The simple answer is immediately. Usually, death comes as a surprise to us all and no one is aware of their impending demise. Making a will represents doing the “right thing” today for those you love, and you should occasionally review your will to make sure it continues to represent your final wishes. If not – modify it. Also, almost everyone who dies owns some sort of personal property, therefore, everyone needs to provide their heirs with a will to prevent confusion or strife after their death. While state law will decide what happens to property in the estate of a person who dies intestate, the default plan normally distributes property to relatives. Therefore, a girlfriend, boyfriend, partner or fiancé will have no provision made for them by law unless provided by a valid will.
