The term 'kind of will' can refer to four different types of wills: LIVING, ORAL, ILL, and FREE. A LIVING will is a document that outlines a person's wishes regarding medical treatment in the event they become incapacitated. An ORAL will is a verbal declaration of a person's wishes for their estate after death. An ILL will is a will that has been made under duress or undue influence. Finally, a FREE will is a will that has been made without any external pressure.
