In one sentenceSection 872.530 requires the plaintiff to join a known personal representative when a person with an interest has died, and otherwise lets the plaintiff join that person's testate and intestate successors by affidavit when the person is dead or believed to be dead and no personal representative is known.
(a)If a person described in Section 872.510 is dead and the plaintiff knows of a personal representative, the plaintiff shall join such personal representative as a defendant.
(b)If a person described in Section 872.510 is dead, or is believed by the plaintiff to be dead, and the plaintiff knows of no personal representative:
(1)The plaintiff shall state these facts in an affidavit filed with the complaint.
(2)Where it is stated in the affidavit that such person is dead, the plaintiff may join as defendants "the testate and intestate successors of ____ (naming such deceased person), deceased, and all persons claiming by, through, or under said decedent," naming them in that manner.
(3)Where it is stated in the affidavit that such person is believed to be dead, the plaintiff may join such person as a defendant, and he may also join "the testate and intestate successors of ____ (naming such person) believed to be deceased, and all persons claiming by, through, or under such person," naming them in that manner.
Plain-English Summary
Death complicates joinder, so this section supplies a specific procedure for it. If a person described in § 872.510 has died and the plaintiff knows of a personal representative -- an executor or administrator -- subdivision (a) requires joining that representative as a defendant.
If the person is dead, or the plaintiff believes them to be dead, and no personal representative is known, subdivision (b) offers an alternative. The plaintiff files an affidavit stating those facts, and then may join defendants by description rather than by name: "the testate and intestate successors of [name], deceased, and all persons claiming by, through, or under said decedent" when death is confirmed, or the parallel language referring to a person "believed to be deceased" when it isn't. That second version also lets the plaintiff join the possibly-deceased person individually, alongside their possible successors, covering the case either way.
