I think a motion for him to leave the house is a little harsh. I think Washington lawyers are bitches.
Ok now that I have that out Have the sherrif serve him. It will be a harsh reality, but if you want my advice don't listen to your greedy lawyer. You are in for a long drawn out fight that will exhaust you. If you husband is as you say he will not go down with a fight. He will lose after all this is Washington and they hate men here, but the more he hesitates the more the lawyers make and the less you make. You are in for some serious trama I don't think you have any idea. Your lawyer will pump you up with stuff that is over exagerated. You will be better to do some footwork (not on here but real law books) yourself.
Good luck but I think you are in for some real entertainment. You really have no idea. I would spend some time and read some posts here. That will give you a better idea of what you are up against.
