A New York judge on Friday formally ordered Donald Trump to pay $454 million, including interest, a move that will give the former president one month to post nearly half a billion dollars to appeal the fraud verdict.

Judge Arthur Engoron’s signed judgment was posted to the court docket Friday, one week after he found Trump, Donald Trump Jr. and Eric Trump liable for fraud in the civil case brought by New York Attorney General Letita James.

Once Trump and the others are served with the judgment, the 30-day clock for them to file an appeal starts. During that period Trump will need to put up cash or post bond to cover the $355 million and additional roughly $100 million in interest he was ordered to pay. The sons were each ordered to pay $4 million back in gains they improperly received because of the fraud. The judge also banned the Trumps from serving as officers of a business entity in New York for several years.
