Section 1, Rule 70 of the Rules of Court requires that in
actions for forcible entry, the
plaintiff is allegedly
deprived of the possession of any land or building by force, intimidation,
threat, strategy, or stealth
and that the action is filed
any time within one year from the time of such unlawful deprivation of
possession, to wit:
SECTION 1. Who may institute proceedings, and when. – Subject to the
provisions of the next succeeding section, a person deprived of the
possession of any land or building by force, intimidation, threat, strategy,
or stealth, or a lessor, vendor, vendee, or other person against whom the
possession of any land or building is unlawfully withheld after the
expiration or termination of the right to hold possession by virtue of any
contract, express or implied, or the legal representatives or assigns of any
such lessor, vendor, vendee, or other person, may, at any time within one
(1) year after such unlawful deprivation or withholding of possession, bring
an action in the proper Municipal Trial Court against the person or persons
unlawfully withholding or depriving of possession, or any person or persons
claiming under them, for the restitution of such possession, together with
damages and costs.

This requirement implies that in such cases, the possession of the land by the
defendant is
unlawful from the beginning as he acquires possession thereof by unlawful
means. The plaintiff must allege and prove that he was
in prior physical possession of the property in litigation until he was
deprived thereof
by the defendant. If the alleged dispossession did not occur by any of the
means stated in section 1, Rule 70 either by force, intimidation, threat,
strategy or stealth, the proper recourse is to file a plenary action to
recover possession with the RTC. (Ong v. Parel, 407 Phil. 1045, 1053 (2001)
