Not everywhere. In Slovenia (and some other countries probably), we have a "zunajzakonska skupnost", which rougly translated means "out-of-wedlock relationship". If two people live together for a (undefined) "long" amount of time, and act in a way married couple do, they can be treated exactly as a married couple would be. That means, that one of the partners can claim they lived together in an "zunajzakonska skupnost", and everything acquired during the relationship canbe treated the same as with marriage, and split in half (unless someone proves they contributed significantly more,...). The existance of "zunajzakonska skupnost" iz not well defined and has to be decided in court, but it can bring many many problems.

We also have only recently legalized prenups.

Oh, and living wills are very very limited too. ..so yeah...

In the United States (and presumably England) this is called "common law marriage".

I don't know if it's enough for one partner to claim marriage to the other, but if they both claim it the marriage is valid.

Here, only one has to claim it, but they have to prove it in court. Usually this is usually done by proving they lived together, bought things together, etc. and if there were other elements of a relationship.

I have no idea what happens if two non-romantic roomates buy a couch together, and one of them moves out though.

Presumably they end up on Judge Judy. More seriously, sounds like something that could be handled in small claims court if there's really a dispute about it.

It can't be handled in small claims court because the claims aren't small and exceed the limits of what a small claims court can rule on - I mean, if someone has spent 20 years in that 'common law marriage' then that generally comes to the full extent of divorce proceedings - how to divide up the house, car(s), other property and custody of children.

"It" referred to this earlier hypothetical:

> I have no idea what happens if two non-romantic roomates buy a couch together, and one of them moves out though.

I'd certainly hope the couch would fall under the $10,000 limit for small claims.

I should have been more specific. I was referring to the question about what happens when roommates buy a couch together in order to illustrate it's not quite the same.

It hasn't existed in England for quite some time. It existed in variant form in Scotland until recently.

Common-law marriage only exists in a handful of states (8 out of 50, plus DC) in the US: https://en.wikipedia.org/wiki/Common-law_marriage_in_the_Uni...

It can bring problems I'm sure, but is not having such a legal concept better? If two people build their lives together then I think they need to be explicitly about what is whose if they want legal clarity when things go wrong.
