The purpose of a living will is long-term care planning. It can help make difficult decisions easier for your loved ones because you are able to explain your desires related to various decisions such as organ donations, DNR (do not resuscitate) orders, and other medical treatments. However, a living will is not the same as a power of attorney for health care or durable power of attorney. If you are interested in obtaining any type of power of attorney, you should seek legal advice.
18-C MRS §5-801 et seq.: Maine’s law, the Uniform Health-Care Decisions Act, states that living wills may be in writing or created orally. However, oral instruction is only valid if it is made to a healthcare provider or to the individual who will serve as the surrogate.
The Attorney General's website provides both a free advance directive and durable power of attorney for the public's use.
To further express your desires, create a Maine last will and testament as well.
