Domestic fee charged in advance (8)
I believe the answer is:
retainer
I believe this clue is a double definition.
'domestic' is the first definition.
(a retainer is a term for a domestic servant)
'fee charged in advance' is the second definition.
(fee paid to retain someone's services)
(Other definitions for retainer that I've seen before include "Eritrean as kind of servant" , "Family servant of long standing - fee charged in advance" , "Family servant; barrister's fee" , "Fee; long-term servant" , "given payment in advance" .)
