Have a lawyer make sure the person signing the bill of sale
has legal authority to do it.

This comes under the "Ask Me How I Know" category, even though I used
a "broker". A lawyer's interpretation may not be acceptable to the
FAA. You'll need some type of documentation that the person signing
the BOS has the authority to do. A death certificate and some other
specific (I can't recall now) documentation specifying authority is
the only thing the feds will accept. To place your mind at ease call
FAA Registrations and ask. You may also use AOPA's escrow service (if
it's still around).

That "something else" would be a piece of paper called a "letter of
administration." It should be signed (and optionally sealed) by the
court. It should identify, by name, the executor of the will. Get a
copy of this letter, along with a copy of the death certificate, and a
signed bill of sale.

Good Luck,
