If you violate your contract by failing to pay the bond company the agreed-upon amount while you are out of jail awaiting your hearing, you should get in touch with the bail bonds firm. They will typically work with you to modify the payment schedule. The bond company will come after you and throw you back in jail if you don’t let them know about the payment, and the money you paid is forfeited.
You won’t be able to get it back, and you’ll also be locked in jail. Then, the only option to get out of jail is to either find a new bond business and pay the 10% bond cost again, or to pay the full amount of the bail to the court.
