Within the first year of purchase, many customers create their basic estate planning documents such as a living will. The advantage of keeping the subscription beyond that first year is the ability to update your estate plan to accurately accommodate for the life changes and milestones you and your family may experience.
However, if you feel that you got everything you need from the first year (ex. created a living will) and do not see additional value in renewing, you can elect to cancel your subscription prior to the renewal period.
