Two or more parties may be joined in the same suit, either as plaintiffs or as defendants, if:
Art. 463.Cumulation, Plural Plaintiffs Or Defendants
Title II. Actions · Chapter 2. Cumulation of Actions · Amendment history unavailable · Last verified July 30, 2026
In one sentenceArticle 463 permits joining multiple plaintiffs or multiple defendants in one suit when there is a community of interest among the parties joined, each claim fits the court's jurisdiction and venue, and all the claims share a compatible procedure, again allowing alternative pleading of inconsistent claims.
Full Text of Art. 463
(1) There is a community of interest between the parties joined;
(2) Each of the actions cumulated is within the jurisdiction of the court and is brought in the proper venue; and
(3) All of the actions cumulated are mutually consistent and employ the same form of procedure.
Except as otherwise provided in Article3657, inconsistent or mutually exclusive actions may be cumulated in the same suit if pleaded in the alternative.
Plain-English Summary
Where Article 462 governs one plaintiff stacking claims against one defendant, Article 463 governs bringing more people into the case, several plaintiffs suing together, or several defendants sued together in a single suit.
The gateway condition is a community of interest between the parties being joined. That phrase asks whether the joined parties' claims or liabilities are connected closely enough to justify handling them together, sharing a common origin, a common set of facts, or a common question that makes joint handling sensible rather than forcing everyone into separate suits over related matters.
Two more conditions apply, echoing Article 462: each of the claims involved has to independently satisfy the court's jurisdiction and venue, and all the claims have to be mutually consistent and follow the same form of procedure. As with single-party cumulation, inconsistent or mutually exclusive claims can still be joined if pleaded in the alternative.
Frequently Asked Questions
What is a "community of interest" between joined parties?
A connection between the parties' claims or liabilities close enough, typically a shared transaction, occurrence, or question, to justify resolving them in one suit rather than several.
Can several plaintiffs sue one defendant together under this article?
Yes, provided the plaintiffs share a community of interest and each claim independently meets the court's jurisdiction and venue requirements.
Do all the joined defendants have to face identical claims?
No. The claims against them need to be mutually consistent and follow the same procedure, but they don't have to be identical, so long as a community of interest ties the parties together.
