Preparing for a Custody Hearing in Washington: Declarations, Working Papers, and What Judges Actually Read

Here is the single most important thing to understand about a Washington custody hearing: the judge has probably already formed a preliminary view of your case before you say a word. That is because Washington Superior Court commissioners and judges decide family law motions primarily based on the written declarations submitted before the hearing — not on what you say at the podium.

If your written submission is weak, disorganized, or emotional, a strong oral presentation rarely saves it. If your declarations are clear, factual, and well-supported, the hearing itself is often a short confirmation of what the paperwork already established.

What a Declaration Is and Why It Matters

A declaration is a written statement submitted under penalty of perjury. In Washington family law, you use Form FL All Family 135 (Declaration) to present your version of the facts to the court. It serves the same function as testimony — the judge treats it as sworn evidence.

Your declaration is not a letter to the judge explaining how you feel. It is an evidentiary document. Every sentence should state a specific, observable fact. Compare these two approaches:

Weak: "The other parent is irresponsible and doesn't care about our child's education."

Strong: "On September 12, 2025, the child missed school because the other parent did not wake them in time for the bus. The school attendance record, attached as Exhibit A, shows seven unexcused absences during the other parent's residential time between August and November 2025."

The second version gives the judge something to evaluate. The first gives the judge nothing except your opinion.

How to Structure Your Declaration

A well-organized declaration follows a logical structure that mirrors the court's analytical framework:

Opening paragraph — state who you are, your relationship to the child, and what you are asking the court to do. Keep this to two or three sentences.

Background section — briefly describe the family structure, the child's age, and the current living arrangements. Do not relitigate the entire history of the relationship.

The facts supporting your request — this is the core of the document. Organize by topic (residential schedule, decision-making, safety concerns) rather than chronologically. For each point, provide specific dates, names, and supporting evidence.

Exhibits — attach supporting documents and reference them in the text. School records, medical records, text message screenshots, police reports, and photographs all carry more weight than your characterization of events.

Conclusion — restate what you are asking for in one or two sentences.

Working Papers: The Package That Goes to the Judge

In most Washington counties, the commissioner or judge receives a set of "working papers" — the complete packet of documents filed by both sides — before the hearing. The exact filing deadlines and requirements vary by county:

King County LFLR 6 requires motions to be filed at least 14 calendar days before the hearing. Responses are due by noon 5 judicial days before. Replies are due by noon 3 judicial days before.

Spokane County operates on a similar schedule but with county-specific deadlines set by local rule.

Snohomish County uses its own local scheduling rules.

Missing a filing deadline can mean the judge never sees your declaration. Some courts will refuse to consider late-filed documents entirely. Others will accept them but give them reduced weight. In either case, late filing signals disorganization — not the impression you want to make.

What Judges Look For

Washington judges evaluating custody motions apply the best interests factors under RCW 26.09.187. Your declaration should address the factors that are most relevant to your situation:

• The child's relationship with each parent — the relative strength, nature, and stability of those relationships. This factor receives the greatest weight by statute under RCW 26.09.187(3)(a).
• Historical caregiving — which parent has been primarily responsible for daily parenting functions like meals, bedtime routines, homework help, medical appointments, and school communication.
• Stability and continuity — how the proposed schedule affects the child's connections to their school, neighborhood, friends, and extended family.
• Each parent's ability to encourage the child's relationship with the other parent — judges watch for evidence that one parent is undermining or obstructing the other's involvement.
• Safety concerns — any documented history of domestic violence, substance abuse, or neglect that would trigger restrictions under RCW 26.09.191.

You do not need to address every factor. Focus on the two or three that are strongest for your case and present concrete evidence for each.

Common Mistakes That Hurt Your Case

Writing too much. A 20-page declaration about a temporary orders hearing is counterproductive. Judges have limited time. Keep temporary orders declarations to 3-5 pages. Trial declarations can be longer, but every paragraph should earn its place.

Attacking the other parent's character. Judges distinguish between relevant facts and personal grievances. "They were unfaithful" is irrelevant to custody unless it directly affected the child. "They left the child unsupervised for six hours on March 3" is relevant.

Making unsupported claims. If you cannot attach evidence for a factual assertion, consider whether to include it. Unsupported claims can undermine the credibility of your well-documented points.

Ignoring the other parent's strengths. A declaration that acknowledges the other parent's positive qualities and involvement — while explaining why your proposed schedule still serves the child's best interests — reads as balanced and credible. A declaration that portrays the other parent as entirely incompetent reads as adversarial.

Practical Hearing Day Tips

Arrive early. Dress professionally. Bring a complete copy of everything you filed — do not assume the judge has your documents in front of them.

When the commissioner or judge asks you questions, answer directly. Do not use your speaking time to re-read your declaration aloud. The judge already read it. Use your time to respond to the other side's arguments or to highlight the most critical evidence.

If the hearing is conducted via Zoom (common in King County and several other counties), test your technology beforehand. Log in from a quiet location. Position the camera at eye level. Treat it with the same formality as an in-person appearance.

How the Guide Helps

The Washington Child Custody & Parenting Plan Guide includes a declaration builder worksheet that walks you through the FL All Family 135 form section by section. It helps you organize your facts by topic, identify which exhibits to attach, and structure your argument around the statutory best-interests factors — turning your personal knowledge into a professional, court-ready submission.
