How can you annul a marriage in Washington?

Understanding Annulment in Washington State

Annulment is a legal process that declares a marriage null and void. Unlike divorce, which ends a valid marriage, an annulment asserts that, for specific reasons, the marriage was not legally valid from the start. In Washington State, the laws governing annulment are found under the Revised Code of Washington (RCW) 26.09.040.

Grounds for Annulment in Washington

To have a marriage annulled in Washington, you must provide evidence for one of several grounds. These include:

An example of annulment on the grounds of incompetence might involve a situation where one party was intoxicated or suffering from a mental health crisis during the wedding ceremony.

The Process of Annulment

To begin the annulment process in Washington, you must file a petition for annulment in the Superior Court. This petition should detail the reasons why your marriage is invalid and provide evidence to support your claim. It's advisable to consult with an attorney who can help navigate the legal intricacies involved.

The court will review your case and if it agrees that one of the grounds for annulment has been met, it will issue an annulment decree. This legal document officially declares that your marriage never legally existed.

Historical Context

An example from history is the annulment of Henry VIII’s marriage to Catherine of Aragon, which famously led to England’s break with the Catholic Church. This was due to her inability to produce a male heir and Henry VIII's desire to marry Anne Boleyn. Although this is an extreme historical reference, it highlights how annulments have been used in considerations of succession and legitimacy.


In summary, while divorce terminates a legally valid marriage, annulment in Washington State treats the marriage as if it never existed due to specific invalidating conditions. Successfully petitioning for an annulment requires navigating complex legal processes and proving that your marriage meets one of the set grounds for invalidity.
