Place to see square, maybe, taken by joint authority (8)
I believe the answer is:
Here is my best explanation:
'place to see square maybe taken' is the definition.
I can't tell whether this definition defines the answer.
'by joint authority' is the wordplay.
'by' says to put letters next to each other.
'joint' becomes 'hip' (hip is a kind of joint).
'authority' becomes 'lords' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'hip' after 'lords' is 'LORDSHIP'.
