Calvin Harris is taking legal action against his longtime financial adviser, Thomas St. John, accusing him of misusing $22.5 million invested in a Hollywood real estate project.
The allegations were detailed in court documents filed on Friday, September 12th, 2025, where Harris (real name Adam Wiles) petitioned to enforce a temporary injunction tied to ongoing arbitration. The private dispute, which began in June, includes claims of fraud, malpractice, and breach of contract.
“Out of necessity, Mr. Wiles surrounds himself with professionals, including TSJ, in whom Mr. Wiles placed his trust to ensure his earnings are protected, his investments are smart, and his family and future are secure,” the filing reads. “However, instead of acting in Mr. Wiles’s best interests, TSJ and the other respondents completely and absolutely breached that trust.”
Harris says St. John bought land in Hollywood in 2021 to develop a recording studio. In 2023, he allegedly persuaded Harris to invest $22.5 million — $10 million as a loan and $12.5 million in equity. The loan was never repaid, and the project never broke ground. Instead, Harris claims, St. John redirected over $11 million to himself.
“Mr. Wiles has not received a single penny in return for that investment, and, indeed, respondents have not even started developing or building the project,” the demand states.
The project’s focus has since shifted toward residential development. In August, Judge Michael R. Wilner was appointed arbitrator, and a temporary injunction freezing assets is now in place.
St. John’s attorney, Sasha Frid, says his client “denies any wrongdoing” and that Harris “actively pursued” the investment. “The development is very much viable and expected to have a $900+ million valuation when completed,” he said.
