An indictment ( // in-DYT-mənt) is a criminal accusation that a person has committed a crime. In jurisdictions that use the concept of felonies, the most serious criminal offence is a felony; jurisdictions that do not use the concept of felonies often use that of an indictable offence—an offence that requires an indictment.
The criminal law in India  is derived from the colonial-era British system, does not use a jury system and is codified in the Criminal Procedure Code (CrPC). Criminal offenses are divided into two broad categories: cognisable offenses and non-cognisable offenses. The police are empowered to start investigating a cognisable offense. The complaint is considered merely an accusation. However, in both cognisable and non-cognisable offenses, the trial starts only with the "Framing of Charges" similar to the concept of indictment. The trial court does not proceed with the trial if the evidence is insufficient to make out a charge.
In England and Wales (except in private prosecutions by individuals) an indictment is issued by the public prosecutor (in most cases this will be the Crown Prosecution Service) on behalf of the Crown, which is the nominal plaintiff in all public prosecutions under English law. This is why a public prosecution of a person whose surname is Smith would be referred to in writing as "R v Smith" (or alternatively as "Regina v Smith" or "Rex v Smith" depending on the gender of the Sovereign, Regina and Rex being Latin for "Queen" and "King" and in either case may informally be pronounced as such) and when cited orally in court would be pronounced "the Crown against Smith". 
All proceedings on indictment must be brought before the Crown Court.  By virtue of practice directions issued under section 75(1) of the Senior Courts Act 1981, an indictment must be tried by a High Court judge, a circuit judge or a recorder (which of these it is depends on the offence).
The Indictment Rules 1971 were revoked by the Criminal Procedure (Amendment) Rules 2007  (on the whole) incorporated into the Criminal Procedure Rules 2010.  The form and content and the service of an indictment are governed by Rule 14 of the CPR 2012.  Additional guidance is contained in the Consolidated Criminal Practice Direction Part IV.34. 
As to the preferring of a bill of indictment and the signing of an indictment, see section 2 of the Administration of Justice (Miscellaneous Provisions) Act 1933 and the Indictments (Procedure) Rules 1971 (S.I. 1971/2084) made thereunder, as amended and modified by the Indictments (Procedure) (Amendment) Rules 1983 (S.I. 1983/284), the Indictments (Procedure) (Amendment) Rules 1988 (S.I. 1988/1783), the Indictments (Procedure) (Amendment) Rules 1992 (S.I. 1992/284), the Indictments (Procedure) (Amendment) Rules 1997 (S.I. 1997/711), the Indictments (Procedure) (Modification) Rules 1998 (S.I. 1998/3045) and the Indictments (Procedure) (Amendment) Rules 2000 (S.I. 2000/3360).

In Scotland, all of these cases brought in the High Court of Justiciary are brought in the name of the Lord Advocate and will be tried on indictment. In a sheriff court where trials proceed using the solemn proceedings they will also be tried on indictment and are brought in the name of a procurator fiscal.
The Fifth Amendment to the Constitution of the United States states in part: "No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia when in actual service in time of War or public danger". The requirement of an indictment has not been incorporated against the states; therefore, although the federal government uses grand juries and indictments, not all U.S. states do. 
In many, but not all, United States jurisdictions that use grand juries, prosecutors often have a choice between seeking an indictment from a grand jury and filing a charging document directly with the court. Such a document is usually called an information, accusation, or complaint, to distinguish it from a grand-jury indictment. To protect the suspect's due-process rights in felony cases (where the suspect's interest in liberty is at stake), there is usually a preliminary hearing, at which a judge determines whether there was probable cause to arrest the suspect who is in custody. If the judge finds such probable cause, he or she binds, or holds over, the suspect for trial.
The substance of an indictment or other charging instrument is usually the same, regardless of the jurisdiction: it consists of a short and plain statement of where, when, and how the defendant allegedly committed the offense. Each offense usually is set out in a separate count. Indictments for complex crimes, particularly those involving conspiracy or numerous counts, may run to hundreds of pages. However, in other cases an indictment for a crime as serious as murder, may consist of a single sheet of paper.
Indictable offenses are normally tried by jury, unless the accused waives the right to a jury trial. Although the Sixth Amendment mandates the right to a jury trial in any criminal prosecution, the vast majority of criminal cases in the United States are resolved by the plea-bargaining process.
A direct indictment is one in which the case is sent directly to trial before a preliminary inquiry is completed or when the accused has been discharged by a preliminary inquiry.   It is meant to be an extraordinary, rarely used power to ensure that those who should be brought to trial are in a timely manner or where an error of judgment is seen to have been made in the preliminary inquiry. 
An indictment can be sealed so that it stays non-public until it is unsealed. This can be done for a number of reasons. It may be unsealed, for example, once the named person is arrested or has been notified by police. 
A superseding indictment takes the place of the previous indictment in use.
