Writing a character reference for court for a family member comes down to a short, specific, honest letter addressed to the judge, routed through the defendant’s defense attorney, and delivered before the sentencing deadline. One page is the right length. Concrete stories about who your relative is outside the courtroom carry far more weight than adjectives, and federal law expressly allows the judge to consider that kind of personal background when deciding a sentence.1Office of the Law Revision Counsel. 18 US Code 3661 – Use of Information for Sentencing
Get the Case Details From the Attorney First
Before you draft anything, contact your family member’s defense lawyer. The attorney is the person who will submit your letter to the court as part of a sentencing memorandum,2State Appellate Defender Office and Criminal Defense Resource Center. Winning Your Case with Effective Character Letters and they can give you the specifics you’ll need:
- The defendant’s full legal name as it appears in court records, plus the case name and docket number (for example, United States v. Jane Doe, Case No. 1:25-cr-00123).
- The judge’s full name and title, used in the salutation as “The Honorable [Full Name].”
- The court’s full name and mailing address.
- The submission deadline, which is usually tied to the sentencing date.
- The attorney’s preferred format: PDF by email, a signed hard copy by mail, or both.
These details are not decorative. A missing docket number or a misspelled name can get a letter misfiled or left out of the sentencing packet entirely.
Format and Tone
Type the letter in standard business format. Use a readable 12-point font such as Times New Roman or Arial, one-inch margins, single-spaced text with a blank line between paragraphs. Put the date, the judge’s name and title, the court name, and the court’s address at the top left.
Open the salutation with “Dear Judge Smith” or “Your Honor.” Be respectful, but don’t confuse stiffness with respect. Write the way you would speak to someone you take seriously.
Keep it to one page. Judges read a stack of these for a single case, and brevity shows you’ve thought about what matters most. Two pages is the ceiling, and only if you genuinely cannot cut further. Anything longer tends to get skimmed.
What to Put in the Letter
Who You Are
Start with your full name, your relationship to the defendant, and how long you’ve known them. The judge needs this immediately to gauge the weight of your perspective. A sibling of 35 years reads differently from a cousin who reconnected last year. Then state plainly that you’re writing to provide a character reference in your family member’s pending case, and include the case name or docket number.
Specific Stories, Not Adjectives
The body of the letter is where it either works or doesn’t. The goal is to show, through examples, that the person you know is more than the worst thing they’ve done.2State Appellate Defender Office and Criminal Defense Resource Center. Winning Your Case with Effective Character Letters Phrases like “she’s a good person” or “he has a heart of gold” tell the judge nothing. Concrete stories tell the judge everything.
Think about moments that revealed character under pressure. Maybe your brother spent every weekend for a year driving your mother to chemotherapy when no one else stepped up. Maybe your sister tutored neighborhood kids for free while working two jobs. The strongest anecdotes are the ones only you could tell, because you were there. Two or three well-chosen examples beat a long list of qualities.
If your family member has shown genuine remorse, say so, and describe what you’ve personally seen rather than what you hope they feel. The same goes for changes since the incident. Enrollment in a treatment program, regular counseling, steady work, concrete steps to make amends: those facts deserve prominent placement. Judges look for evidence that someone is already doing the hard work, not just promising to start.
How to Close
Briefly reinforce the qualities you’ve described. You can respectfully ask for leniency, but ground the request in the character evidence you’ve just given, not in emotion. Sign off with “Respectfully” or “Sincerely,” sign in ink above your typed full name, and include your phone number and mailing address. Contact information tells the judge you stand behind what you’ve written.
What to Leave Out
The quickest way to undermine your letter is to minimize the offense or make excuses. Judges notice when a writer treats a serious charge as a misunderstanding. Your role is to speak to character, not to argue the case. Downplaying what happened makes the judge question everything else you’ve written.
Don’t blame the victim, criticize the prosecution, or second-guess the jury’s verdict. Comments about law enforcement being unfair or the system being broken will backfire. The judge is part of that system, and even a passing remark pulls attention away from your family member and toward your grievances.
Avoid legal opinions and speculation about facts you don’t have firsthand knowledge of. You’re a character witness, not a legal analyst. If you weren’t there for an event, don’t narrate it. Stay with what you’ve personally observed about who your family member is.
Keep the focus on the defendant, not on yourself. A paragraph about your own hardships or how the case has affected you dilutes the letter. One sentence to establish your own credibility is fine; a full paragraph about your career or health is not.
Honesty Has Legal Weight
Accuracy is not just a matter of credibility. If the defense attorney asks you to sign the letter under penalty of perjury, your written statements carry the same force as sworn testimony,3Office of the Law Revision Counsel. 28 US Code 1746 – Unsworn Declarations Under Penalty of Perjury which means knowingly false claims could expose you to perjury charges.
Even without a sworn declaration, submitting a document with material falsehoods to a federal court can be a separate offense carrying up to five years in prison. The statute applies to people who knowingly make false statements in any matter before a federal court. The law carves out an exception for the defendant and their own attorney; third-party letter writers are not covered by that exception.4Office of the Law Revision Counsel. 18 US Code 1001 – Statements or Entries Generally
Prosecution of a letter writer is rare in practice. The more immediate risk is simpler. If the judge catches an exaggeration or an inconsistency, the letter loses credibility and can hurt the defendant. Write what you know to be true and this problem disappears.
How to Submit It
Send the finished letter to the defense attorney, not to the judge or the court clerk. The attorney gathers all reference letters and files them together with the sentencing memorandum. Routing it through the lawyer is what gets it in front of the judge at the right moment.
Print the letter, sign it in ink above your typed name, and date it. If the attorney wants a digital copy, scan the signed version as a PDF. Some lawyers accept only mailed originals; others prefer email. Ask, and follow their instructions exactly.
Most character letters do not need to be notarized. A signed letter with your contact information is enough for the large majority of sentencing submissions. If the attorney specifically asks for notarization or a sworn declaration, follow that instruction, but don’t assume it’s required.
If you are more comfortable writing in a language other than English, the letter will need an English translation before it can be submitted. Most federal courts require a certified translation with a signed statement from the translator confirming accuracy and competency. Ask the attorney how that should be handled, since specific requirements vary by court.
Respect the deadline. A letter that arrives after the sentencing memorandum has been filed may never reach the judge. Build in a few extra days for mailing or last-minute corrections, and confirm receipt with the attorney after you send it.
