Ex parte communication in a family law case is any one-sided contact with the judge about your case that happens without the other party knowing or being present. Courts prohibit it because decisions about custody, support, and property have to be made on information both sides have seen and had a chance to answer. There are two narrow exceptions, strict rules about how a judge must handle any improper contact that slips through, and real consequences for the party who tries it.
What Counts as One-Sided Contact With the Judge
The scope is broader than most people expect. Under the Model Code of Judicial Conduct, a judge cannot initiate, permit, or consider communications made outside the presence of the parties or their lawyers concerning any pending case.1American Bar Association. Rule 2.9: Ex Parte Communications That covers more than phone calls and private meetings. It includes emails to chambers, letters slipped into a case file, messages passed through a clerk, and hallway conversations at the courthouse.
It also reaches well past direct party-to-judge contact. The comments to Rule 2.9 make clear the restriction applies to communications from lawyers, law professors, and anyone else who is not a participant in the case.2American Bar Association. Comment on Rule 2.9 Having a relative, friend, or new partner reach out to the judge on your behalf is just as prohibited as doing it yourself.
In family court, the triggers are predictable. A parent furious about a missed custody exchange fires off an email to the judge. Someone writes a long letter explaining why their spouse is unfit. A grandparent calls chambers to “set the record straight.” All of these are violations, regardless of how justified the sender feels. Good intentions are not an exception.
When One-Sided Contact Is Allowed
Two narrow categories of contact are permitted. Knowing where the line sits keeps you from crossing it by accident.
Scheduling and Administrative Questions
You can contact the court about matters that have nothing to do with the substance of your case. Calling the clerk to confirm a hearing date, asking how to file a particular form, or checking which courtroom to report to is fine.1American Bar Association. Rule 2.9: Ex Parte Communications The distinction is substance. “When is my hearing?” is permissible. Adding “and I want the judge to know my ex has not been following the custody order” crosses the line.
Genuine Emergencies
A party can also seek an emergency order without the other side present when there is a risk of immediate and irreparable harm. In family law, this usually comes up with domestic violence, child abuse, or a credible threat that a parent is about to flee the jurisdiction with the children.
Emergency requests are not informal conversations. They are formal filings with specific documentation. Under Federal Rule of Civil Procedure 65, a court can issue a temporary restraining order without notice only when the requesting party presents specific facts in an affidavit or verified complaint showing that immediate and irreparable injury will occur before the other side can be heard, and the attorney certifies what efforts were made to give notice and why notice should not be required.3Legal Information Institute. Rule 65 – Injunctions and Restraining Orders State family courts use similar frameworks, typically requiring sworn declarations that lay out the factual basis for the relief.
Any order issued this way is temporary by design. Under the federal rule, a temporary restraining order expires within 14 days unless the court extends it for good cause for a similar period.3Legal Information Institute. Rule 65 – Injunctions and Restraining Orders State timelines vary, but the structure is the same: the emergency order holds the situation in place long enough to schedule a full hearing where both sides appear. The other party also has the right to move to dissolve or modify the order on short notice. An emergency order is a pause, not a final decision.
Even in a permitted emergency or administrative contact, the judge must promptly notify all other parties of the substance of what was said and give them a chance to respond.2American Bar Association. Comment on Rule 2.9 Transparency is the default.
Your Own Lawyer Is Bound by the Same Rule
The prohibition does not land only on judges and parties. If you have a lawyer, they are independently bound. Under the Model Rules of Professional Conduct, a lawyer cannot communicate ex parte with a judge or other court official during a proceeding unless authorized by law or court order.4American Bar Association. Rule 3.5: Impartiality and Decorum of the Tribunal An attorney who violates the rule faces professional discipline on top of whatever the court does in your case.
This matters because an attorney’s violation can blow back on the client. If your lawyer sends an improper message to the judge, the court may attribute that conduct to your side of the case, undermining your credibility at the exact moment the judge’s trust is everything. If you suspect your own attorney is engaging in back-channel contact, raise it immediately. It is not zealous advocacy.
What the Judge Must Do When It Happens
Judges are not passive. When a judge receives an unauthorized communication about a pending case, the Model Code of Judicial Conduct requires them to promptly notify all parties of the substance and give each party an opportunity to respond.1American Bar Association. Rule 2.9: Ex Parte Communications The obligation applies even when the judge did not invite or welcome the contact. If someone mails the judge a letter about your custody case, the judge is supposed to put it on the record and let you know what it said.
That disclosure does two things. It gives the other side a fair chance to address what was communicated, and it creates a record that can be reviewed on appeal. A judge who receives a prohibited communication and says nothing creates exactly the kind of hidden influence the rule exists to prevent.
Consequences for the Party Who Did It
Judges take violations seriously, and the penalties scale with the severity. A minor first-time violation may draw a formal warning on the record. More serious contact carries steeper consequences.
- Disclosure and response. At a minimum, the communication goes into the court record and the other party gets to respond. That alone can hurt, because it marks you as someone willing to work around the process.
- Sanctions and fees. Courts have broad authority to sanction misconduct. A judge may order the party who initiated the improper contact to pay the other side’s attorney fees incurred in addressing it. Contempt is available for flagrant or repeated violations.
- Evidence or pleadings struck. A judge can refuse to consider arguments or evidence that were tainted by the improper contact, and can strike filings influenced by it.
- Orders voided. Any order that resulted from or was influenced by the communication can be vacated and the issue reheard with both sides present.
- Judicial disqualification. In extreme cases, the contact may raise enough doubt about the judge’s impartiality that disqualification becomes necessary. Under the Model Code, a judge must step aside whenever their impartiality might reasonably be questioned. Starting over with a new judge can add months to an already slow process.5American Bar Association. Rule 2.11: Disqualification
In a custody case there is an additional practical consequence no rule needs to spell out. Judges remember who tried to go around the system. A parent who tried to privately influence the court has damaged their own credibility on the issue where it matters most, and that impression can quietly shape how the judge weighs everything else that parent says.
What to Do if You Suspect the Other Party Contacted the Judge
How you handle it matters almost as much as the violation itself. The instinct to call chambers and report what you heard is understandable, but doing that would be its own ex parte communication. Everything has to run through proper channels.
If You Have an Attorney
Tell your lawyer right away. Your attorney will know the local rules for raising the issue and will file a formal motion describing the suspected communication and asking the court for corrective action. That motion gets served on the other party, so the process stays transparent. Depending on what happened, the motion can ask for disclosure of the communication, sanctions, fee-shifting, or vacating any tainted orders.
If You Are Representing Yourself
Document what you know: dates, times, what was said, how you learned about it, and any supporting evidence. File a written motion with the court explaining the situation and requesting appropriate relief, and serve a copy on the other party. Filing fees and formatting rules vary by jurisdiction, so check with the clerk’s office. The point is to put the issue in front of the judge in writing, on the record, with notice to both sides. Do not try to handle it with a phone call or a hallway conversation, because that creates the very problem you are trying to fix.
Preserving the Record for Appeal
Whether you have a lawyer or not, make sure the issue and the court’s response are documented in the official record. If the trial court does not adequately address the violation, a clean record gives you grounds to raise it on appeal. Appellate courts take due process violations seriously, and an unremedied one-sided communication can be reason to reverse a custody or support order.
