Pulpits out of sorts with divorce
I believe the answer is:
split up
'divorce' is the definition.
('split up' can be a synonym of 'divorce')
'pulpits out of sorts' is the wordplay.
'out of sorts' is an anagram indicator.
'pulpits' anagrammed gives 'SPLIT UP'.
'with' is the link.
(Other definitions for split up that I've seen before include "End a relationship" , "Part company" , "Take apart" , "Parted company" , "Separate" .)
