Defense Verdict Secured in FINRA Arbitration Matter
We obtained a defense verdict in a FINRA arbitration where the claimant donated approximately $600,000 to a donor advised fund in 2012 and took a tax deduction. The claimant alleged that the donor advised fund was mismanaged and lost approximately $140,000 in value in 2022. We defended the fund’s managers in the case based upon the claimant’s lack of standing once the funds were donated. Further, we presented evidence through the respondent’s testimony that the account was managed in accordance with the goals and objectives set for the account. In addition, we presented evidence that the account was overall profitable and performed better than the S&P 500 index during the relevant time period.

FINRA Fines and Suspends Former Financial Advisor for Naming His Wife and Children as Beneficiaries on a Client’s Account
January 1, 2026
A former financial advisor was suspended for eight months and fined $5,000 after he allegedly violated FINRA Rule 2010. FINRA Rule 2010 provides that “a member, in the conduct of its business, shall observe high standards of commercial honor and just and equitable principles of trade.” In this case, FINRA found that the financial advisor permitted one of his clients to name the advisor’s wife and children as beneficiaries on the client’s accounts without the firm’s approval. The advisor signed a letter of acceptance, waiver and consent to FINRA’s findings without admitting or denying them.
