You horse around with lawyer in a state (6)
I believe the answer is:
uganda
'state' is the definition.
(I know that Uganda is a African country)
'you horse around with lawyer' is the wordplay.
'you' becomes 'u' (homophones).
'horse' becomes 'nag' (term for an old horse).
'around' is a reversal indicator.
'with' is a charade indicator (letters next to each other).
'lawyer' becomes 'da' (abbreviation for District Attorney).
'nag' reversed gives 'gan'.
'u'+'gan'+'da'='UGANDA'
'in a' acts as a link.
(Other definitions for uganda that I've seen before include "East African republic" , "part of Africa" , "Kampala's nation" , "E. African country" , "Country bordering Lake Victoria" .)
