Indeed it should be 'condominium'. Condominium is the only term used by scholars (compare a Google Scholar search for 'Sudan condominium' with one for 'Sudan "co-dominium"'). Condominium is a seventeenth-century legal term for shared sovereignty, as defined in major dictionaries, including the OED. The hyphenation 'co-dominium' is rarely used in law, with most its scholarly occurences traceable to a single oddly-worded decision on Atlantic fisheries.
