Formally turn over (4)
I believe the answer is:
cede
'formally turn over' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for cede that I've seen before include "Surrender or grant" , "Give up (eg, power)" , "Reluctantly give up" , "Yield, give way" , "Surrender or relinquish possession" .)
