@whowho,
Probably, yeah (although I don't think there are any "referees" involved--you mean referred). Both would pass, but "your death (demise, etc.)" would be more appropriate if "your" is used, in my opinion. "Your" tends to designate possession or ownership of some type of "thing," rather than something that sounds "active" like "passing away."
And maybe it's just me, but I wouldn't use "referred" if I was talking about something non-existent or counter-factual. Because there's nothing to really "refer" to if it's not there. Maybe the notice "presumed" rather than "referred." You could also say "putative death" as opposed to "referred."
Mark Twain once said that the reports of his death had been "greatly exaggerated," but, of course, that was meant to be humorous.
