A writ is a formal, legal document that orders a person or entity to perform or to cease performing a specific action or deed. Writs are drafted by courts or other entities with jurisdictional or legal power.

A writ petition contains averments or statements sworn, in form of affidavit. The Supreme Court has the authority to issue a writ against the government or a person who is in the territory of India. A High Court can only issue a writ against the government or a person who lies in the jurisdiction of such a High Court.
