Interlocutory Application (IA): Meaning, Explained Simply (2026)
An interlocutory application, usually written as IA, is an application made within a case that is already going on, asking the court to decide some issue or grant some relief before the final decision. It is a step inside a bigger case, not a case of its own. A party might file an IA for a stay, an interim injunction, to amend pleadings, to bring in a new party, or to condone a delay. This page explains what an IA means in plain words, when you file one, common types, a short Indian example, and the two things people confuse it with, the main petition and the interlocutory order. This is general information, last verified October 2026, and not legal advice.
- Meaning: an application filed inside a pending case for relief or a step before the final decision.
- Not a fresh case: it is numbered under the main suit or petition and rides on it.
- Common uses: stay, interim injunction, amending pleadings, adding a party, condoning delay.
- Usual support: an affidavit stating the facts.
- Answered by: an interlocutory (interim) order of the court.
01What an interlocutory application is
An interlocutory application, or IA, is an application filed inside a pending case asking the court for some relief or step before the case is finally decided. It is not a fresh case; it rides on the main case and is numbered under it.
The word "interlocutory" means something that happens in the middle, before the end. So an interlocutory application is a mid-case request. The main suit or petition decides the real dispute. An IA handles the smaller questions that come up while that main matter is still pending.
How it is numbered
An IA is tied to the main case. In most courts it carries its own IA number but is listed under the main suit or petition number, for example "IA No. 123 of 2026 in CS No. 45 of 2025". When the main case ends, the IAs in it usually come to an end too, unless the court has already disposed of them.
A main case asks the court to decide the dispute. An interlocutory application asks the court to do something while that dispute is still being decided.
02When you file an IA
You file an IA whenever you need the court to act on a point before the final hearing. Common reasons are:
- To protect the position: ask for a stay or an interim injunction so that things do not change while the case is pending.
- To fix the pleadings or parties: amend a plaint or written statement, or add or remove a party.
- To deal with time and procedure: condone a delay, seek more time, ask to lead additional evidence, or recall a witness.
- To seek urgent relief: ask for an early hearing or an urgent interim order.
An IA is usually supported by an affidavit stating the facts. For the basics of that supporting document, see our note on the meaning of an affidavit. For a step by step view of filing one, see how to file an interim application in India.
03Common types of interlocutory application
IAs are usually named after the rule or relief they seek. On the civil side, many are filed under specific orders of the Code of Civil Procedure, 1908.
| Purpose of the IA | Common basis |
|---|---|
| Temporary injunction / stay | Order XXXIX of the CPC |
| Add or strike out a party | Order I Rule 10 of the CPC |
| Amend pleadings | Order VI Rule 17 of the CPC |
| Condone delay | Section 5 of the Limitation Act, 1963 |
On the criminal side, applications within a pending matter (for example for bail, for exemption from appearance, or for release of property) are filed under the Bharatiya Nagarik Suraksha Sanhita, 2023, which replaced the Code of Criminal Procedure from 1 July 2024. The section numbering in the new code is new, so confirm the exact provision against the bare Act.

04A simple Indian example
Suppose a person files a civil suit to stop a neighbour from building on a shared wall. The main suit will take time to decide. Meanwhile the building work is going on fast.
The plaintiff files an interlocutory application asking for a temporary injunction to stop the construction until the suit is decided. The court hears this IA quickly and may pass an interim order either way. The main suit continues separately and decides the real question of rights over the wall. The IA only dealt with the urgent, in-between issue.
05IA vs main petition vs interlocutory order
These three are closely linked, which is why they get confused.
| Term | What it is |
|---|---|
| Main petition / suit | The case itself, which asks the court to finally decide the dispute |
| Interlocutory application (IA) | A request filed inside that case asking the court to act on a point before final decision |
| Interlocutory order | The order the court passes while deciding an IA or any mid-case issue |
So the IA is the request, and the interlocutory order is the court's answer to it. Both sit inside the main case. One more confusion is "interim" versus "interlocutory". In everyday court use the words are used loosely and often mean the same thing, an order that holds the position until the final decision.

08Frequently asked questions
What is an interlocutory application?
An interlocutory application, or IA, is an application filed inside a pending case asking the court for some relief or step before the case is finally decided. It is not a fresh case; it rides on the main case and is numbered under it.
What does IA stand for in court?
In court records, IA stands for interlocutory application. It is usually listed under the main case number, for example "IA No. 123 of 2026 in CS No. 45 of 2025".
What is the difference between an IA and the main case?
The main case asks the court to finally decide the dispute. An IA is a request made inside that case for the court to act on a smaller point before the final decision, such as a stay or an amendment.
What are common examples of interlocutory applications?
Common IAs ask for a temporary injunction or stay, to amend pleadings, to add or remove a party, to condone a delay, to lead additional evidence, or for an early or urgent hearing.
Is an IA the same as an interlocutory order?
No. An IA is the application, the request made to the court. An interlocutory order is the order the court passes while deciding that application. The IA is the question and the order is the answer.
Does an IA need an affidavit?
Usually yes. An interlocutory application is normally supported by an affidavit stating the facts that justify the relief asked for, though the exact requirement depends on the court and the type of application.
