'letting fee indicated below' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'torn apart by' is the wordplay.
'torn' becomes 'rent' (rending is a kind of tearing).
'apart' becomes 'asunder' (synonyms).
'by' is a charade indicator (letters next to each other).
'rent'+'asunder'='RENT ASUNDER'
