I would like to know whether sending my acceptance of LLM in UCL for 2011/2012 and than decline it would imply the payment of some fee? My offer is conditional upon sending my English language proficiency results.

Im asking this as they request signing a firmly offer and sending it through post which implies some sort of commitment comparing to a online confirmation.

I didnt find anywhere saying that i should pay any amount for the case i subsequently decline my offer.

Any of you know more on this topic? I would really like to say yes but as i have an offer from KCL and want to study competition law i need more time to think especially due to the fact that both are conditional offers and i dont have my Toefl results yet.
