Judge's note about equally dividing property (8)
I believe the answer is:
estimate
'judge's' is the definition.
(estimating is a kind of judging)
'note about equally dividing property' is the wordplay.
I cannot quite see how this works, but
'note' could be 'ti' (musical note, as in do re mi so fa la ti do) and 'ti' is found within the answer.
'about' could be 'a' (abbreviation in Chambers) and 'a' is located in the answer.
'property' could be 'm' (M is an example) and 'm' is found in the answer.
The remaining letters 'este' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for estimate that I've seen before include "'Judge, calculate (8)'" , "rough judgment" , "Reckon value" , "Statement giving the likely cost of a job" , "Make an approximate assessment" .)
