The Bankruptcy Code invalidates "ipso facto" clauses in executory contracts or unexpired leases that purport to modify or terminate the contract or lease (or the debtor's rights or obligations under the contract or lease) based solely on the debtor's financial condition or the commencement of a bankruptcy case for the debtor. It also invalidates state law, rather than a contract, that purports to alter the property interests of the debtor. A more difficult situation arises when those interests are on the outer bounds of "property of the estate."

Bankruptcy trustees and chapter 11 debtors-in-possession ("DIPs") frequently seek to avoid fraudulent transfers and obligations under section 544(b) of the Bankruptcy Code and state fraudulent transfer or other applicable nonbankruptcy laws because the statutory "look-back" period for avoidance under many nonbankruptcy laws exceeds the two-year period governing avoidance actions under section 548.

Exculpation clauses limiting the liability of certain entities for actions taken in connection with a bankruptcy case are a common feature of chapter 11 plans. However, courts disagree over the permitted scope of such clauses. They also disagree as to whether an order confirming a chapter 11 plan that includes exculpation and third-party release provisions is insulated from appellate review under the doctrine of "equitable mootness."

A handful of recent high-profile court rulings have considered whether a chapter 11 debtor is obligated to pay postpetition, pre-effective date interest ("pendency interest") to unsecured creditors to render their claims "unimpaired" under a chapter 11 plan in accordance with the pre-Bankruptcy Code common law "solvent-debtor" exception requiring a solvent debtor to pay pendency interest to unsecured creditors. The U.S. Court of Appeals for the Second Circuit weighed in on this question in In re LATAM Airlines Grp. S.A., 55 F.4th 377 (2d Cir. 2022).

Whether a contract is "executory" such that it can be assumed, rejected, or assigned in bankruptcy is a question infrequently addressed by the circuit courts of appeals. The U.S. Court of Appeals for the Fifth Circuit provided some rare appellate court-level guidance on the question in Matter of Falcon V, L.L.C., 44 F.4th 348 (5th Cir. 2022). The Fifth Circuit affirmed lower-court rulings determining that a surety contract was not executory because the surety had already posted irrevocable surety bonds and did not owe further performance to the debtors.

A long-standing legal principle is that liens pass through bankruptcy unaffected. Like every general rule, however, this tenet has exceptions.

A hornbook principle of U.S. bankruptcy jurisprudence is that valid liens pass through bankruptcy unaffected. This long-standing principle, however, is at odds with section 1141(c) of the Bankruptcy Code, which provides that, under certain circumstances, "the property dealt with by [a chapter 11] plan is free and clear of all claims and interests of creditors," except as otherwise provided in the plan or the order confirming the plan.
