Some context would be helpful but my guess is that you are putting up money for the full amount of the bail.
If that is the case, "hilsincolorado", the person you're thinking about bonding out has done some VERY naughty things, is a flight risk, or has a lengthy criminal history of serious crimes, usually ALL of the aforementioned.
Be very careful, if you put up $50,000, you might never see a dollar of it returned.
Also, in some states (I don't know about CO, but you need to know), when the case is over the court releases the cash to the offender.
When that happens, the poor stiff who put up the cash never gets a dollar back.
You might wish to stay out of this, unless you've got lots of cash and don't care if you ever get it back.
