Hand over before agreement (4,4)

Ross

I believe the answer is:

done deal

'agreement' is the definition.

'hand over before' is the wordplay.
'hand' becomes 'deal' ('deal' can be a synonym of 'hand').
'over' becomes 'done' (I've seen this before**).
'before' says to put letters next to each other.
'deal' after 'done' is 'DONE DEAL'.

I've seen this clue in The Guardian.
