Above the Law discusses the importance of having a Last Will And Testament, Power Of Attorney, And Healthcare Proxy:

Like an annual physical exam or dental cleaning, we know we must, but we often delay. Fear, anxiety, cost, and time are all factors in delaying that which all adults, regardless of familial structure and net worth, should accomplish. Executing estate planning documents, specifically a last will and testament, power of attorney and healthcare proxy, need not be a tremendous production, especially in the precarious times in which we live. At a minimum, we should all execute three basic documents, thus mitigating any future drama.
