The decision to post bail for someone should not be taken lightly. Financially, you risk losing the bail amount or collateral if the defendant fails to appear in court. Legally, the defendant's absence can lead to arrest warrants and additional charges, complicating their legal situation further.
No - if you signed the bond it doesn't matter whether you have a job or not - or whether the bondsman asked you if you did. You are liable as surety on the bond - having a job or not has nothing to do with your liability. Sorry.
That's called, "Release on own recognizance" or referred to as ROR. That's where, technically, you're not posting any bail, but technically under the law it's deemed to be bail. It's ROR.
The defendant can post their own bail or ask a family member or friend to post it. If the defendant uses a bond company, the company may require the defendant to have a co-signer (someone who will help the company find the defendant should they fail to appear).
Bailing someone out of jail who has a history of untrustworthy behavior can create headaches. You're essentially agreeing to put up 10 percent of a bail bond that could be tens of thousands — or even hundreds of thousands — of dollars. If they fail to show, then you went to all that extra trouble for nothing.
