Marriage Annulment Time Frame in California: Deadlines by Ground

In California, you generally have four years to file for an annulment, but the clock starts on a different date depending on the ground: for fraud, four years from when you discovered the deception; for force or physical incapacity, four years from the wedding date; and for an underage marriage, four years from the day you turned 18. Two grounds have no deadline at all. Bigamy and unsound mind can be raised at any point during the spouses’ lifetimes. The annulment time frame in California matters because missing it forecloses the option entirely, leaving divorce as your only way out.¹

Why Some Grounds Have a Deadline and Others Don’t

California treats some invalid marriages as void and others as voidable, and that distinction is what drives the timing. A void marriage was never legally valid. Only two categories qualify: marriages between close blood relatives, and bigamous marriages where one spouse was already married to someone else.² Because these marriages are legally nonexistent from day one, there is no statute of limitations pressing down on you.

A voidable marriage is different. It is treated as valid until a court says otherwise. Underage marriage, unsound mind, fraud, force, and physical incapacity all fall into this category.³ If you don’t file within the required time, the marriage stays valid and the annulment door closes for good. Courts enforce these deadlines strictly. Miss the window and no judge will grant the annulment, no matter how strong the underlying facts.¹

The Deadline for Each Ground

Underage Marriage

If you were under 18 when you married, you have four years after turning 18 to file. A parent, guardian, or conservator can also file on the minor’s behalf at any time before the minor turns 18.⁴ Once four years past the 18th birthday have elapsed, the marriage is treated as fully valid and annulment is no longer available.¹

Bigamy (a Prior Existing Marriage)

A marriage entered while one spouse is still legally married to someone else is void.⁵ Either spouse in the second marriage can file for a judgment of nullity during the lifetime of the other, and the spouse from the first marriage can file at any time.¹ There is no fixed deadline.

One narrow exception matters. If your former spouse had been absent for at least five consecutive years and you had no reason to believe they were alive, or if that person was generally believed to be dead, a subsequent marriage is not automatically void. It remains valid unless and until a court annuls it after the missing spouse turns up alive.⁵

Unsound Mind

If either spouse could not understand the nature of the marriage at the time of the ceremony, whether from a cognitive disability, serious mental illness, or extreme intoxication, the marriage is voidable. There is no fixed filing deadline. The affected spouse, a relative, or a conservator can file at any time before either spouse dies.¹ But there is a catch. If the person who lacked capacity later regains understanding and voluntarily continues living with the other spouse, the right to annulment is lost.³

Fraud

When one person’s consent was obtained through deception, the defrauded spouse has four years from the date they discovered the fraud to file.¹ The discovery date, not the wedding date, starts the clock. That said, the fraud must go to something fundamental about the marriage itself. Courts have recognized claims based on concealing an inability or unwillingness to have children, hiding a serious criminal history, and marrying solely to obtain immigration status. General dishonesty about finances or personality traits usually will not qualify.

Force

A spouse whose consent was obtained through coercion has four years from the date of the marriage to file.¹ Unlike fraud, the clock here runs from the wedding, not from when the coercion ended.

Physical Incapacity

If one spouse was physically unable to consummate the marriage at the time of the wedding and that condition appears incurable, the other spouse has four years from the date of the marriage to file.¹ The California Courts self-help guide clarifies that this means an inability to have sexual relations, not simply an inability to have children.⁴ Only the unaffected spouse can bring this claim.

Being Within the Deadline Isn’t Always Enough

For fraud and force, timing is only half the battle. Even if you are still inside the four-year window, continuing to live with your spouse after the pressure lifts can destroy the claim. The statute states that a marriage cannot be annulled if the defrauded party, “afterwards, with full knowledge of the facts constituting the fraud, freely cohabited with the other as his or her spouse.” The same rule applies once coercion has ended. A court can find that you ratified the marriage by staying.³

The practical takeaway: the deadline is a ceiling, not a target. If you learn the truth about a fraud, or the coercion stops, the calendar is running against you on two fronts at once. Waiting comfortably inside four years while still living together can cost you the case even before the deadline hits.

Quick Reference: The Windows at a Glance

Underage marriage: four years after the minor turns 18. A parent, guardian, or conservator can file at any time before the minor turns 18.
Bigamy: no deadline. Either spouse in the second marriage can file during the other’s lifetime; the spouse from the first marriage can file at any time.
Unsound mind: no fixed deadline, but only before either spouse dies, and lost if the affected spouse regains capacity and freely continues living with the other.
Fraud: four years from the date the defrauded spouse discovered the deception.
Force: four years from the date of the marriage.
Physical incapacity: four years from the date of the marriage, filed by the unaffected spouse.

If the Deadline Has Already Passed

If your window has closed, the court treats your marriage as valid and annulment is off the table. Your two remaining paths are divorce and legal separation. Divorce terminates the marriage and triggers a mandatory six-month waiting period between filing and final judgment. Legal separation lets the court divide property and order support while you remain technically married. For most people who need community property protections, financial support, or a clean legal break, divorce is the more practical choice once annulment is no longer available.

One more boundary worth naming. California’s annulment rules cover the invalidation of a marriage, not the timing of a divorce or a legal separation, and the deadlines above do not apply to those cases. If you are outside the annulment window, or your situation does not fit one of the six grounds, the time limits described here simply do not govern what you file next.
