Divorce During Pregnancy

By Chad Foster, Family Law Attorney · Updated July 17, 2026

Divorce is never easy, and it can be especially complex when one spouse is pregnant. In Snohomish County, pregnancy does not prevent or delay the divorce process. Judges cannot deny or postpone a divorce solely because one spouse is expecting a child. However, pregnancy must be disclosed in the Petition for Divorce paperwork, and the court will address parentage issues as part of the proceedings. Understanding the general divorce process in Washington provides helpful context for these unique circumstances.

When the Divorce Process Has Already Started

Information and agreements regarding pregnancy and parentage may be added to the proposed divorce order at any time before finalization. Once the divorce order is signed by the judge, changes are difficult unless the order specifically allows for modifications.

Presumption of Parentage

Under Washington law, a spouse is presumed to be the legal parent of a child born during the marriage - even if not biologically related. This presumption applies even if the child is born after the divorce is finalized. To avoid unintended legal obligations, it is important to address parentage clearly in the divorce order. Courts can include rulings that disestablish parentage if appropriate.

Alternative Conception Methods

When assisted reproductive technology or sperm donation is involved, parentage may depend more on intent to parent than biological connection. Courts give significant weight to the intent of the parties, and legal options exist to establish or disestablish parentage in these circumstances.

Parenting Plans and Child Support

Parenting plans and child support orders cannot be finalized until after the child is born. However, the court may allow the divorce case number to be reused later for these orders by reserving the issue. This approach can save time and expense if parentage is established during the divorce. If the issue was not reserved, a Petition to Establish a Parenting Plan must be filed after the child's birth.
