Bankrupcy under California law is really the same as other states' Bankrupcy programs, witih some minor differences. You see, bankrupcy is governed by Federal law, and you'll be in federal court. So, if you're a CA resident, you'll want to file your California Bankrupcy in a Federal court in your local jurisdiction.
Like most complicated and confusing things involving the law, you're probably best not trying this yourself, though you certainly can. It's probably better to work with a California Bankrupcy attorney who is licensed in your local district.
However, one of the most important things to know about are the California Bankrupcy exemptions, as these can help you protect your property from your creditors. They are constantly changing by the state legislature, so check the law before filing Bankrupcy.
