Family Law & Divorce Services in Washington – Compassionate Advocacy
Understanding Family Law in Washington
Family law in Washington covers divorce, child custody, spousal support, property division, De Facto Parentage, Family Member Visitation, and more. As a community property state, Washington requires that most marital assets be divided equitably, and divorces must observe a minimum 90-day waiting period after filing. At Tresa A. Sadler PLLC, our attorneys help families in Mill Creek, Snohomish County, King County, and beyond navigate these rules with clarity and confidence.
