Quick answer

A Marital Settlement Agreement (MSA) is a legally binding contract between you and your spouse that outlines exactly how you will divide your property, handle child custody, and pay support. When attached to your final Judgment (FL-180), the judge signs it, making the terms of your agreement an enforceable court order.

If you want an uncontested divorce in California — meaning you want to avoid a trial and keep your costs down — you need a Marital Settlement Agreement. For the complete list of California divorce forms, see our master checklist.

Commonly called an MSA, this document is the ultimate goal of the divorce process. It is a comprehensive contract that resolves every single legal issue between you and your spouse.

Why You Need an MSA

When you file for divorce, the court has jurisdiction over your marriage, your property, and your children. If you cannot agree on how to handle those things, a judge will decide for you at a trial. Trials are incredibly expensive, public, and unpredictable.

An MSA allows you to bypass the judge. It tells the court, "We have figured this out ourselves. Here is our contract."

What Must Be Included in the MSA?

1. Property and Debt Division

California is a community property state. The MSA must explicitly state who gets the house, who keeps which cars, how the retirement accounts are split, and who is responsible for paying off the credit card debt. Vague language like "Wife gets the bank accounts" will be rejected by the court — list specific account numbers and addresses.

2. Child Custody and Visitation

If you have minor children, the MSA must detail your parenting plan — legal custody (decision-making power), physical custody (where the child lives), and a specific visitation schedule including holidays and summer vacations.

3. Child Support

The MSA must address child support. You can agree to the guideline amount calculated by the state formula, or you can agree to a non-guideline amount with specific legal language explaining why the different amount is in the best interest of the child.

4. Spousal Support (Alimony)

The MSA must clearly state whether one spouse will pay the other, the exact dollar amount, the frequency of payments, and exactly when the payments will end. If both spouses agree to waive spousal support forever, the MSA must include a strict waiver clause terminating the court's jurisdiction over the issue.

The Legal Power of the MSA

Once the judge signs the Judgment (FL-180) with your MSA attached, the MSA becomes a court order. If your spouse agrees in the MSA to pay off a specific credit card and then fails to do so, they are in contempt of court.

Because the MSA is so powerful, you cannot sign it until both spouses have completed their mandatory financial disclosures — the Schedule of Assets and Debts (FL-142) and the Income and Expense Declaration (FL-150). You cannot legally agree to divide property until you both have a full, transparent picture of what exists to be divided.

Frequently asked questions

Is an MSA a specific court form?

No. Unlike the FL-100 or FL-150, there is no official, fill-in-the-blank court form for an MSA. It is a custom-drafted legal document. While some courts provide templates, most people use a document preparation service or an attorney to draft the MSA to ensure the legal language is correct.

Do we have to sign the MSA in front of a notary?

Yes. In California, the signatures on a Marital Settlement Agreement must be notarized. This proves to the court that neither spouse forged the other's signature.

What comes after the MSA?

After both spouses sign and notarize the MSA, you attach it to your final judgment packet (FL-130, FL-170, FL-180) and submit it to the court. See our guide on what happens after you file the Petition for the full timeline.
