FINRA has suspended registered representative William David Miller for failing to provide information requested during an investigation, marking another enforcement action tied to Rule 8210 compliance failures at broker-dealer firms Osaic Wealth and Woodbury Financial.
What happened
FINRA issued an Acceptance, Waiver and Consent agreement against Miller in connection with the regulator’s request for documents and testimony. The findings show that Miller failed to respond to FINRA’s requests for information, prompting the self-regulatory organization to suspend his registration.
Rule 8210 requires registered representatives to provide testimony, documents, and other materials when FINRA conducts an inquiry. The rule is a cornerstone of FINRA’s investigative authority, and violations typically result in immediate suspension.

Broker details
Miller was registered with Osaic Wealth Inc., a network of independent financial advisors, and Woodbury Financial Services Inc., a broker-dealer offering investment products to retail clients. Both firms operate under the Osaic corporate umbrella, which provides compliance infrastructure for affiliated advisors.
When a broker fails to respond to FINRA inquiries, the regulator typically imposes an immediate suspension. This prevents the individual from conducting securities business while the investigation remains open. The suspension also signals to investors that the broker may have unresolved compliance matters.
What investors should know
Investors who worked with Miller at Osaic Wealth or Woodbury Financial should review their account statements for unusual trading patterns, unauthorized transactions, or investments that did not match their stated risk tolerance. Account documentation from the period of Miller’s registration can reveal whether suitability standards were followed.
FINRA’s BrokerCheck database contains disclosure history for Miller and his former firms. Investors can search the broker’s name at brokercheck.finra.org to view any past customer complaints, regulatory actions, or employment terminations.
What affected investors can do now
- Request a complete copy of your account history from Osaic Wealth or Woodbury Financial.
- Compare promised investment strategies against actual holdings and trades.
- Document any communications that seemed evasive or incomplete.
- Consult a securities attorney if losses appear linked to unsuitable recommendations.
Common mistakes victims make
Many investors delay reviewing their accounts after a broker’s suspension, assuming the issue is purely administrative. This is a mistake. Rule 8210 suspensions sometimes precede or follow more serious allegations. Waiting too long can mean missing filing deadlines under FINRA arbitration rules.
Another common error is signing a release or settlement agreement with the broker-dealer without independent legal review. Firms often present these documents as routine account closures, but they may waive valuable claims. Investors should have any release reviewed by counsel before signing.
Regulatory context
FINRA Rule 8210 is one of the most frequently cited provisions in broker disciplinary actions. It gives FINRA broad authority to compel testimony and documents from registered persons and member firms. The rule serves as a backstop — when brokers refuse to cooperate, FINRA can suspend them immediately, preserving investor protection while the underlying investigation proceeds.
In 2025 and 2026, FINRA has increased the pace of Rule 8210 suspensions, signaling a stricter posture on compliance cooperation. The regulator has stated repeatedly that full cooperation is a condition of maintaining good standing in the securities industry.
