What Is a 5K1.1 Motion—and What If You Have No Cooperation Agreement?
Cooperation is one sentencing subject. Your personal record, accountability and preparation deserve attention whether or not it is part of your case.

Searches for “5K1,” “5K one” or “5K1.1 motion” generally refer to U.S.S.G. § 5K1.1. It addresses a sentence below the applicable guideline range on a government motion based on substantial assistance in investigating or prosecuting another person.
There is no fixed discount. The assessment includes the assistance’s significance, reliability, extent, timeliness and any resulting risk. A cooperation agreement, the government’s motion and the court’s decision are distinct steps.
A § 5K1.1 motion does not by itself supply authority to go below a statutory mandatory minimum. Counsel must examine the separate authority under 18 U.S.C. § 3553(e), where applicable.
5K1.1 and Rule 35(b): understand the timing.
| Topic | Where it fits | What to clarify with counsel |
|---|---|---|
| § 5K1.1 | Substantial assistance considered at sentencing. | Government motion, agreement terms and requested treatment of the guideline range. |
| Rule 35(b) | A government motion for a reduction after sentencing based on substantial assistance. | Timing requirements, any applicable exception and the assistance involved. |
| Personal mitigation | The individual record relevant to sentencing. | What facts and completed actions support counsel’s sentencing request. |
These are not interchangeable routes. SAG does not negotiate cooperation, arrange proffers or promise government motions. Discuss disclosures and the consequences of cooperation with your defense attorney before acting.
The experience behind the preparation
A substantial reduction. No cooperation agreement.
Joseph De Gregorio faced a federal guideline range of 41–51 months. He received 12 months and one day without a cooperation agreement. He spent 124 days in a federal prison facility before moving to home confinement.
Those are two different outcomes: the sentence imposed and the time spent inside a prison facility. Home confinement remained part of serving the sentence. His experience informs SAG’s focus on preparation before sentencing and disciplined planning afterward.
The approximately 75% comparison uses the upper end of the 41–51-month range; the comparison with the lower end is approximately 71%. It is not a reduction from an already-imposed 51-month sentence. These are individual results, not a typical outcome or promise. Read Joseph’s full background and published case discussion →
No cooperation agreement does not mean no preparation.
Joseph’s experience gives this question particular relevance to SAG. He received 12 months and one day against a 41–51-month guideline range without a cooperation agreement. The practical lesson is to take the individual sentencing record seriously. It is not a recommendation to accept or reject cooperation.
Your lawyer evaluates the legal strategy. Your preparation can focus on the work within your control: a complete personal history, accurate records, responsibility expressed honestly and concrete evidence of change. SAG helps organize that work with the defense team.
Build evidence beyond a character description.
“I am a different person” is a conclusion. Relevant records can show what changed, when it changed, how long it has been sustained and who can verify it. Treatment participation, financial controls, education, employment, restitution efforts and service should be described accurately and supported where possible.
Prepare for the PSR and personal statement.
Work through chronology, dates and missing documents before the interview. Discuss offense-related questions with counsel. A personal statement should remain in the defendant’s voice; memorizing a polished speech is not the objective.
Questions people ask about a 5K1.1 motion.
Does cooperating guarantee a lower sentence?
No particular result can be promised. Agreement terms, government action and the court’s decision matter. Your attorney should explain both obligations and uncertainty before you make decisions.
Is acceptance of responsibility the same as cooperation?
No. Taking responsibility for your own conduct and assisting authorities concerning another person are different concepts. Counsel evaluates the provisions that apply to your case.
Can I prepare mitigation if a motion is expected?
Yes. An expected motion does not explain your entire history, the effects of the offense, your changes or your future plan. Discuss how personal preparation fits counsel’s overall presentation.
Can SAG get me a 5K1.1 motion?
No. SAG offers sentencing preparation and consulting, not government cooperation agreements or legal representation. Its role is to help develop an organized, truthful record for use with counsel.
