Child Support

Both parents have a legal duty to support their children. In Washington, child support is based on the Washington Child Support Schedule. The Schedule takes into consideration the total cost of taking care of the children and providing them with a home. The Schedule also takes into consideration each parent’s respective share of that cost according to their incomes.

Child support is subject to periodic modification to address the changing needs of the children and changes in each parent’s ability to pay. Child support payments are typically required until the child's eighteenth birthday or when the child graduates from high school, whichever occurs last. Other circumstances may affect the duration of the support obligation allowing the court to terminate the parental obligation for the support.

In some cases, the parents are required to pay post-secondary support for a dependent child’s college or vocational education expenses. Special rules also apply to the support of a handicapped or disabled child.

Factors Used to Determine Child Support in Seattle, WA

Although most child support determinations are made using the standard calculations, the court can deviate from the standard calculation for several reasons, including the possession of wealth or a significant disparity in the living costs of the parents due to conditions beyond their control.

The amount of child support that will be ordered by the court depends on a variety of factors. The most important factors include:

  • How many children do the parents have together?
  • How many of those children are under 12?
  • How much is the monthly take-home pay of the person responsible for paying child support?
  • How much is the monthly take-home pay of the person who will receive child support?

Under RCW 26.19.080, a parent is obligated to pay his or her portion of child support relating to his children's reasonable and necessary health care costs;


Deviations from the Child Support Standard Calculations

When determining the amount of child support that can be awarded, the court will consider all income and resources of the parties before the court, new spouses or new domestic partners, and other adults in the households.

RCW 26.19.071(1) does not require that the court make a precise determination of income. Instead, the court is required to consider all income and resources of each parent's household.

The presumptive amount of support shall be determined according to the child support schedule. Unless specific reasons for deviation are set forth in the written findings of fact and are supported by the evidence, the court shall order each parent to pay the amount of support determined by using the standard calculation.

The court shall enter findings that specify reasons for any deviation or any denial of a party's request for any deviation from the standard calculation made by the court. The court shall not consider reasons for deviation until the court determines the standard calculation for each parent.

When reasons exist for deviation, the court shall exercise discretion in considering the extent to which the factors would affect the support obligation. The agreement of the parties is not by itself adequate reason for any deviations from the standard calculation.

RCW 26.19.075 provides a non-exclusive list of the types of wealth the court may consider. Under RCW 26.19.075(1) those reasons can include sources of income and tax planning, nonrecurring income, debt and high expenses, residential schedule, and children from other relationships.


Deviations for Sources of Income and Tax Planning

The court may deviate from the standard calculation after consideration of the following assets in determining the wealth of a parent:

  • Possession of wealth, including but not limited to savings, investments, real estate holdings and business interests, vehicles, boats, pensions, bank accounts, insurance plans, or other assets;
  • Income of a new spouse or new domestic partner, if the parent who is married to the new spouse or is in a partnership with a new domestic partner is asking for a deviation based on any other reason. Income of a new spouse or new domestic partner is not, by itself, a sufficient reason for deviation;
  • Income of other adults in the household if the parent who is living with the other adult is asking for a deviation based on any other reason. Income of the other adults in the household is not, by itself, a sufficient reason for deviation;
  • Child support actually received from other relationships;
  • Gifts;
  • Prizes;
  • Extraordinary income of a child;
  • Tax planning considerations only if the child would not receive a lesser economic benefit due to the tax planning; or
  • Income that has been excluded under *RCW 26.19.071(4)(h) if the person earning that income asks for a deviation for any other reason.

Deviations for Nonrecurring Income

The court may deviate from the standard calculation based on a finding that a particular source of income included in the calculation of the basic support obligation is not a recurring source of income. Depending on the circumstances, nonrecurring income may include overtime, contract-related benefits, bonuses, or income from second jobs.

Deviations for nonrecurring income shall be based on a review of the nonrecurring income received in the previous two calendar years.


Deviations for Debt and High Expenses

The court may deviate from the standard calculation after consideration of the following expenses:

  • Extraordinary debt not voluntarily incurred;
  • A significant disparity in the living costs of the parents due to conditions beyond their control;
  • Special needs of disabled children;
  • Special medical, educational, or psychological needs of the children; or
  • Costs incurred or anticipated to be incurred by the parents in compliance with court-ordered reunification efforts under chapter 13.34 RCW or under a voluntary placement agreement with an agency supervising the child.

Deviations Because of the Residential Schedule

The court may deviate from the standard calculation if the child spends a significant amount of time with the parent who is obligated to make a support transfer payment. The court may not deviate on that basis if the deviation will result in insufficient funds in the household receiving the support to meet the basic needs of the child or if the child is receiving temporary assistance for needy families.

When determining the amount of the deviation, the court shall consider evidence concerning the increased expenses to a parent making support transfer payments resulting from the significant amount of time spent with that parent and shall consider the decreased expenses, if any, to the party receiving the support resulting from the significant amount of time the child spends with the parent making the support transfer payment.


Deviations for Children from Other Relationships

When the court has determined that either or both parents have children from other relationships, deviations under this section shall be based on consideration of the total circumstances of both households. All child support obligations paid, received, and owed for all children shall be disclosed and considered by the court.

The court may deviate from the standard calculation when either or both of the parents before the court have children from other relationships to whom the parent owes a duty of support.

  • The child support schedule shall be applied to the mother, father, and children of the family before the court to determine the presumptive amount of support.
  • Children from other relationships shall not be counted in the number of children for purposes of determining the basic support obligation and the standard calculation.
  • When considering a deviation from the standard calculation for children from other relationships, the court may consider only other children to whom the parent owes a duty of support. The court may consider court-ordered payments of child support for children from other relationships only to the extent that the support is actually paid. 

Imputation of Income for a Voluntarily Unemployed Parent

The deviation standards under RCW 26.19.075 govern some child support determinations in Washington State. The court will use imputation of income for a voluntarily unemployed parent.

Under RCW 26.19.071(6), a court imputes income to a parent for the purpose of child support when that parent is voluntarily unemployed. RCW 26.19.071(6) states, in pertinent part:

The court shall impute income to a parent when the parent is voluntarily unemployed or voluntarily underemployed. The court shall determine whether the parent is voluntarily underemployed or voluntarily unemployed based upon that parent's work history, education, health, and age, or any other relevant factors.

Under RCW 26.19.071(6), a court imputes income at a past rate of pay where information on current or historical rates of pay is incomplete or sporadic. RCW 26.19.071(6) states, in pertinent part:

In the absence of records of a parent's actual earnings, the court shall impute a parent's income in the following order of priority:

(a) Full-time earnings at the current rate of pay;
(b) Full-time earnings at the historical rate of pay based on reliable information, such as employment security department data;
(c) Full-time earnings at a past rate of pay where information is incomplete or sporadic.[6]


Enforcing Out of State Child Support Orders in Washington State

The Uniform Interstate Family Support Act ("UIFSA") governs how Washington courts enforce child support orders issued by courts in other states. Before the UIFSA existed, parties could have competing child support orders in different states. As a result, parents could avoid obligations by moving to states with more favorable laws. The resulting litigation caused the system to be in a state of general chaos.

To fix these problems, the UIFSA established a “one-order” system where one state would have continuing, exclusive jurisdiction over a support order. To make it work, UIFSA includes several provisions relating to modifying and enforcing support orders from other states.

The first issue in these cases is determining which provision of the UIFSA choice of law statute applies. When determining which provisions of the UIFSA chose of law statute applies, the statute provides:

(1) Except as otherwise provided in subsection (4) of this section, the law of the issuing state or foreign country governs:

(a) The nature, extent, amount, and duration of current payments under a registered support order;

(b) The computation and payment of arrearages and accrual of interest on the arrearages under the support order; and

(c) The existence and satisfaction of other obligations under the support order.

(2) In a proceeding for arrears under a registered support order, the statute of limitation of this state or of the issuing state or foreign country, whichever is longer, applies,

(3) A responding tribunal of this state shall apply the procedures and remedies of this state to enforce current support and collect arrears and interest due on a support order of another state or foreign country registered in this state.

(4) After a tribunal of this or another state determines which is the controlling order and issues an order consolidating arrears, if any, a tribunal of this state shall prospectively apply the law of the state or foreign country issuing the controlling order, including its law on interest on arrears, on current and future support, and on consolidated arrears.
RCW 26.21A.515.


Wage Withhold Mechanism in Child Support Cases

A wage withholding mechanism is generally considered to be a “remedy” under RCW 26.21A.515(3). In enacting the wage withholding remedy, the legislature found that there was an urgent need for vigorous enforcement of child support. The law provided more efficient statutory remedies to supplement the other available remedies.

RCW 4.56.210(2) does not provide a procedural mechanism to enforce a child support order. Instead, it provides a durational limit on the general enforcement of an underlying judgment for child support.

Despite the Washington case law disavowing the “statute of limitation” label for RCW 4.56.210 generally, the courts will treat the section regarding child support orders as a statute of limitation for UIFSA choice of law. RCW 26.21A.905 emphasizes that in applying and construing UIFSA, consideration must be given to the need to promote uniformity of the law with respect to its subject matter among states that enact it.


Statute of Limitation for Child Support Enforcement in Washington

Under the Washington statute of limitation, the period for enforcing the arrears judgment would have expired 10 years after the child’s 18th birthday. Under RCW 4.56.210(2), the judgment would not be enforceable after that date. However, the courts have held that RCW 4.56.210(2) is a statute of limitation for UIFSA choice of law purposes.
