Hum? I think CA law is that if the man breaks the engagement the woman keeps the ring, if the woman breaks the engagement she has to give it back.
They are talking about it now on KMJ. As I understand it, it doesn’t matter who breaks the engagement, the man can still get the property back because they were given in anticipation of marriage.
Not sure if it’s an actual law, but that’s been common etiquette forever. If she dumped him, he gets the ring.
