Wierd question ya I know

So if there were two twin girls and they met these to brothers then one of the couples got married could they still get married without it being like against the law?Cause if the first two couples get married then that would make the other couple by law brother and sister. So what happens?

Pretty sure that being brother and sister in law does not present any legal problems or relation issues. Even if they were to marry they would still remain as just that, brother and sister in law.

I think the only thing that makes it sound remotely weird is the title of brother and sister.

Ya guess so ha idk its just been stewing over in my brain so I just wondered.

The other two twins wouldn't be brother and sister by law, so there isn't even an issue.

Here's an example: although, yes, my sister-in-law considers me her sister-in-law ever since she married my brother, it is because SHE married into MY family. Same applies the other way, my brother considers his wife's brother to be his brother-in-law because HE married into HER family. I obviously entered into neither of their families when they got married, so I did not gain any in-law siblings from their marriage.

The same thing applies in this situation. Although the other male twin is now the brother-in-law of the married female twin, it is only because the married female twin is now legally a part of the male twins' family. The other female twin is not part of the male twins' family and therefore is not related to them in any way.

Does this make sense? It's a very confusing thing to explain...

AAAH ok then well cool stuff thankyou ha.
