Legal Question in Family Law in Washington

You do not say whether you are paying or receiving child support, and it's not safe for me to assume you are not the one with whom your kids live most of the time, just because you are the father. If you are the one paying, then you might be able to get a small reduction in your child support if you have another child, depending on how long it has been since the last child support order was entered, and other factors. If you are the one receiving support, you cannot get an increase in support by having another child with your new wife. Hope that helps.
