An Administrator (or Administratrix) is the person appointed by the court to handle the estate of someone who died without a will, with a will but no nominated executor, or the executor named in the will has died, has been removed from the case or does not desire to serve. If there is a will but no available executor, the administrator is called an “administrator with will annexed.” Dictionary.Law.Com. An administrator is a fiduciary.
Property left to a person for their life creates a life estate. The person is a life tenant. When the life tenant dies, the property (or remainder) goes to another, called the remainderman.
