Does Washington use the term 'custody'?

Washington's statute centers on the parenting plan rather than a 'custody' award. Every divorce, legal separation, or paternity case involving minor children requires a court-approved permanent parenting plan covering the residential schedule and decision-making authority, rather than a single custody label.

Is there a presumption of equal residential time in Washington?

No. Washington law contains no gender-based presumptions and no automatic presumption favoring a 50/50 residential schedule. Both parents start from the same position and have to show the court their proposed schedule serves the child's best interest.

What factors does Washington weigh?

RCW 26.09.187 lists seven factors, with the greatest weight given to the strength and stability of the child's relationship with each parent. Other factors include each parent's past and potential future performance of parenting functions, the child's emotional needs, the child's relationships with siblings and other significant people, the child's wishes if of sufficient age and maturity, each parent's employment schedule, and each parent's ability to foster the child's relationship with the other parent.

How much notice do I need to relocate with my child in Washington?

If the move is outside the child's current school district, the relocating parent must give the other parent written notice at least 60 days before the move, by personal service or certified mail. If moving within the same school district, actual notice by any reasonable means is enough, and the other parent can't object to an in-district move.

Can the other parent object to a relocation?

Yes, if the move is outside the child's school district. The non-relocating parent can file an objection, which generally triggers a court review of whether the move should be allowed and how the residential schedule should be adjusted. Failing to give required notice can lead to fines or other sanctions, including contempt.

How is child support calculated in Washington?

Under the Washington State Child Support Schedule (chapter 26.19 RCW), using both parents' combined net income matched to a statutory economic table. Every child support order in Washington requires a completed worksheet using this schedule.

Washington Child Custody: A Parent's Guide

How child custody works in Washington state, in plain English: the mandatory permanent parenting plan, the seven best-interest factors, relocation notice, and child support.

Last reviewed: 2026-08-09

In short: Washington centers custody around a mandatory, court-approved permanent parenting plan, covering the residential schedule and each parent's decision-making authority, rather than a single "custody" award. There's no gender-based presumption and no automatic presumption favoring an even residential split; courts weigh seven statutory factors, with the greatest weight on the strength and stability of the child's relationship with each parent. Relocating outside the child's school district requires 60 days' written notice and can be objected to by the other parent.

What Washington generally provides

RCW 26.09.187 requires a court-approved permanent parenting plan in every case involving minor children, divorce, legal separation, or paternity. Washington law uses the best interest of the child as the sole legal standard, applying seven statutory factors with the greatest weight given to the strength and stability of the child's existing relationship with each parent. There's no gender-based presumption and no automatic presumption favoring a 50/50 residential schedule, both parents have to demonstrate their proposed schedule serves the child.

Important terminology

Permanent parenting plan: the court-approved document that functions as Washington's custody order, covering the residential schedule and decision-making authority. Required in every case with minor children.
Residential schedule: the part of the parenting plan specifying where the child lives day to day, including regular weekly time, school breaks, holidays, and vacations.
Decision-making authority: allocation of authority over education, health care, and religious upbringing, decided separately from the residential schedule.
Relocation: a change of the child's principal residence, governed by its own notice and objection process under RCW 26.09.430 and following.

How custody works in Washington

The parenting plan replaces a single custody award

Rather than awarding "custody" to one parent, Washington courts approve a permanent parenting plan that specifies the residential schedule (regular weekly time, school breaks, holidays, birthdays, vacations, and special occasions) and each parent's decision-making authority over major categories, in one integrated document.

The seven best-interest factors

RCW 26.09.187 directs courts to weigh: the strength and stability of the child's relationship with each parent (given the greatest weight), each parent's past and potential future performance of parenting functions, each parent's agreements about parenting arrangements, the child's emotional needs and developmental level, the child's relationships with siblings and other significant people, the child's own wishes if of sufficient age and maturity, and each parent's employment schedule. No single factor besides the first is automatically decisive.

Building the residential schedule

Because Washington requires an integrated parenting plan rather than a generic custody label, families use it to lay out patterns like 2-2-3 or week on, week off directly within the plan's residential schedule section. See what is a parenting plan for what a strong plan generally covers regardless of jurisdiction, how to choose a custody schedule for a general framework, and the custody schedule generator to build the actual calendar.

Moving with your child (relocation)

Washington's relocation statute (RCW 26.09.430 and following) applies to a parent who has the child a majority of the time, or substantially equal time. If the move is outside the child's current school district, that parent must give the other parent written notice, by personal service or certified mail with return receipt, at least 60 days before the move (or within 5 days of learning about it, if 60 days wasn't possible). The other parent can then object, which generally triggers court review. If the move is within the same school district, actual notice by any reasonable means is sufficient, and the other parent can't object to it. Notice can be delayed up to 21 days in specific safety-related circumstances, such as entering a domestic violence shelter. Failing to give required notice can lead to fines or other sanctions, including contempt. See moving to another state with shared custody for how notice requirements and relocation standards tend to work more broadly across states.

Common questions

How is child support calculated? Under the Washington State Child Support Schedule (chapter 26.19 RCW), both parents' combined net income is matched to a statutory economic table. A completed worksheet using this schedule is required in every child support proceeding in the state.

Can a parenting plan be changed later? Yes, generally on a showing of a substantial change in circumstances, though Washington applies a somewhat higher bar to changing the residential schedule specifically (as opposed to minor adjustments) to encourage stability.

What if my co-parent won't follow the parenting plan? You can file a motion for contempt with the court. Repeated violations can lead to makeup residential time or, in serious cases, a modification of the plan itself.

Practical considerations

Because Washington's relocation process turns specifically on whether a move crosses the child's current school district, it's worth confirming which side of that line a planned move falls on before assuming notice or objection rights apply (or don't). Whatever the parenting plan specifies, the operational part that follows it, keeping both households aligned on the same schedule, logging change requests instead of relying on memory, and keeping a record if an enforcement issue arises, is a separate, ongoing piece worth planning for.
