If you notice that the lawyer you chose is not doing the job that you were expecting, do not be afraid to fire them. This is the person that you are paying your money for, so at any point you can cut ties. If you are facing a legal matter, you only want the best on your side.
Do not hire a lawyer until you know more about their experience and their results. A young lawyer might be more affordable but you will definitely benefit from hiring a more experienced and more successful lawyer. If possible, try finding a lawyer who has positive experience with very similar cases.
Do not hire any lawyer that makes you feel uncomfortable. You also need to be comfortable with the fees they are charging you. Don't sign blank checks for retainers. Get an cost estimate and do not let the lawyer have control over your wallet as well as the case.
Going to court and through the legal system is tough, no matter why you have to do it. Without a lawyer, it's nearly impossible to get what you are after.
