Eh...I really don’t have the head for this, that is for sure.
The usual is to bond around the judgement, not to prepay it.
The Judge put a poisonous clause in his judgement. It states that Trump and his related defendants cannot borrow (money for bond) from any New York chartered bank or financial institution. Think about where most of the big banks do business.
If he prepays a judgment there is no easy method for an appeals court to get it back.
