A judge may order your ex to pay you money or give you property. If your ex does not follow the court order, you have options. You can read the law about this at RCW (Revised Code of Washington), Chapters 6 and 7. Talk to a lawyer about your unique case. What follows is a general description.
Garnishment - You can use garnishment to enforce a money judgment. The judge orders a third party with control of money belonging to the debtor (your ex) to turn that money over to the creditor (you). Example: You get an order saying your ex's employer must turn over part of your ex's wages to you.
Execution and lien foreclosure against real estate – You get a court order for the sheriff to collect on (execute) your money judgment. The sheriff seizes your ex's property and sells it to pay your judgment. Your ex should get notice before this happens. The sheriff may not seize certain types of "exempt" property.

*Your child support order and final divorce order should include a judgment for any amount owed at the time of the order. If you need a new judgment to update what is due you, have a lawyer draft the paperwork.
Replevin - to get a specific item of property (not real estate) the judge awarded you. You may also be able to file a motion for contempt. Read Getting Your Stuff Back to learn more about the replevin process.
Unlawful Detainer (eviction) - If your ex refuses to move out from (refuses to vacate) real property the court awarded you, this process forces the ex to move. You also may get money damages.
Injunction - This court order can stop someone from doing things that you don't want them to do. You can use it to keep an ex with control of property you both own from harming or wasting the property.
Receivership – The judge can appoint a "receiver" to manage or to get rid of property. The receiver does not act for either spouse.
Contempt – You cannot use contempt to force payment of a general money judgment. You can use it to get child support or maintenance. In a very few cases, you can use contempt if your ex does not do what the judge ordered them to do.
Commissioner Signature - A court commissioner can sign (execute) a document when your ex refuses to follow a court order to do something. Example: the judge ordered your house sold. Your ex refuses to sign the necessary documents.
