Maybe this varies from state to state, but let's say a young chap owns a brokerage account worth 1 million dollars of various securities before his marriage. For a couple of months after his marriage, the dividends are reinvested into the same account, totaling a few hundred dollars. Then, he reconfigures his account to sweep future dividends into a community account. Does this really mean that the million-dollar account is now community property? Or, in the even of divorce, are the few hundred dollars' worth of dividends usually parsed out easily enough given that there is a clear record of them?
