Thomas St. John Lawsuit: Harris, Prydz, and Bankruptcy

The Thomas St. John lawsuits are a cluster of legal actions accusing the Hollywood-based music business manager of fraud, misappropriation, and breach of fiduciary duty, driven largely by clients whose money was tied to a stalled Hollywood real estate development. Calvin Harris, St. John’s most prominent former client, was awarded $13,438,666.55 in arbitration on January 15, 2026, and is still pursuing additional claims. Swedish DJ Eric Prydz filed a separate suit in October 2025. St. John’s U.S. company entered bankruptcy in early 2025 and was converted to Chapter 7 liquidation in June 2026.

Who Thomas St. John Is

St. John operated an entertainment and sports business management firm with offices in London and Los Angeles, providing financial services to electronic music clients including Calvin Harris, Eric Prydz, and Tiësto.¹ He managed Harris’s finances for roughly 13 years, from around 2012 until the relationship ended in April 2025.²

The Calvin Harris Arbitration

Harris filed an arbitration demand against St. John on September 12, 2025, alleging fraud, breach of contract, and malpractice.² According to Harris’s legal team, St. John solicited an emergency investment in 2023 after his Hollywood real estate project ran low on cash. St. John allegedly presented documents for signature without disclosing the nature of the project, inducing Harris to provide a $10 million loan and a $12.5 million equity investment.³

Harris’s attorneys alleged that shortly after receiving the $12.5 million, St. John distributed more than $11 million to an entity he controlled.⁴ The $10 million loan was due to be repaid by January 31, 2025. Neither principal nor interest was returned. Harris’s lawyers characterized the venture as a “boondoggle” and, “at worst, a complete fraud.”⁵

Retired federal judge Michael R. Wilner was appointed as arbitrator in August 2025 and initially issued a temporary injunction freezing certain assets to prevent dissipation of funds.⁴ On January 15, 2026, Wilner ruled in the first phase of the arbitration and ordered St. John and his associated entities to pay Harris $13,438,666.55, jointly and severally. The award covered $10 million in loan principal, roughly $2.67 million in interest, a $372,000 late charge, and $400,000 in origination and exit fees. Wilner found there was no dispute that the loan had not been repaid.⁶

That ruling resolved only the loan portion. The arbitrator has yet to rule on the $12.5 million equity investment or on the broader fraud allegations, and Harris is seeking the full $22.5 million.⁷

The CMNTY Culture Campus Project

The Harris money went into a proposed 460,000-square-foot Hollywood development called the CMNTY Culture Campus. The project originated with songwriter Philip Lawrence, a frequent Bruno Mars collaborator, who hired St. John in 2020 to help manage the sale of his music catalog. St. John brokered a $25 million loan from Tiësto to Lawrence at 9.6% interest so Lawrence could pay off a debt to Hipgnosis.⁸

After Lawrence sold his catalog to Tempo Music Investments for $90 million in 2021, the CMNTY project was structured partly to defer capital gains taxes. Lawrence and St. John set it up as a joint venture through Dun & Dun LLC, with Lawrence at 60% and St. John at 40%. Lawrence invested $3 million; St. John put in $2.4 million. St. John bought the Hollywood land in 2021.⁸

Lawrence’s financial situation worsened during a divorce, and he could not meet a $20 million investment commitment. St. John bought out Lawrence’s stake for his original $3 million and took sole control. Lawrence declared bankruptcy in 2023. The concept shifted from a creative campus with recording studios to a residential development of 750 apartments across two towers. St. John reportedly put around $70 million into the project through personal funds, debt, and outside investors.⁸

Construction never began. The project defaulted on at least one loan. Credit firm Parkview Financial, which had lent $35 million toward the project, sued St. John for $16.5 million plus interest.⁷ The property is now foreclosed.

The Eric Prydz Lawsuit

On October 28, 2025, Eric Prydz filed a separate suit against St. John in California state court, alleging fraud and theft of $269,000.⁹ Prydz accused St. John of paying himself $219,000 for services outside their 2023 “Terms of Business” agreement and making an additional unauthorized $50,000 withdrawal from Prydz’s accounts after the contract was terminated.¹⁰

Prydz also alleged that St. John refused to file mandatory tax documents due on October 15, 2025, unless Prydz paid an additional $150,000 for what the complaint calls “unapproved, out of scope” services. The suit seeks the $269,000 back plus punitive damages and legal costs.¹⁰ A representative for St. John told reporters the firm planned to “take all necessary legal action” to recover more than $187,000 it claimed Prydz owed.¹¹

The Philip Lawrence Bankruptcy Claims

A Chapter 7 trustee for Philip Lawrence’s estate, David K. Gottlieb, filed an adversary proceeding against Thomas St. John Inc., Dun & Dun LLC, and St. John personally, alleging fraudulent transfers under Section 548 of the Bankruptcy Code. The case was assigned to mediation in February 2026, with a status hearing set for August 2026.¹² The U.S. trustee overseeing Lawrence’s bankruptcy has separately alleged “acts of self-dealing” by St. John, including brokering the Tiësto loan without a proper license and buying out Lawrence’s stake for less than its value.⁸

Thomas St. John Inc. Bankruptcy

Thomas St. John Inc. filed for Chapter 11 bankruptcy on February 28, 2025, in the U.S. Bankruptcy Court for the Central District of California before Judge Barry Russell.¹³ Initial schedules listed assets between $0 and $50,000 and liabilities of $500,001 to $1 million, though general unsecured claims reportedly totaled about $11.3 million. Major creditors included the IRS ($4.1 million), the California Franchise Tax Board ($2.5 million), Jackson Lewis P.C. ($340,000), and Klar Consulting LLC ($211,000). Calvin Harris was not listed as a creditor.¹⁴

The company was unable to confirm a Chapter 11 reorganization plan. On June 5, 2026, the court converted the case to Chapter 7 liquidation, finding conversion was in the best interest of creditors. Howard M. Ehrenberg was appointed Chapter 7 trustee to gather and liquidate the estate’s remaining assets.¹⁵

St. John’s Response

Through attorney Sasha Frid, St. John has denied wrongdoing across the disputes. On the Harris claims, Frid said Harris “actively pursued” the CMNTY development and filed arbitration because he was “unhappy with the pace of the project.”³ The defense called the fraud accusations “malicious” and said Harris was a knowing investor who had sought to increase his stake in the project.⁸

On the development itself, the defense pointed to interest rates and market conditions as the reason for delays, and at one point projected a completed valuation above $900 million for a project featuring 750 apartments, low-income housing units, and creative and retail spaces.⁵ That projection became moot after the property went into foreclosure.⁷
