At Northwest Family Law, child support cases are about protecting your child’s stability and your peace of mind. 

Our attorneys combine deep knowledge of Washington’s RCW 26.19 child support laws with an empathetic, hands-on approach that keeps you informed and supported at every step. If you’re seeking to establish, modify, or enforce a child support order, we help you handle the process with clarity and confidence.

The average child support obligation for one child in King County can vary depending on combined parental income. Getting that figure right and making sure it reflects your true financial circumstances requires precision, legal insight, and a strong advocate on your side.

Clients describe their experience with Northwest Family Law as “clear, communicative, and compassionate.” One recent review shared:

“I was always kept informed of every update, even after business hours. They genuinely cared about my case and my family.”

That’s the standard we uphold. Every parent we represent receives personalized guidance and the assurance that their child’s best interests come first.

When you work with our Seattle child support lawyers, you gain a dedicated partner committed to securing fair, lasting solutions that help your family move forward with stability and confidence.

Understanding Child Support and Why It Matters in Seattle

Child support is a legal obligation under Washington law (RCW 26.19) requiring both parents to financially contribute to a child’s well-being, to cover essentials like housing, food, clothing, and shared child expenses.

In Seattle and King County, child support matters deeply because it bridges the gap between divorce or separation and confirming a child’s stability amid change. The goal is to preserve the child’s standard of living, even though their parents no longer live together.

Key Features in Washington’s Child Support: 

  • Economic Table & Presumptive Amounts. Washington uses a published economic table to set a baseline “basic support obligation” per child, tied to the combined net incomes of both parents.
  • Allocation by Income Share. The amount derived from the table is allocated between parents based on their income proportion.
  • Deviations Allowed. Courts may adjust the baseline (higher or lower) if strict application would be unfair, for example, when one parent has significant parenting time or the child has special needs.
  • Modification Threshold. If circumstances shift, job loss, income change, medical needs, either party can petition for modification if the new amount differs by at least 15 % from the existing order.

Why It Matters in Seattle

Seattle’s high cost of living, especially for housing, childcare, and education, makes equitable child support a necessity.

Fair payment calculations help custodial parents maintain stability, while also making sure non-custodial parents aren’t overburdened. With the city’s rising expenses, properly structured support orders can make the difference between a child’s consistent care and financial strain on both households.

An experienced Seattle child support attorney helps confirm that calculations are accurate, modifications reflect real financial changes, and enforcement actions are pursued when payments lapse, all with the goal of protecting the child’s best interests in a city where every dollar matters.

About Northwest Family Law

Since opening in 2014, Northwest Family Law has focused on one goal, helping families rebuild with clarity, compassion, and strength. The firm was created to provide more than legal representation. Every client receives steady guidance, transparent communication, and genuine care at every stage of their case.

Our attorneys understand that family law issues reach far beyond court filings. Divorce, child custody, and support decisions shape lives for years to come. That is why we listen first, act with empathy, and pursue solutions that protect both immediate needs and long-term stability.

Each attorney brings deep experience in Washington family law and is licensed to practice before the King County Superior Court and neighboring jurisdictions. The team regularly works with local mediators, financial planners, and mental health professionals to support clients through every aspect of transition. 

Our Child Support Process in Seattle

At Northwest Family Law, we guide Seattle parents through a clear, step-by-step process that protects your rights and keeps you informed from start to finish. 

Step 1: Consultation & Case Assessment

We start with a focused, confidential consultation, often the same week you reach out. Here, your attorney reviews your current parenting plan, income information, and goals. You’ll leave this first meeting with a clear understanding of how Washington’s RCW 26.19 applies to your situation and what realistic outcomes look like.

Step 2: Calculation & Filing

Next, we prepare your Child Support Worksheet using Washington’s state formula and local King County deviations. Accuracy here is everything, small details in income, tax deductions, or daycare expenses can change monthly support by hundreds of dollars. 

Once reviewed, we file with the King County Superior Court electronically or in person, depending on urgency.

Step 3: Negotiation or Mediation

When both parents can agree, we pursue mediation to settle support amounts efficiently and privately. This often happens near the Seattle City Hall mediation offices or virtually for convenience. Our attorneys make sure any agreement meets state requirements and fully protects your financial interests before it’s signed.

Step 4: Order & Enforcement

After court approval, the order becomes enforceable through Washington DSHS or direct payroll withholding. If the other parent fails to comply, our team acts quickly, requesting enforcement through the Family Support Division of the King County Prosecutor’s Office or filing a motion for contempt when necessary.

Step 5: Ongoing Review & Modification

Life changes, so can your order. We review existing support arrangements when income shifts, parenting time changes, or new expenses arise. Modifications are often resolved without a hearing, keeping stress and costs low. 

Child Support Timelines in Seattle

Most Seattle child support cases resolve in about 2 to 6 months when both parents cooperate and disclosure is complete. Disputed or intricate cases (such as self-employment income, relocation, or modification hearings) can extend to over a year.

Because our office is located close to the King County Courthouse and Seattle City Hall, we can file motions and respond to court requests quickly, helping avoid unnecessary delays.

Local Insight That Saves You Time

King County’s electronic filing and hearing systems are efficient but nuanced. Because our attorneys regularly appear before Seattle-area family law commissioners, we know how to present calculations and deviations effectively, often saving clients weeks of waiting time.

Client Testimonials

I originally reached out to Northwest Family Law because they had a mostly female team. When I scheduled my consult, their first available was with a male attorney. I would be lying if I said I wasn’t a little nervous to meet with him after having met with other male attorneys in the community. I waited 3 weeks to have our consultation and I was immediately blown away. He showed genuine concern for myself and my son, he was well versed in the information I had left with the receptionist when I scheduled the consult and very much put me at ease with moving forward in pursuing dissolution of marriage.

My team consisted of Mitchell and Cydney primarily with some help from Nikki as well. Mitchell and Cydney are amazing, so thorough, responsive, helpful, informative and kind. I’m so glad they were on my team, they are so very competent and really care about their clients. My husband’s attorney left a lot to be desired and was the complete opposite of this team so I’m very thankful I found Northwest Family Law. Huge thank you to Mitchell, Cydney and Nikki for taking care of me throughout the dissolution process! Me, my son and our dog are all living our best lives thanks to you all 💜
