Seems like the French word concubinage which is a couple not legally binded.
For example me living with my BF is concubinage but if we register a civil union ( PACs or Marriage in France ) or stop living together we would be in the other categories.
We have the word concubine in English. Concubinage apparently is also a word in English but is not very commonly used. In most common English a concubine would refer to something like a member of a harem. Which I think either member of a modern unmarried couple would not be happy with such a comparison.
