A performance bond is what a construction contractor purchases when entering into a contract. It is called due if the contractor fails to complete the project as the contract dictates.
I have never heard the term “performance bond” used along with criminal court.
Regardless, a performance bond is a form of surety bond
Regardless, from what you have stated nobody paid the full purchase price of the bond and that is what the bond agent is seeking
If the bond was called due, you would be on the hook for the full amount, which I’m presuming was $250,000.
