No more money given to former partner by court (7)
I believe the answer is:
extinct
'no more' is the definition.
(thesaurus)
'money given to former partner by court' is the wordplay.
'money' becomes 'tin' (I've seen this before**).
'given to' is a charade indicator (letters next to each other).
'former partner' becomes 'ex'.
'by' means one lot of letters go next to another.
'court' becomes 'ct'.
'tin' after 'ex' is 'extin'.
'extin'+'ct'='EXTINCT'
(Other definitions for extinct that I've seen before include "never to be seen again" , "Like a dodo" , "No longer living, like dinosaur" , "Defunct" , "No longer burning" .)
