Because of the gravity of the decisions associated with a living will and the potential severity of the results, a living will must be witnessed by individuals who can swear that the document reflects the maker's wishes. These witnesses must be independent, and can't have an interest in receiving your property after your death. They shouldn't be related to you or be responsible for your health care bills. In other words, you should have witnesses that will not profit by making decisions against your best interests. Finally, your living will witness should not be your healthcare provider, or a person affiliated with a community care or residential care facility.
