Short answer. Under Article 543 of the Civil Code, an interruption in the possession of property held in common harms all co-owners, not just the one directly involved. When the interruption is civil — meaning it arises from a court filing — the Rules of Court govern exactly how and when that interruption takes effect.
What the law says
Interruption in the possession of the whole or a part of a thing possessed in common shall be to the prejudice of all the possessors. However, in case of civil interruption, the Rules of Court shall apply.

The basic rule: interruption falls on everyone
When several people co-own property and exercise possession over it, Article 543 treats that possession as shared. Any interruption — whether it cuts off possession of the whole property or just a portion — works against all the co-owners, not only the one who was directly in possession of the interrupted part. This means that if a third party successfully challenges the possession of one co-owner, the prescriptive period for all of them resets, and none can claim that their own portion was unaffected. The rule reflects the collective nature of co-possession: you stand together and you fall together.
What counts as a civil interruption
Interruption of possession can be natural — for example, if a flood or other event physically prevents possession for more than one year. Civil interruption is different: it arises from a judicial act, typically the filing of a complaint in court by or against one of the possessors. When someone files a case that puts the right to possess in question, that court action can break the running of the prescriptive period. The key point under Article 543 is that for this kind of interruption, the Rules of Court shall apply — meaning the procedural rules on when a suit is deemed commenced, when it is validly served, and what happens if the case is dismissed all govern whether the interruption actually took hold.
Why this matters if you are in a partition dispute
If you and your siblings co-own land inherited from a parent, and one sibling files a case asserting exclusive ownership over a portion, that filing may interrupt the prescriptive period for all of you — including siblings who had nothing to do with the dispute. This is particularly significant in situations where one co-owner has been quietly occupying the property for decades and is now arguing that prescription has converted their share into full ownership. A court filing by any co-owner at the right moment can reset that clock for everyone under Article 543. Whether the interruption was effective depends on whether the procedural requirements of the Rules of Court were properly met — service of summons, for instance, is often the deciding factor.
The retroactive treatment of co-possession
Article 543 also contains a protection for co-owners in good standing: each participant is deemed to have exclusively possessed the part allotted to them upon division, for the entire period of co-possession. This means that when the property is eventually partitioned, each co-owner is treated as if they had been in exclusive possession of their share from the very beginning — not just from the date of partition. This retroactive treatment can be important in inheritance cases, where heirs need to establish a prescriptive period running from before the property was formally divided. An interruption under Article 543 can complicate that calculation for all of them at once.
