"I oughtn't GO", for example, without "to" is perfectly correct and accepted standard English in the States, Dominic:-) Hate to disappoint youLOL
Now, "I ought TO...." in the affirmative MUST have "to", as "I ought go" is clearly substandard British, American, Canadian etc..
Foreigners aka non-native English speakers will often use/say "I oughtn't to go....", but it's not natural usage, as an English teacher, you can trust me on this one.
