Claim bifurcation in a bankruptcy cramdown is the rule that splits a single secured debt into two pieces based on what the collateral is actually worth: a secured claim equal to the property’s current value, and an unsecured deficiency claim for whatever the loan balance exceeds that value. The secured piece gets paid in full with interest through the bankruptcy plan. The unsecured piece drops in with credit cards and medical bills, which often pay out at pennies on the dollar. That split is what makes a cramdown save money.
A simple example makes it concrete. You owe $30,000 on a car loan, but the car is worth $20,000. Bifurcation treats $20,000 as a secured claim tied to the vehicle and the remaining $10,000 as an unsecured deficiency. Your plan pays the $20,000 (plus interest) over three to five years. The $10,000 gets lumped with your general unsecured debt and likely pays out a small fraction of face value. When the case ends successfully, the rest is discharged.
The Statute Behind the Split
The authority to divide a claim comes from 11 U.S.C. § 506(a). An allowed secured claim counts as secured only up to the value of the property securing it, and any amount above that value is unsecured.1Office of the Law Revision Counsel. 11 USC 506 – Determination of Secured Status That one sentence is the engine of every cramdown in Chapter 13, Chapter 11, and Chapter 12.
How the Collateral Gets Valued
Because the split happens at the collateral’s value, that number controls almost everything. For personal property in individual cases, § 506(a) requires valuation as of the petition date. For real property and Chapter 11 cases, courts have more flexibility and may value closer to plan confirmation.
The Supreme Court settled the method in Associates Commercial Corp. v. Rash: courts use replacement value, not liquidation or foreclosure-sale value. Replacement value is roughly what it would cost to buy a comparable item in similar condition on the open market. The Court reasoned that because the debtor is keeping and using the property, a use-based figure fits better than a fire-sale discount.2Cornell Law Institute. Associates Commercial Corp v Rash
Proof usually looks like a licensed appraisal for real estate and specialized equipment. For vehicles, courts routinely accept industry pricing guides adjusted for mileage and condition. Comparable sales in the local market carry weight too. Procedurally, Federal Rule of Bankruptcy Procedure 3012 governs the request to fix a secured claim’s value, and in Chapter 12 and Chapter 13 the valuation can be raised through the plan itself.3Office of the Law Revision Counsel. Rule 3012 – Determining the Amount of Secured and Priority Claims
Interest on the Secured Piece
You cannot simply pay the secured amount over time with no interest. The creditor is entitled to the present value of its secured claim, which means a reasonable rate added to each payment. The Supreme Court addressed how to set that rate in Till v. SCS Credit Corp., approving a formula approach that starts with the national prime rate and adds a risk adjustment, typically between one and three percent, based on the debtor’s circumstances and the plan’s feasibility.4Legal Information Institute. Till v SCS Credit Corp
As of late 2025, the prime rate sits at 6.75%, so Till-rate cramdown interest typically lands between roughly 7.75% and 9.75%. A higher prime rate narrows the gap between the cramdown rate and the original contract rate, which affects how much the debtor actually saves.
How Bifurcation Plays Out in Chapter 13
Chapter 13 is where most individual debtors run into bifurcation. The debtor proposes a repayment plan running three to five years, with the length tied to household income relative to the state median. Below-median debtors qualify for three years; above-median debtors generally commit to five.5United States Courts. Chapter 13 – Bankruptcy Basics
Through that plan, the secured portion of the bifurcated claim must be paid in full with Till-rate interest. The creditor keeps its lien until the debtor completes the plan or receives a discharge, at which point the lien is released and the debtor owns the asset free and clear. The present-value requirement is in 11 U.S.C. § 1325(a)(5)(B)(ii).6Office of the Law Revision Counsel. 11 USC 1325 – Confirmation of Plan
Debts That Cannot Be Bifurcated
Not every secured loan can be crammed down. Two major exceptions in Chapter 13 take bifurcation off the table entirely.
The 910-Day Rule for Vehicles
A provision often called the “hanging paragraph” in 11 U.S.C. § 1325(a) blocks bifurcation for a car loan when all three of these are true: the creditor holds a purchase-money security interest, the debt was incurred within 910 days before filing, and the vehicle was acquired for the debtor’s personal use. When those line up, § 506(a) does not govern, and the whole balance must be treated as fully secured regardless of what the car is worth today. A similar restriction applies to other personal-use collateral purchased within one year of filing.7Office of the Law Revision Counsel. 11 USC 1325 – Confirmation of Plan
So if you bought a car two years ago for personal use and you are underwater on the loan, Chapter 13 will not let you cram it down. You either pay the full contract balance or surrender the car. The 910-day window (about two and a half years) wears off, so timing matters.
The Anti-Modification Rule for Home Mortgages
Under 11 U.S.C. § 1322(b)(2), a Chapter 13 plan cannot modify the rights of a creditor whose claim is secured only by a lien on the debtor’s principal residence. Even if the home is deeply underwater, the mortgage stays fully secured and the terms cannot be rewritten through bifurcation.8Office of the Law Revision Counsel. 11 USC 1322 – Contents of Plan The Supreme Court confirmed this in Nobelman v. American Savings Bank, holding that § 1322(b)(2) blocks the use of § 506(a) to shrink an undersecured home mortgage down to fair market value.9Legal Information Institute. Nobelman v American Savings Bank
The word “only” in the statute does real work. If the mortgage is secured by the home plus other property, the protection falls away and the claim becomes eligible for bifurcation. But the ordinary residential mortgage, secured solely by the home, is off limits.
The Boundary: Stripping a Wholly Unsecured Junior Lien
There is an important exception inside the home-mortgage protection. Nobelman shields a mortgage that still has some equity behind it. A junior lien with no equity behind it at all gets no such protection. If the first mortgage balance equals or exceeds the home’s value, a second mortgage or HELOC is wholly unsecured, and in Chapter 13 the debtor can strip that junior lien entirely and reclassify it as unsecured.
Say the home is worth $400,000 and the first mortgage is $420,000. A second mortgage of $80,000 has zero collateral value and can be stripped. If instead the home were worth $450,000, the second mortgage would be partially secured by $30,000 in equity, and Nobelman would protect it. The line between partially secured and wholly unsecured is the whole fight.
This option does not exist in Chapter 7. The Supreme Court held in Dewsnup v. Timm that § 506(d) does not permit lien stripping in Chapter 7, and extended that reasoning to wholly unsecured junior mortgages in Bank of America v. Caulkett.10Justia. Bank of America NA v Caulkett A Chapter 7 debtor whose junior mortgage is completely underwater cannot void that lien. That is one reason some debtors who qualify for Chapter 7 still choose Chapter 13.
Cramdown in Chapter 11
Chapter 11 reorganizations have their own framework under 11 U.S.C. § 1129(b). When a secured creditor class votes no, the court can still confirm the plan if it does not discriminate unfairly and is “fair and equitable” to that class.11Office of the Law Revision Counsel. 11 USC 1129 – Confirmation of Plan For secured creditors, that usually means lien retention with deferred payments equal to the present value of the collateral, a sale free and clear with the lien attaching to proceeds, or delivery of the indubitable equivalent of the claim.
The bifurcation mechanics are the same § 506(a) split. The difference is that Chapter 11 plans are not boxed into three to five years, so business debtors can structure longer repayment terms that match the useful life of the collateral or projected cash flow.
Subchapter V Small Business Cases
Subchapter V of Chapter 11, available to small businesses with aggregate debts of $3,024,725 or less, breaks from the home-mortgage rule in a specific way.12Department of Justice. Subchapter V Under 11 U.S.C. § 1190(3), a Subchapter V debtor can modify a mortgage on a principal residence if the loan proceeds were not primarily used to buy the home and were primarily used in the debtor’s small business.13Office of the Law Revision Counsel. 11 US Code 1190 – Contents of Plan A home equity loan taken out to fund the business is the classic case.
Chapter 12 Family Farmers and Fishermen
Chapter 12 allows family farmers and commercial fishermen to bifurcate secured claims under the same § 506(a) framework. One useful wrinkle: if the underlying loan was originally scheduled over more than five years, as farmland mortgages and major equipment loans typically are, the debtor can continue paying on the original schedule, provided arrearages are cured during the plan period.14United States Courts. Chapter 12 – Bankruptcy Basics That matters for agricultural debtors carrying long-term land debt, where compressing payments into three to five years would not pencil out.
Tax Treatment of the Discharged Deficiency
When the unsecured deficiency gets discharged at the end of the bankruptcy, that forgiven amount would ordinarily be taxable income. 26 U.S.C. § 108(a)(1)(A) carves out a blanket exclusion: debt canceled in a Title 11 case is not included in the debtor’s gross income, as long as the cancellation was granted by the court or occurred under a court-approved plan.15Office of the Law Revision Counsel. 26 USC 108 – Income From Discharge of Indebtedness
The trade-off is tax-attribute reduction. In exchange for keeping the discharged amount out of income, the debtor has to reduce items like net operating losses, capital losses, credit carryovers, and the basis of property, in a specific statutory order.16Internal Revenue Service. Publication 908 – Bankruptcy Tax Guide For an individual with few tax attributes, that reduction may barely register. For a business with meaningful carryforwards, it can shift future tax liability.
If the Case Is Dismissed, the Cramdown Unwinds
Bifurcation only sticks if the debtor completes the plan or receives a discharge. If the case is dismissed before that, 11 U.S.C. § 349(b) rolls the bankruptcy back as far as practicable and restores property rights to where they stood when the case was filed, including reinstating any lien voided during the case.17Office of the Law Revision Counsel. 11 USC 349 – Effect of Dismissal
In practice, dismissal means the split never happened. The creditor’s original lien snaps back to the full loan balance. The unsecured deficiency classification disappears. Any stripped junior lien is reinstated. The creditor can resume collection, including foreclosure or repossession, on the original loan terms. That is the risk running under every cramdown: the plan has to hold up for its full term, or the savings go away.
