates the counsel service rule under FINRA Rules 9132 and 9133 — all subsequent documents are served on counsel rather than directly on the party; the one-year revolving door restriction in FINRA Rule 9141(c) was added by SR-FINRA-2011-032 effective July 2011 and applies to all former FINRA officers for one year following termination of employment, complemented by FINRA Rule 9242(b)'s restriction on expert testimony and FINRA Rule 9910's broader post-employment restrictions; and FINRA Rule 9141 was last amended by SR-FINRA-2011-032 effective July 8, 2011.
