Reference
Identify the original agreement by title, original effective date, and parties to avoid ambiguity or overlap.
Updating an end date in writing reduces ambiguity about performance obligations, renewal triggers, and liability windows. A precise addendum preserves the original contract’s terms while providing a focused record of the timing change for audits and dispute resolution.
The same authorized signers from the original agreement should execute the addendum to avoid questions about authority and validity.
Identify the original agreement by title, original effective date, and parties to avoid ambiguity or overlap.
State the exact MM/DD/YYYY end date or formula for automatic renewal, including any notice windows.
Specify that only the termination date is altered and that all other terms remain in full force unless otherwise noted.
Confirm any consideration for the date change (if required) or state that no new consideration is exchanged.
Include signer names, titles, and a statement confirming each signer has authority to bind their party.
Provide signature blocks with printed names, dates, and optional notary/witness lines if local law or contract requires them.
