My sister is trying to divorce her husband and he is in the Air Force. They have been married for 3 years but they have been together for 6 and he is has been the primary father figure for her eight year old son. He put legal separation paperwork in before leaving the state for a few weeks, in that time he had changed the direct deposit from their joint account to another and left her no money for herself and her son to live on and also took her wedding/engagement rings from her purse. Now he's back and she is trying to withdraw joinder and petition for immediate dissolution of marriage. She took his laptop until he gives the rings back but he took her dogs and is now trying to kick her out of the house they had on base. He wants her to pay half of his bills (several thousands) and he will not give her any more than 300 dollars to live off per month. Is he taking advantage of her, or is all this within his legal rights?

It is a break up and divorce, one side moves out and stops paying or giving the other side anything.
** that is how this divorce things normally workds

So she goes to court, files for divorce, lists everything she wants from him, dogs, rings, and so on, Then he replys and does the same,

If she wants support for a limited time, she files for that also.

He has no obligation to give her anything,

They are both playing silly childish games at this point

Okay, what about child support? She's already collecting from biological parent, but this person actually wants to be in the child's life. I'm not sure, but I don't think you can collect child support from more than one person for the same child, can you? In the state of Washington.

In the military if only one of the members is in the military collecting housing or BAH a large sum of that has to be provided to the spouse, or on post housing has to be given to the spouse. In my recent divorce I had to pay my ex until the divorce was final, I had to pay over half of my BAH. If you talk to anyone in the military, BAH is for the spouse. The military member would not be collecting that if it were not for the spouse, so therefore the BAH is to support the spouse. As far as the child goes, if he did not adopt that child he has no legal bind. He may have been there for that child by biologically and legally he has no responsibility to the child.
