My question involves bankruptcy in the state of: CA

I tried to look up the answer to this, but can't seem to find it online. Suppose I submit the paperwork to file for a chapter 7, but have not attended the hearing yet. Can I choose to delay or postpone the trustee hearing until a later date? Or, am I locked into it from the point that I file the petition?

Secondly, can I just call the whole thing off? Like, for example, I unexpectedly received a huge windfall of income and just somehow came into a lot of money. Could I just cancel it? What would be the consequences, outside of losing my attorney fees? Am i going to be penalized, like for 6 months of not being able to file again ... ? Or, no penalty in this case ... ???

If someone could shed light on this, I would appreciate it.
