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.
In the state of North Carolina, there are four ways to get a person out of jail: post the bond yourself, use property for collateral in court, have a judge release the defendant on their own recognizance, or hire a licensed and insured bail bondsman.
The bail bond agent will need you to sign some paperwork in order for you to secure their services. This usually means paying an amount to the agent, usually a percentage of the total bail amount, and signing off on any collateral for the bond.
Before giving us a call, make sure you have the following information handy: The full name of the person who was arrested. Where is the person being held for custody (you should include the name of jail, city, and county) The person's booking number.
