A brief is a written argument you send to the Appeals Council explaining why you believe the judge's decision was wrong

When you disagree with a judge's decision on your SSDI claim, you can ask the Appeals Council to review the case. A brief is a document you write (or have someone write for you) that lays out your argument. It is not a summary of what happened—it is a persuasive document that tells the Appeals Council specifically what the judge got wrong and why the law supports your position instead.

The brief is optional. You can appeal without one. But if you send a brief, it becomes part of the official record the Appeals Council reads before making a decision. A well-written brief can be the difference between the Appeals Council agreeing with the judge and sending your case back for a new hearing.

You have 30 days from the date the judge's decision arrives to send your brief to the Appeals Council. If you miss that important date, you can still appeal, but you cannot submit a brief after the 30 days have passed.

Key Takeaways

  • A brief is a written argument explaining why the judge's decision was wrong, not a summary of your medical history or a retelling of the hearing.
  • You have 30 days from the date you receive the judge's decision to send your brief to the Appeals Council.
  • A brief should identify the specific legal or factual errors in the judge's decision and cite the evidence in the record that contradicts those findings.
  • You can write a brief yourself, have a representative write it, or ask a legal aid organization for help—you do not need a lawyer.
  • The Appeals Council will not consider new medical evidence or testimony in a brief; it only reviews what was already in the case file when the judge made the decision.

The three parts of a strong brief

A brief does not have to follow a rigid format, but the Appeals Council expects it to have a clear structure. The strongest briefs contain three main sections: an introduction that states what you are asking for, a body that explains the errors, and a conclusion that summarizes your argument.

Start by saying what you want the Appeals Council to do. For example: "I am asking the Appeals Council to reverse the Administrative Law Judge's decision dated [date] and remand my case for a new hearing" or "I am asking the Appeals Council to reverse the decision and award me benefits." This takes one or two sentences and tells the Appeals Council when ready what you are requesting.

The body of the brief is where you explain the errors. This is the longest section. You identify what the judge said, explain why it was wrong, and point to the evidence in the record that proves it was wrong. Do not argue about facts the judge found that you agree with—focus only on the findings you dispute.

End with a brief conclusion that restates your main argument in one or two sentences. The Appeals Council has read your entire brief; the conclusion straightforward reminds them of the core reason they should reverse the decision.

How to identify and explain errors in the judge's decision

The judge's written decision is the document you are responding to. Read it carefully and mark every statement you disagree with. There are two types of errors you can argue: factual errors and legal errors.

A factual error is when the judge found something to be true that the evidence does not support. For example, if the judge wrote "the claimant reported no pain during the hearing" but your medical records show you told the doctor about severe pain, that is a factual error. To argue a factual error, cite the specific page and line number of the evidence that contradicts what the judge said. If your doctor's note is on page 47 of the record, write: "The Administrative Law Judge found that the claimant reported no pain. However, the medical record dated [date] at page 47 documents the claimant's report of severe pain in the lower back."

A legal error is when the judge applied the wrong rule of law or did not follow the correct procedure. For example, if the judge ignored a medical opinion without explaining why, or if the judge did not consider all of your impairments together, those are legal errors. Legal errors are harder to argue without knowledge of Social Security law, but you can still point them out. Write what the judge did, what the law requires, and why the judge's action violated that requirement.

Do not argue about things you agree with. If the judge found that you have diabetes and you do have diabetes, do not spend space in your brief defending that finding. Use your space to address the findings you believe are wrong.

What evidence to cite and how to cite it

Every statement you make in your brief should be backed up by something in the case record. The case record includes your medical records, your work history, statements from doctors or other providers, your testimony at the hearing, and any other documents the judge reviewed.

When you cite evidence, be specific. Do not write "my medical records show I cannot work." Instead, write "the medical record dated March 15, 2023, from Dr. Sarah Chen, at page 52 of the record, documents that the claimant cannot lift more than 10 pounds due to back pain." The Appeals Council can then find that exact document and verify what it says.

If you have a representative, they may have a copy of the entire case record. If you do not, you can request it from the Appeals Council. Write to the address listed on the judge's decision and ask for a copy of the case record. There is no charge for this.

Do not submit new medical evidence in your brief. The Appeals Council will not consider it. If you have new medical evidence, you must request that the Appeals Council remand (send back) your case so that a new judge can review the new evidence. You can mention in your brief that new evidence exists and ask for a remand, but the new evidence itself cannot be part of the brief.

Common mistakes to avoid in your brief

Many people who write their own briefs make the same mistakes. The most common is writing a narrative—telling the story of your illness or injury from the beginning. The Appeals Council does not need this. They have already read your testimony and your medical records. Your brief should focus only on what the judge got wrong.

Another mistake is arguing about the judge's credibility findings. The judge decides whether to believe you and whether to believe the medical experts. The Appeals Council gives the judge's credibility findings a lot of weight and will not overturn them unless you can show the judge ignored clear evidence or made a logical error. Do not spend your brief arguing "the judge should have believed me." Instead, point to specific evidence that contradicts what the judge found.

A third mistake is making legal arguments without citing the law. If you argue that the judge applied the wrong legal standard, cite the regulation or the court decision that supports your position. You can find Social Security regulations at 20 CFR Part 404 (for Social Security Disability Insurance). If you do not know the specific regulation, describe the error clearly and let the Appeals Council's lawyers find the law.

Finally, do not assume the Appeals Council remembers your case. Even though they have your file, write your brief as if they are reading about your situation for the first time. Be clear, be specific, and do not skip steps in your reasoning.

How long your brief should be and how to format it

There is no official page limit for a brief to the Appeals Council, but shorter is usually better. Most effective briefs are 5 to 15 pages. If your brief is longer than 20 pages, you are probably repeating yourself or including information that is not necessary.

Format your brief so it is straightforward to read. Use a standard font like Times New Roman or Arial in 12-point size. Number your pages. Leave margins of at least one inch on all sides. If you are citing the case record, use a format like this: "Record at page 47" or "Exhibit 3, page 12."

At the top of the first page, write your name, your Social Security number, and the date. Include the date of the judge's decision you are appealing. If you have a representative, include their name and contact information.

You do not need fancy formatting or a cover page. The Appeals Council cares about what you say, not how it looks. A typed brief is better than a handwritten one because it is easier to read, but handwritten is acceptable if that is your only option.

Where to send your brief and what happens next

The judge's decision letter will tell you where to send your brief. Usually, you send it to the Appeals Council at the address listed on that letter. Make sure you send it within 30 days of receiving the decision.

Send your brief by mail or by the method the Appeals Council specifies. Keep a copy for your records. If you are mailing it, consider sending it by certified mail so you have proof of when it arrived.

After you send your brief, the Appeals Council will review your case. They will read the judge's decision, your brief, and the entire case record. They may decide to reverse the judge's decision, remand the case for a new hearing, or uphold the judge's decision. This process usually takes several months.

You will receive a written decision from the Appeals Council. If you disagree with that decision, you can file a lawsuit in federal court, but you must do so within 60 days of receiving the Appeals Council's decision.

When to get help writing your brief

If you have a representative—a lawyer, a non-lawyer representative, or an advocate—they can write your brief for you or help you write it. Many representatives have experience with Appeals Council briefs and know what arguments work best.

If you do not have a representative and cannot afford one, contact your local legal aid office. Many legal aid organizations will review your case and help you write a brief at no cost. You can find legal aid in your area by visiting the Legal Services Corporation website or calling 211.

If you decide to write your brief yourself, take your time. Read the judge's decision multiple times. Make a list of every finding you disagree with. For each one, find the evidence that contradicts it. Then write your brief section by section. Ask someone you trust to read it and tell you if it makes sense.

Frequently Asked Questions

Do I have to send a brief to appeal to the Appeals Council?

No. You can appeal without a brief. But a brief gives you a chance to explain your side in writing, and the Appeals Council will consider it. If you do not send a brief, the Appeals Council will review the judge's decision and the case record, but they will not hear your explanation of why the judge was wrong.

Can I send new medical evidence in my brief?

No. The Appeals Council will not consider new medical evidence submitted in a brief. If you have new medical evidence, ask the Appeals Council to remand your case so a new judge can review it. You can mention in your brief that new evidence exists and request a remand.

What if I miss the 30-day important date to send my brief?

You can still appeal, but you cannot submit a brief after the important date. If you have a good reason for missing the important date (like a serious illness or a mistake by your representative), you can ask the Appeals Council for an extension, but this is not may provide.

Can I call the Appeals Council to discuss my case instead of sending a brief?

No. The Appeals Council reviews cases based on the written record. They do not hold hearings or take phone calls about individual cases. Your brief is your opportunity to present your argument in writing.

What if the judge's decision has a typo or obvious mistake?

Point it out in your brief. If the judge wrote a date wrong or made a clear error that does not affect the outcome, mention it. But focus most of your brief on the errors that actually matter to your case—the findings about your medical condition and your ability to work.
