During your consultation and at anytime with the lawyer that you choose, DO NOT BE AFRAID TO ASK QUESTIONS!!! They've spent years going to law school and you're paying them a small fortune. You have every right to ask questions - no matter how silly you think they think you are. You need to be informed about every aspect of your case. Make sure to get copies of all documents and forms.
Talk to others about reccommendations - good and bad! Finding out the bad is just as important as the good. Like I said before, this is someone you're trusting with very personal and confidential information. You need to feel comfortable with them. And you don't want to get stuck with someone who's going to screw you over.
A couple of side notes directly related to bankruptcy cases. You can handle the bankruptcy yourself or work with a "pro-se," or someone who is qualified to help you through the process. You still do the work and the filing yourself, but you get a little help along the way. However, the bankruptcy process is very technical and must be done in a very exact way. You can read more about filing for bankruptcy without a lawyer at USCourts.gov.
Also, beware of scams claiming that they can erase your debt, even when they claim they can do it "legally." Beware of companies who claim that they will negotiate with your creditors for you. There are a lot of companies out there that will claim they're working with your creditors, that you should pay them, and then they'll distribute your money. Chances are, they're just going to be taking your money on a monthly basis and you'll continue getting calls from creditors.
Do you have any additional tips for finding a good lawyer (for any type of legal case)?
