How to Post Bail in Wisconsin: 5 Things to Know - Stuck in Jail)
"
10 Percent surety bond – The surety is not a bail bond agent, but instead is an adult 21 and older willing to help the defendant – most often a relative or close friend. For a $100,000 bond, for example, the defendant or individual surety pays $10,000 in cash to the court. Much of the money is returned, similar to a cash bond, making a surety bond without the help of a bail bond company a more affordable way for a defendant to get out of jail. Any individual surety can expect to prove he or she is financially solvent."
"The cost of a pre-trial release from jail is lower in a state such as Wisconsin with no private bail bond industry. The 10 to 20 percent that bail bond agents charge around the country is not an issue for defendants in Wisconsin. Instead, the cost need not be more than 10 percent of the bail – with much of that returned if the defendant shows up for all court hearings. A cash bond can be more expensive initially, but again, much of the money given to the court is returned when the defendant follows all release stipulations."
