An undersecured claim is a debt that is secured by collateral worth less than the total amount owed. In that situation, part of the creditor’s claim is treated as secured up to the value of the collateral, and the remainder may be treated as unsecured.

The term is easiest to understand by comparing the debt to the value of the Collateral that backs it.

Undersecured Claim Explained

The Ninth Circuit glossary defines an undersecured claim as a debt secured by property worth less than the amount of the debt. Section 506 of the Bankruptcy Code likewise explains that a secured claim is treated as secured only to the extent of the value of the creditor’s interest in the property, with the remaining shortfall treated as unsecured.

The Term Undersecured Claim in Different Legal Contexts

Undersecured claims matter most in bankruptcy and debtor-creditor law, where valuation of collateral affects plan treatment, cramdown issues, interest rights, and the division between secured and unsecured portions of a claim.

The status of a claim as undersecured can change if the collateral value changes or if the debt amount is reduced, so the concept often depends on case-specific valuation evidence.

Common Misconceptions About the Meaning of Undersecured Claim

A common misconception is that a secured claim is fully protected just because collateral exists. If the collateral is worth less than the debt, the claim is only secured to that lower amount.

Another misconception is that an undersecured claim is the same as an unsecured claim. It still has a secured component, but not enough collateral to cover the full debt.
