The heart of every estate plan is a will, also known as a last will and testament. This legal document puts you in control of who inherits your property and who would assume guardianship of your children if it were ever necessary. Without a will, state law will determine these issues. Your will allows you to name an executor ("personal representative") whose job it is to see that your wishes are carried out. And you can appoint a trusted person to manage property left to young people. With Quicken WillMaker, you can revise and update your will whenever you like.
