Picture this: John and Lisa walk into the courthouse for the first time with nerves jangling. They hope to end their marriage without it becoming a war. They want to keep things civil, maybe even friendly, for the sake of their family. Starting January 1, 2026, California couples like John and Lisa get a new tool in the toolbox: the Joint Petition. For those of us in mediation or collaborative law, this is a game changer. It’s a big step toward what we’ve always wanted, helping families split up without tearing each other apart. This new process is right in line with what we do every day: keeping things peaceful and focused on the people, not the fight.

Let’s be honest: every divorce in California starts as a lawsuit. The very first page of the standard Petition (FL-100) hits you with a summons that says, “You are being sued.” It’s even repeated in two languages. That kind of language might make sense if you’re gearing up for a fight, but it’s always felt out of place for those of us who believe in mediation or Collaborative Divorce. Finally, with the new joint petition, we get a form that actually fits the way we want to help families, cooperatively.

Now, don’t get me wrong, this doesn’t mean the end of courtroom battles. If you want to fight it out, the old Petition and Response are still there, with all the usual drama. But for couples who’d rather skip the mudslinging, the joint petition takes away that first unnecessary punch. It lets you start the process together, not as enemies.

A Quick Primer on the New Law for California Joint Divorce Petitions

This change comes from SB 1427, which authorized the Judicial Council to create a joint filing process for dissolution and legal separation. The new procedure for joint petitions, implemented through the Judicial Council’s new FL-700 form, becomes available for use on January 1, 2026. The revisions to the California Family Code can be found in section 2320 and related provisions.

The key points:

• The spouses file a joint petition (FL-700) if they agree to do so.
• Both parties sign the same form.
• There will be a new summons (FL-710) with no “service of process” and no adversarial caption. However, the Standard Family Law Restraining Orders still apply just like any other divorce filing. These orders automatically kick in to protect both parties by maintaining the status quo and ensuring peace during divorce proceedings, regardless of the filing method.
• Both spouses make a general appearance by signing, which means the court has jurisdiction over both parties from the start.
• The same 6-month waiting period still applies.

Why This Matters for Couples and Professionals

For families, this new form changes everything. It sets the right tone from the start, one of cooperation and respect. Now, instead of one spouse having to “sue” the other, you can file together. It’s a small shift in paperwork but a major change in energy. The joint petition says, “We’re doing this together.” That’s a big deal.

For mediators and collaborative professionals, this is a breath of fresh air. We can help clients complete one shared petition and move forward as co-petitioners. It’s a more human way to begin a hard process.

What to Know Before You File the California Joint Divorce Petition

Like any new system, the joint petition has some details to understand before jumping in:

• General Appearance
  When both spouses sign the FL-700, they’re telling the court, “We’re here, and you have power over us.” You can’t later say, “Wait, I wasn’t served properly.” Be sure both understand that before signing.
• Independent Advice
  Each spouse should have the chance to talk with an attorney before signing. Even in mediation, independent legal advice is important.
• If Cooperation Fails
  If things change and one person wants to back out, either spouse can file a Notice of Revocation of Joint Petition (FL-720). From that point on, the case moves forward like a traditional divorce. The revoking spouse must file a new Petition (FL-100) or Response (FL-120) the same day they revoke.
• No Defaults
  There’s no such thing as a default in a joint petition because the parties each are making a joint appearance when they file. Both must sign off on any amendments. If one person stops cooperating, progress can stall.
• Court Transition Period
  Courts will need time to adjust. Expect a few hiccups as clerks and e-filing systems catch up early in 2026.

When Cooperation Breaks Down: Revoking a California Joint Divorce Petition

As with any cooperative process, it does not always stay that way. Not every joint filing stays joint. The new system anticipates that a previously non-adversarial case may later become adversarial. For that, the Judicial Council created Form FL-720 (Notice of Revocation of Joint Petition).

Here’s how it works:

• Either party may revoke the joint petition at any time before the judgment is entered.
• The filing spouse must serve the other with the FL-720 and then file it with the court.
• Once filed, the joint petition is terminated. It does not simply pause or convert.
• The form itself explains that Petitioner 1 becomes the Petitioner and Petitioner 2 becomes the Respondent.

That’s where things get interesting. The FL-720 directs that a new Petition (FL-100) or Response (FL-120) must be filed at the same time as the revocation. Whoever files the FL-720 is, by default, starting or continuing the action as the Petitioner. The other party has 30 days after service of the revocation to file their corresponding pleading.

Here’s a quirky twist: if Petitioner 2 files the revocation, the first thing the court sees might be a Response instead of a Petition. The law doesn’t say you can’t do it, but it flips the usual order on its head. We’ll see how court staff handle this one.

If you or your spouse plan to revoke, file both the FL-720 and the proper initiating pleading on the same day, and carefully track the 30-day response period. If you receive a Notice of Revocation of Joint Petition, remember you have 30 days to respond.

A Step Toward a Less Adversarial System

This is a big step toward changing the culture of divorce in California. The California joint petition acknowledges what many of us have long known: not every divorce fits neatly into the “plaintiff versus defendant” box. For couples who want to stay out of the mud, this form opens a cleaner, kinder path, and gives families a better way to begin.

Of course, it’s still important to get sound legal and financial advice before signing anything. But all things considered, it’s a win for couples who want to stay out of the courtroom crossfire.
