Short answer. Two periods matter. Under Article 555 another person's possession displaces yours once it has lasted longer than one year — but the real right of possession is not lost until ten years have passed. The first date closes off the quick remedy; the second is when the right itself goes.
What the law says
By the possession of another, subject to the provisions of article 537, if the new possession has lasted longer than one year. But the real right of possession is not lost till after the lapse of ten years.

Why one year is the date people regret
The first year is when the law is at its most helpful to a dispossessed owner: the summary remedies exist precisely so that someone put off his land can get it back quickly, without the case turning into a full trial about ownership. Once the intruder's possession has run past a year, that route closes and what remains is slower, heavier and more expensive. Nothing about your ownership has changed. What has changed is the procedure available to vindicate it, and that difference is felt keenly by anyone who waited.
The ten years, and what it is not
The second sentence preserves the real right of possession for a decade, so an owner who has slept past the first year still has a right the law recognises for a good while longer. It is worth being clear that this is about possession rather than title. Losing the real right of possession after ten years does not by itself hand ownership to the occupant, and acquiring ownership by prescription has its own requirements — chiefly that the occupation be adverse, in the concept of owner, and not merely permitted.
The clock does not run on every kind of occupation
The article makes the one-year rule subject to the provisions of article 537, and that qualification does a great deal of work. Acts merely tolerated, and possession taken clandestinely without the possessor's knowledge or by violence, do not affect possession. So a relative or caretaker allowed to stay is not building up time against you, and neither is an entry you never knew about. What starts the clock is possession that is public, known and adverse — which is why the date you learned of the occupation is often the date that counts.
Establish when it began, then move
Pin the start with something dated: your own photographs, a barangay record, a letter of complaint, utility connections, the occupant's own improvements. Then send a written demand and keep proof of receipt, because a demand fixes the position and is normally a prerequisite to any action to recover. The single most useful thing on these facts is speed — the difference between month eleven and month thirteen is the difference between two entirely different lawsuits, and no amount of merit makes up for it.
