Is it possible to put a note for future researchers to not seal a couple who are divorced and have died?
There is no way to prevent Ordinance being performed in the future.

You can put a 'Note' in a number of places; in fact, the SAME 'Note' in each of those places; but, unfortunately, that 'Note' DOES NOT guarantee that another Member User/Patron will NOT go ahead anyway and "Seal" such a "Couple".
Been there, done that ...
For such an IMPORTANT note, I like to add the SAME note in as many places as possible.
I would add the same note in ALL the following places:
(1) Person/Details ...
- Like Sketch
- Other Information - Customs Fact
... - Notes
... - Discussions (at least they CANNOT be "Deleted" by Others)
(2) Couple Relationship ...
- Relationship Notes
Some Member Users/Patrons will read such 'Notes' and disregard.
Some Member Users/Patrons DO NOT even read such 'Notes'.
Some Member Users/Patrons talk the 'stance' that it is NOT up to us to make such a judgement call (even with supporting evidence; as, I had).
You can only do what you can.
If another Member User/Patron comes along later (especially, after your passing) and does the Work; then, 'such is like'.
I have even "Reserved" and "Retained' the "Sealing to Spouse" so that no other User/Patrons could "Reserve" and undertake it, even to the extent of "Re-Reserving" after each x2 Year "Expiry" period; but, unfortunately, I missed a x2 Year "Expiry" period; and, within a day or two, it was 'schnavelled-up' by a Member User/Patron using one of those "Crawler" 'Bots', for "Green" Temple 'Icons'. That was disappointing.
There is know-way to stop such from happening.
I know that this does not help; but, I hope that it gives you some perspective.
