The defendant in a principal action by petition may bring in any person, including a codefendant, who is his warrantor, or who is or may be liable to him for all or part of the principal demand. In such cases the plaintiff in the principal action may assert any demand against the third party defendant arising out of or connected with the principal demand. The third party defendant thereupon shall plead his objections and defenses in the manner prescribed in Articles 921 through 969, 1003 through 1006, and 1035. He may reconvene against the plaintiff in the principal action or the third party plaintiff, on any demand arising out of or connected with the principal demand, in the manner prescribed in Articles 1061 through 1066.

Full Text of Art. 1111
Plain-English Summary
A third-party demand is Louisiana's device for pulling a new person into a lawsuit because that person may owe the defendant reimbursement, contribution, or a defense. Article 1111 lets the defendant — now acting as a third-party plaintiff — bring in by petition anyone who is the defendant's warrantor (someone contractually bound to defend or indemnify the defendant, such as a seller who warranted title to what's being sued over) or who is or may be liable to the defendant for all or part of the principal demand. The person brought in can even be a codefendant already in the case.
Once the third-party defendant is in the case, the lawsuit can grow in more than one direction. The original plaintiff can assert a demand directly against the third-party defendant, as long as it arises out of or connects with the principal demand — the plaintiff doesn't have to wait for a separate suit if the third-party defendant may also be responsible to the plaintiff. And the third-party defendant isn't limited to defending; the third-party defendant can reconvene against the plaintiff or against the third-party plaintiff (the original defendant) on any demand connected to the principal demand, following the reconventional-demand rules in Articles 1061 through 1066.
Article 1111 also anchors the third-party defendant's own defensive posture: the third-party defendant pleads objections and defenses the same way any defendant would, under Articles 921 through 969, 1003 through 1006, and 1035.
