A living will and a durable power of attorney for health care are two types of advance directives. They are both legal documents which you can use to help make your wishes for medical care known in the event you become unable to express them yourself. Because of the similarities, people sometimes wonder why they might need both documents in their estate plan.
Perhaps you created an estate plan years ago. Since then, your family has grown by marriages and births, you sold off a family business, and you acquired new property in a vacation home. Now, you need to update your estate plan due to your changing circumstances.
