Requesting an Extension While the Period Runs
The same request made two days apart is judged by two entirely different standards. Before the deadline the question is good cause; after it, the question becomes excusable neglect, and the gap between those two tests is far wider than the two days suggests.

The rule in short
Where a period has not yet expired, an extension is generally available on a showing of good cause: an acceptable reason, a realistic proposed date and an absence of prejudice to the other side. Once the period has passed, the applicant must usually also explain the failure to act in time, which is a materially harder exercise. Asking early is therefore worth considerably more than asking well.
Extensions are granted routinely and refused predictably. The single variable that moves the outcome most is not the strength of the reason but whether the request arrived before the period ran out.
What the test usually is
Good cause. A reason the forum can accept, which is a considerably lower bar than the test applied after expiry.
A proposed date. The application should say how long is needed rather than asking for an unspecified extension.
Absence of prejudice. Whether the other side is harmed by the delay, and if so how.
Effect on the timetable. Whether the extension disturbs a hearing date or other fixed points.
Diligence so far. What has been done during the period is part of the picture.
Whether it was foreseeable. A difficulty that was obvious weeks ago is a weaker basis than one that arose yesterday.
Consent, if obtained. An unopposed request is usually granted with fairly minimal scrutiny.
Whether anything turns on the date. An extension that affects nothing beyond the applicant is easier to grant than one with consequences.
Proportionality. A short extension on an unremarkable step is treated quite differently from a long one on a critical deadline.
The stage of the case. Requests early in a matter are generally easier than those made close to a final hearing date.
What a good application contains
The deadline and its source. The rule or order that set it, and the date it expires, per reading a deadline out of the rule.
What has been done so far. A short account of the work completed, which establishes diligence without being asked.
Why more time is needed. Specific and factual rather than a general reference to pressure of work.
A precise proposed date. A date the applicant can actually meet, per how long to ask for.
The position of the other side. Whether they consent, oppose or have not responded, and when they were asked.
The effect on later dates. Whether the extension has consequences for the rest of the timetable.
Any prejudice addressed. Anticipating the objection is better than waiting for it.
A short draft order. Making the decision easy to implement improves the chances of it actually being made.
An undertaking about the new date. A clear statement that the extended date will be met carries weight, particularly on a second request.
| Feature | Before expiry | After expiry |
|---|---|---|
| Usual test | Good cause | Excusable neglect or similar |
| Explanation of delay | Helpful | Required |
| Consent decisive | Frequently | Less often |
| Typical outcome | Granted | Contested |
| Cost | Low | Substantially higher |
Timing the request
Ask as soon as the need is clear. The earlier the request, the less it looks like a response to a problem.
Do not wait for the last day. A request filed on the deadline gives the forum no time to decide it before expiry.
An undecided request is not an extension. The period continues to run while an application is pending unless the forum says otherwise.
Comply meanwhile if possible. Doing what can be done while the request is pending protects the position.
Ask the other side first. Consent converts an application into a formality in most systems.
Allow for the forum's own timetable. Applications take time to reach a decision-maker, and that time is part of the calculation.
Watch for a rule requiring a hearing. Some extensions cannot be granted on paper, which adds weeks.
Reapply promptly if refused. A refusal accompanied by reasons frequently indicates what a better application would have contained.
Do not let a pending request drift. Applications occasionally sit unread, and a polite inquiry after a week is better than assuming.
The test changes at the moment the period expires, and nothing about the quality of an application compensates for crossing that line. A modest request made in good time succeeds where a compelling one made late is argued about.
What weakens a request
Vagueness about the reason. Pressure of work is the most common explanation and the least persuasive.
No proposed date. An open-ended request invites a refusal or an extension shorter than needed.
Lateness in the period. A request made on the last day suggests the difficulty was known and left.
A history of extensions. Each request is read against the previous ones, per a second request for time.
Disturbing a hearing date. Extensions that put a fixed date at risk face much greater resistance.
Silence about the other side. Not saying whether consent was sought is read as not having sought it.
Overstating the difficulty. An explanation that does not withstand scrutiny damages the rest of the application.
Asking after the deadline. Which changes the test entirely, per seeking relief once the period has expired.
How it is managed
Review deadlines weekly. Most late requests are made because nobody looked until the week of the deadline.
Ask for consent by email. A short message setting out the request and the proposed date usually resolves it.
Keep the correspondence. An unanswered request for consent is evidence when the application is made.
Make one request, not several. Where more than one deadline is affected, dealing with them together is cleaner.
Do not treat consent as an order. Where the date was set by the forum, an agreement between the parties may need approval, per consent extensions between the parties.
Diarize the new date on receipt. Along with the source of it, so that the chain of extensions stays visible.
Recalculate dependent dates. An extension of one step frequently moves others.
Deliver by the new date. The strongest possible support for any future request is having met the extended date last time.
Tell the client what changed. Extensions move the shape of a case, and the person paying for it should hear about that promptly.
An extension sought while a period is still running is generally decided on good cause, which is a low bar that most genuine requests clear.
The application that works is specific: the deadline and its source, what has been done, why more time is needed, a realistic date, and the other side's position.
Timing matters more than content. A request made as soon as the need appears reads differently from one filed on the last day, and an application pending when the period expires does not stop it running.
Requests are weakened by vagueness, by the absence of a proposed date, by a history of previous extensions and by anything that puts a fixed hearing date at risk.
The habits that prevent late applications are unglamorous: reviewing deadlines weekly, asking the other side for consent by email, and diarizing every new date together with its source.
Points to carry away
- Before expiry the test is usually good cause.
- After expiry an explanation for the failure is also required.
- A realistic proposed date matters more than the reason.
- Consent from the other side makes it straightforward.
- Repeated requests are assessed against the earlier ones.
Questions readers ask
Is it worth asking the other side before applying?
Almost always. An extension the other party consents to is usually granted with minimal scrutiny, and in some systems the parties can agree certain extensions between themselves without any application at all. A short email setting out the request and the proposed date resolves most of them. Where consent is refused or ignored, the correspondence itself becomes useful material in the application, because it shows the request was made in good time and reasonably.
Does filing an application stop the deadline running?
Generally not. The period continues while the application is pending unless the forum orders otherwise, which means a request filed on the last day can leave a party out of time before it is decided. That is a strong reason to apply as soon as the need becomes clear, and to do whatever can be done to comply in the meantime, so that a refusal does not leave the position worse than it needed to be.
What is the most common reason an extension request fails?
Vagueness. An application that refers to pressure of work, does not say what has been done so far, and does not propose a specific date gives the forum nothing to grant. The second most common reason is timing: a request made on the deadline itself suggests that the difficulty was foreseeable and was left, and it removes any opportunity for the application to be decided before the period expires.

More in Pausing and Extending
A Second Request for Time
A repeat request is assessed against the previous one: whether the earlier estimate was realistic, what was done with the time granted, and whether the reason now is genuinely new. Systems that grant first extensions almost automatically become considerably more demanding on the second, and the strongest material is evidence of the work completed since.
Consent Extensions Between the Parties
Many procedural deadlines can be extended by written agreement between the parties, within limits set by the rules. Others were fixed by the forum or by statute and cannot be varied privately, however cooperative everybody is. Distinguishing the two categories before relying on an agreement is the whole of the exercise, and the distinction is usually stated in the rule that created the deadline.
Seeking Relief Once the Period Has Expired
An application made after expiry usually requires the applicant to show that the failure was excusable, that they acted promptly on discovering it, and that the other side is not materially prejudiced. Some deadlines admit no relief at all, so the first question is whether an application is available before it is drafted.
