Beneficiary’s home — leading character seizing it meeting resistance (9)
I believe the answer is:
inheritor
'beneficiary's' is the definition.
(I've seen this before)
'home leading character seizing it meeting resistance' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in'**).
'leading character' becomes 'hero'.
'seizing' indicates putting letters inside.
'meeting' is a charade indicator (letters next to each other).
'resistance' becomes 'r' (abbreviation).
'hero' going around 'it' is 'herito'.
'in'+'herito'+'r'='INHERITOR'
(Other definitions for inheritor that I've seen before include "One mentioned in will" , "He comes into estate" , "Successor" , "Beneficiary under will" , "Heir" .)
