The State of Washington has unique laws when it comes to divorce proceedings. To start with, one of the spouses must be a resident of the State or work with the armed forces and stationed here. The filing of the divorce petition is normally done in the county the spouse filing for divorce resides. This petition is not acted upon by the court until 90 days have elapsed from the day the filing process and summoning took place. Before going ahead to file for a divorce, you are advised to first agree with your spouse that this is what both of you want. This will save you a lot of time and unnecessary paperwork.
When you have both agreed, this is called an uncontested divorce where both of you agree on the divorce, how to divide property and agree on the custody of the children if any. You therefore go ahead and file for a no fault grounds dissolution of marriage where it is generally assumed that there is no fault found for deciding to divorce. Here, the only ground for the dissolution process to take place is irretrievable breakdown of the marriage. If the summoned party disagrees with the fact that the marriage has broken down irreversibly, the court goes ahead and investigates the reasons as to what may have led to the filing of the divorce petition. If it finds enough evidence to support the allegation, it shall dismiss the petition.
When the couple cannot come to terms on how to divide property they have, the court does this regardless of whose fault it was in the marriage breakdown. The only property that is shared is the one you have both acquired together. This is shared equally without touching on any other individually acquired properties that may be there. Spouse support is determined on case by case basis but child support is given great emphasis first. This the court goes to great lengths in determining how to go about it.
