What's the source on this?

I know it's a thing in Canada, Australia, and Washington state (if you cohabitate for some number of years, they can claim that it's a "de-facto relationship" and get property division). Apparently the current UK government is trying to push it

I looked up for Germany and found nothing

i could have sworn that this would be the case in germany too. but it turns out that there are practically no rights or obligations on separation except child support. property division only happens if both partners made a significant contribution, eg to a house. so if you pay for half of the house you can assume shared ownership of that house, but you may have to fight for it in court. you have to pay child support because it is the right of the child, which exists regardless of the relationship of the parents. another exception is financial support from the government. for that the income of your unmarried partner will be considered if you live in the same household, but that is obviously not relevant on separation.

the keyword to look up is "Eheähnliche Gemeinschaft".
