How to Write a Letter to a Judge: Template, Filing, and Service

A letter to a judge should be written as a formal business letter, addressed to “The Honorable [Full Name],” filed through the court clerk rather than sent to chambers, and served on every other party in the case. Knowing how to write a letter to a judge is partly a matter of format and partly a matter of knowing when a letter is even the right tool, because most situations that feel like they call for one actually require a formal motion.

When a Letter Is the Right Tool

The default rule across the legal system is that you cannot communicate with a judge outside of court without the other parties present or aware. This is the prohibition on ex parte communication. Under the ABA Model Code of Judicial Conduct, a judge cannot initiate, allow, or consider communications made outside the presence of the other parties or their lawyers about any pending or upcoming case.¹

Narrow exceptions exist. Courts generally allow ex parte contact for scheduling, administrative, or emergency purposes as long as the communication does not address anything substantive, no party gains a tactical advantage, and the judge promptly notifies all other parties of what was communicated.¹ A letter asking for more time to file might be acceptable. A letter arguing the merits of your case is not.

The situations where a letter to the court is appropriate are limited:

Procedural requests. Federal courts generally respond to procedural requests made by letter, such as asking for more time to file a document.²
Character reference letters before sentencing in criminal cases.
A letter the judge has specifically directed a self-represented party to submit.

Whether the judge responds at all is entirely at the judge’s discretion.² If your request involves anything substantive, such as dismissing a claim, excluding evidence, or compelling the other side to do something, you need to file a formal motion. Courts routinely ignore letters that try to bypass that process.

What the Letter Must Contain

Every letter filed with a court needs certain identifying information so it reaches the right judge and the right case file. Missing details can get the letter ignored.

At a minimum, include:

Your full legal name, mailing address, phone number, and email address.
The full name of the court where the case is pending, for example, “United States District Court for the Eastern District of Virginia” or “Superior Court of [County], [State].”
The judge’s full name with the proper form of address: “The Honorable [Full Name].”
The case name, for example, “Smith v. Jones” or “United States v. Johnson.”
The case number, also called the docket number or file number.
A clear statement of what you are requesting or the purpose of the letter.

Redact Sensitive Information

Federal courts require you to redact certain sensitive information from any document you file. Under Federal Rule of Civil Procedure 5.2, if your filing contains any of the following, you may only include partial information:³

Social Security or taxpayer ID numbers: last four digits only.
Dates of birth: year only.
Names of minors: initials only.
Financial account numbers: last four digits only.

Filing a document with these identifiers unredacted waives the protection for your own information.³ Court filings often become part of the public record. State courts have similar rules, though specific requirements vary.

Format and a Template You Can Adapt

Use a standard business letter format. Keep the letter to one page when possible. Use a readable font, standard margins, and left-aligned text. A clean layout helps staff route the letter correctly and signals that you take the process seriously.

[Your Full Name]
[Your Street Address]
[City, State, ZIP Code]
[Phone Number]
[Email Address]

[Date]

The Honorable [Judge’s Full Name]
[Name of the Court]
[Court’s Mailing Address]
[City, State, ZIP Code]

Re: [Case Name], Case No. [Case Number]

Dear Judge [Last Name]:

My name is [Your Full Name], and I am [the defendant / the plaintiff / a self-represented party / writing on behalf of (Name)] in the above-referenced matter. I am writing to respectfully request [state your specific request, such as “an extension of time to respond to the motion filed on (date)” or “that the court consider the following information before sentencing”].

[In the body, provide the relevant facts briefly and factually. If requesting more time, explain why you need it and propose a new date. If submitting a character letter, describe your relationship to the defendant and your observations. Do not argue the merits of the case, use emotional language, or make demands.]

[If applicable: I have served a copy of this letter on all parties, as reflected in the attached Certificate of Service.]

Respectfully submitted,

[Handwritten Signature]
[Typed Full Name]

The subject line is easy to overlook but matters. It is the first thing a clerk reads when deciding where your letter goes. Always include both the case name and case number on the “Re:” line.

Filing the Letter With the Court

File your letter through the court clerk’s office rather than sending it to the judge’s personal chambers. Unless a judge has specifically told you otherwise, the clerk’s office is the proper channel. The clerk logs every document into the official case file, which creates a record that the letter was received.⁴

Many federal courts now require or strongly prefer electronic filing through the Case Management/Electronic Case Filing (CM/ECF) system. Self-represented parties can request permission to file electronically by submitting a motion and registration form to the clerk’s office.⁵ Where paper filing is allowed, you can deliver the letter in person or send it by mail to the clerk’s office. Emailing a document to the court does not count as filing unless the court has specifically authorized it.⁴

Serving the Other Parties

Any document you file with the court must also be delivered to every other party in the case. This requirement is called service. Under the Federal Rules of Civil Procedure, written motions, notices, and similar papers must be served on every party.⁶

If the other side has a lawyer, serve the lawyer rather than the party directly. Acceptable methods include handing the document to the person, mailing it to their last known address, or sending it electronically if they have consented to electronic service.⁶

You also need to prove to the court that you served everyone. When you are not filing through the court’s electronic system, include a Certificate of Service with your letter. This is a short statement, filed alongside the letter, confirming that you sent copies to all necessary parties, listing their names and addresses, and stating the date and method of delivery.⁶ If you file electronically through the court’s system, a separate Certificate of Service is not required because the system notifies all registered parties automatically.

Make at least three copies before sending anything: one for the court, one for your own records, and one for each opposing party or their attorney. Certified mail with a return receipt gives you proof of delivery, though regular first-class mail is typically sufficient for service under the rules.

Writing a Character Reference Letter for Sentencing

Character reference letters are the one situation where people who are not parties to the case routinely write to a judge. They are submitted before sentencing in criminal cases and give the judge a fuller picture of who the defendant is beyond the charges. Send your letter to the defendant’s attorney, not directly to the judge. The attorney will file it properly.⁷

What to Include

Identify yourself at the start: your name, your occupation, and how you know the defendant. Explain the length and depth of your relationship. A letter from someone who has known the defendant for 20 years and can describe specific moments of character carries far more weight than a vague endorsement from an acquaintance.⁷

Include specific examples and stories. Judges read dozens of these letters, and the ones that stand out describe real moments rather than offering generic praise. Talk about how the defendant handled a difficult situation, supported someone in need, or contributed to their community. If you know about rehabilitation efforts or the support system waiting for them, include that too.

Acknowledge the seriousness of the situation. The judge knows the defendant pleaded guilty or was convicted. A letter that ignores this reality loses credibility immediately.

What to Avoid

Character letters go wrong in predictable ways. The biggest mistakes:

Asserting innocence when the defendant has pleaded guilty or been convicted. It contradicts the record and alienates the judge.
Attacking victims or law enforcement. Never criticize the people involved in the prosecution.⁷
Telling the judge what sentence to impose, unless the defense attorney has specifically asked you to request a particular outcome.
Letting the defendant write the letter for you. Judges can tell when letters are ghostwritten.⁷
Discussing the facts of the offense in detail. The court already has the facts of the case.

One less obvious mistake: submitting too many letters that all say the same thing. A handful of thoughtful, specific letters will serve the defendant better than 40 generic ones that water each other down.

What Happens If You Contact a Judge Improperly

Sending a letter directly to a judge without going through proper channels is not just ineffective. It can backfire. Under federal regulations, anyone who makes a prohibited ex parte communication, or encourages someone else to make one, may face sanctions.⁸ An attorney who does this can be excluded from the proceedings entirely.

For non-lawyers, consequences vary but can include having the letter struck from the record, being admonished by the court, or in some cases having sanctions imposed that affect your position in the case. Judges who receive improper contact are required to disclose it and may take whatever action they consider appropriate.⁹ File everything through the clerk’s office and serve copies on every other party, so there is no question about whether your communication was proper.
