Summarize this article:

At the meeting, raise any concerns you have over billing, communication, or the representation generally. Sometimes the attorney may have a reasonable explanation.  Lawyers are people, too. Sometimes a billing error may be a simple mistake, or a phone call might not get returned because your lawyer has suffered a health problem. However, a pattern of mistakes signals negligence. Send a follow-up email in which you summarize the contents of the meeting. This will provide you with a paper record. Most attorneys will be honest with you about how well, or how poorly, another lawyer is handling your case. Take copies of the pleadings and correspondence to another lawyer for a critique of your current lawyer's progress. If after meeting with your lawyer and getting a second opinion you think that your attorney has not represented you adequately, then you should terminate the representation. You should write a letter to this effect.  Summarize briefly why you are unhappy with the lawyer. If you have already met with your attorney, he should have a good idea of why you are unhappy with his representation. Then simply write, “As of [today's date], I no longer want you to be my lawyer.” Send the letter certified mail, with a request for a signed receipt. Request a copy of your file. Even if you fire your lawyer, you are responsible for paying any outstanding fees. Your lawyer might sue you to recover the unpaid balance of your bill. Many websites allow clients to rate their lawyer on effectiveness and professionalism. If you think others should avoid your lawyer, feel free to share your experiences at websites like Avvo. Remember that information shared on the web is public. If you have an ongoing legal matter, the other side can see anything that you share about your case. Be careful not to reveal too much. If you think your lawyer has violated the ethics rules or broken the law, then you should report him to the appropriate disciplinary board in your state. The board will want documentation, such as billing records and your emails or letters. You should already have this information.
Schedule a meeting with your lawyer. Get a second opinion. Write a letter terminating the representation. Pay your bill. Warn others. Report your attorney to the Disciplinary Board.
