My paper dictionary lists a number of 'non-xxx' and 'nonxxx' words. It 
has 'nonexistent' and not 'non-existent'. The Merriam-Webster also 
prefers 'nonexistent'.

http://www.merriam-webster.com/dictionary/nonexistent

Mozilla did a pass through their code replacing 'onn-existent' with 
'nonexistent':

However I'll acknowledge that a number of other online dictionaries 
seem to accept both forms. Maybe the explanation is in the Cambridge 
Dictionaries; they have 'non-existent' in the British dictionary and 
'nonexistent' in the US one.

http://dictionary.cambridge.org/dictionary/british/non-existent
http://dictionaries.cambridge.org/define.asp?key=nonexistent*1+0&dict=A

http://www.thefreedictionary.com/nonexistent
http://www.thefreedictionary.com/non-existent
http://dictionary.reference.com/browse/nonexistent
http://dictionary.reference.com/browse/non-existent

Overall 'nonexistent' seemed better referenced in the dictionaries and 
more 'legitimate'. But I can leave either form as is if that's 
preferred.
