If you inherit money while married do you split in in a divorce ?

This is not a yes or no question. If the inheritance is kept separate by the spouse who inherits it (not commingled with marital funds, like in a joint bank account), they have a decent argument NOT to split it, especially if it was inherited around the time of the divorce. If commingled, it is likely to be split. Depends on a lot of things, including how large the inheritance was and how many other assets there are. Good Luck.
