The Scottish relationship with the EU is likely to change after independence.
The Scottish Government claims that an independent Scotland would be able to join the EU with all the UK's various opt outs intact. Scotland indeed could not be forced to join the Euro because in order to do so it would have to demonstrate currency convergence for at least two years which the newly independent state obviously would not be in a position to do.[1] Therefore if Scotland retained UK opt outs there would be only a positive change in relationship with Scotland receiving greater representation in EU institutions through having its own seat in the Council of Ministers, possibly its own Commissioner, and also a reallocation of European Parliamentary constituencies that would increase its representation there (and paradoxically increase rUK representation as well).[2] [1] Noon, Stephen, ‘Euro membership’, 10 November 2011, http://stephennoon.blogspot.co.uk/2011/11/euro-membership.html [2] Engel, Arno, and Parkes, Roderick, ‘Accommodating an independent Scotland: how a British-style constitution for the EU could secure Scotland’s future’, European Policy Centre, 24 October 2012, http://www.epc.eu/documents/uploads/pub_3017_scotland_s_future.pdf p.7
