FINRA Series 7 / 63 / 65 Prohibited Practices Under State Law
Last updated: May 2, 2026
Prohibited Practices Under State Law questions are one of the highest-leverage areas to study for the FINRA Series 7 / 63 / 65. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.
The rule
Under the Uniform Securities Act (USA) §501–§502 and the NASAA Statements of Policy on Dishonest and Unethical Business Practices, it is unlawful for any person — in connection with the offer, sale, or purchase of a security — to employ a device to defraud, make an untrue statement of material fact, omit a material fact, or engage in any act, practice, or course of business that operates as a fraud or deceit. The Administrator may also discipline agents and investment adviser representatives for non-fraudulent but dishonest or unethical conduct, including unauthorized trading, churning, commingling, guaranteeing against loss, selling away, and borrowing from or lending to customers. Liability under §501 attaches whether the misstatement was intentional or merely negligent, and applies to securities transactions even when the security itself is exempt from registration.
Elements breakdown
Fraud in the Offer or Sale (USA §501)
Antifraud provision reaching any device, scheme, untrue statement, omission, or course of business that operates as a fraud in connection with a security transaction.
- Connected to offer, sale, or purchase
- Material misstatement or omission
- Scheme or course of business defrauds
- Applies to exempt and non-exempt securities
- Scienter not always required
Prohibited Sales Practices by Agents
Agent-level conduct the Administrator treats as dishonest or unethical, even absent classic fraud.
- Unauthorized trading in customer accounts
- Churning to generate commissions
- Selling away from the broker-dealer
- Borrowing from or lending to customers
- Sharing in profits or losses without approval
- Guaranteeing the customer against loss
- Front-running or trading ahead
- Backdating order tickets or records
Common examples:
- Agent buys 500 shares without prior authorization
- Agent privately sells a real-estate LP outside the firm
Prohibited Practices by Investment Advisers
Conduct violating fiduciary duty under USA §502 and NASAA Model Rule on Unethical Practices of IAs and IARs.
- Undisclosed principal or agency cross trades
- Failure to disclose material conflicts
- Performance-fee arrangements outside permitted exceptions
- Custody without required safeguards
- Misleading advertising or testimonials in violation of rules
- Loaning to or borrowing from a non-institutional client
Misrepresentation and Omission
Communicating untrue or incomplete information about a security, issuer, registration status, or the agent's own qualifications.
- False claim of registration or approval
- Implying Administrator endorsement
- Misstating yield, risk, or guarantees
- Omitting facts material to the decision
- Predicting specific future performance
Market and Account Manipulation
Conduct that distorts prices, volume, or the integrity of a customer account.
- Matched orders and wash trades
- Marking the close
- Spreading false rumors to move price
- Excessive trading given the customer's profile
- Discretion exercised without prior written authority
Common patterns and traps
The Exempt-Security Escape Hatch
A wrong choice argues that because the security or transaction was exempt from registration, the antifraud provisions do not reach the conduct. This conflates registration exemptions with conduct rules. USA §501 expressly applies to all securities and all transactions, including those that are otherwise exempt under §401–§402.
A choice saying 'no violation occurred because U.S. Treasury securities are exempt' or 'the private placement was exempt, so the antifraud rule does not apply.'
Verbal-Discretion Trap
The fact pattern describes a customer giving oral permission to 'use your judgment,' and a wrong answer treats that as sufficient. Discretion over price and time alone (not asset, action, or amount) does not require written authority, but full discretion requires prior written authorization and firm acceptance of the account as discretionary before any discretionary trade is placed.
A choice that approves the agent's conduct because 'the client verbally agreed to let the agent decide.'
Profit-Means-No-Harm Fallacy
A wrong choice excuses the agent because the trades were profitable or the customer 'didn't complain.' Prohibited practices are evaluated by the conduct, not the outcome. Unauthorized trading, churning, and selling away remain violations even when the customer makes money.
A choice saying 'no violation because the customer's account increased in value' or 'because the client later ratified the trade.'
Guarantee-as-Reassurance Trap
The agent or firm offers to make the customer whole for any losses, framed as a customer-service gesture. Guaranteeing a customer against loss is flatly prohibited under NASAA's dishonest-and-unethical list, regardless of intent or financial capacity to honor the promise.
A choice that approves an agent's offer to 'personally cover any decline below the purchase price.'
Selling-Away Camouflage
The fact pattern dresses up an outside private offering as a 'favor for a friend,' a 'one-time investment opportunity,' or 'not really securities business.' If the instrument is a security and the agent participates in the offer or sale outside the firm without prior written notice and approval, it is selling away — prohibited regardless of the friendly framing.
A choice that excuses the agent because the LP units were 'sold to a personal acquaintance, not a brokerage customer.'
How it works
Think of the Act as having two layers. Layer one is §501 antifraud — broad enough to catch any material misstatement or omission tied to a securities transaction, and it follows the security even when the security itself is exempt from registration. Layer two is the NASAA list of dishonest and unethical practices, which lets the Administrator discipline agents and IARs for conduct that is sleazy without necessarily being fraudulent. Suppose Marcela, an agent at Whitfield Pacific Securities, executes ten unsolicited buys in a client's account before reaching the client to confirm; even if every trade was profitable and no lie was told, that is unauthorized trading and prohibited. Layer one would still apply if she had also told the client a bond was "AAA-rated" when it was not. Both layers can be charged at once, and remedies range from license suspension to civil and criminal penalties.
Worked examples
Under the Uniform Securities Act and NASAA model rules, which statement about Devon's conduct is MOST accurate?
- A No violation occurred because the client gave verbal authorization and the trades were profitable.
- B Devon violated state law by exercising discretion without prior written authorization, regardless of the profitable outcome. ✓ Correct
- C Devon's conduct is permissible because discretion over time and price does not require written authority.
- D The conduct is acceptable so long as the firm ratifies the trades within ten business days.
Why B is correct: Full discretion — choosing the security, action, and quantity — requires prior written authorization from the customer and acceptance of the account as discretionary by the broker-dealer before any discretionary trade is placed. Verbal permission and a profitable outcome do not cure the violation; the prohibition is against the conduct, not the result.
Why each wrong choice fails:
- A: Verbal authorization is insufficient for full discretion, and profitability is irrelevant to whether a prohibited practice occurred. (Verbal-Discretion Trap)
- C: The narrow time-and-price exception allows an agent to work an order the customer has already specified as to security, action, and amount; it does not authorize choosing the security itself. (Verbal-Discretion Trap)
- D: There is no 'ratification cure' under the USA. Written authorization must precede the discretionary trades, not follow them. (Profit-Means-No-Harm Fallacy)
Which of the following BEST describes Helena's potential liability under the Uniform Securities Act?
- A No antifraud liability attaches because the notes were sold in an exempt transaction.
- B Liability is limited to civil penalties because Helena did not personally profit from the sale.
- C Helena may be liable under §501 for misrepresentation and material omission, even though the transaction was exempt from registration. ✓ Correct
- D Liability requires proof of intent to defraud, which is absent on these facts.
Why C is correct: USA §501 applies to all securities transactions regardless of registration status. Equating an unsecured private note to a CD is a material misrepresentation, and the omitted auditor resignation was material to the investment decision. The Administrator may pursue Helena administratively, civilly, and criminally; an exemption from registration does not shield the conduct.
Why each wrong choice fails:
- A: Registration exemptions under §401–§402 do not displace the antifraud rule in §501. The Act expressly preserves antifraud reach over exempt transactions. (The Exempt-Security Escape Hatch)
- B: Personal profit is not an element of §501 fraud. Civil, administrative, and criminal remedies are all available regardless of whether the violator gained personally.
- D: §501 reaches negligent as well as intentional misstatements and omissions; specific intent to defraud is not required to establish a violation under state antifraud provisions.
Which statement about Tobias's conduct is MOST accurate under state law?
- A No violation because the partnership units are properly registered with the Administrator.
- B No violation because the transaction was conducted privately between neighbors and outside business hours.
- C Tobias engaged in selling away — a prohibited practice — by participating in a private securities transaction without prior written notice to and approval from his broker-dealer. ✓ Correct
- D Tobias may keep the referral fee provided he discloses it to the customer in writing within thirty days.
Why C is correct: An agent who participates in a private securities transaction outside the regular course of business with the broker-dealer must give prior written notice to the firm and, if compensation is involved, obtain prior written approval. Tobias did neither. The fact that the underlying offering is properly registered does not cure his selling-away violation, which targets the agent's conduct relative to the firm.
Why each wrong choice fails:
- A: Registration of the offering and the selling-away prohibition operate independently. A registered security can still be the subject of a prohibited selling-away transaction by the agent. (Selling-Away Camouflage)
- B: The 'friend, not customer' framing is precisely the camouflage NASAA targets. Selling away is judged by whether the agent participated in a securities transaction outside the firm, not by social context or hour. (Selling-Away Camouflage)
- D: After-the-fact disclosure to the customer does not satisfy the rule. The required notice and approval run from the agent to the broker-dealer and must be obtained before participating.

Key distinction
Registration exemptions excuse you from filing; antifraud provisions never exempt anyone. The security may be exempt, the transaction may be exempt, but §501 still applies to the conduct.
Summary
Under state law, fraud reaches every securities transaction regardless of exemption, and dishonest or unethical practices — especially unauthorized trading, churning, selling away, and guaranteeing against loss — are independently disciplinable even without a lie.
