FINRA Rule 9521

The definitions provision establishes precise meanings for Application, disqualified member, disqualified person, and sponsoring member — the four terms whose precise legal significance must be understood to apply every subsequent rule in the 9520 series correctly.

FINRA Rule 9521 sits within the 9520 Eligibility Proceedings series of the 9500 Other Proceedings section of the 9000 Code of Procedure. It was adopted in its original form by SR-NASD-97-28 effective August 7, 1997, amended by SR-NASD-99-76 effective September 11, 2000, amended by SR-FINRA-2008-021 effective December 15, 2008, and most recently amended by SR-FINRA-2019-009 effective May 8, 2019 — a broadly scoped amendment that made various updates across the Rule 9520 series. Two selected notices are associated — 00-56 and 08-57.

FINRA Rule 9521(a): The Two-Category Purpose Statement

FINRA Rule 9521(a) establishes the purpose of the Rule 9520 series through a dual-category framework that captures the complete scope of eligibility proceedings.

The first category — procedures for a person to become or remain associated with a member notwithstanding the existence of a statutory disqualification — is the category that most practitioners think of when they refer to statutory disqualification proceedings. 

A registered representative who has a prior felony conviction, a prior bar from another SRO, or another event constituting a statutory disqualification under Exchange Act Section 3(a)(39) is presumptively ineligible to associate with a FINRA member. 

The Rule 9520 series provides the mechanism through which that person, with the support of a sponsoring member, may apply for FINRA's permission to associate or continue to associate notwithstanding the disqualifying event. The outcome of this application process — whether FINRA grants or denies the person's association — has profound consequences for the individual's ability to remain in the securities industry.

The statutory disqualification definition in Article III, Section 4 of the FINRA By-Laws incorporates by reference the Exchange Act Section 3(a)(39) definition of statutory disqualification — a comprehensive list encompassing criminal convictions, civil injunctions, regulatory orders, and other specified events. The breadth of this definition means that a surprisingly wide range of past events may trigger statutory disqualification status, making the Rule 9520 series procedurally important not only for persons with serious criminal or regulatory histories but also for persons with certain less serious past events who might not realize they are subject to statutory disqualification.

The second category — procedures for a current member or associated person to obtain relief from the eligibility or qualification requirements of the FINRA By-Laws and FINRA rules — encompasses a broader range of situations where a person or firm that is currently associated with or a member of FINRA faces eligibility or qualification challenges that require FINRA's formal permission to address. This might include situations where a member firm's ownership structure has changed in a way that implicates FINRA's membership eligibility standards, or where an associated person has become subject to a new disqualifying event and the firm seeks to retain them through a supervised continuation arrangement.

The phrase such actions hereinafter are referred to as eligibility proceedings consolidates both categories under a single definitional term — every proceeding under the Rule 9520 series is an eligibility proceeding, whether it addresses a person seeking to associate despite a statutory disqualification or a current member or associated person seeking relief from qualification requirements.

FINRA Rule 9521(b)(1): Application

The Application definition — FINRA's Form MC-400 for individuals or Form MC-400A for members, filed with the Department of Registration and Disclosure — is the most operationally critical defined term in FINRA Rule 9521(b). Every eligibility proceeding that requires formal FINRA approval begins with the submission of the appropriate Form MC-400 or MC-400A to FINRA's RAD Department.

Form MC-400 — the individual application — is used when a disqualified person is seeking to become or remain associated with a specific sponsoring member firm. The form requires comprehensive disclosure of the disqualifying event, detailed information about the nature and circumstances of the disqualification, information about the proposed association, and the sponsoring member's supervisory plan for the disqualified person. The sponsoring member certifies in the application that it has assessed the disqualified person's fitness and that the supervisory plan is adequate to protect customers and the firm from the risks associated with the disqualifying event.

Form MC-400A — the member application — is used when a member firm itself is subject to a disqualification or eligibility concern and seeks relief. This category arises less frequently than individual disqualification applications but applies when a firm's ownership or control structure changes in ways that create statutory disqualification issues at the firm level.

The filing with RAD is the administrative initiation of the eligibility proceeding — the moment the application is submitted to RAD begins the formal review process that FINRA Rule 9522 governs. RAD's receipt of the application triggers the Department of Member Regulation's review process and ultimately the eligibility proceeding's formal adjudicative track if DMR cannot approve the matter without a formal hearing.

FINRA Rule 9521(b)(2): Disqualified Member

The disqualified member definition — a broker, dealer, municipal securities broker or dealer, government securities broker or dealer, or member that is or becomes subject to a disqualification or is otherwise ineligible for membership under Article III, Section 3 of the FINRA By-Laws — establishes which entities may be subjects of the member-application track of the Rule 9520 series. The breadth of this definition encompasses all categories of FINRA member entities — broker-dealers, municipal securities professionals, and government securities professionals — confirming that the Rule 9520 series applies across all member types rather than being limited to traditional broker-dealers.

The or becomes formulation is operationally significant — it encompasses not only firms that are subject to a disqualification at the time of their membership application but also firms that become subject to a disqualification after they are already FINRA members. A firm that acquires a disqualified person in a manner that creates a firm-level eligibility concern, or that itself becomes subject to a disqualifying regulatory action while already a FINRA member, may need to initiate a Rule 9520 proceeding to address the newly arising disqualification.

FINRA Rule 9521(b)(3): Disqualified Person

The disqualified person definition — an associated person or person seeking to become an associated person who is or becomes subject to a disqualification or is otherwise ineligible for association under Article III, Section 3 of the FINRA By-Laws — is the individual-level counterpart to the disqualified member definition. The definition encompasses both currently associated persons who become subject to a disqualification during their association with a FINRA member, and persons who are not yet associated with a FINRA member but who seek to become associated despite an existing disqualification.

The or becomes formulation again captures the post-association disqualification scenario — an associated person who is convicted of a felony during their career, who is barred by another SRO, or who becomes subject to any other statutory disqualifying event while associated with a FINRA member has become a disqualified person who requires eligibility proceeding approval to continue their association. The sponsoring member must file a Form MC-400 on behalf of such a person if it wishes to retain them in their associated capacity.

FINRA Rule 9521(b)(4): Sponsoring Member

The sponsoring member definition — the member or applicant for membership pursuant to FINRA Rule 1013 that is sponsoring the association or continued association of a disqualified person to be admitted, readmitted, or permitted to continue in association — defines the firm-side actor in every individual disqualification application. The sponsoring member is the entity that vouches for the disqualified person's fitness, commits to implementing the supervisory plan, and accepts responsibility for the oversight of the disqualified person's activities if FINRA approves the association.

The or applicant for membership pursuant to FINRA Rule 1013 component addresses the scenario where a person who is subject to a statutory disqualification is involved with a new firm that is applying for FINRA membership — both the new firm's membership application and the disqualified person's association application proceed concurrently through the Rule 9520 series and FINRA Rule 1013 processes respectively.

The three-pronged scope — to be admitted, readmitted, or permitted to continue in association — captures every temporal scenario in which a disqualified person might seek approval. Admitted covers new associations. Readmitted covers returning to association after a period of absence or suspension. Permitted to continue covers ongoing associations where the disqualification arose after the initial association was established.

The Statutory Disqualification Framework: Exchange Act Section 3(a)(39)

The definitions in FINRA Rule 9521(b) draw their significance from the statutory disqualification framework of Exchange Act Section 3(a)(39), which defines the events that trigger disqualification status under the federal securities laws. Congress designed this framework to prevent persons and entities with serious regulatory and criminal histories from operating in the securities industry — but recognized that a categorical permanent bar would be too inflexible, and therefore built in the eligibility proceeding mechanism through which FINRA can exercise case-by-case judgment about whether a specific disqualified person's association with a supervised firm is consistent with investor protection.

This case-by-case judgment framework is the substantive core of the Rule 9520 series — FINRA assesses each application based on the nature and seriousness of the disqualification, the time elapsed since the disqualifying event, the person's conduct since the event, the quality of the sponsoring member's supervisory plan, and the potential risk to investors and market integrity of approving the association. FINRA Rule 9521's definitional framework provides the vocabulary that subsequent rules in the series use to describe the actors in this assessment process.

Connection to FINRA Rules 9110, 9120, 9522, and the By-Laws

FINRA Rule 9521 connects to FINRA Rule 9110(a) — whose universal applicability principle makes the Rule 9100 General Provisions the default procedural framework for all Rule 9520 eligibility proceedings. It connects to FINRA Rule 9120 — whose Party definition in paragraph (y)(2) specifically addresses eligibility proceedings under the Rule 9520 series, confirming that the Department of Enforcement and the member filing an application are the parties in these proceedings. It connects to FINRA Rule 9522 — which uses all four defined terms to describe the initiation of eligibility proceedings and the DMR consideration process. And it connects to FINRA's By-Laws — specifically Article III, Sections 3 and 4 — which establish the eligibility and qualification requirements and the statutory disqualification definition that FINRA Rule 9521's purpose statement and definitions reference.

Examination Relevance and Key Takeaways

FINRA Rule 9521 is tested on the Series 24 General Securities Principal examination as the purpose and definitions rule for the Rule 9520 Eligibility Proceedings series — the foundational provision that establishes what eligibility proceedings are and who the key actors are.

The key points to retain are these: FINRA Rule 9521 establishes two categories of eligibility proceedings — procedures for a disqualified person to become or remain associated with a member despite a statutory disqualification under Article III, Section 4 of the FINRA By-Laws, and procedures for a current member or associated person to obtain relief from eligibility or qualification requirements of the FINRA By-Laws and FINRA rules; all such proceedings are collectively called eligibility proceedings; the Application is FINRA Form MC-400 for individuals or Form MC-400A for members filed with RAD; a disqualified member is a broker, dealer, or FINRA member that is or becomes subject to a disqualification or is otherwise ineligible for membership under Article III, Section 3 of the FINRA By-Laws; a disqualified person is an associated person or person seeking to become associated who is or becomes subject to a disqualification or is otherwise ineligible for association under Article III, Section 3; a sponsoring member is the member or membership applicant that sponsors the association or continued association of a disqualified person; the statutory disqualification framework derives from Exchange Act Section 3(a)(39) and encompasses criminal convictions, regulatory orders, SRO bars and suspensions, and other specified disqualifying events; and the rule was last amended by SR-FINRA-2019-009 effective May 8, 2019.
