Suing the Auditor After a Ponzi Scheme
By Matthew W. Reiser | Last reviewed September 30, 2026
Investors who lost money in a Ponzi scheme can sometimes recover from the accounting firm that audited the fund, but only on the right theory and with the right facts. In both California and Florida, an investor who was not the auditor's client usually cannot sue for ordinary negligence and must instead show that the auditor intended its report to reach and influence that investor, or that the auditor knew of the fraud and helped it continue.
Why the auditor matters
Audited financial statements are often the reason investors believed a fund was real. A clean audit opinion tells investors that an independent firm tested the fund's assets, its cash and its valuations. When the fund turns out to be a fraud, the person who ran it rarely has money left. The audit firm, its insurers and its partners often do.
Who can sue for a negligent audit
The California Supreme Court addressed this question in Bily v. Arthur Young & Co., 3 Cal. 4th 370 (1992). The court held that an auditor's duty of care in performing an audit runs to its client, not to every investor or lender who later reads the report. The court allowed a narrower claim for negligent misrepresentation by persons who are specifically intended beneficiaries of the audit report, known to the auditor, for whose benefit the auditor renders the report. Id. at 407. Investors can also sue an auditor for intentional fraud if the auditor knowingly issued a false opinion.
Florida law likewise limits negligence claims by people who were not the auditor's client, and focuses on whether the auditor knew that a particular investor or group would rely on its work. The details of the fund's structure matter: who engaged the auditor, whether the audit report was distributed to investors, and whether the auditor knew that was happening.
Aiding and abetting the fraud
The second path is a claim that the auditor aided and abetted the fraud or the manager's breach of fiduciary duty. That claim generally requires proof that the auditor actually knew of the wrongdoing and gave substantial assistance. Constructive knowledge, meaning the auditor should have known, is generally not enough. Evidence that can support actual knowledge includes internal workpapers flagging problems the engagement team chose not to pursue, confirmations that were never returned, and valuations the auditor accepted without testing.
Claims by the receiver
When a court appoints a receiver over the collapsed fund, the receiver may bring its own claims against the auditor on behalf of the fund. Auditors often respond that the receiver stands in the shoes of the entity that committed the fraud and cannot recover for it. Courts treat that defense differently depending on the jurisdiction and the facts. Investors should understand whether the receiver is pursuing the auditor before deciding whether to bring their own claims, because the two can compete for the same insurance and the same assets.
What to gather
- Subscription documents and any offering memorandum describing the auditor
- Every audited financial statement and audit opinion you received, and how you received it
- Account statements and capital account reports
- Communications from the manager referencing the audit
- Any receiver or regulator notices
Deadlines
Limitations periods for negligence, negligent misrepresentation and fraud claims against auditors are often short and generally run from when an investor discovered, or should have discovered, the facts. A regulator's complaint or a receiver's report can start that clock.
