When parents end a long-term relationship or marriage, they must make a series of critical decisions that clearly define the roles and responsibilities of each parent. In Washington state, child custody orders are referred to as parenting plans. As parents negotiate the terms of the parenting plan, they will need to determine living arrangements for the child (i.e., with whom the child will reside the majority of the time, how transitions between the parents’ homes will be handled, how holidays will be spent, etc.). Additionally, the parenting plan will address how decisions about the child’s education, healthcare, religious upbringing, and extracurricular activities will be made, as well as how the parents plan to resolve any disputes that may arise. Essentially, the parenting plan serves as a legally enforceable document that protects the child’s best interests and allows the child sufficient opportunities to enjoy meaningful relationships with each parent.
Once a parenting plan has been developed, a Washington judge will sign it. This means that it becomes a court order and that the terms are legally binding and enforceable. If a parent violates the terms of the existing parenting plan, the other parent can take action and notify the court of these issues. However, when one parent relocates to another state, several questions can arise about enforcing a parenting plan across state lines. It’s important to recognize that the Uniform Child-Custody Jurisdiction and Enforcement Act (UCCJEA) allows parenting plans and custody orders to be enforced out-of-state. Whether you are looking to enforce a Washington parenting plan in another state or you have a custody order from another state that you wish to be enforced in Washington, partnering with a highly qualified and caring Seattle child custody attorney is the best way for you to explore your options and identify the most strategic path forward. Let’s take a closer look at interstate custody enforcement in Washington, the role of the UCCJEA in enforcing parenting plans across state lines, and the benefits of enlisting the guidance of an established and trusted Seattle family law firm for the customized support you deserve.
Approved in 1997, the UCCJEA “requires State courts to enforce valid child-custody and visitation determinations made by sister State courts. It also establishes innovative interstate enforcement procedures.” This Act prioritizes the child’s “home state” (i.e., the state in which the child has lived for at least six months), giving this state the authority to establish or modify custody orders. The child’s home state in which the court has issued the initial, valid child custody order retains jurisdiction over these matters, even if the child relocates to another state. This allows a parent that still resides in the home state to petition for custody in the event that the other parent violates the terms of the parenting plan by abducting the child and relocating them to another state without notifying the parent or the court. The UCCJEA also provides a clear and streamlined process for registering and enforcing custody orders from out of state in order to prevent a parent from taking the child to a different state for a new custody order with more favorable terms. If you have questions about handling an issue involving cross-border custody in Washington state, consider enlisting the guidance of an experienced and knowledgeable Seattle family law attorney.
When one parent relocates to a different state and violates the terms of an existing Washington parenting plan, the other parent can file a request with the court to enforce the custody order. These situations can become challenging and confusing, so it’s often helpful to seek the guidance of an experienced Seattle child custody lawyer who can provide you with the trusted support you need. The enforcement action will depend on where the child is located. For instance, if the child’s other parent is located in a different state and the child is spending time with them at the time of the parenting plan violation, you can file a certified copy of the Washington custody order with the other state’s Family Court. Next, you will need to serve the other parent with notice of the registration. If the other parent wishes to contest this action, they have a window (usually 20 days) in which to respond. Once the registration process is complete, you may file for contempt or ask the out-of-state court to enforce the terms of the existing order.

If you need to enforce the terms of an existing child custody order from another state in the state of Washington, there are specific steps you can take to accomplish this goal. First, you will need to file a certified copy of the out-of-state custody order with your nearest Superior Court. You will also be required to complete and file several documents with the Clerk’s office, including the following:
The other parent has 20 days to request a hearing in order to contest your request to register the out-of-state custody order. If the other parent continues to violate the terms of the existing order, you can file a Petition to Enforce Out-of-State Custody Order and request the Washington court to enforce the terms of the order. Since these cases can be somewhat confusing, especially for parents wondering about jurisdictional considerations, it’s highly recommended that you seek the services of a top Seattle child custody attorney to ensure that your child’s best interests are sufficiently protected at every opportunity.
The UCCJEA establishes uniform procedures for handling emergency custody concerns and instances of parental abduction. Additionally, RCW 26.27.231 grants Washington courts temporary emergency jurisdiction in cases where the child is present in Washington state and faces abuse, neglect, or imminent harm. For example, if a parent took a child across state lines into Washington state to escape an abusive situation, Washington can assume temporary emergency jurisdiction—even if there is an existing custody order in another state. The court’s priority is to protect the safety and best interests of the child, so it can assume temporary emergency jurisdiction until the larger child custody disputes have been resolved. If you are seeking to escape with your child from an abusive partner or living environment, reach out to a trusted and caring Seattle family law attorney as soon as possible.
Although you are not required to hire legal counsel to assist you with interstate custody enforcement in Washington, taking this step is highly recommended. Disputes involving the safety of your child can be particularly stressful and emotional, so relying on a trusted legal advocate to represent the best interests of you and your child can give you the reassurance you need during this challenging and confusing time. It can be difficult to figure out which state has jurisdiction over your child custody order, and this confusion can lead to significant delays and prolonged timelines until the matter is resolved. With a skilled and knowledgeable Seattle child custody attorney by your side, you can secure the answers you need to move through the interstate custody enforcement process more efficiently and effectively.

Yes, as long as you complete the necessary paperwork. You will need to file copies of the existing Washington state custody order, notify the other parent of the registration, and petition the out-of-state court to enforce the terms of the order once it has been registered.
Washington state law requires that a parent looking to move out of state while still retaining custody of the child must provide at least 60 days notice of this move to the other parent. You have the right to object to the move and request a hearing to make your case before a judge.
If your ex moves to another state without notifying you, you can file for a temporary order that prevents the child from leaving the state. To learn more about temporary emergency jurisdiction, reach out to a trusted and experienced Seattle family law firm today.
