There is no exact definition for "Estate (Legal Life) Planning." It is best described as a process - step taken in advance of disability, incapacity, and death - to provide for your health care and the disposition of your personal property and real estate. It is an ongoing process - not a one-time event - that is reviewed and updated as your family, financial situations, and relevant law change over your lifetime. Moreover, it is "stewardship."
