回複：請大家幫忙，弟妹紅杏出牆，要離婚

depending on what state he's in. some states has community property law, any thing before marriage, inherritance, etc is individual property, any income occurred during marriage is half-half. If this is the case, she only get half the income less expense during the marriage at most.

For the kid, don't assume she has a big card to play. Your brother need a good lawyer to fight for him.
