Preparing a Will makes the most sense and ensures that the wishes of the Decedent shall be honored at death. A Will may be changed at any time while the decedent is living. If the decedent has no property, or everything is held in Joint tenancy with the decedent spouse, he/she may not need a Will, except if they die together in a plane crash or some other catastrophic event.
Also, if the party has set up a Trust and deposits all property in the Trust, he/she may not need a Will. Most people with Trusts do not keep all their property in the Trust, so they still need a Will.
If someone dies without a will, it is known as intestate. Learn more about
