Art. 4652.  Claimants who may be impleaded

Persons having competing or conflicting claims may be impleaded in a concursus proceeding even though the person against whom the claims are asserted denies liability in whole or in part to any or all of the claimants, and whether or not their claims, or the titles on which the claims depend, have a common origin, or are identical or independent of each other.

No claimant may be impleaded in a concursus proceeding whose claim has been prosecuted to judgment.  No person claiming damages for wrongful death or for physical injuries may be impleaded in a concursus proceeding, except by a casualty insurer which admits liability for the full amount of the insurance coverage, and has deposited this sum into the registry of the court.
