Your spouse says they won’t agree to a divorce. Maybe they said it outright. Maybe they just refuse to engage. Either way, you need to know something: in California, you do not need their permission.

California is a no-fault state. The law does not require both spouses to agree that the marriage is over. One person can decide, and that decision is enough.

Here is how the law actually works, and what your options look like when the other side won’t cooperate.

The Two Grounds for Divorce in California

The California Family Code (§2310) recognizes two grounds for divorce: irreconcilable differences and permanent legal incapacity to make decisions.

Nearly every divorce in California is filed under irreconcilable differences. The statute defines that term broadly. Under California Family Code §2311, irreconcilable differences are “substantial reasons for not continuing the marriage” that make it appear the marriage should be dissolved. The law does not require you to list specific complaints. It does not ask you to prove fault. Under Family Code §2335, evidence of specific acts of misconduct, including infidelity or abuse, is inadmissible in a dissolution proceeding.

The second ground, permanent legal incapacity, requires competent medical or psychiatric testimony that the other spouse permanently lacks the capacity to make decisions (Family Code §2312). This ground is rarely used. If you are reading this post, irreconcilable differences is almost certainly the basis for your case.

Your Spouse Cannot Block the Divorce

This is the part that matters most to people in your situation.

Once you file a petition citing irreconcilable differences, the other spouse cannot successfully contest it. The California Court of Appeal addressed this directly in In re Marriage of Greenway (2013). The court held that the decision that a marriage is irretrievably broken does not need to be based on objective facts. The code does not require proof that both parties agree. It requires the court to find substantial reasons for not continuing the marriage.

In practice, the standard is even simpler than the case law suggests. In over 23 years of family law work, I have never seen a court deny a dissolution when one party wanted out. It takes one person to get a divorce in California. The court will not sustain objections to a plea of irreconcilable differences.

Your spouse can refuse to participate. They can refuse to sign papers. They can refuse to show up. None of that stops the process.

What Actually Happens When Your Spouse Won’t Cooperate

The court process still moves forward. Here is what it looks like in practice.

You file a petition for dissolution with the court, citing irreconcilable differences. You then have your spouse served with the papers. Service puts them on legal notice that the case is open.

If your spouse does not respond within 30 days, you can request a default. A default means the court can proceed without their participation. You submit your proposed judgment, and the court reviews it. If your spouse never engages, the court can enter the judgment based on what you have presented.

If your spouse does respond but remains difficult, the case proceeds through the normal litigation track. The court will schedule hearings. It will make orders. Your spouse’s refusal to cooperate may slow things down, but it will not stop the divorce from happening.

The minimum timeline in California is six months from the date of service. That clock runs whether or not your spouse participates.

There Is a Better Way to Do This

The court process works. But it is expensive, slow, and adversarial by design. If there is any possibility of getting your spouse to the table, mediation or collaborative divorce will usually produce a better outcome for both of you.

Mediation

In mediation, a neutral mediator sits with both of you and works through the issues: property division, support, custody, parenting plans. The mediator does not make decisions for you. The mediator helps you have the conversation and reach your own agreement.

This matters in your situation for a specific reason. A spouse who says “I won’t grant you a divorce” is often really saying “I am not ready” or “I feel like I have no control over this.” Mediation gives that person a seat at the table. It gives them a role in shaping what happens next. That shift, from feeling powerless to having a say in the outcome, often changes the entire dynamic.

Mediation is private. Nothing said in the room becomes part of the public record. The solutions can be tailored to your family in ways a court order cannot. And the cost is typically a fraction of litigation.

Collaborative Divorce

In collaborative divorce, each spouse has their own attorney, but both sides commit at the outset to reaching a settlement without going to court. The attorneys work together rather than against each other. Financial specialists and divorce coaches can be brought in as needed.

The commitment to stay out of court is what gives collaborative divorce its structure. Everyone at the table has agreed to solve the problem, not fight about it. For a reluctant spouse, this can feel safer than litigation. They are not being dragged into a courtroom. They are being invited into a process where they have real participation and real representation.

Both mediation and collaborative divorce are built to handle the emotional difficulty that comes with ending a marriage. Trained professionals manage the hard conversations. That matters when one spouse did not want this.

The Bottom Line

You do not need your spouse’s agreement to get a divorce in California. The law is clear on that point, and the courts enforce it consistently.

The only real question is how you get through the process. You can litigate, and the court will eventually grant the divorce whether your spouse cooperates or not. Or you can try mediation or collaborative divorce, which may bring your spouse into the process voluntarily and produce an outcome that works better for everyone.
