Crossword Genius

Unhappily, Ant pursued intention to divorce (3,7)

Ross

I believe the answer is:

put asunder

'intention to divorce' is the definition.
(to put asunder is to split or separate)

'unhappily ant pursued' is the wordplay.
'unhappily' indicates anagramming the letters.
'ant'+'pursued'='antpursued'
'antpursued' is an anagram of 'PUT ASUNDER'.
