What the form asks for
The AO 242 form walks through the information a judge needs to decide whether custody is lawful:
- the petitioner’s name, identification number, and place of confinement;
- what the petitioner is challenging, such as immigration detention or how a sentence is being carried out;
- any earlier administrative steps, including bond requests and appeals to the Board of Immigration Appeals;
- each ground for relief, with the supporting facts stated briefly;
- the relief requested and a signed declaration under penalty of perjury.
Where the form falls short in immigration cases
The form leaves a few lines for each ground. Immigration detention cases usually turn on which detention statute applies, how long custody has lasted, what happened at any bond hearing, and whether removal is realistically going to occur. Those issues need legal argument and exhibits, not one-sentence answers. A lawyer-drafted petition typically pairs the form’s structure with a memorandum of law, a declaration from the detainee or family, and supporting records.
Naming the correct respondents matters as well. The form asks for the custodian, and in immigration cases that is usually the warden of the facility; practitioners commonly add the ICE Field Office Director. An incomplete caption can delay the case.
Filing the form
The petition is filed with the clerk of the federal district court for the district where the person is held. People without lawyers can usually file on paper or by mail; attorneys file electronically. Along with the petition, the filer pays the $5 fee or submits an application to proceed in forma pauperis. A family member may sign as “next friend” when the detainee cannot do so personally, but must explain why.
Frequently asked questions
What form is used for a § 2241 habeas petition?
The national federal form is AO 242, Petition for a Writ of Habeas Corpus Under 28 U.S.C. § 2241. Some district courts require a local version, so check the clerk’s office or court website for the district where the person is detained.
Can I file a habeas petition without a lawyer?
Yes. Federal courts accept petitions from people representing themselves. In immigration detention cases, however, outcomes often depend on statutory and constitutional arguments that the short form does not leave room for, so counsel can make a significant difference.
