Legal claims or defenses refer to the assertions made by parties in a legal dispute, where one party seeks to establish a right or entitlement, while the other party responds with reasons why that claim should not be granted. These elements are essential in pleadings as they set the stage for the court's examination of the case and dictate how each party will present their argument. Understanding these claims and defenses is crucial, as they frame the legal issues at stake and guide the entire litigation process.
