Cheat, deceive (7)
I believe the answer is:
defraud
This clue is a double definition.
'cheat' is the first definition.
(I know that defraud is a type of cheat)
'deceive' is the second definition.

(Other definitions for defraud that I've seen before include "Cheat, deceive" , "Deprive of by deceit" , "Get money from (someone) by deception" , "Illegally get money from (someone)" , "Swindle" .)
