I even lived in a shared flat with two other women during my studies, where we as a flatshare had to prove that we were not in a marital-like relationship. And that was long before same-sex marriages were recognized in any form. Not to mention polyamory.
But they don’t end up empty-handed because they’re not gay. They end up empty-handed because the couple in the same-sex marriage signed the marriage certificate, and the couple with children simply did not. Personally, I can hardly understand why couples with children can’t bring themselves to get married. A child binds ten times more than a marriage certificate. Why do these people resist marriage? Is it because it’s such an archaic construct / institution? In my mind, marriage is the “official” form of the relationship. Just because it’s now also available to same-sex couples doesn’t mean it’s taken away from heterosexual couples, right?
Divorces in Germany are still very, very expensive. Thanks to mandatory attorney involvement, etc. Even if there are no children, no assets, and the separation is amicable, you have to pay a few thousand euros for a piece of paper. It’s almost like a subscription trap. You can marry quickly and cheaply. Divorce, on the other hand, is complicated and expensive. :)
The whole family law is very archaic.
