A failed payment does not delete your application, and a double debit is almost always reversed. What you have to protect is the deadline: 31 October 2026, form submitted and paid by 11:59 pm. An unpaid form is not an application, however complete the rest of it looks.
This page is the order to do things in when the payment goes wrong, and it is deliberately specific about which parts are documented and which are not. Where a rule has not been published for this cycle, it says so rather than guessing.
First: what actually happened
Three different things get called "payment failed" and they need different responses.
The money left your account and the portal says unpaid. The gateway did not confirm the transaction to the Consortium. The debit is pending settlement and reverses when it is not claimed.
The money left your account and the portal says paid. Nothing is wrong. Download the confirmation and stop worrying about it.
The money left your account twice. One of the two will reverse on its own in most cases. Where it does not, it is a refund request, and refund requests need reference numbers you will only have if you collected them at the time.
So the first action is not to pay again. It is to open your application dashboard on the Consortium portal, refresh, and read what it says about the fee. A payment that fails at the gateway sometimes registers at the other end a few minutes later.
The waiting window, and when to stop waiting
The Consortium does not publish a reversal window. The rule that applies is the Reserve Bank of India's: under its turn-around-time framework for failed transactions of 20 September 2019, an online card payment or a UPI payment to a merchant that is debited but not confirmed has to be auto-reversed within T + 5 days. T is the day of the transaction and the days are calendar days. Beyond that the bank owes you Rs 100 for each day of delay. Many reversals arrive sooner; five days is the outer limit the bank is held to.
That window is why the date you attempt payment matters more than anything else in this piece. Pay in the first week of October and a failure costs you nothing: you wait, you see, you retry, and there is still a month in hand. Pay on 30 October and a failure costs you the cycle, because there is no time left for a reversal, a retry and a second failure.
If the fee is still unpaid on your dashboard after that window, pay again. And if the deadline is closer than five days, do not wait for the reversal at all: pay again and sort out the first debit with your bank afterwards. A stuck debit can be chased in November. The deadline cannot.
Collect these before you do anything else
Every conversation that follows — with the bank, with the gateway, with the Consortium — needs the same handful of facts, and they are far easier to collect now than to reconstruct in three weeks.
- Your CLAT application number.
- The transaction reference or order ID from the payment screen, for every attempt.
- The date and time of each attempt, to the minute.
- The bank statement line for each debit, with the narration exactly as your bank prints it.
- A screenshot of the payment screen and of the application dashboard showing the fee status.
Put them in one place. A refund request with two reference numbers attached is a clerical matter; the same request without them is an argument.
If you have been charged twice
Raise it on both sides at once, because the bank and the Consortium hold different halves of the record.
With the Consortium, the published route is the Help Desk: email clat@consortiumofnlus.ac.in, call 080-47162020 between 10 am and 5 pm on working days, or submit the query form on that page and choose "Payment related" as the type of query. Set out the registration number, both reference numbers, both timestamps and the amounts. With your bank, raise a duplicate-transaction dispute with the same details.
Keep it in writing throughout. A phone call that resolves nothing leaves nothing behind; an email leaves a record with a date on it.
Be clear about what is and is not promised. The Consortium's instructions say the application fee is "non-refundable or non-adjustable", and they set out no procedure or timeline for returning a second payment made by mistake. The refund policy published for the portal's payment service says that once a refund request is approved by the institution, the refund is initiated to the source account within five working days. So the decision sits with the Consortium, and the request has to be made. That is the whole of what is published, which is why the reference numbers matter.
The other things that go wrong at this stage
Payment is the failure that frightens people, but it is not the most common one.
Photograph and signature rejected. The form asks for both in JPEG or PNG: a recent, front-facing photograph on a light background, and a signature in black or blue ink on a white background. Neither needs attesting. Certificates are different: they go up as PDFs, each under 1.5 MB. The form does not state pixel dimensions for the photograph and gives you a crop tool instead, so ignore the pixel figures that circulate elsewhere, re-save the image in the right format and crop it on the portal. Retrying the same file will fail the same way.
Category certificate in the wrong form. This one is worth taking seriously, because it surfaces at verification rather than at upload — long after you have stopped thinking about it. An OBC-NCL certificate in particular is tied to a financial year, and it is the university admitting you that decides whether yours is recent enough. The category itself cannot be changed once the form is submitted and paid. The category certificate guide covers what each category needs.
Details that do not match your Class 10 certificate. Name spelling, date of birth and parents' names are checked against documents later in the process. A mismatch introduced now is a problem at counselling, when it is much harder to fix.
An email address you do not actually read. Every notification in this cycle goes to the address on the form. Use one you open.
What not to do
Do not start a second application. The instructions are explicit: where a candidate has filled in more than one form, only the last one is considered, and the fee for the earlier one is not refunded. A second form to get round a payment problem costs you a second fee.
Do not pay through a third party offering to "complete" your registration. There is no such service. Handing over your login to one is how applications get altered.
Do not treat a screenshot of a debit as proof of payment. The Consortium's record of the fee is what counts, and that is what your dashboard shows.
Do not leave it to the last week. Portals slow down as the deadline approaches, and a gateway timeout on 31 October has a different consequence from the same timeout on 3 October.
Once the payment is through
Download the completed application and the payment confirmation, and keep both. Then go back to preparing: the CLAT 2027 hub lays out what comes next, from the admit card through to counselling, with the confirmed dates separated from the ones still being estimated.
If you have not measured where you stand recently, the free Diagnostic Test is a full-length paper on the current pattern with a section-wise and timing breakdown at the end. Registration being sorted is a good moment to find out what the next two months actually need to fix.
