The procedure in Washington is to file a summons and petition for dissolution with the clerk of the superior court in the county where you reside. He will need to be served with the documents and the action then proceeds towards trial or settlement. The steps will be different in each county, e.g. in King County you are assigned a trial date (approximately 11 months away) at the time of filing while in other counties you have to request a trial date. At the time of filing, a party may want to have temporary relief until the time of trial or settlement, e.g. temporary use of the residence, temporary child support, attorney fees, restraining orders to prevent the disposition of assets, etc. The above will get you started to get your life back. Almost all attorneys will request a retainer to be deposited in their trust account for fees and costs. The amount will depend on what you want to have done and what might be the reaction of your spouse.
