When a trust dispute finally settles, everyone breathes a sigh of relief. The case is over, the lawyers can move on, and the family can begin to heal. But sometimes, one party doesn’t follow through. What if someone refuses to pay, transfer assets, or carry out their part of the deal?
These situations are more common than you might think. The good news is that California law gives you strong tools to enforce settlement terms without restarting the entire case. Under Code of Civil Procedure Section 664.6, the court can step back in to make sure both sides honor the agreement—saving you time, money, and frustration.
What Makes a Settlement Enforceable in California?
Before we talk about enforcement, let’s start with the basics. Not every agreement between parties counts as a legally enforceable settlement. Under California law, certain requirements must be met before a court can step in to enforce the deal.
Written and Signed by All Parties
A valid settlement must be in writing and signed by all parties involved. Handshake deals or informal email exchanges are not enough.
In trust litigation under the Probate Code, this rule is even stricter: the parties themselves must sign the settlement agreement. Under Code of Civil Procedure Section 664.6(c), attorneys cannot sign on behalf of their clients in Probate Code actions.
Clear Intent to Settle
The agreement must show that the parties intended to fully resolve the dispute. It should clearly identify what claims or issues are being settled—whether that’s a fiduciary duty claim, a distribution dispute, or a disagreement over trust interpretation.
Knowing and Voluntary Consent
Each party must have understood and voluntarily agreed to the settlement. Courts will consider whether the parties had time to review the agreement, had legal representation, and were not pressured or misled. In family-based trust disputes, this helps ensure the agreement reflects genuine consent rather than coercion or emotional pressure.
Using Code of Civil Procedure Section 664.6 to Enforce a Settlement
California Code of Civil Procedure Section 664.6 gives parties a streamlined way to enforce settlements without starting a new lawsuit. Instead of re-litigating the entire dispute, you can file a simple motion in the same case asking the court to enforce the terms of your agreement.
How It Works
Section 664.6 allows the court to retain jurisdiction to enforce a settlement if the parties either:
- Include a request for court retention of jurisdiction in a written agreement signed by all parties, or
- Make that request orally before the court.
In trust litigation under the Probate Code, the parties themselves—not their attorneys—must sign the settlement and any request for the court to retain jurisdiction. This requirement is strict and cannot be waived.
Why It’s Helpful
When the court retains jurisdiction, enforcement becomes far simpler. If one side fails to comply, the other can file a motion to enforce rather than starting from scratch. The judge can order compliance, enter judgment for unpaid amounts, or even impose sanctions for contempt if necessary.
Faster, Cheaper, and More Direct
Because the court already has authority over the case, this process moves quickly. There’s no need for new pleadings, discovery, or trial preparation. You’re simply asking the judge to make sure both sides follow through on the deal they already agreed to.
When Written Settlements Aren’t Available
Sometimes parties reach a settlement before a formal written agreement is signed. California law accounts for this by allowing settlements made orally before the court to be enforced under Section 664.6.
Oral Settlements Can Still Be Enforced. If the settlement was stated on the record in front of a judge, such as during trial or mediation, it can still be binding. However, enforcement requires stronger proof. The court must be satisfied that all material terms were agreed upon and that both sides clearly intended to settle. Testimony from attorneys, witnesses, or other evidence may be needed to confirm what was said.
While an oral settlement can be enforced, a written agreement remains the best way to avoid future disputes about what was actually agreed to.
What Happens When One Party Won’t Comply
Even with a signed settlement and court jurisdiction under Section 664.6, one side might still refuse to perform.
Filing a Motion to Enforce. The non-breaching party can file a motion explaining which terms were violated, including evidence such as missed payments or unreturned assets.
What the Court Can Do. The judge may
- Order immediate compliance
- Enter judgment for unpaid amounts
- Require asset transfers
- Impose sanctions or hold the party in contempt if the violation is willful
Types of Settlements Covered. Enforcement applies to all types of trust settlements, including:
- Monetary payments where courts can issue judgments and allow collection through standard methods such as wage garnishment or bank levies.
- Property or asset transfers where the court can compel the transfer or impose penalties if someone refuses to comply.
- Ongoing trustee obligations such as making regular distributions or providing accountings, which the court can monitor through future compliance hearings.
In complex or highly emotional family disputes, courts may issue detailed orders or appoint a neutral third party, such as a mediator or special master, to ensure compliance and reduce future conflict.
Procedural Requirements You Can’t Ignore
To enforce a settlement, you must follow California’s procedural rules. You can’t simply show up in court and demand compliance. Courts require specific steps to be followed before they’ll act.
Filing in the Right Court
File your motion to enforce in the same court where the original case was pending, as long as the court retained jurisdiction under Section 664.6.
If the case was dismissed without jurisdiction, you’ll need to file a separate action to enforce the settlement, which is more time-consuming and costly. This is why having Section 664.6 language or a court order retaining jurisdiction at the time of settlement is so important.
Proper Service
You must properly serve the other party with notice of your motion and copies of all supporting documents. Email alone is not sufficient. Service generally requires a process server or service through the opposing attorney. If service is done incorrectly, the court may refuse to hear your motion.
Supporting Evidence
Your motion should include a declaration from you or your attorney explaining what was agreed upon and how the other side failed to comply. Attach the signed settlement agreement and any relevant communications, such as emails or letters showing repeated requests for compliance. Courts want clear evidence of both the agreement and the breach.
Be Ready to Testify
If the other party disputes your motion, the judge may want to hear brief testimony. You should be prepared to explain what the settlement required, what steps you took to secure compliance, and how the breach has affected you. Your attorney can help organize and present this evidence effectively.
When the Regular Settlement Process Fails
Sometimes, even with the Section 664.6 process, a party still refuses to follow court orders. If someone ignores a payment judgment or refuses to transfer property, you may have additional remedies beyond standard compliance orders.
Contempt of Court
Contempt applies when someone willfully violates a clear court order. It is a serious remedy, but courts use it when other measures fail.
- Civil contempt penalties may include fines of up to $1,000 and imprisonment of up to five days for each violation. Courts may also award attorney fees and costs to the party who initiated the contempt action.
- Criminal contempt penalties apply in more severe cases, such as repeated violations of protective orders in elder abuse or domestic violence situations. Penalties can include up to one year in county jail for misdemeanors or sixteen months, two years, or three years in state prison for felonies.
Courts usually reserve contempt for willful disobedience, but it can be an effective tool when someone ignores the court’s authority.
Attorney Fees and Costs
If your settlement agreement includes a clause for attorney fees or if California law allows it, the court may order the non-complying party to pay your enforcement costs. Many settlements include a “prevailing party” provision to make sure you are reimbursed if enforcement becomes necessary.
Additional Remedies
If someone hides assets or transfers property in violation of the settlement, you may pursue contempt, seek attorney fees, or file additional claims for fraud or related misconduct. An experienced attorney can help assess which remedy will be most effective in your situation.
Making Sure Your Settlement Actually Sticks
The best way to avoid enforcement problems is to prevent them from happening in the first place. By taking a few smart steps when you settle, you can make future enforcement much easier if it ever becomes necessary.
Draft a Clear, Detailed Agreement
Your settlement agreement should be specific and unambiguous. Spell out exactly what each party must do and when they must do it. Vague language invites disputes later because the other side can claim they misunderstood what was required.
Include Section 664.6 Language
Always include Section 664.6 language asking the court to retain jurisdiction to enforce the settlement. This single step gives you access to California’s streamlined enforcement process.
Without it, you may have to file a new lawsuit to enforce the deal. In trust litigation, both the parties themselves—not just their attorneys—must sign the settlement and any request for the court to retain jurisdiction.
Specify Clear Deadlines
Every obligation should have a clear deadline. Instead of saying “the defendant will pay the plaintiff,” say “the defendant will pay the plaintiff $5,000 within 30 days of court approval.” This leaves no room for interpretation.
Build in Monitoring Mechanisms
If the settlement involves ongoing duties, include a system to monitor compliance. For example, a trustee could provide quarterly accountings to beneficiaries or submit reports confirming distributions. Regular updates create a record of compliance and help catch issues early.
Ensure True Agreement
Finally, make sure everyone genuinely agrees before signing. In family trust disputes, emotions often run high, and parties sometimes sign just to end the conflict. That approach rarely works. Judges enforce settlements as written, so it’s far better to confirm that all sides truly understand and accept the terms before signing.

Frequently Asked Questions
What if we settled our trust dispute but didn’t include Section 664.6 language?
Without Section 664.6 language or a court order retaining jurisdiction, the court cannot easily enforce your settlement. If a breach occurs later, you will likely need to file a new lawsuit. Always include Section 664.6 language in future settlements.
Can a judge jail someone for not following settlement terms?
Yes, but only in extreme cases. Courts can hold someone in contempt for willfully disobeying a clear court order. Penalties can include fines or short jail time, although this is a last resort.
What if someone says they did not understand the settlement agreement?
Courts generally assume adults understand what they sign. To challenge validity, a person must show they lacked a fair chance to review the agreement or were misled, not just that they regret signing it.
How long do I have to enforce a settlement?
It depends on the terms. One-time payments are enforced quickly, while ongoing duties can be enforced as long as they remain due. Time alone does not void enforcement rights. Speak with an attorney about your situation.
What if the other party cannot perform their part of the deal?
If performance truly becomes impossible, the court may adjust or excuse obligations. But if someone simply refuses to comply, the court can enforce the original settlement.
Can an attorney sign the settlement agreement for their client?
Not in trust or probate cases. Under California law, the parties themselves—not just their attorneys—must sign the settlement agreement and any request for the court to retain jurisdiction. Attorney signatures alone are not enough for enforcement under Section 664.6.
Can settlements reached in mediation be enforced under Section 664.6?
Yes, but only if the agreement is signed by the parties and clearly states that it is enforceable under Section 664.6. Confidential mediation discussions are not enforceable unless a final, signed settlement agreement is created.
