In short. Most of the commercial court mistakes that really hurt a business happen before anyone files. Thin paperwork. Waiting too long. Skipping Section 12A mediation. Picking the wrong court. Others come later: holding back documents, missing the 120-day deadline for the written statement, treating adjournments as free. A few hours of preparation prevents most of them. This guide is for owners, finance heads and in-house teams in Delhi NCR who are about to sue, have just been sued, or want their next dispute to be winnable.
Is this your situation?
- Your suit is drafted and ready, and you'd hate for it to bounce back from the registry or get thrown out at the first hearing.
- A courier with court summons landed on your desk yesterday. Nobody can tell you how many days you've got.
- Your last recovery suit was dismissed, or the plaint came back, and nobody ever properly explained why.
- Almost all your proof is emails, WhatsApp messages and NEFT entries.
- Sales keeps one set of records, accounts keeps another, and the dispute file belongs to nobody.
- You won a decree a few years ago. Not a rupee has come in since.
Where businesses lose the most
The mistakes that cost businesses most in commercial court aren't usually clever legal ones. They're everyday business habits, and they've run straight into a strict procedure. The Commercial Courts Act, 2015 and the amended Code of Civil Procedure, 1908 (CPC) set fixed deadlines, want every document up front, and punish delay with costs. If you grew up on the old civil court rhythm of adjournments and late filings, those same habits will now lose you cases.
We've listed the ten we see most in Delhi NCR files, roughly in the order they happen, from the day a contract is signed to the day a decree is executed. Some can be fixed if caught early. A few can't be fixed at all. Missing the 120-day written statement deadline is one. Letting a claim go time-barred is another.
We've kept this at the level of business decisions. For narrower questions, there are separate guides on commercial suits dismissed on technical grounds, on the reasons recovery cases fail, and on errors people make drafting a summary suit plaint.
Mistake 1: A thin paper trail, years before any dispute
Most commercial suits turn on papers created long before anyone thought of court. A purchase order the buyer signed. A delivery challan with a stamp and a signature. An email agreeing to a new rate. A balance confirmation at the end of the quarter. That's what the judge reads first. It's not glamorous. If you supply against phone calls, change prices through WhatsApp voice notes and never ask for a balance confirmation, you start the case on the back foot.
Fixing it is cheap and boring. Get signed purchase orders, or at least an email accepting your quotation. Get delivery proof for every consignment. Send a ledger to your big customers every quarter or year and ask them to confirm it in writing. Keep master copies of contracts in one place, not in some sales manager's personal Gmail. And remember that a written acknowledgment of the debt restarts limitation under Section 18 of the Limitation Act, 1963. That matters enormously later.
Our guide on the contract clauses that decide court cases later covers the interest, jurisdiction and dispute resolution clauses you'll want in place before trouble starts.
Mistake 2: Waiting until the debt is stale and the debtor has moved on
People wait for all sorts of reasons. They want to keep the customer. The debtor keeps promising. Nobody's been given the decision. The law doesn't wait for any of it. Most money claims have to be filed within three years under the Limitation Act. Article 14 covers the price of goods sold and delivered, Article 18 the price of work done, Article 55 breach of contract, and Article 113 is the residuary period. A written acknowledgment signed before time runs out, or a part payment, gives you a fresh period under Sections 18 and 19. A promise on the phone doesn't.
Delay costs you in another way the Limitation Act doesn't measure. A struggling debtor sells off stock, shifts receivables to a group company, or lets its bank accounts run dry. File two and a half years later and the money may just not be there. The counting rules are in our guide on the time limit to recover unpaid dues.
We suggest a simple internal rule. Any business debt 90 days overdue with no written commitment gets escalated. That doesn't mean you sue at 90 days. It means someone looks at the file, sends a proper notice and makes a decision.
Mistake 3: Skipping Section 12A mediation, or going through the motions
Under Section 12A of the Commercial Courts Act, pre-institution mediation is compulsory for a commercial suit unless the suit contemplates urgent interim relief. In Patil Automation v. Rakheja Engineers (2022), the Supreme Court held that a suit filed without it, from 20 August 2022 onwards, is liable to be rejected under Order VII Rule 11 of the CPC. In Delhi, it's the commonest reason a commercial suit gets thrown out at the threshold.
Some plaintiffs try to dodge mediation by tacking on a token prayer for an injunction. Judges see through it. In Yamini Manohar v. T.K.D. Keerthi (2023), the Supreme Court said the court has to look at the plaint and documents and decide whether the urgency is real. A plain money claim dressed up as urgent can still be rejected. If you really do need an injunction, plead the urgency with facts and evidence. Our guide on getting an injunction without mediation explains what courts accept.
The opposite mistake? Sending an unprepared junior to the mediation. It's a negotiation with a neutral person in the room. A claimant who turns up with a clean statement of account, a realistic settlement range and authority to sign can get paid within weeks. Treat it as your first real chance at the money.
Mistake 4: The wrong court, or forgetting what your own contract says
Three questions decide where the case goes. First, is it a commercial dispute under Section 2(1)(c) of the Act, with a specified value of Rs 3 lakh or more? Second, how much is it worth? In Delhi, suits up to Rs 2 crore go to the District Judge (Commercial Court), and anything above Rs 2 crore goes to the Commercial Division of the Delhi High Court. Third, under Section 20 of the CPC, where did the cause of action arise, or where does the defendant carry on business? Noida, Ghaziabad, Gurugram and Faridabad work differently. There, the court designated as Commercial Court for the district hears commercial suits whatever their value.
Businesses slip by choosing the court nearest their own office, by forgetting that interest can push a claim over Rs 2 crore, or by overlooking a clause in their own contract. Say the contract gives exclusive jurisdiction to Gurugram courts, and Gurugram courts do have jurisdiction. A suit filed in Delhi won't usually survive. An arbitration clause lets the defendant ask for the dispute to be sent to arbitration under Section 8 of the Arbitration and Conciliation Act, 1996. Either way you get a returned plaint or a referral. And months go.
Before anyone drafts, read the dispute clause in every document both sides signed. That includes the small print on the back of the invoice. The value and territory rules for Delhi NCR are on our page about which court will hear my case.
Mistake 5: A claim that's inflated, split or muddled
Your claim has to be one number, and the ledger, the legal notice, the mediation application and the plaint all have to back it. Suppose the notice says Rs 38 lakh, the plaint says Rs 41 lakh, and the statement of account attached adds up to Rs 39.6 lakh. The defendant's first argument writes itself. Reconcile before you file. Explain every difference, such as interest added up to the filing date.
Inflation is a separate problem. Bolt Rs 50 lakh of damages for loss of reputation onto a Rs 60 lakh invoice claim and you've raised the court fee, invited a defence and made the whole claim look shakier. Splitting's worse. File for the admitted invoices now, planning to sue on the disputed ones later, and the second suit may be barred by Order II Rule 2 of the CPC. That rule wants the whole claim from one cause of action brought in one go.
Muddling is when one suit throws together unrelated contracts, parties and periods without showing how they connect. Keep it simple. Who owes what. Under which document. Since when, and why.
Mistake 6: Holding documents back, and signing the statement of truth without reading it
For commercial suits, Order XI of the CPC as amended requires each side to file, with its pleading, every document relating to the suit that's in its power, possession, control or custody. That includes the ones that hurt. A document you didn't disclose then usually can't be relied on later unless the court gives leave and you show reasonable cause. Businesses still sit on a damaging email, or don't bother looking beyond the obvious invoices. Both are dangerous. The other side very often has the same email.
The plaint and the written statement also need a statement of truth under Order VI Rule 15A, signed by someone who knows the facts. It's a sworn confirmation. It isn't a signature page. When a director signs it without reading the plaint, and the plaint gives a delivery date or an admission that the company's own records contradict, that statement gets used against the company in cross-examination, and the court may award costs. Our guide on how a wrong statement of truth hurts you sets out what can happen.
Before Advocate B.K. Singh finalises a plaint, he sits with whoever will sign the statement of truth and goes through it line by line. For each fact, he asks them to point to the document. If they can't, either the document turns up that day or the line comes out. It's a slow meeting. It saves far more time in cross-examination.
Mistake 7: Filing emails and WhatsApp chats without proving them
Electronic records make good evidence, often better than paper, because they're dated and hard to fake. But you have to prove them. Since 1 July 2024, Section 63 of the Bharatiya Sakshya Adhiniyam, 2023 requires a certificate with any electronic record produced as evidence. It replaced Section 65B of the old Evidence Act. Businesses file screenshots without the certificate. They print WhatsApp chats without showing whose phone they came from. Or the phone walks out the door with an employee who quits.
Protect the source. While you still control the device and the account, export chats and emails with dates and headers. Decide who'll sign the certificate and who'll give evidence about it. Our guide on proving emails and WhatsApp chats in a commercial court takes you through the certificate.
Linked to this is picking the wrong witness. The managing director who signed the contract may know nothing about the 140 invoices the accounts team raised. Choose someone who actually handled the account and can speak to the ledger. Then prepare them for cross-examination on it.
Mistake 8: Ignoring the summons, or letting 120 days slip by
This one's made by defendants. It's the hardest to undo. In a commercial suit the written statement is due within 30 days of service of summons. The court can extend that, usually on costs, but never beyond 120 days from service. Past 120 days, the right to file the written statement is forfeited, and that's not a technicality you can argue your way around, because the Supreme Court settled it in SCG Contracts v. K.S. Chamankar (2019). You can still cross-examine and argue. What you can't do is put forward your own version of the facts. That's gone.
We've seen businesses lose this deadline in ways that are depressingly predictable, and almost never because anyone was careless in a dramatic way. Summons goes to an old registered office. The receptionist signs for a courier and it sits unopened. It's forwarded to a lawyer who only does criminal work. The finance head decides it's a pressure tactic and waits for the next date. Every one of these has finished off a defence.
Put one person in charge of every legal paper that comes in. The same day, diarise 30 and 120 days from the date of service. Get the papers to commercial counsel within the week. How the days are counted is explained on our page about the 120-day written statement deadline.
Mistake 9: Chasing adjournments and ignoring the timetable
Once pleadings close, the court holds a case management hearing under Order XV-A of the CPC and sets a timetable for documents, evidence and arguments. It's not decorative. The court expects you to keep to it. Courts can impose costs if you don't, and can close a party's evidence if it isn't led on the fixed dates. Asking for a date because the witness is travelling, or counsel is busy, was routine in the old civil courts. In a commercial court it's expensive.
Under Section 35 of the CPC, as substituted for commercial disputes, costs follow the event, and the court weighs conduct when it fixes them. Delay counts. So do frivolous applications, unreasonable refusal to admit documents and turning down a reasonable offer to settle. You can win on merits and still see your expected costs cut because you were the one causing repeated delay.
Our advice here is plain. The day the timetable is fixed, block your witnesses' calendars. Treat evidence dates like board meetings.
Mistake 10: Thinking about collection only once you have the decree
Until it's executed, a decree's just a piece of paper. Whether the defendant can pay is a question for the start of the case, not the end. Before filing, check the debtor's business status, the bank accounts you know from past payments, property and receivables. If there's real evidence the defendant is getting rid of assets to defeat a decree, the court can order attachment before judgment under Order XXXVIII Rule 5 of the CPC, or direct it to furnish security. Courts grant this only on specific facts. General worry isn't enough. See attachment before judgment.
Settlements go wrong the same way. A business agrees to take payment in instalments, records a vague compromise and withdraws the suit. The second instalment never arrives. Get the settlement recorded by the court, with a default clause, so that if they default you can execute for the full amount instead of starting over.
In the execution files that come to Advocate B.K. Singh, the commonest gap is that nobody kept track of the debtor's assets during the two or three years the suit ran. So he asks clients to keep a simple running note while the case is pending, listing every bank account, vehicle, property and big customer of the debtor that comes to their notice. That note usually becomes the backbone of the execution petition.
The price of each mistake
| Mistake | What usually follows | Time you typically lose | Can it be fixed? |
|---|---|---|---|
| Thin paper trail | Defendant says there was no contract, or disputes the rate. Summary judgment gets harder | A full trial where a quick decree was possible | Partly, if you collect acknowledgments before positions harden |
| Suing late | Claims time-barred, assets gone | Permanent, for barred claims | Only if a written acknowledgment or part payment restarted the clock |
| No Section 12A mediation | Plaint rejected under Order VII Rule 11 | Commonly 3 to 9 months, plus mediation time when you refile | Yes. Mediate and refile, if limitation hasn't run out |
| Wrong court or overlooked clause | Plaint returned, or the dispute sent to arbitration | Several months | Yes, by refiling before the proper forum |
| Inflated or split claim | Higher court fee. Order II Rule 2 bars the part left out | The omitted part is lost for good | An inflated figure can be amended. A barred part can't be revived |
| Hidden documents, careless statement of truth | Documents shut out, credibility dented, costs | Months of applications and hearings | Only with leave and a reasonable cause |
| Unproved electronic records | Objections, or the evidence ignored | Re-examination and fresh certificates | Usually, if the source still exists |
| Missed 120-day deadline | Right to file the written statement forfeited | Permanent | No |
| Adjournments, timetable ignored | Costs, and evidence closed | Months, and lower costs even if you win | Sometimes, on good cause and payment of costs |
| No thought for collection | A decree on paper, still unpaid | Years in execution | Partly, by tracing assets in execution |
Invented example: a Noida packaging unit that made four mistakes in one claim
This case is invented. A corrugated box maker in Noida Sector 63 supplies an FMCG distributor in Kirti Nagar, West Delhi. The distributor stops paying with Rs 74 lakh outstanding. Prices were revised twice over the relationship, both times in WhatsApp messages between the two sales managers. The box maker's sales manager has since left. His phone went with him.
First mistake. The legal notice demands Rs 81 lakh, applying the older, higher rate to part of the period. Second, to save time, the plaint asks for an injunction restraining the distributor from "alienating its assets" and skips mediation, though nobody has any evidence of an asset sale. Third, the rate revision chats go in as screenshots from the accounts head's phone, which only ever received forwarded copies, and there's no Section 63 certificate. Fourth, the managing director signs the statement of truth without spotting that the figures don't match.
The distributor moves under Order VII Rule 11. The commercial court at Tis Hazari rejects the plaint for want of Section 12A mediation, finding the urgency wasn't real. Five months gone. The box maker then mediates through the West district legal services authority, gets Rs 20 lakh as an interim settlement, and refiles for the balance. This time the figure is reconciled, the chats are properly exported from source, and the IT vendor that manages its company phones gives a certificate. The second suit proceeds on the merits. None of this is a real case. It's here to show how small errors pile up in a single file.
A pre-filing routine that heads off most of these mistakes
For a typical recovery claim it takes a few days. Not weeks.
Give the dispute one owner
Pick one person, usually from finance or legal, to gather documents, watch the dates and speak for the business. Disputes run by committee lose papers and miss deadlines.
Reconcile the account and settle on one figure
Match invoices, payments, credit notes and TDS against the ledger. Add interest to a realistic filing date. Use that same figure in the notice, the mediation application and the plaint, and explain any change.
Check limitation and read the clauses
Find the oldest unpaid invoice, and the latest written acknowledgment or part payment. Read every jurisdiction, arbitration and interest clause in the purchase orders, contracts and invoice terms.
Gather and preserve documents, bad ones included
Pull out contracts, orders, delivery proof, emails and chats. Export electronic records from source with dates, and line up the Section 63 certificate. Keep the documents that hurt you as well. You'll have to disclose them.
Go into Section 12A mediation with a plan
Apply to the legal services authority. Turn up with a statement of account and a settlement range, and send someone who can sign. Keep the final report safe, because the plaint needs it.
Read the plaint with whoever will sign it
Check every factual statement against the documents before the statement of truth is signed. Correct anything that isn't supported.

How the mistakes differ for suppliers, service firms, lenders, startups and big companies
Suppliers and manufacturers usually have invoices and delivery proof. What they lack is evidence of the agreed price and credit period, which is exactly where mistakes 1 and 5 hurt. MSME suppliers often forget that, as registered micro or small enterprises, they can claim interest at three times the RBI bank rate under Sections 15 to 17 of the MSMED Act, 2006, or go to the MSME Facilitation Council. Which route to take shouldn't be left to chance.
Service and IT firms live on milestone sign-offs, change requests and records in project tools. They trip most often on mistakes 6 and 7: partial disclosure of the project history, and electronic records nobody can prove. Lenders who made inter-corporate loans or advances tend to have clean documents but leave it too late. That's mistake 2, and the borrower's position gets worse every month they wait.
Startups under-document, over-trust big clients, and then hesitate to sue in case they lose the relationship. Large companies have the documents but lose deadlines somewhere in internal routing, which is mistake 8, and they spread disputes across group entities in ways that make disclosure messy. The routine above works for all of them. Only the step that needs most attention changes.
Already made one of these mistakes?
Plenty can be repaired if you don't sit on it. A shortfall in court fee can be made good within the time the court allows. A plaint returned for want of jurisdiction can be presented in the proper court, and under Order VII Rule 10A the plaintiff can ask the court to fix a date of appearance there, so the defendant needn't be served all over again. A plaint rejected for want of mediation can be refiled after mediation, as long as the claim is still within limitation. Pleadings can be amended under Order VI Rule 17 before trial starts, and in limited cases after.
Some can't. Miss the 120 days for the written statement and it's lost. A claim that became time-barred before any acknowledgment won't come back. A part of a claim you gave up or left out is usually gone for good. If that's where you are, the useful question is what's left: cross-examination, legal objections, a settlement on whatever is still arguable, or another remedy entirely.
If your case is already in court and something's gone wrong, fresh eyes on the order sheet and pleadings often turn up options you didn't know you'd still got.
Things to do this week
Take one disputed account and put it through the six steps above. Name an owner. Reconcile the figure, check the oldest invoice and the latest acknowledgment, read the dispute clauses, export the chats and emails, and decide whether to start mediation. If summons in a commercial suit has reached you, diarise 30 and 120 days from service today. The kinds of claims and defences we handle across Delhi NCR are listed on our commercial court services page.

Frequently asked questions
Why was my commercial suit rejected at the first hearing?
Usually for one of three reasons. It was filed without Section 12A pre-institution mediation when no urgent relief was really needed, the plaint itself shows the claim is time-barred, or the court lacked jurisdiction. Rejection under Order VII Rule 11 isn't always the end. Depending on why, you may be able to mediate and refile, or present the plaint in the right court.
Can I sue separately for invoices I left out of my first suit?
Usually not, if they came from the same cause of action. Order II Rule 2 of the CPC wants the whole claim in one suit, and an omitted part is barred unless the court gave leave. Take advice before you file for only part of what's owed.
Will a WhatsApp chat prove a price revision?
It can be strong evidence, particularly if the other side replied and acted on it. You'll need a certificate under Section 63 of the Bharatiya Sakshya Adhiniyam, 2023, and someone who can speak to where it came from. Screenshots of a forwarded copy are far weaker.
We got summons 100 days ago. Can we still defend?
Yes, just. The written statement has to be filed within 120 days of service, with costs for the delay past 30 days. Get the papers to a commercial lawyer today and file a complete written statement, with a statement of truth, before day 120.
Is a legal notice enough instead of Section 12A mediation?
No. A legal notice is your own demand. Pre-institution mediation is a statutory process before a legal services authority. Courts have rejected suits where the plaintiff relied on a notice alone. Send the notice, then apply for mediation, unless the suit genuinely needs urgent interim relief.
Can I add documents after filing a commercial suit?
Only with the court's leave, and only if you show reasonable cause for not disclosing them earlier, under Order XI of the CPC as amended for commercial suits. Courts are strict about it. Put everything relevant in with the plaint.
What if I keep asking for adjournments?
In a commercial court, adjournments usually come with costs, and if you keep failing to follow the case management timetable the court can close your evidence. The delay also counts against you when final costs are decided under Section 35 of the CPC.
How do I make sure I actually get paid after winning?
Think about the debtor's assets before you file, and keep tracking them while the case runs. If the debtor is disposing of assets to defeat a decree, apply for attachment before judgment with specific evidence. Once you have the decree, file for execution quickly and name the bank accounts, property and receivables.
