Family Laws in Washington.

The sole ground for divorce in Washington is that the marriage is "irretrievably broken." No fault-based grounds exist.

Washington is a community property state. The court divides property "justly and equitably" considering the nature and extent of community and separate property, duration of marriage, and economic circumstances. "Equitable" does not necessarily mean equal.

Washington uses "parenting plans" rather than custody orders. The court considers best interest factors with greatest weight given to the strength, nature, and stability of the child's relationship with each parent. Other factors include parental agreements, parenting performance, emotional needs, sibling relationships, and the child's wishes.

Washington uses the income shares model. Combined monthly net income of both parents is mapped to an economic table. Minimum $50/child/month. Neither parent's obligation may exceed 45% of net income without good cause.

The court considers financial resources, time needed for education/training, standard of living during marriage, duration, age/health/financial obligations, and ability to pay. A 2024 WA Supreme Court ruling confirmed that financial "need" is not a prerequisite for an award.
