Halt in assigned place (7)
I believe the answer is:
station
This clue is a double definition.
'halt' is the first definition.
(halt is a type of railway station)
'assigned place' is the second definition.
(as in someone's station in life)
'in' is the link.
(Other definitions for station that I've seen before include "Nine across stop" , "Such as Victoria" , "Headquarters" , "Waterloo perhaps" , "Chosen fixed point" .)
