IA stands for Interlocutory Application. It is a formal application filed before a court during the pendency of a main case — not to decide the final rights of parties, but to seek temporary or interim directions, reliefs, or orders that prevent injustice until the main case is decided.
Simply put, when a case is ongoing and a party needs the court to do something urgently — stop the other party from selling disputed property, grant temporary custody of a child, or stay the operation of a lower court order — they file an IA.
Interlocutory applications are the bridge between the start and the finish of litigation. They keep the wheels of justice turning even when the final verdict is years away.

Why Are IAs Filed?
Litigation in India can take years — sometimes decades. During this time, if nothing is done to protect the parties’ interests, the final judgment may become meaningless. An IA serves several crucial purposes:
Preventing irreparable harm — If a property is about to be sold before the court decides the ownership dispute, an IA for a temporary injunction stops the sale.
Preserving status quo — An IA maintains the existing state of affairs so that neither party gains an unfair advantage while the case is pending.
Procedural efficiency — IAs resolve interim disputes — like whether additional evidence can be submitted, or whether a witness can be recalled — without waiting for the final hearing.
Checks on abuse — Applications for stay, injunction, and receiver serve as deterrents against parties who might use litigation to harm opponents.
Common Types of Interlocutory Applications
Temporary Injunction (Order XXXIX CPC) — The most common IA in civil cases. Restrains a party from doing something — selling property, disclosing confidential information, or continuing an activity — until the main case is decided.
Stay of Execution — Stays the execution of a decree while an appeal is pending, preventing enforcement until the appellate court decides.
Amendment of Pleadings (Order VI, Rule 17 CPC) — Filed when a party wants to change or add to their plaint or written statement after filing.
Appointment of Receiver (Order XL CPC) — Court-appointed person to manage disputed property when there’s a risk of damage or mismanagement.
Bail Applications (CrPC/BNSS) — In criminal cases, bail applications (regular bail, anticipatory bail, interim bail) are technically interlocutory applications.
Application for Additional Evidence — Filed to bring additional documents or witnesses before the court that weren’t part of the original filing.
IA Procedure — How It Works
- Draft the IA clearly stating the nature of relief sought and reasons
- File the IA in the court where the main case is pending
- Serve notice to the opposing party
- Both parties argue the IA (usually on short cause)
- Court passes an interlocutory order — granting or rejecting the interim relief
- Interlocutory orders can be modified if circumstances change
Frequently Asked Questions (FAQs)
Q: What is the full form of IA in law? ]
A: IA stands for Interlocutory Application — a petition filed during a pending case before a court to seek temporary or interim relief or directions.
Q: What is the difference between an IA and a main petition?
A: The main petition decides the final rights of the parties. An IA only seeks temporary or interim directions during the pendency of the main case — it does not decide who ultimately wins.
Q: What is the most common type of IA in civil courts?
A: Application for temporary injunction under Order XXXIX of the CPC is the most commonly filed IA in civil courts — restraining parties from acting in a way that could harm the other party.
Q: Can IA orders be appealed?
A: Generally, interlocutory orders are not directly appealable. However, some may be challenged in revision or through the inherent powers of High Courts under Section 482 CrPC (now BNSS equivalent).
Q: Does an IA decide the final outcome of a case?
A: No. An IA order is interim in nature. It does not determine the final rights of the parties. Those are decided only when the main case reaches its final judgment.
Q: What is the legal basis for filing an IA in civil cases?
A: Section 141 of the CPC provides that the procedure for suits shall be followed in all civil proceedings. Orders XXXIX and XL specifically govern injunctions and receivers, which are common subjects of IAs.
Q: What happens if an IA is not decided quickly?
A: Courts have discretion on timing. However, delay in deciding IAs — especially for injunctions — can cause irreparable harm. Parties can press for early hearing. Higher courts can direct lower courts to decide IAs within a specified time.
Q: Can an IA be filed in criminal cases?
A: Yes. Bail applications, applications for discharge, stay of proceedings, and applications for recalling witnesses are all interlocutory applications in criminal proceedings.
