If you need a lawyer, you need to make sure you find one that is in the proper jurisdiction. Most of the time you will be able to find a lawyer that is licensed to practice in the state you live in. Make sure they are qualified to practice law within your state.
Look for people who have experienced similar problems and ask them which lawyers they used. Your friends and relatives might be helpful but do not follow their suggestions unless you need a lawyer for the same kind of issues. Use the different resources available in your community, such as support groups.
