EDIT So I'm hearing it's the BOND COMPANY that needs to put this up, not Trump. So it's the financial statment of the insurance company that put up the bond.
You can appeal without putting up a bond, Trump has already started his appeal.
BUT without a bond you can't STAY or pause the execution of the judgement...that is the collection of the money.
The bond protects both the plaintiff and the defendant. Let's say I smashed by boat into your lake house. And you sue me and win a $200,000 judgment. You want to be sure I have the money and I not just appealing to delay you getting the money. I want a way to easily get my money back if I win my appeal. The court wants to be sure my appeal isn't frivolous and I'm not just wasting everyone's time.
