Upon the filing of the bill of complaint and the service of process upon the defendant, four methods of defense become available to the defendant, who can either:

(1) Disclaim,

(2) Demur,

(3) Plead, or

(4) Answer.

These four methods of defense will be the subject of the four succeeding chapters. A defendant may combine two or more of these defenses, as by disclaiming to part of the bill and demurring to the balance, or by demurring to one part and answering the remaining portion.
