my boyfriend was arrested for 475 (C)pc back in 12/09/08, i don't know what that is. Is he able to jus go to court and be fined or is their jail time involved?
There are several different ways to violate this code section, so which one your boyfriend violated depends on the police reports. Essentially, it's possession of a forged document (typically a check) with intent to pass it.
Whether he gets jail time or not depends on the facts of the case, his record and the judge/court/DA.
