Art. 1093.Service of Petition; Citation Unnecessary

Service requirements for an intervention depend on what kind of intervention it is. Article 1093 splits interventions into two categories. An intervention that asserts ownership of, or a mortgage or privilege on, seized property has to be served on the sheriff — who has custody of the property and needs notice of the competing claim — as well as on all the parties to the principal action, following the method Article 1313 prescribes.

Any other kind of intervention follows a simpler path: service on all parties to the principal action under Article 1314, the same general service method used for reconventional demands and cross-claims. There's no sheriff to notify because there's no seized property in play.

Either way, citation isn't required. Article 1093 states directly that citation is not necessary in intervention, whether the intervener is asserting a claim to seized property or joining the case for some other reason.
