Verified gold - afterwards dictate order (13)
I believe the answer is:
authenticated
'verified' is the definition.
(thesaurus)
'gold afterwards dictate order' is the wordplay.
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'afterwards' becomes 'then' (I've seen this in other clues).
'order' indicates anagramming the letters.
'dictate' anagrammed gives 'ticated'.
'au'+'then'+'ticated'='AUTHENTICATED'
(Other definitions for authenticated that I've seen before include "proved to be genuine" , "Validated" , "Established as genuine" , "Shown to be true" , "Certified" .)
