And for years, the filing asserted, Mr. Trump’s company included the worth of Mr. Trump’s personal brand in some of its valuations of golf clubs, despite saying that it had not.
While Ms. James did not show that the company benefited from every valuation, her filing contended that the company broadly inflated its assets, which may have provided an overly rosy picture of Mr. Trump’s finances to lenders.
Ms. James’s lawyers also argued that Mr. Trump submitted at least two misleading statements to the Internal Revenue Service, saying that he substantially overstated the value of land at both his Seven Springs Estate in Westchester County and his Los Angeles Golf Club. The value of Seven Springs, Ms. James said, had been boosted by counting the value of seven nonexistent mansions, said to be worth $61 million. Mr. Trump received tax deductions worth millions of dollars on both properties.
Investigators accused the Trump Organization of calculating the value of Trump Tower by falsely inflating the size of Mr. Trump’s longtime home: While Mr. Trump had claimed since 2012 that his triplex penthouse apartment in the building was 30,000 square feet, he had signed documents stating its size as 10,996 square feet.
The additional square footage allowed the company to claim a $327 million value for the apartment in statements of financial condition. Ms. James said that Allen H. Weisselberg, the Trump Organization’s longtime chief financial officer, had said during questioning by Ms. James’s investigators that the apartment was overvalued by “give or take” $200 million.
Mr. Weisselberg, the filing contends, also falsely told one of Mr. Trump’s insurance companies that the property valuations were based on assessments by professional appraisers, when that was not the case. In reality, “the valuations were prepared by Trump Organization staff,” the filing said.
A lawyer for Mr. Weisselberg, Mary E. Mulligan, declined to comment.
Mr. Trump’s company is already under indictment in Manhattan. In July, the former Manhattan district attorney, Cyrus R. Vance Jr., charged the company and Mr. Weisselberg with carrying out a 15-year scheme to dole out off-the-books luxury perks to certain executives. That case is scheduled to head to trial later this year.
