Estate planning is a process to consider alternatives for, to think through, and to set up legally effective arrangements that would meet your specific wishes if something happens to you or those you care about. Good estate planning is more than just a simple Will. Estate planning also typically minimizes potential taxes and fees and sets up contingency planning to make sure your wishes regarding health care treatment are followed.
On the financial side, a good estate plan coordinates what would happen with your home, your investments, your business, your life insurance, your employee benefits (such as a 401K plan), and other property in the event you became disabled or if you die.
On the personal side, a good estate plan includes directions to carry out your wishes regarding health care matters, so that if you ever are unable to give the directions yourself, someone you select would do that for you, and know when you would want them to authorize heroic measures or when you would prefer they discontinue life support systems.
