Coming from another ;
taken from something preceding ,
secondary ;
as derivative title ,
which is that acquired from another person .
There is considerable difference between an original and a derivative title .
When the acquisition is original ,
the right thus acquired to the thing becomes property ,
which must be unqualified and unlimited ,
and since no one but the occupant has any right to the thing ,
he must have the whole right of disposing of it .
But with regard to derivative acquisition ,
it may be otherwise ,
for the person from whom the thing is acquired may not have an unlimited right to it ,
or he may convey or transfer it with certain reservations of right .
Derivative title must always be by contract .
2 .
Derivative conveyances are ,
those which presuppose some other precedent conveyance ,
and serve only to enlarge ,
confirm ,
alter ,
restrain ,
restore ,
or transfer the interest granted by such original conveyance ,
