Appeals Court Reverses Dismissal of Malpractice Claims Against Mintz Levin in Trust Dispute
An appellate panel has reversed the dismissal of legal malpractice and breach of fiduciary duty claims against the law firm Mintz Levin in a case stemming from a trust dispute, allowing the litigation to proceed.
Background of the Case
The lawsuit originated from allegations by a plaintiff identified as Sansom, who accused Mintz Levin and the estate of its former partner Richard Mintz of multiple violations related to the administration of the estate of Roland Holt. According to court filings, Sansom asserted claims including breach of fiduciary duty, legal malpractice, fraud, failure to account, and tortious interference with estate administration.

The claims centered on the firm’s handling of the estate, with Sansom alleging that Mintz Levin failed in its fiduciary responsibilities and committed professional negligence during the administration process.
Procedural History and Appellate Ruling
Initially, a lower court dismissed Sansom’s claims against Mintz Levin. However, upon appeal, the appellate panel reviewed the dismissal and determined that the claims should not have been thrown out at that stage of the proceedings.

The court’s decision to reverse the dismissal means that Sansom’s allegations of legal malpractice and breach of fiduciary duty will now be allowed to move forward in the legal process. The ruling does not determine the ultimate validity of the claims but permits the case to continue based on the sufficiency of the pleadings.
Context of Similar Litigation Involving Mintz Levin
This case is part of a broader pattern of litigation in which Mintz Levin has faced allegations of professional misconduct from former clients. In another matter, the firm is defending against a malpractice lawsuit filed by Parus Holdings Inc., a Texas-based voice technology company, which claims that Mintz Levin’s mishandling of patent proceedings before the U.S. Patent and Trademark Office’s Patent Trial and Appeal Board led to the invalidation of a core patent, potentially causing hundreds of millions in damages.
Mintz Levin has been involved in a separate fee dispute in Massachusetts, where it sought to halt the Texas-based malpractice case until a disagreement over a $2 million “success fee” was resolved. A federal judge in Massachusetts declined the firm’s request to pause the Texas litigation, allowing both cases to proceed independently.
In a prior appellate decision, the Eleventh Circuit Court of Appeals upheld a summary judgment in favor of Mintz Levin in a malpractice suit brought by a bankruptcy trustee representing the defunct biotech company Atherotech. The court ruled that the firm’s legal advice—regarding the legality of certain payments to physicians under uncertain legal standards—did not constitute negligence, even if later proven incorrect or incomplete.
Implications of the Ruling
The reversal of dismissal underscores that allegations against attorneys, particularly those involving fiduciary duties in trust and estate matters, are subject to close scrutiny when plaintiffs adequately plead their claims. It similarly highlights the ongoing legal challenges Mintz Levin faces across multiple jurisdictions concerning its professional conduct.
As the case returns to the lower court, both sides will proceed with discovery and further legal arguments. The outcome could have implications for how law firms manage their responsibilities in fiduciary roles and how courts evaluate claims of legal malpractice in complex trust administrations.
