Avoidance Transactions Under IBC: Sections 43-51 Explained for 2026

For IIBF candidates preparing the Insolvency and Bankruptcy Code paper, avoidance transactions under IBC is one of the most examiner-favourite topics because it sits at the intersection of company law, forensic accounting and bank recovery. These are the dealings a corporate debtor entered into before its insolvency commencement date that unfairly drained value away from genuine creditors. When a company slides toward insolvency, promoters sometimes try to move assets out of reach before the resolution process can touch them — paying off a favoured creditor early, selling property to a relative at a fraction of its worth, or borrowing at ruinous terms from an insider. Chapter III of Part II of the Code (Sections 43 to 51, along with Section 66) gives the resolution professional a toolkit to identify, investigate and reverse exactly such dealings. This article walks through preferential, undervalued, extortionate and fraudulent transactions, the look-back periods that decide which deals get clawed back, and five practice MCQs to lock in the exam-ready detail.

The underlying logic is simple: once a company is in CIRP or liquidation, whatever assets remain belong to the entire creditor pool, not to whoever the promoters preferred at the last minute. Avoidance transactions law exists to restore the estate to the position it would have been in had those unfair dealings never happened, so recoveries are shared according to the statutory waterfall rather than insider favouritism. Four categories fall under this umbrella — preferential transactions, undervalued transactions, extortionate credit transactions, and fraudulent or wrongful trading — each with its own trigger test, its own look-back window, and its own remedy that the Adjudicating Authority (NCLT) can order once the resolution professional or liquidator files an application.

🔍 Preferential Transactions — Sections 43 and 44

A transaction is preferential under Section 43 when the corporate debtor transfers property or makes a payment that puts one creditor or surety in a better position than it would otherwise have received in a liquidation, and that transfer happened within the look-back period before the insolvency commencement date (ICD). The classic example is a company quietly clearing one lender's overdue dues while every other unsecured creditor is left waiting.

Section 43(3) carves out a genuine exception for payments made in the ordinary course of business or financial affairs of the debtor or the recipient — routine trade payments to suppliers on standard terms are not preferential just because the company was under financial stress. The resolution professional has to separate normal commercial conduct from deliberate favouritism, which is exactly the judgment call examiners like to test.

💡 Exam Tip: A transaction is not preferential merely because it disadvantages other creditors — it must also fall within the statutory look-back period and outside the ordinary-course exception. Both conditions have to hold together.

Once the RP flags a preference under Section 43, they apply to NCLT under Section 44, which can order the property returned, a security interest released, or the recipient made to pay back a sum representing the improper benefit received.

💰 Undervalued Transactions — Sections 45 to 48

Section 45 targets deals where the corporate debtor received significantly less value than it gave — selling an asset well below market price, gifting property, or forgiving a debt without adequate consideration. The resolution professional's job, laid out further in our chapter on the roles and duties of IRP and RP, includes actively forming an opinion on whether such a shortfall exists.

Section 46 fixes the relevant look-back period — generally one year before the ICD for transactions with unrelated parties, extended to two years where the counterparty is a related party of the corporate debtor, since insider deals deserve closer scrutiny for longer. Section 48 lets NCLT direct restoration of the position, including reversing the transfer or recovering the value gap from whoever benefited.

A subtlety candidates often miss: undervalued transactions and preferential transactions are not mutually exclusive. A single payoff to a related-party lender can be both a preference and an undervaluation if it combines favourable timing with inadequate consideration, and the RP can plead both grounds in the same NCLT application.

🚨 Extortionate Credit Transactions and Fraudulent Trading

Section 50 deals with extortionate credit transactions — loans the corporate debtor took on terms requiring exorbitantly harsh payments compared to the risk involved, essentially predatory lending against a company already in distress. Unlike preferential and undervalued transactions, the look-back period here runs two years before the ICD regardless of whether the lender was a related party.

Section 66 goes further and covers fraudulent trading and wrongful trading, where the business was carried on with intent to defraud creditors or for any fraudulent purpose, or where directors kept trading despite knowing insolvency was inevitable. There is no fixed statutory look-back period here — NCLT can reach back as far as the facts justify, and can hold the responsible persons personally liable to contribute to the assets of the corporate debtor.

⚠️ Common Mistake: Students often assume every avoidance category shares the same one-year or two-year cutoff. Extortionate credit transactions always use a flat two-year window, and Section 66 fraudulent trading has no fixed look-back at all — memorising a single number for all four categories is a guaranteed exam trap.

⏳ Look-Back Periods at a Glance

Because each avoidance category carries a different clock, candidates gain the most exam marks by memorising the comparison rather than the individual sections in isolation. The table below is the fastest way to revise this before a test.

Notice the pattern: related-party transactions always get the longer window because insiders have both the motive and the access to structure a quiet transfer, while extortionate credit ignores the related-party distinction entirely because predatory lending is harmful regardless of who is on the other side.

🏦 Why Bankers and Resolution Professionals Must Track Avoidance Transactions

For a banker sitting on the committee of creditors, avoidance transactions determine how much of the estate actually comes back for distribution. Every rupee clawed back under Sections 44, 48 or 51 adds to the pool available for financial creditors, which directly affects recovery percentages under the eventual resolution plan or, if the company slides into the process covered in our chapter on liquidation and voluntary liquidation, the liquidation waterfall itself.

The resolution professional's investigation typically starts with the transaction audit trail built during the structure of the IBC framework, cross-checking bank statements, board minutes and related-party registers against the look-back windows above. This overlaps closely with how banks structure emergency funding — see our piece on interim finance under IBC for how fresh lending is protected once CIRP begins, and our guide to personal guarantors under IBC for how recovery extends beyond the corporate debtor itself.

📌 Remember: Avoidance transaction proceedings can continue even after the CIRP concludes and a resolution plan is approved, if the plan itself reserves the right to pursue such claims — recoveries here are not lost just because the resolution process has formally closed.

Regulated lenders such as NBFCs and financial service providers face their own layered scrutiny during distress, covered in our article on insolvency of financial service providers, since sectoral regulators add conditions on top of the standard IBC avoidance framework. Sound credit appraisal upstream — including reading a borrower's exposure to cyclical sectors like the agriculture sector in the Indian economy — reduces how often banks end up on the wrong side of a preference claim in the first place. The Insolvency and Bankruptcy Board of India publishes detailed regulations on transaction audits at ibbi.gov.in that resolution professionals must follow.

🏁 Conclusion: Master Avoidance Transactions Under IBC

Avoidance transactions under IBC reward candidates who memorise the comparison across categories rather than each section in isolation — preferential and undervalued transactions share the one-year/two-year related-party split, extortionate credit stays flat at two years, and fraudulent trading under Section 66 has no ceiling at all. Reinforce this with timed practice rather than re-reading definitions alone. Take a full mock test at iibf.store/tests and revisit the look-back table until the four categories stop blurring together.
