the plaintiff has clear title supported by documents, if a trespasser without any claim to title or an interloper without any apparent title, merely denies the plaintiff's title, it does not amount to raising a cloud over the title of the plaintiff and it will not be necessary for the plaintiff to sue for declaration and a suit for injunction may be sufficient. Where the plaintiff, believing that defendant is only a trespasser or a wrongful claimant without title, files a mere suit for injunction, and in such a suit, the defendant discloses in his defence the details of the right or title claimed by him, which raises a serious dispute or cloud over plaintiff's title, then there is a need for the plaintiff, to amend the plaint and convert the suit into one for declaration. Alternatively, he may withdraw the suit for bare injunction, with permission of the court to file a comprehensive suit for declaration and injunction. He may file the suit for declaration with consequential relief, even after the suit for injunction is dismissed, where the suit raised only the issue of possession and not any issue of title"
