In Cabrera v. Getaruela, the Court held that a complaint sufficiently alleges a cause of action for unlawful detainer if it recites the following:
(1) initially, possession of property by the defendant was by contract with or by tolerance of the plaintiff;
(2) eventually, such possession became illegal upon notice by plaintiff to defendant of the termination of the latter’s right of possession;
(3) thereafter, the defendant remained in possession of the property and deprived the plaintiff of the enjoyment thereof; and
(4) within one year from the last demand on defendant to vacate the property, the plaintiff instituted the complaint for ejectment VsG.R. No. 183822. January 18, 2012).
