How Do Washington State Courts Decide What’s in the Best Interests of the Child?

Overview: When parents divorce or separate in Seattle and throughout Washington state, one of the biggest questions is how the court will decide where a child lives and how parenting responsibilities will be shared. Every decision begins with one guiding principle: What arrangement is in the best interests of the child and will give them the greatest opportunity to grow up in a safe, stable, and supportive environment.

Key Takeaways

• Washington state courts base parenting plan decisions on the best interests of the child.
• Judges evaluate each family’s unique circumstances rather than applying a one-size-fits-all approach.
• The strength, nature, and stability of the child’s relationship with each parent are given the greatest weight.
• Additional factors include voluntary and knowing agreements of the parties, a parent’s past performance of parenting functions and potential future performance, the emotional needs and developmental level of the child, a child’s relationship with siblings, other significant adults, school or other significant activities, and the parents’ employment schedules.
• In instances where a child is sufficiently mature, the court will take into consideration the child’s preferences along with the parents’ preferences, although that is not a guarantee the child’s or a parent’s preferences will control. Washington state courts do not favor mothers or fathers based on gender.
• An experienced Seattle family law attorney can help you present evidence that supports your child’s best interests.

What Does “Best Interests of the Child” Mean in Washington State?

When Seattle parents and parents throughout Washington state cannot agree on a parenting plan during a divorce or other family law matter, the court must determine what arrangement will best serve the child. The focus is not on what either parent wants or what feels most fair to them. Instead, the court considers a set of factors determined by the legislature and mandated by statute to determine what will best support the child’s health, emotional well-being, development, and long-term stability.

Washington state law recognizes that children generally benefit from having healthy relationships with both parents whenever it is safe and appropriate. Judges strive to create parenting plans that encourage those relationships while protecting children from situations that could place them at risk. 

Although many people in Seattle and across Washington state still use the words “child custody,” Washington family law uses the terms “parenting plans” and “residential time” instead. Among other details, a parenting plan outlines where a child will live, how parents will share decision-making responsibilities, the residential time the child spends with the respective parents, and how they will resolve disagreements in the future. Residential time refers to the schedule that delineates when the child spends time with each parent, including weekdays, weekends, holidays, school breaks, and vacations.

Factors the Court Considers When Adopting a Parenting Plan

When establishing a residential schedule, Washington state courts give the greatest weight to the strength, nature, and stability of the child’s relationship with each parent. This and other statutory factors help the court determine the specifics of a parenting plan that will best serve the child’s interests. 

Additional factors can include agreements of the parents, provided they were voluntary and knowing, the emotional needs and developmental level of the child, a child’s relationship with siblings, other significant adults, school or other significant activities, and the parents’ employment schedules.

A parent’s past performance of parenting functions and potential future performance is also important. The court wants to understand who has historically cared for the child, participated in daily routines, attended school conferences, scheduled medical appointments, helped with homework, and provided emotional support. This does not mean one parent must have done everything. Instead, the court looks at each parent’s role in the child’s life before the family law case began. 

Some of these factors are discussed in more detail below.

Does the Child Get to Choose Where to Live?

One of the most common misconceptions in Washington state family law is that children automatically get to decide where they will live once they reach a certain age. That is not how the law works.

Washington state does not establish a specific age at which a child may choose one parent over the other. Instead, the court may consider a child’s preferences if the judge believes the child is mature enough to express thoughtful and independent opinions. Thus, occasionally this may be a factor in some families’ circumstances.  Even then, those wishes are only one part of the overall analysis.

The child’s preference never controls the outcome on its own. The court will still evaluate every relevant factor to determine what arrangement serves the child’s best interests.

Why Stability Is So Important in Assessing the Best Interests of the Child

Children often adjust better when their lives remain as consistent as possible during and after a divorce. While change is unavoidable initially, Washington state courts try to minimize unnecessary disruption thereafter. 

The need for stability is why one of the factors includes how the child is doing at school, the child’s connections to friends and community activities, and whether maintaining certain routines would benefit the child’s emotional health. Stability does not necessarily mean that one parent automatically receives more residential time. Instead, it entails creating a parenting plan that provides consistency and predictability.

Every family has different circumstances. For one child, stability may mean remaining in the same school district. For another, it may involve preserving strong relationships with siblings or extended family members. The court examines the complete picture before making a decision.

Washington State Courts Look at Each Parent’s Ability to Meet the Child’s Needs

The best interests analysis goes beyond financial resources or job titles. A judge wants to know whether each parent can consistently provide for the child’s physical, emotional, educational, and developmental needs.

This includes evaluating whether a parent provides a safe home environment, supports the child’s education, addresses medical concerns, encourages healthy routines, and responds appropriately to the child’s emotional well-being. The court also considers each parent’s ability to communicate and cooperate when making important decisions affecting the child.

The goal is not to determine which parent is perfect. Instead, the court seeks a parenting arrangement that best meets each child’s unique needs.

When Can a Court Restrict a Parent’s Residential Time?

Protecting children from harm is one of the court’s highest priorities. In some situations, Washington state law requires or permits judges to place limits on a parent’s residential time or decision-making authority. 

Restrictions may be appropriate when there is credible evidence of domestic violence, child abuse, neglect, substance abuse, abandonment, a significant physical disability of a parent, serious mental health concerns that affect parenting, serious impairment of emotional ties with the child, withholding a child for a protracted period without good cause, or a documented history of abusive conflict. Depending on the circumstances, the court may require supervised visitation, limit overnight visits, prohibit contact completely, and/or restrict a parent’s authority to make major decisions for the child. 

These restrictions are based on evidence presented during the case. Allegations alone are not enough.

How Washington State Courts Create a Parenting Plan for Each Family

No two families are exactly alike, which is why no single parenting schedule works for everyone. Washington state courts evaluate each family’s circumstances individually and craft parenting plans based on the evidence presented. 

Whenever possible, judges encourage parents to reach agreements through negotiation or mediation rather than asking the court to decide every issue. Parents usually know their children better than anyone else, and parenting plans developed together are often easier to follow over the long term.

When parents cannot reach an agreement, the court carefully reviews testimony, school records, medical information, evaluations, and other evidence before entering a parenting plan designed to support the child’s best interests.

Frequently Asked Questions

What does “best interests of the child” mean in Seattle and throughout Washington state?

Best interests of the child describes the standard by which Washington state courts make parenting plan decisions. Judges consider what will best support a child’s safety, health, emotional well-being, development, and long-term stability, rather than what either parent prefers.

Do Washington state courts favor mothers over fathers?

No. Washington state law does not give preference to either parent based on gender. Judges evaluate the facts of each case and determine what parenting arrangement best serves the child.

Can my child decide which parent to live with?

 No. However, if the court determines a child is mature enough to express a reasoned and independent preference, a judge may consider that preference. There is no guarantee the child’s preference will be adopted, and there is no specific age at which a child can “choose” where to live. From a legal perspective, a person under the age of eighteen is a “child,” and the prevailing view is that the terms of a parenting plan should be determined by the adults.

What is the difference between child custody and a parenting plan?

In 1987, Washington passed the Washington State Parenting Act, which ushered in a new approach involving court orders pertaining to children in divorce and legal separation cases. Today, Washington orders  “parenting plans” and “residential schedules” instead of “custody.” A parenting plan establishes residential time, decision-making responsibilities, and procedures for resolving future disagreements.

What is residential time in Washington state?

Residential time is the schedule that determines when a child lives with or spends time with each parent. A Washington state parenting plan establishes residential time for regular weekdays and weekends as well as holidays, school breaks, and vacations.

Can a parenting plan be modified after a divorce in Washington state?

Only in specific circumstances. Once a parenting plan is adopted by the court, subsequent modification of it is presumed to be disruptive and not in the children’s best interests. Parenting plans may only be modified when the legal requirements under Washington state law are met. For this reason, the parenting plan that is adopted by the court in a divorce or legal separation should be carefully thought out. 

What happens if domestic violence is involved?

A court may limit or supervise a parent’s residential time or decision-making authority if the evidence supports restrictions under Washington state law.

Do most parenting plan cases go to trial?

No. Many parents in Seattle and across Washington state resolve parenting issues through negotiation or mediation. If they cannot reach an agreement, the court will decide the parenting plan based on the evidence and the child’s best interests.
