I believe the answer is:

incapacity

I'm a little stuck... Click here to teach me more about this clue!

'legal disqualification on the crown on a major town' is the definition.
I can't judge whether this definition defines the answer.

'disqualification on the crown on a major town' is the wordplay.
'disqualification on' becomes 'in' (I can't justify this - if you can you should give a lot more credence to this answer).
'the crown' becomes 'cap' (I've seen this in another clue).
'on' is a charade indicator (letters next to each other).
'major town' becomes 'city' (a city is a major settlement).
'in'+'cap'+'a'+'city'='INCAPACITY'
