Written by attorneys · grounded in primary & secondary sources — see below
An agreement between parties to a contract that grants additional time for performance of obligations under the original agreement. The extension suspends any default or termination that would otherwise occur at the end of the original period. Equitable considerations may support granting the extension even when one party holds over or fails to meet a deadline.

Holdover Tenant Receives Extra Time
After its lease ended, Harbor Haven continued operating its warming center for ten days due to an unexpected cold snap while seeking new space. The incoming tenant had a May 1 start date. Lewis and Harbor Haven then signed a written extension agreement allowing the nonprofit until April 15 to vacate. Because the parties validly agreed to the extension, the landlord could not unilaterally bind the tenant to a new full term during that period.
Mall Owner Extends Protest Period
Protesters distributed handbills in a privately owned shopping center. The owner initially demanded they leave immediately. The parties later executed an extension agreement giving the protesters until the end of the week to complete their activity and depart. The agreement postponed any self-help eviction or trespass claim during the extended window.

Common questions
Frequently Asked
4
Does an extension agreement need to be in writing to be enforceable?+
When the underlying contract falls within the Statute of Frauds, an extension that lengthens the total duration beyond one year must also be written. An oral extension of a multi-year lease is unenforceable even if the parties later act consistently with it.
Supporting sources
How does an extension agreement affect a landlord's right to elect a new term against a holdover tenant?+
If the parties validly agree to an extension of time to vacate, the landlord cannot unilaterally bind the tenant to another full term during the extension period. Equitable considerations may justify the extension when the tenant actually vacates before it ends.
Supporting sources
Can a creditor ignore an extension agreement and proceed with foreclosure?+
No. A signed extension agreement modifies the payment schedule and postpones default until the new deadline passes. The creditor must satisfy all conditions precedent, including any required mediation, before commencing foreclosure.
Supporting sources
What happens if one party to an extension agreement later claims economic duress?+
The agreement remains enforceable unless the threatened breach left the other party with no reasonable alternative and the ordinary remedy of damages would be inadequate. Mere economic pressure without that showing does not void the extension.
