Seattle Family Law FAQs

Last updated March 7, 2026 // Attorney reviewed by Sara Kim

You just found divorce papers on the kitchen counter. Or maybe you received a parenting plan proposal that ignores everything your children need. Either way, you have questions about timelines, costs, custody standards, and what happens to the house and the retirement accounts. The answers depend on Washington law, your county’s procedures, and the specific facts of your situation. These Seattle family law FAQs answer common questions the attorneys at Blair & Kim hear from clients in King, Pierce, and Snohomish counties. We also have individual pages dedicated to Washington divorce FAQs, custody FAQs, and support FAQs.

What Are the Grounds for Divorce in Washington State?

Washington allows divorce based only on irretrievable breakdown of the marriage. Under RCW 26.09.030, one spouse simply needs to allege marriage is irretrievably broken. The other spouse does not need to agree, and the court does not require evidence of wrongdoing such as adultery or abandonment.

This means you cannot prevent a divorce by refusing to participate. If one party files and maintains that the marriage is irretrievably broken, the court will enter a decree. What you can contest are the terms: property division, custody arrangements, and support obligations.

How Long Does a Divorce Take in Washington?

The minimum timeline for any Washington divorce is 90 days after the petition is filed and served, per RCW 26.09.030. This applies even if both spouses agree on every issue. In practice, an uncontested divorce in King County typically takes three to four months from filing to final decree.

Contested divorces take significantly longer. Cases involving disputes over property, parenting plans, or spousal maintenance can take 12 to 18 months or more, depending on court availability and asset complexity.

How Is Property Divided in a Washington Divorce?

Washington courts divide all community property and debts in a “just and equitable” manner under RCW 26.09.080, which does not necessarily mean a 50/50 split. The court may also consider each spouse’s separate property when making this determination.

Community property generally includes all assets and debts acquired during the marriage, regardless of whose name is on the title. Separate property includes assets owned before the marriage, inheritances, and gifts made specifically to one spouse. However, separate property can become commingled with community property over time—for example, if inheritance funds are deposited into a joint account and mixed with other community funds or earnings. The family law attorneys at Blair & Kim in Seattle regularly handle property division disputes involving retirement accounts, real estate, and business interests across King County.

How Does Washington Determine Child Custody?

Washington courts establish a “parenting plan” instead of a custody order. Under RCW 26.09.184, the plan allocates decision-making authority and sets a residential schedule based on the best interests of the child as defined in RCW 26.09.187.

Factors the court considers include each parent’s involvement in the child’s daily care, emotional ties between the child and each parent, the child’s adjustment to home and school, and any history of domestic violence or substance abuse. Washington courts do not automatically favor one parent over the other based on gender. If parents cannot agree on a parenting plan, and failing settlement at mediation, the court will impose one after trial. This is one of the most common Seattle family law questions Blair & Kim’s attorneys address.

How Is Child Support Calculated in Washington?

Child support in Washington is calculated using the formula set forth in RCW Chapter 26.19. Each parent’s monthly net income is combined, and the court references the economic table in RCW 26.19.020 to find the base support obligation for the number and ages of the children.

Each parent’s share is proportional to their percentage of the combined income. Additional expenses—health insurance, daycare, education, transportation for visitation which are considered extraordinary expenses—are divided proportionally on top of the base amount. Courts may deviate from the standard calculation for reasons outlined in RCW 26.19.075, such as special needs of the child or significant residential time with both parents. The minimum support amount is $50 per child per month.

What Is Spousal Maintenance and Who Qualifies?

Spousal maintenance is a court-ordered payment from one spouse to the other, determined by factors listed in RCW 26.09.090: each spouse’s financial resources, time needed for education or training, the standard of living during the marriage, duration of marriage, and each spouse’s age and health.

Washington has no formula for calculating maintenance. Unlike child support, there is no economic table. The amount and duration are largely discretionary, making attorney advocacy particularly important. Short marriages rarely result in long-term maintenance, while marriages lasting 25 years or more are more likely to involve extended awards. Blair & Kim’s family law practice represents clients seeking and defending against maintenance claims in Seattle, Bellevue, and across King County.

Can I Modify a Child Support or Custody Order After It Is Entered?

Yes, both child support and parenting plans can be modified when a substantial change in circumstances has occurred. For child support, modification is often granted when either parent’s income has changed significantly. Under RCW 26.09.170, courts may allow modification when circumstances support it, including situations where a support order has been in place for a period of time and a recalculation would materially change the amount.

Parenting plan modifications require a higher threshold. Under RCW 26.09.260, the requesting party must show substantially changed circumstances and that modification serves the child’s best interests. Reasons for a major modification (change in custody or significant change in residential time) are deviations from the parenting plan, e.g., the child lives primarily in the other parent’s home; the child’s current home is detrimental to child’s wellbeing; a parent has violated the parenting plan; conviction for custodial interference; relocation.  Parents sometimes seek minor adjustments to the parenting plan for expansion of residential time, or change in schedule that no longer is workable because of the change in the parent’s or child’s schedule

Do I Need a Lawyer for a Divorce in Washington?

No, Washington does not require an attorney for a divorce. Even in  uncontested divorces with no children and minimal assets we have assisted clients to finalize the divorce after they filed on their own because understanding the procedures and navigating the court system requires time and effort.A family law attorney becomes critical when the divorce involves contested custody, significant property, retirement accounts, or domestic violence.

Mistakes in divorce paperwork can have long-lasting consequences that are difficult to fix after the decree is entered. Even if your family law questions seem straightforward, an attorney can identify issues you may not anticipate. Sara Kim, co-founding partner at Blair & Kim, has handled hundreds of divorce cases in King County since 1995 and offers flat-fee arrangements for uncontested divorces.

What Happens to the Family Home in a Divorce?

In most cases, the family home is divided as part of the overall property settlement under RCW 26.09.080. Common outcomes include one spouse buying out the other’s interest, selling the home and splitting the proceeds, or awarding the home to one spouse and offsetting the value with other assets.

When children are involved, courts sometimes allow the custodial parent to remain in the home until the youngest child reaches a certain age, at which point the home is sold. The court weighs each spouse’s ability to afford the mortgage, the children’s stability, and whether keeping the home creates a lopsided division of other assets.

What Is a Parenting Plan and What Does It Include?

A parenting plan is a mandatory court order in every Washington case involving minor children. Under RCW 26.09.184, it must address three categories: a residential schedule, decision-making authority for education, healthcare, and religious upbringing, and a dispute resolution process for future disagreements.

Parents can negotiate and submit an agreed parenting plan, or the court can impose one after a contested hearing. The plan also addresses holidays, school breaks, and transportation. If domestic violence concerns exist under RCW 26.09.191, the court may require supervised visitation or restrict decision-making authority.

Can Domestic Violence Affect the Outcome of a Divorce or Custody Case?

Yes. A documented history of domestic violence often leads to significant restrictions on the abusive parent’s custody and residential time. RCW 26.09.191 establishes grounds for the court to limit contact, require completion of a DV treatment program, or order supervised visitation, depending on the facts of the case.

Domestic violence can affect parenting plans most directly, and it may also influence other orders depending on the facts and the evidence presented. Because these cases often involve simultaneous criminal charges, criminal DV proceedings, and family law proceedings, working with a firm that handles both criminal defense and family law—as Blair & Kim does— helps coordinate strategy across both matters.

How Much Does a Divorce Cost in Washington?

A Washington divorce costs anywhere from a few hundred dollars (filing fees only, no attorney) to tens of thousands of dollars for a fully contested case. The filing fee for a dissolution in King County Superior Court is currently in the range of $300 to $350; check the King County Superior Court clerk’s fee schedule for the exact current amount. Serving the other party and any attorney fees add to the total.

An uncontested divorce with a flat-fee arrangement may cost a few thousand dollars total. A contested case with custody disputes and expert witnesses can run into tens of thousands. Blair & Kim offers flat-fee and alternative-fee arrangements for uncontested divorces, making costs predictable for qualifying clients.

What Is the Difference Between Legal Separation and Divorce in Washington?

A legal separation in Washington produces the same court orders as a divorce (property division, parenting plan, support), but the marriage remains legally intact. Either spouse may convert a legal separation into a dissolution after six (6) months have passed after the final legal separation order has been entered. The distinction between legal separation and divorce is among the most common Washington family law questions. Some clients choose legal separation for religious reasons, to maintain health insurance benefits, to continue to file joint tax returns, or when they are not yet certain about divorce. The process, timelines, and court requirements under RCW 26.09 are otherwise the same.

Can I Relocate With My Child After a Divorce?

A parent with primary residential time who intends to relocate must provide written notice to the other parent at least 60 days in advance under RCW 26.09.440. The other parent can object, and the court will then evaluate whether the move serves the child’s best interests. Relocation disputes are among the most contested family law matters in Washington, and the outcome depends heavily on the specific facts and the existing parenting plan.

What Happens If the Other Parent Violates the Parenting Plan?

A parent who is denied court-ordered residential time can file a motion for contempt in the county where the parenting plan was entered. Under RCW 26.09.160, the court may impose sanctions, award make-up time, modify the plan, and order the violating parent to pay attorney fees. Repeated or serious violations can affect future custody decisions.

What Is a Temporary Order in a Washington Divorce?

A temporary order sets the rules both spouses must follow while the divorce is pending. Under RCW 26.09.060, the court can issue temporary orders for child support, spousal maintenance, use of the family home, debt payments, and a temporary parenting plan. These orders remain in effect until the final decree is entered or the court modifies them. In King County, temporary order hearings are often scheduled within weeks of filing, but timing depends on the court’s calendar and the issues in dispute.

How Do Protection Orders Work During a Divorce or Custody Case?

Protection orders and family law cases frequently overlap, especially in domestic violence situations. A domestic violence protection order (DVPO) can be filed separately from the divorce under RCW Chapter 7.105, and the resulting restrictions on contact and residential access often affect parenting plan negotiations. In some cases, the divorce court can issue its own restraining orders under RCW 26.09.060. Blair & Kim’s attorneys handle both civil protection orders and family law proceedings in Seattle and Bellevue, which allows the firm to coordinate strategy when these cases run in parallel.

What Is the Difference Between Enforcement and Modification of a Court Order?

Enforcement asks the court to compel compliance with an existing order, while modification asks the court to change the order’s terms. If the other parent is ignoring the parenting plan or failing to pay support, the appropriate remedy is usually an enforcement motion (contempt under RCW 26.09.160) rather than a modification. When a parent voluntarily chooses not to exercise the residential time for one year or longer the court may modify the parenting plan rather than force the other parent to visit with the child.  A modification requires proof that circumstances have substantially changed since the last order. Choosing the wrong motion can delay your case and waste resources, so understanding this distinction is essential to any family law FAQ about post-decree disputes.

What Should I Do First If I Am Considering a Divorce?

Start by gathering financial documents: tax returns, pay stubs, bank and retirement account statements. A clear picture of the marital estate protects you during property division. If there are safety concerns, seek a protection order first.

Next, consult with a family law attorney to understand the likely timeline, costs, and outcomes for your situation. The family law team at Blair & Kim, including Sara Kim and Travis Moeller, handles divorce, custody, and support cases from offices in Seattle and Bellevue.

How Blair & Kim Handles Family Law Cases

Sara Kim, who has practiced family law in Washington since 1995, seeks resolution outside of court when possible but is prepared to litigate when negotiation fails.

For cases involving domestic violence, Blair & Kim’s dual criminal defense and family law capability provides a distinct advantage. When a client faces both criminal DV charges and a contested custody proceeding, the firm coordinates strategy across both matters whether you are the parent seeking to protect the child from the offending parent or the parent facing criminal DV charge that will have an impact on parenting orders. This is particularly important in King County, where criminal no-contact orders can conflict with family court parenting schedules.
