What does consideration must be sufficient but need not be adequate mean?
It means that although consideration must provide some benefit
to the promisor or detriment to the promisee, these do not however
have a great deal. Providing something is given in return for a
promise, it does not matter that it is not much, or not what the
promise would usually be considered worth.Courts would not inquire
into the adequacy of consideration so long as there are some. The
reason for this rule is due to the old idea of freedom of contract,
which required that the parties themselves should be allowed to
make bargains that suit them without interference from courts.
