what is the normal rate for a bankruptcy chapter 7 and 13

There is not anything absolute. You should shop around, but consider experience and reputation as you may regret using the firm with the lowest cost.

In Chicago, I would expect a Chapter 7 legal fee to be $1500.00 or more. Chapter 13 usually works differently in that some or all of the fees are built into the plan payment. There is a presumed fee of $3500.00 that the courts except in Chapter 13 cases if the firm chooses to follow a standard fee arrangement, but firms are not required to do so.

There is not really an "normal" rate for a bankruptcy. There are the court costs -- $299 filing fee; and there are costs which seem to be the same -- credit counseling; debtors education; the fee to run a crediit bureau report. Each of them seem to run about $50. Pricing for legal services are totally different, I never urge anyone to use the "cheapest" services they can find. Interview a couple law firms and explain about your situation and ask what kind of work will be involved and ask them what they would charge -- find a law firm that you like and that you feel can do the job for what you consider a "reasonable rate."

Think of the matter as if you were having heart surgery -- would you ask which doctor was the cheapest? Or would you find a doctor that did the kind of work you wanted for the most "reasonable" price.

Good luck.
