2255 Motion to Challenge a Federal Conviction or Sentence



A 2255 motion can challenge a federal conviction or sentence when constitutional violations or other fundamental errors made the judgment unlawful.

Deadlines, prior appeals, and supporting records determine whether a claim may proceed.


1. When Can a 2255 Motion Challenge a Federal Conviction?


Under 28 U.S.C. § 2255, a person in federal custody may ask the sentencing court to vacate, set aside, or correct a sentence. Custody can include prison, probation, or supervised release. It differs from a direct federal appeal or a state-prisoner habeas corpus petition.


Ineffective Assistance of Counsel

Under Strickland v. Washington, a claimant generally must show deficient performance and a reasonable probability of a different outcome. Inadequate investigation or faulty plea advice may support such a claim. Massaro v. United States allows ineffective-assistance claims to be raised first under § 2255 even if omitted on direct appeal.

Constitutional Violations and Unlawful Sentences

Withheld material exculpatory evidence, fundamental due-process violations, a lack of jurisdiction, or a sentence exceeding statutory limits may support relief. Disagreement with a verdict or an ordinary error does not automatically qualify.


2. 2255 Motion Filing Deadlines and Procedural Restrictions


A § 2255 motion generally has a one-year filing limit, but it does not necessarily run from sentencing. Plea waivers, omitted appellate claims, and previous motions also affect eligibility.


The One-Year Filing Deadline and Exceptions

Section 2255(f) uses the latest date applicable to the claim: (1) final judgment; (2) removal of an unlawful government impediment that prevented filing; (3) the Supreme Court's initial recognition of a new right made retroactive on collateral review; or (4) when supporting facts could have been discovered through due diligence. After direct appeal, the certiorari filing period may affect finality. Equitable tolling requires both diligence and extraordinary circumstances.

Appeal Waivers and Second or Successive Motions

A plea agreement may waive some collateral challenges. Claims omitted on direct appeal may be defaulted absent cause and actual prejudice or a showing of factual innocence. Ineffective-assistance claims receive different treatment under Massaro.

A second or successive motion generally needs court-of-appeals authorization under § 2255(h), based on qualifying new evidence of innocence or a new constitutional rule made retroactive by the Supreme Court. In Bowe v. United States (2026), the Supreme Court ruled that § 2244(b)(1)'s repeated-claim bar does not apply, but § 2255(h)'s requirements remain.


3. Preparing Evidence for a Federal 2255 Motion


Rule 2 requires all available grounds, supporting facts, and requested relief. Federal courts provide Form AO 243, subject to applicable local filing rules. Later motions face strict limits.


Trial Transcripts, Plea Agreements, and Sentencing Records

Judgments, plea transcripts, sentencing records, and appeal dockets establish the case history and deadlines. These records help identify grounds for post-conviction relief.

Affidavits and Evidence Outside the Trial Record

Attorney correspondence, witness declarations, and previously unavailable documents may establish facts missing from the trial record. Discovery is not automatic: Rule 6 permits specific requests on a showing of good cause. Evidence must support a recognized legal claim.


4. How Long Does a 2255 Motion Take after Filing?


There is no uniform federal decision deadline. Hearings, disputed facts, and appeals may extend proceedings beyond a year.


Initial Review, Government Response, and Hearings

Under Rule 4, the court screens the motion and may dismiss it if the records clearly defeat relief. Otherwise it orders a government response. Section 2255(b) calls for a hearing unless the motion and case records conclusively show that relief is unavailable.

Possible Outcomes and Appeals after Denial

The court may vacate the judgment, order resentencing or a new trial, or correct the sentence. An appeal generally requires a certificate of appealability (COA) based on a substantial showing of the denial of a constitutional right. The notice of appeal is ordinarily due within 60 days after the final order, even if a certificate issues. If denied, a COA may be sought from the appeals court.

Other post-conviction remedies have separate limits. In Fernandez v. United States (2026), the Supreme Court ruled that a challenge to a conviction's validity cannot bypass § 2255 through compassionate release.


5. Frequently Asked Questions about 2255 Motions


Q: Can I file a 2255 motion after pleading guilty?

A: Potentially. The plea's voluntariness, any enforceable collateral-attack waiver, and the supporting evidence determine which claims remain available.

Q: Will the court appoint a lawyer for my 2255 motion?

A: Not automatically. Under Rule 8(c), counsel must be appointed if an evidentiary hearing is warranted and the applicant qualifies under 18 U.S.C. § 3006A.
