Carol responds:
Setting aside your propriety idea, which (sorry, Mike) doesn't have
any canon basis that I can see, I don't think that Voldemort saw any
need to cast a Fidelius charm, which involves *enclosing a secret
within a person*, the Secret Keeper, who is entrusted with the Secret
and is the only one who can reveal it. Obviously, as Fliss pointed
out, Voldemort doesn't trust anyone else enough to tell them the
secret and give them the ability to tell it, which he himself would
*not* be able to do. Voldie would want to be his own Secret Keeper if
that is possible. But since he alone already knew the secret and he
was not about to tell anyone (no one, he thought, could possibly be
clever enough to find his hiding places or get past the protections if
they did), he didn't think he needed to make himself his own Secret
Keeper through a spell since he was already his own secret keeper by
default as the only one who knew the secret. Does that make sense? His
hubris in thinking that no one could penetrate his secrets was his
downfall. IOW, the Fidelius Charm is not cast over a location or a
Horcrux or a person in hiding or whatever is being kept secret. It's
cast over the person who is *keeping* the secret to place the secret
inside them, perhaps analogous to *encasing* a soul bit in a Horcrux.

BTW, bboyminn said upthread that the Fidelius Charm on the Potters
broke when they died, which is also what Harry guesses, but that idea
is disproved in the Voldie flashback when Voldie watches the Potters,
who think they're still protected by the Fidelius Charm, which, the
narrator (seeing from Voldemort's pov) tells us is already broken.
We're back, IMO, to the idea of Fidelius meaning "faithful."
("Fidelis" = faithful, loyal, true.) Pettigrew has not been faithful.
He has broken faith with the Potters by revealing their secret to the
enemy who wants to kill them, and in doing so, has broken the spell
itself, making the Potters and their bodies and Baby!Harry visible to
Hagrid and everyone else. (BTW, I don't think that anyone except the
Potters, Black, Pettigrew, DD, and Lupin even knew there was or would
be a Fidelius charm until Pettigrew told Voldemort and broke the
charm. The whole idea would be to keep that information quiet, and
they only had a week between the casting and the breaking.)

To return to Voldemort, he isn't going to put his faith or trust in
anyone else, and he needs no spell to trust himself.
