Section 2255 Motions to Vacate a Federal Sentence

By Elizabeth Franklin-Best, Esq., and Christopher Zoukis, JD, MBA

For a person convicted in federal court, the motion under 28 U.S.C. § 2255 is the central tool of post-conviction relief. It is the primary way to ask a court to vacate, set aside, or correct a federal conviction or sentence after the direct appeal has run its course. It is also strictly limited — by a one-year deadline, by demanding procedural rules, and by a high bar to bringing more than one. Understanding the 2255 motion is essential to understanding what is still possible after an appeal.

Section 2255 litigation sits at the center of our post-conviction practice. Elizabeth Franklin-Best, our principal attorney, wrote Reversing Your Criminal Conviction — a book devoted to precisely this kind of challenge — holds a Best Lawyers in America 2026 “Best Lawyer” recognition in Appellate Practice, and earned the firm a Chambers USA 2026 ranking for Litigation: White-Collar Crime & Government Investigations. Admitted to the United States Supreme Court and every one of the twelve federal circuits, she maintains a nationwide collateral-review practice and has served as counsel of record in reported post-conviction decisions including Vandross v. Stirling, 986 F.3d 442 (4th Cir. 2021), and Bryant v. Stephan, 998 F.3d 128 (4th Cir. 2021). Together with Managing Director Christopher Zoukis, she brings that depth to every collateral attack the firm files. The 2255 motion is governed by 28 U.S.C. § 2255 and the Rules Governing Section 2255 Proceedings.

This guide explains the Section 2255 motion in depth — what it is, the grounds for relief, the strict one-year statute of limitations and its starting points, procedural default, the procedure from filing to ruling, the certificate of appealability, and the demanding rules on second or successive motions. If you are considering a 2255 motion, a 2255 motion lawyer should evaluate the case before the deadline runs.

Quick Answer

Question	Answer
What is a Section 2255 motion?	A motion by a federal prisoner to vacate, set aside, or correct a sentence — the primary tool for collaterally challenging a federal conviction or sentence.
Where is it filed?	In the district court that imposed the sentence, not in the court of appeals.
What is the deadline?	A strict one-year statute of limitations, running from the latest of four dates the statute defines — most often when the conviction became final.
What are the grounds?	A constitutional violation, lack of jurisdiction, a sentence exceeding the legal maximum, or that the sentence is otherwise subject to collateral attack.
Can I file more than one?	Generally no. A second or successive 2255 motion requires certification from the court of appeals under a very narrow standard.
How do we start?	With a paid, one-hour initial consultation: we compute the exact filing deadline and give a candid read on every available ground.

• The grounds are a constitutional violation, lack of jurisdiction, a sentence over the legal maximum, or other collateral attack.
• A strict one-year statute of limitations applies under § 2255(f), running from the latest of four defined trigger dates.
• Finality is measured under Clay v. United States — for most appealed cases, when the 90-day window to seek certiorari closes.
• Equitable tolling exists but is reserved for diligent movants blocked by truly extraordinary circumstances.
• Claims that could have been raised on direct appeal are generally procedurally defaulted — but ineffective-assistance claims are not.
• To appeal a denial, the movant must obtain a certificate of appealability.

• Because there is generally only one opportunity, the first 2255 motion must be complete and done right.

What Is a Section 2255 Motion?

A Section 2255 motion is a motion by a federal prisoner asking the court to vacate, set aside, or correct the sentence. It is filed under 28 U.S.C. § 2255, and it is the primary mechanism for collaterally attacking a federal conviction or sentence — that is, for challenging it outside the direct line of trial and appeal.

The 2255 motion is filed in the district court that imposed the sentence — not in the court of appeals. It is decided, in the first instance, by that district court, often by the same judge who presided over the case. In this respect it differs from a direct appeal, which goes to a higher court.

The 2255 motion exists because some serious problems with a conviction cannot be addressed on direct appeal. The direct appeal is confined to the trial record; many of the strongest collateral claims — above all, ineffective assistance of counsel — depend on facts outside that record. The 2255 motion is the vehicle built to hear those claims.

The Grounds for 2255 Relief

Section 2255 sets out four grounds on which a federal prisoner may seek relief. A 2255 motion must rest on one of them.

• Constitutional violation. That the sentence was imposed in violation of the Constitution or laws of the United States.
• Lack of jurisdiction. That the court was without jurisdiction to impose the sentence.
• Sentence in excess of the maximum. That the sentence was in excess of the maximum authorized by law.
• Otherwise subject to collateral attack. That the sentence is otherwise subject to collateral attack.

The first ground is the broadest and the most common. Within it, the single most frequent 2255 claim is ineffective assistance of counsel — a claim that the defendant’s lawyer performed below the constitutional standard and that the deficient performance caused prejudice. Other constitutional claims, such as certain Brady violations discovered after trial or claims based on a new retroactive rule of constitutional law, also proceed under this ground. The 2255 motion is not, however, a vehicle for ordinary trial error that should have been raised on direct appeal — a point addressed below.

The One-Year Deadline

The most unforgiving feature of the 2255 motion is its deadline. A 2255 motion is governed by a strict one-year statute of limitations. Miss it, and even a strong claim can be permanently barred.

Under § 2255(f), the one-year period runs from the latest of four statutory trigger dates:

1. Finality. The date on which the judgment of conviction became final — the trigger that controls the overwhelming majority of cases.
2. Government impediment removed. The date on which an unlawful, government-created impediment to filing was removed, for movants who were actually prevented from filing by government action.
3. New retroactive right. The date on which the Supreme Court initially recognized a new right, if that right has been made retroactively applicable to cases on collateral review.
4. New facts. The date on which the facts supporting the claim could first have been discovered through the exercise of due diligence.

The third and fourth triggers matter more than many people assume. A Supreme Court decision recognizing a new retroactive right, or evidence that no amount of diligence could have surfaced earlier, can restart the clock years after sentencing. The triggers are also measured claim by claim — different claims in the same motion can carry different deadlines, and we calculate each one separately.

For most movants, the operative trigger is the first — finality — and computing it precisely is the opening task of any 2255 representation. The next two sections explain how finality is measured and the rare circumstances in which courts will extend the deadline. The safe course is always to treat the one year as firm and to act well inside it.

Applied Insight: More strong 2255 claims are lost to the one-year deadline than to any weakness on the merits. The clock often starts while a person is still adjusting to incarceration, and a year passes quickly. Anyone who believes they may have a 2255 claim should have counsel calculate the exact deadline immediately — and should not assume there is more time than there is.

When a Federal Conviction Becomes Final

The Supreme Court settled the most common finality question in Clay v. United States, 537 U.S. 522 (2003). For a defendant who pursues a direct appeal but does not petition the Supreme Court, the judgment becomes final when the time for seeking certiorari expires — 90 days after the court of appeals enters judgment or denies rehearing — not when the appellate mandate issues. If the defendant does seek certiorari, finality waits until the Supreme Court denies the petition or decides the case.

For a defendant who never appeals, the conviction generally becomes final when the short window for filing a notice of appeal closes — ordinarily 14 days after entry of judgment. These distinctions matter enormously in practice: two people sentenced the same week can face 2255 deadlines months apart depending on how their appeals concluded. We compute the date to the day, in writing, at the outset of every representation, and we build the work schedule backward from it.

Equitable Tolling of the 2255 Deadline

In rare cases, a court may equitably toll the one-year period. The governing standard comes from Holland v. Florida, 560 U.S. 631 (2010), where the Supreme Court held that AEDPA’s one-year limitations period is subject to equitable tolling when the petitioner shows that he pursued his rights diligently and that some extraordinary circumstance stood in his way. Holland itself involved a state prisoner’s petition under § 2254, but the federal courts of appeals apply the same two-part standard to motions under § 2255.

Both parts are demanding. A lawyer’s miscalculation of the deadline, garden-variety neglect, and limited law-library access are routinely held not to be extraordinary; serious attorney misconduct, incapacitating illness, or active deception have sometimes qualified — but only for movants who can document their own diligence throughout. Equitable tolling is a safety net with very wide holes. No filing strategy should ever depend on it.

Procedural Default

Beyond the deadline, the 2255 motion is shaped by the doctrine of procedural default. The general rule is that a claim that could have been raised on direct appeal, but was not, is procedurally defaulted and cannot be raised for the first time in a 2255 motion.

There are two recognized paths around a default, and the Supreme Court mapped both in Bousley v. United States, 523 U.S. 614 (1998). A defaulted claim may still be heard if the movant demonstrates cause for the failure to raise it earlier and actual prejudice from the error, or if the movant establishes actual innocence — meaning factual innocence, shown so persuasively that it is more likely than not no reasonable juror would have convicted. Bousley also illustrates how narrow the gateways are: the perceived futility of raising a claim does not count as cause, and where the government gave up more serious charges in plea bargaining, the innocence showing must extend to those forgone charges too. The exceptions are real, but no strategy should be built on them.

Importantly, the procedural-default rule does not bar the most common 2255 claim. In Massaro v. United States, 538 U.S. 500 (2003), the Supreme Court held that an ineffective-assistance-of-counsel claim may be brought under § 2255 whether or not the movant could have raised it on direct appeal. The reasoning is practical: these claims usually turn on evidence outside the trial record — what counsel investigated, what advice was given, why choices were made — and the district court on collateral review is the forum equipped to develop those facts. Massaro is a large part of why ineffective assistance sits at the heart of 2255 litigation.

The 2255 Process

The 2255 motion follows a defined process in the district court.

The motion is filed in the sentencing court, setting out each claim and the supporting facts. The court conducts an initial review and may dismiss claims that are plainly without merit. If the motion is not summarily dismissed, the government is ordered to respond, and the movant may reply. The statute provides that the court must grant a hearing on the motion unless the motion and the files and records of the case conclusively show that the prisoner is entitled to no relief — so where a claim turns on disputed facts outside the record, an evidentiary hearing may be required. After considering the motion, the response, the record, and any hearing, the court rules.

If the court grants relief, the remedy depends on the claim — it can include vacating the conviction, vacating the sentence and resentencing, or other corrective action. If the court denies the motion, the movant’s path forward runs through the certificate of appealability.

When the Court Must Hold an Evidentiary Hearing

Section 2255(b) sets the hearing standard: the court must grant a prompt hearing unless the motion and the files and records of the case “conclusively show that the prisoner is entitled to no relief.” The word conclusively does real work. Where the movant alleges specific facts that, if true, would entitle him to relief — and the existing record does not flatly refute them — the court ordinarily cannot resolve the factual dispute on the papers alone.

In practice, the difference between earning a hearing and being dismissed on the pleadings usually traces back to how the motion was built. Vague or conclusory allegations are denied without hearings every day. Sworn declarations — from the movant, from witnesses trial counsel never contacted, from the trial lawyer where cooperation is possible — and documentary exhibits force the court to confront a genuine dispute that only live testimony can resolve. We draft every motion on the assumption that the hearing decision will be made on the paperwork, because it almost always is.

The Certificate of Appealability

A defendant whose 2255 motion is denied cannot simply appeal as of right. To appeal the denial, the movant must obtain a certificate of appealability.

A certificate of appealability may be issued only if the movant makes a substantial showing of the denial of a constitutional right. In practice, this means showing that reasonable jurists could debate whether the motion should have been resolved differently, or that the issues deserve further proceedings. The certificate can be sought first from the district court and, if denied there, from the court of appeals.

The certificate of appealability is a real gate. Without one, the denial of the 2255 motion stands, and the appellate court will not reach the merits. Framing the issues so that they meet the certificate standard is part of litigating a 2255 motion well — the motion should be built, from the start, with the possibility of appeal in mind.

Second or Successive Motions

One of the most consequential features of 2255 law is the strict limit on filing more than one motion. A defendant generally gets one 2255 motion — and the rules on a “second or successive” motion are severe.

Before a second or successive 2255 motion can be filed in the district court, the movant must obtain certification from the appropriate court of appeals under § 2255(h). The court of appeals may certify the motion only if it contains either newly discovered evidence that, viewed in light of the evidence as a whole, would be sufficient to establish by clear and convincing evidence that no reasonable factfinder would have found the movant guilty, or a new rule of constitutional law made retroactive to cases on collateral review by the Supreme Court and previously unavailable.

The Supreme Court closed a long-debated workaround in Jones v. Hendrix, 599 U.S. 465 (2023). For years, several circuits had allowed prisoners barred from a second 2255 motion to bring statutory-interpretation claims through a traditional habeas corpus petition under § 2241, relying on the saving clause in § 2255(e). Jones held that § 2255(h)’s two gates are exclusive — a movant’s inability to satisfy them does not render the 2255 remedy “inadequate or ineffective,” and it does not open the § 2241 door. After Jones, a claim that the sentencing court misread the statute of conviction generally must fit through § 2255(h) or it cannot be brought at all.

The Supreme Court returned to these gates in Bowe v. United States, 607 U.S. 13 (2026). The decision clarified two points in the federal prisoner’s favor. First, the “old-claim” bar in § 2244(b)(1) — which requires dismissal of a claim already presented in a prior petition — applies by its terms only to state prisoners proceeding under § 2254, not to federal prisoners moving under § 2255; a court of appeals therefore cannot refuse to certify a successive 2255 motion simply because the claim was raised before. Second, the Court held that § 2244(b)(3)(E)’s bar on certiorari does not reach federal prisoners, so the Supreme Court can review a court of appeals’ refusal to authorize a successive motion. Even so, Bowe reaffirmed that § 2255(h) supplies the “two — and only two — conditions” in which a second motion may proceed, and that a movant who clears them still faces the § 2255(f) deadline. The narrow gates remain; Bowe simply confirms which ones actually apply.

Those are narrow gates. The practical consequence is enormous: because a defendant ordinarily has only one full opportunity, the first 2255 motion must be done right. Every viable claim should be identified and included; a strong claim omitted from the first motion may be very difficult, or impossible, to raise later. This is the single strongest reason to have experienced counsel prepare a 2255 motion rather than treating it as a routine filing.

Applied Insight: The “one bite at the apple” reality of 2255 practice cannot be overstated. A first 2255 motion that misses a meritorious claim does not just lose that claim now — it may lose it forever, because the door to a second motion is barely open. A thorough, careful, complete first motion is not a luxury; it is the entire strategy.
