lien

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

'right legally' is the definition.
'lien' can be an answer for 'right' (legal right). I'm not sure about the 'legally' bit.

'inalienable' is the wordplay.
'LIEN' is hidden in amongst the letters.
But, I am not sure how this is indicated.

Can you help me to learn more?
