Hotel documents for auditor (4)
I believe the answer is:
ritz
'hotel' is the definition.
(I've seen this before)
'documents for auditor' is the wordplay.
'documents' becomes 'writs' (writ is a kind of document).
'for auditor' indicates a 'sounds like' (homophone) clue.
'writs' is a homophone of 'RITZ'.
(Other definitions for ritz that I've seen before include "Cesar --, Swiss hotelier" , "Classy hotel" , "The Diamond as Big as the ___ (F. Scott Fitzgerald)" , "glamour" , "Swiss hotelier, who founded an international chain, d. 1918" .)
