#5. Secure/Update Health Care Documents.
At the minimum, everyone over the age of 18 needs...
1) a durable power of attorney for health care, which gives another person legal authority to make health care decisions (including life and death decisions) for you if you are unable to make them for yourself; and
2) HIPPA authorizations, which give written consent for doctors to discuss your medical situation with others, including family members.
In addition, a revocable living trust is preferable over a will at incapacity because it can prevent the court from controlling your assets.
