I'm a little stuck... Click here to teach me more about this clue!

'authenticate documents' is the definition.
'notarise' can be an answer for 'authenticate' (I've seen this before). I am not sure about the 'documents' bit.

'senorita forged' is the wordplay.
'forged' indicates anagramming the letters.
'senorita' is an anagram of 'NOTARISE'.

Can you help me to learn more?

(Other definitions for notarise that I've seen before include "Authenticate" , "Officially attest" , "Witness official documents" , "Establish truth" , "establish an official record" .)

I've seen this clue in The Telegraph.
