What must be included in a reply to a counter-claim?

The choice indicating that all allegations must be addressed in a reply to a counter-claim is correct. In civil procedure, when a counter-claim is made by the defendant against the plaintiff, the plaintiff is obligated to respond to each allegation in the counter-claim. This ensures that all issues raised are considered and provides clarity to the court regarding the plaintiff’s position.

Addressing all allegations is crucial because it allows the plaintiff to contest the validity of the counter-claim, thereby defending against the additional claims made by the defendant. Failure to respond adequately could result in the court treating the allegations as admitted, which could adversely affect the plaintiff's case. Each part of the counter-claim should be met with a response that either admits, denies, or otherwise addresses those claims. This maintains the integrity of the pleadings and upholds the principle of fair trial, allowing both parties to have their arguments fully heard and adjudicated.

The other options suggest various misconceptions about the responsibilities of the plaintiff in this context. Ignoring the counter-claim could lead to adverse consequences, acknowledging only part of the claim does not fulfill procedural requirements, and the assertion that the plaintiff must prove their own case in the reply does not reflect the nature of a reply, which is typically
