In Wisconsin, a complete Advance Directive requires the completion of two separate forms: a Living Will titled "Directive to Physicians and Family or Surrogates" and a "Power of Attorney for Health Care" (a.k.a. Health Care Proxy).

Required Information for the Living Will: You and two (2) witnesses need to sign your WI Living Will for it to be legitimate. Witnesses MUST be a minimum of 18 years old. Witnesses CAN NOT be:

• Relatives through blood, marriage, or adoption
• Directly responsible for your health care costs
• Persons who know they are entitled to a piece of your assets or have a claim to it
• A health care provider who is serving you at the time the document is signed, an employee of the health care provider who is not a chaplain or social worker, or an employee of an inpatient health care facility where you are a patient who is not a chaplain or social worker.
