Judge Arthur Engoron is expected to rule in Trump's civil fraud trial. The fine could be steep.

Trump could secure a bond, but it will cost him

So if Mr Trump owed $370m in disgorgement, he might have to pay a bond company $37m (£29m) to issue the bond. And he will not get that fee back.

Trump could sell assets to raise enough cash

“Something is going to have to be sold or realised in order to get the money to pay for that kind of cost,” said William Thomas, a professor at the University of Michigan Ross School of Business.

Trump could ask his loyal supporters for the money

Mr Trump may also turn to the massive fundraising engine he uses to pay his tens of millions in legal fees. According to the New York Times, 10% of every dollar that is raised from his supporters goes to pay for his defence in his civil and criminal trials.
