Under the provisions of the Code of Civil Procedure, parties who have a mutual interest in a legal question or a question of fact may present it to the court for an opinion. To initiate this process, the parties must enter into a formal written agreement. This agreement serves to define the specific issue at hand, allowing the court to provide a binding opinion without the necessity of a full-scale trial.

Order IX of the Code of Civil Procedure, 1908, is titled 'Appearance of Parties and Consequence of Non-appearance'.

Order XXX of the Code of Civil Procedure, 1908, sets out the rules for filing suits by or against firms and persons carrying on business in names other than their own.

Order III of the Code of Civil Procedure, 1908, provides the legal framework for the appearance, application, and acts in court by recognized agents and pleaders.

Order XXVIII of the Code of Civil Procedure is dedicated to suits by or against military, naval, or air force personnel.

Section 80 of the Code of Civil Procedure (CPC) mandates that before a suit is instituted against the Government or a public officer in their official capacity, a formal notice must be served.

Order XII, Rule 1 of the Code of Civil Procedure allows any party to a suit to give notice by their pleadings or otherwise in writing that they admit the truth of the whole or any part of the case of the opposite party. This provision is intended to narrow down the issues in dispute and save the court's time by focusing only on contested matters.

Article 181 of the Limitation Act, 1908, is considered the residuary article. It applies to applications for which no period of limitation is provided elsewhere in the Schedule of the Limitation Act or by Section 48 of the Code of Civil Procedure.
