Had to leave husband and shift location (7)
I believe the answer is:
address
'location' is the definition.
(address is a kind of location)
'had to leave husband and shift' is the wordplay.
'to leave' suggests deleting specific letters.
'husband' becomes 'h'.
'and' means one lot of letters go next to another.
'shift' becomes 'dress' (I've seen this before).
'had' with 'h' removed is 'ad'.
'ad'+'dress'='ADDRESS'
(Other definitions for address that I've seen before include "One's postal residence." , "One's designated location" , "Speak to - direct" , "details on envelope" , "Call" .)
