defeasance
UCC / CommercialLegal glossary term
Quick answer
Defeasance usually means voiding a contractual obligation by fulfilling its requirements. In contracts, it matters because it immediately releases you from debt or collateral claims. Before signing, check if performance is automatic or requires formal notice.
Definitions
What is defeasance?
Legal Definition
Defeasance refers to the act of voiding a contractual obligation or lien by fulfilling its conditions, thereby removing it from legal existence. This action creates an immediate release or extinguishment of a prior right, such as a security interest in collateral securing debt. The critical qualifier involves whether the defeasance is automatic upon performance or requires formal notice.
Plain-English Translation
Defeasance is like when you return a library book on time; the fine (the obligation) disappears because you met the due date requirement. It cancels the rule, making it go away completely.
Contract relevance
Why defeasance matters in contracts
Ignoring defeasance means the original obligation survives despite performance; this can lead to ongoing liability for the debtor, even after they paid their debt. The defaulting party bears this risk.
Document context

| Promissory Note | Payment Schedule Section | Identifies the date/trigger for debt discharge. |
| Lease Agreement | Option to Purchase Clause | Confirms lease liability disappears after purchase completion. |
| Loan Default Notice | Cure Period Definition | Shows if curing a breach automatically defeats the default claim. |
Contract language
Common contract wording
| Contract wording | Plain-English meaning | What to check |
|---|---|---|
| Upon full satisfaction of this Note, all obligations shall be defeased. | This means paying everything wipes out the debt instantly. | Ensure 'full satisfaction' is clearly defined. |
| The lien will be defeased automatically upon remittance of final installment. | The security interest vanishes once you send the last check. | Verify that no extra paperwork is needed for this automatic release. |
| Defeasance requires written notice from Creditor to Debtor. | You must formally tell them you've paid before they lift their claim. | Confirm who has the burden of providing that official notification. |

Pre-signature checklist
What to check before signing
1
Is the trigger for defeasance automatic or conditional?
2
Who is responsible for providing the notice to complete the process (Debtor or Creditor)?
3
Does 'satisfaction' require payment, performance, or both?
4
What happens if the defeasance deadline passes without action?
5
Is there a specific required form or document for formal defeasance?
6
If multiple obligations exist, does satisfying one defeat them all?
Party impact
How defeasance affects each party
| Party | What this party should check |
|---|---|
| Debtor/Obligor | Must ensure they meet the conditions (pay on time, perform correctly) to trigger release. |
| Creditor/Lender | Must confirm that performance has occurred and take steps to formally acknowledge or enact defeasance. |
Comparison
defeasance vs similar terms
| Related term | Plain meaning | Main difference from defeasance |
|---|---|---|
| Rescission | Unwinding a contract entirely; defeating it by mutual agreement to go back to where you started. | Defeasance usually discharges an obligation *while* keeping the original contract structure intact. |
| Waiver | Voluntarily giving up a right without formally voiding the whole obligation. | Waiver lets you skip a requirement temporarily; defeasance completely removes it from the books. |
| Novation | Replacing an old duty with a brand-new one (a third party often steps in). | Defeasance discharges the *old* duty, leaving the contract intact unless otherwise specified. |
Missing or vague
If defeasance is missing or vague
If defeasance is undefined, courts might struggle to determine if performance was truly sufficient.
Disputes often arise over whether a simple payment check constitutes 'full satisfaction' or if it requires an accompanying letter.
Furthermore, ambiguity regarding the notice requirement forces parties into costly litigation just to prove when the debt legally vanished.

Document context
How defeasance shows up in legal documents
Why does it matter?
Ignoring defeasance means the original obligation survives despite performance; this can lead to ongoing liability for the debtor, even after they paid their debt. The defaulting party bears this risk.
When does it matter?
Defeasance triggers when a specific condition is met, such as when the final installment payment clears or a defined regulatory milestone passes within 30 days of signing.
Where is it usually seen?
You frequently encounter defeasance in standard mortgage deeds, UCC Article 9 security agreements, and loan covenants detailed in commercial financing documents.
Who is affected?
The debtor gains the right to clear title upon successful performance; the creditor loses their enforceable claim when the obligation is defeated. Both parties are defined by this change.
How does it work?
First, a party must satisfy all prerequisites outlined in the contract, like timely payments or specific covenants. Then, the legal status of the obligation changes from active to voidable. Finally, the defeasance effect takes hold, releasing the original duty.
