Specify as a condition (9)
I believe the answer is:
stipulate
'specify as a condition' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for stipulate that I've seen before include "Insist on as part of agreement" , "Demand, specify" , "Demand as part of agreement" , "Specify as a condition or requirement" , "Make a demand" .)
