I dont share the same last name as her or my uncle, i live in Canada and the notarization won't be an issue its moreso just wondering if they'll accept it. I called my airline and they said they had no issue its more about uk customs! The issue isn't distance its basically that my mom kicked me out of her house and i live with other family now. I figure if its a notarized document explaining my situation and everything that I will be doing in the Uk and who i will be staying with that if they ask for it, it will be sufficient?
