Absolutely. Heres one fucked up example. You thought of an idea; get married; divorced; you implement the idea/make money off it;. Goodluck cause now state gets to decide how much ip-right/money should the ex-spouse get.
Citation? Everything I'm reading says that your property, including IP, that was exclusively yours before marriage, is yours when you get divorced. Likewise, I don't see any way for post-divorce ideas and businesses to be considered "community property". Looking at WA laws though.
