Why adviser law matters on Series 66
The Series 66 law section covers 45% of the scored exam. The NASAA study guide includes regulation of investment advisers and IARs, broker-dealers and agents, securities and issuers, administrative remedies, communication with clients, and ethical or fiduciary obligations. Candidates should study how the rules work in a scenario, not just memorize statute names.
The principal source families include the Investment Advisers Act of 1940, Securities Act of 1933, Securities Exchange Act of 1934, SEC rules, FINRA rules, the Uniform Securities Act of 1956 as amended by NASAA, NASAA model rules and statements of policy, and the Uniform Prudent Investor Act. For Series 66, the specified Uniform Securities Act is the NASAA-amended 1956 version, not the Uniform Securities Act of 2002. Candidates are responsible for the concepts identified in the guide, not every sentence in every source.
Start by identifying the person and capacity
An investment adviser is generally a person or firm that, for compensation, engages in the business of advising others about securities, subject to the applicable statutory definition and exclusions. An investment adviser representative is an individual associated with an adviser who provides advice, manages accounts or portfolios, solicits, offers, or negotiates for advisory services, subject to the applicable definition. The adviser is the entity or person providing advisory services; the IAR is the associated individual performing covered functions.
A broker-dealer is in the business of effecting securities transactions for others or for its own account, subject to statutory definitions and exclusions. An agent is an individual representing a broker-dealer or issuer in securities transactions, with the exact definition and exclusions governed by the applicable law. One person may have more than one role, but the capacity in which the person acts matters for a question.
Example: A registered advisory firm charges an ongoing fee for portfolio recommendations. Its employee who advises clients may be an IAR. If the firm also operates a broker-dealer affiliate and the employee executes securities trades in that capacity, the employee can have separate obligations as an agent. Do not treat 'financial adviser' as a single legal category that determines every requirement.
State-registered advisers and federal covered advisers
The outline distinguishes state-registered investment advisers from federal covered advisers. A federal covered adviser registers with the SEC under the federal framework, while states can retain certain authority such as notice filing and fees. State-registered advisers register with the relevant state or states. Questions may ask which regulator receives a registration or notice filing, whether the adviser qualifies for an exemption, or how the representative's registration is treated.
Do not collapse the firm and the individual. A federal covered adviser's status does not automatically answer whether each IAR must register with a state. The representative's location, role, and applicable state rules can matter. Likewise, a state adviser exemption does not necessarily remove antifraud duties or the need to analyze the individual's status.
Study adviser registration as a sequence: identify the definition, determine whether SEC or state jurisdiction applies, assess the relevant exemption or covered status, identify required filings or notice filings, and then consider post-registration responsibilities. Form ADV is central to adviser disclosure and registration information; Form U4 is associated with individual registration. A form filing is not the same as the regulator's final registration status.
Example: A firm is federally covered and offers services in State A, while its IAR has a place of business in State B. The question may ask about the firm's notice filing in State A or the individual's registration in State B. Those are separate issues. Identify which name appears in the final question before choosing a rule.
Advisory agreements, fees, and disclosures
An advisory relationship should clearly describe services, fees, how fees are calculated, payment, termination, and other required terms. The Series 66 guide identifies advisory contracts and disclosure requirements. Learn how compensation can create conflicts, including commissions, referral payments, performance fees, soft-dollar arrangements, political contributions, or incentives tied to a product or transaction.
A conflict is not solved merely because it is mentioned somewhere in a document. The adviser must address the conflict under applicable obligations and provide material information in a manner the client can understand. A recommendation still must fit the client's circumstances. For example, an adviser who receives a referral payment for recommending a private fund must consider both the incentive and whether the product's liquidity, fees, and risks fit the client.
Client communications include brochures, performance reports, websites, emails, social media, and conversations. A technically accurate statement can mislead through omission or context. A hypothetical return should not be presented as an actual result. A performance guarantee can be prohibited or misleading. A good exam analysis asks what a reasonable client would understand from the entire communication.
Fiduciary duties and client-centered advice
An adviser-client relationship involves fiduciary obligations. Candidates should understand duties of care and loyalty, disclosure, conflict management, prudent process, and the importance of acting for the client's benefit under the applicable standard. A client signature does not make every recommendation or practice proper. Disclosure of a conflict is important, but it does not eliminate the need to manage it.
Example: A client needs $30,000 for a home purchase in two years. An adviser recommends a high-yield private fund with limited redemptions and receives a referral fee. A complete analysis addresses the client's short horizon and liquidity need, the fund's valuation, leverage, expenses, and risk, the adviser's compensation conflict, and reasonable alternatives. A distractor that says 'disclose the referral and invest' does not resolve the suitability and liquidity issues.
Fiduciary analysis should be tied to the service and facts, rather than applied as a label. If the question asks whether the adviser had authority to trade, examine the account agreement and scope of discretion. If it asks whether the investment fits, analyze the client and product. If it asks whether a conflict was disclosed, identify the incentive and how it was communicated.
Custody, discretion, and client assets
Custody involves possession of client assets or authority that gives the adviser access to funds or securities under applicable rules. Discretion means authority to decide transactions without securing client approval for each trade. Custody and discretion are related but not identical. An adviser may have discretionary trading authority without physically holding assets, and specific trade authorization is not broad discretion.
Example: A client instructs an adviser to buy 100 shares of ABC. The adviser buys 100 shares of XYZ instead because it seems better. The instruction authorized a named trade, not a substitute. A later explanation does not necessarily supply the missing authority. Another example: the client signs a limited authorization allowing the adviser to select timing and security within a stated mandate. Analyze the scope rather than assume unlimited control.
Custody rules may require qualified custody, statements, surprise examinations, audits, or other safeguards depending on the facts and applicable rule. The exam expects candidates to recognize custody conditions and obligations, not to infer that every recordkeeping issue is custody. Read whether the adviser possesses assets, can withdraw funds, or has a relationship with a custodian.
Records, supervision, and cybersecurity
Advisers and broker-dealers maintain required books and records, supervise associated persons, and operate compliance programs. The outline includes Form ADV, Form BD, Form U4, recordkeeping, registration maintenance, written policies, business continuity, cybersecurity, privacy, and data protection. The precise duties depend on the actor and governing rule, but records should support communications, transactions, fees, and the advisory relationship.
A business message sent from a personal email or device does not stop being a business record simply because of the device. A representative should follow firm policies for approved communications and retention. A cybersecurity incident can implicate client privacy, business continuity, notification, and safeguarding duties. A candidate should not assume that a small firm is exempt from having a compliance process.
Broker-dealer and securities-law overlaps
The combined exam covers broker-dealer and agent regulation as well as adviser law. It also tests securities, issuers, offerings, exemptions, state and federal registration, administrator powers, remedies, and antifraud authority. Some facts concern a security's status or an offer; others concern the person effecting a transaction. Identify the issue before selecting a rule.
For an offering question, ask whether the instrument is a security, whether there is an offer or sale, whether the security or transaction is exempt, and what filing or registration consequence follows. For a person-registration question, identify the actor, capacity, and any exclusion. Exempt securities, exempt transactions, and exempt persons are different concepts; one does not automatically establish the others.
A repeatable law-question framework
- Name the actor: firm, adviser, IAR, broker-dealer, agent, issuer, or client.
- Name the capacity and activity: advice, solicitation, recommendation, execution, custody, advertising, or offering.
- Identify jurisdiction and regulator: federal, state, or both, and whether the adviser is covered or state registered.
- Find the trigger: compensation, place of business, client relationship, transaction, possession of assets, or control.
- Test the relevant exemption and its conditions; do not assume an exemption covers every actor or duty.
- Answer the exact prompt: registration, disclosure, authorization, client fit, remedies, or prohibited conduct.
This sequence is especially helpful when the question is worded generally, such as 'under the Uniform Securities Act' or 'under the Advisers Act.' NASAA notes that a prompt may test a statute, SEC rule, or NASAA model rule without naming it. Learn the enumerated concepts and recognize them from the behavior described.
Study method for adviser law
Build a two-page comparison chart. The first page compares adviser, IAR, broker-dealer, and agent by definition, registration, regulator, forms, supervision, and common exceptions. The second maps fiduciary issues: compensation, disclosure, contract, custody, discretion, records, communication, and prohibited conduct. Keep examples short and specific enough to reveal the tested distinction.
After each missed question, change one fact and solve again. Change a federal covered adviser to a state-registered adviser, move the representative's place of business, remove the referral payment, or replace discretionary authority with a specific client instruction. If the answer does not change when a legally controlling fact changes, revisit the rule.
Use mixed questions after learning a topic. A chapter quiz signals what rule is being tested; a mixed set requires you to recognize it. Include product and recommendation questions too because adviser law often appears inside a client scenario. Explain why the wrong choices fail, especially when they apply a correct principle to the wrong actor.
