It is hugely important that you know exactly what your lawyer plans to do for you. They should lay it out in writing, preferably, before you sign on the dotted line. If they get you to sign a legal document they have drafted without explaining it, run the other way.
Make sure you understand the costs associated with a particular lawyer ahead of time. Before you even begin the process of seeking someone out, you need to think about what you can afford. As you call different lawyers, discuss fees and the payment schedule. Do not be surprised later on!
Do your research prior to hiring any lawyer. You may get the itch to get it over with and just choose someone from the Yellow Pages. Don't do it! You won't be happy with the outcome. Instead, research lawyers who could perform best for you. Track down some referrals (they may be online) and get an idea about his or her personality and track record. It'll make your situation much better.
