Various hearings end in trouble for one served legal notice (9)
I believe the answer is:
garnishee
'one served legal notice' is the definition.
I can't tell whether this defines the answer.
'various hearings end in trouble' is the wordplay.
'various' is an anagram indicator.
'end in' suggests the final letters.
The last letter of 'trouble' is 'e'.
'hearings' anagrammed gives 'garnishe'.
'garnishe'+'e'='GARNISHEE'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for garnishee that I've seen before include "one warned against paying" , "I must pay creditor for another" .)
