A Letter of Variation is a formal document used to modify or amend the terms of an existing contract or agreement. It outlines the specific changes being made, the reasons for these changes, and the effective date of the variations. The letter is typically signed by both parties to the agreement, indicating their mutual consent to the changes.

What Is a Letter of Variation?
A Letter of Variation allows parties to change the terms of an existing contract. It formally records any agreed modifications. This document details what is changing, why the change is needed, and when it takes effect.
Common Uses Across Different Agreements
Businesses and individuals use letters of variation in many contract types. In employment contracts, they can adjust roles or pay rates. In business deals, they might change the payment schedule or delivery timeline.
Government projects often require contract amendments for funding or scope adjustments. In finance, banks and borrowers use these letters to revise loan terms or interest rates. This flexibility helps all parties adapt to evolving needs without ending the original deal.
Why a Letter of Variation Matters
A contract amendment keeps the relationship intact while updating the terms. This saves time and money for both sides. Additionally, it offers legal protection by showing that both parties agreed to the change. It also helps avoid confusion by clearly outlining new obligations and timelines.
Unlike verbal agreements, a written letter removes ambiguity. Thus, it protects the interests of everyone involved in the agreement.
What to Include in the Document
Start with an introduction that explains why the variation is needed. Then, list the changes in clear, numbered points. Mention the exact date when the new terms begin.
Finally, both parties should sign and date the letter to validate it. This ensures the letter of variation is legally enforceable and professionally handled.
