Authorise payment: it legally binds (7)

I believe the answer is:

entitle

'authorise' is the definition.
(I know that entitle has the is a more specific form of the action authorise)

'payment it legally binds' is the wordplay.
'binds' indicates the answer is hidden within the clue (the answer is bound within the clue).
'ENTITLE' is hidden in the letters of 'payment it legally'.

(Other definitions for entitle that I've seen before include "Warrant" , "Name, authorise" , "Name; enable" , "Call; permit" , "Furnish with a right or claim" .)

I've seen this clue in The Times.
