Judge fools around heading for solicitors (6)
I believe the answer is:
assess
'judge' is the definition.
(to assess is to judge or rate)
'fools around heading for solicitors' is the wordplay.
'fools' becomes 'asses' (ass can mean a foolish person).
'around' indicates putting letters inside.
'heading for' indicates taking the first letters.
The initial letter of 'solicitors' is 's'.
'asses' going around 's' is 'ASSESS'.
(Other definitions for assess that I've seen before include "Fix the amount of tax" , "Evaluate worth" , "Weigh up, estimate value" , "Estimate value (for tax)" , "Place a value on" .)
