When you are "shopping" for a lawyer, my advice is to use similar criteria as you would when looking for a specialist physician. Make sure that the lawyer is in fact specializing in the area of law that you need help in. Check out that lawyer's bio on his' or hers website. Ask what percentage of practice he or she devotes to your particular field.
Please do not make a mistake of applying for Life insurance if you believe you cannot disclose a part of your medical history or life style history. Its best to either consult with a lawyer re your particular situation before you apply or/ and consider other ways of securing financial future for your loved ones.
