A New York judge on Friday increased pressure on former President Donald J. Trump’s family business and several associates, ordering them to give state investigators documents in a civil inquiry into whether the company misstated assets to get bank loans and tax benefits.
It was the second blow that the judge, Arthur F. Engoron of State Supreme Court in Manhattan, had dealt to Mr. Trump’s company in recent weeks.
In December, he ordered the company, the Trump Organization, to produce records that its lawyers had tried to shield, including some related to a Westchester County, N.Y., property that is among those being scrutinized by the New York State attorney general, Letitia James.
On Friday, Justice Engoron went further, saying that even more documents, as well as communications with a law firm hired by the Trump Organization, had to be handed over to Ms. James’s office. In doing so, he rejected the lawyers’ claim that the documents at issue were covered by attorney-client privilege.
The ruling was a fresh reminder that Mr. Trump — who left office about a week ago under the cloud of impeachment and is headed for a Senate trial on a charge of “incitement of insurrection” after his supporters stormed the Capitol in a violent rampage — faces significant legal jeopardy as a private citizen.
The most serious threats confronting the former president include a criminal investigation by the Manhattan district attorney and the civil inquiry by the attorney general into possible fraud in Mr. Trump’s business dealings before he was elected.
Ms. James’s investigation began in March 2019, after Michael D. Cohen, the former president’s onetime lawyer, told Congress that Mr. Trump had inflated his assets in financial statements to secure bank loans and understated them elsewhere to reduce his tax bill.
Investigators in Ms. James’s office have focused their attention on an array of transactions, including a financial restructuring of the Trump International Hotel & Tower in Chicago in 2010 that resulted in the Fortress Credit Corporation forgiving debt worth more than $100 million.
Ms. James’s office has said in court documents that the Trump Organization — Mr. Trump’s main business vehicle — had thwarted efforts to determine how that money was reflected in its tax filings, and whether it was declared as income, as the law typically requires.
An analysis of Mr. Trump’s financial records by The New York Times found that he had avoided federal income tax on almost all of the forgiven debt.
Ms. James’s office is also examining whether the Trump Organization used inflated appraisals when it received large tax breaks after promising to conserve land where its development efforts faltered, including at its Seven Springs estate in Westchester County.
Accusing the Trump Organization of trying to stall the inquiry, lawyers with Ms. James’s office sought a judge’s order in August compelling the company to turn over documents related to the Seven Springs estate and other properties, and requiring the former president’s son Eric Trump, a company vice president, to testify in the inquiry. (Eventually, he did.)
In December, Justice…
