Practice point:  The party asserting that it has an easement by necessity bears the 
burden of establishing by clear and convincing evidence that there was a
 unity and subsequent separation of title, and that at the time of 
severance, an easement over the servient estate was absolutely necessary
 to obtain access to the party's land.
Student  note:  The necessity must exist in fact and not as a mere 
convenience, and must be indispensable to the reasonable use of the 
adjacent property.
