Washington Divorce Laws Overview

Property Division

Washington is a community property state. This means that most assets and debts acquired during the marriage are owned equally by both spouses and are typically divided 50/50 in a divorce. Assets owned before the marriage, or received as gifts or inheritance during the marriage, are generally considered separate property and are not subject to division.

Spousal Support (Alimony)

Washington judges have broad discretion in setting alimony awards. There is no statutory formula. Courts weigh a set of statutory factors including: length of the marriage, standard of living during the marriage, each spouse's earning capacity, financial resources of each spouse. This means outcomes can vary significantly depending on the judge and the specific facts of your case.

Child Support

Washington uses the Income Shares Model for child support. Both parents' gross incomes are combined, the total support obligation is determined from a guideline table, and each parent's share is proportional to their share of the combined income. The paying parent pays their share to the receiving parent.

Custody and Parenting Time

Washington courts determine custody based on the best interests of the child. While there is no statutory presumption of equal time, courts generally favor arrangements that allow both parents meaningful involvement in the child's life.
