What is a Purchase Contract Addendum?

A Purchase Contract Addendum serves as a formal modification to an existing purchase agreement when circumstances require changes to specific terms while maintaining the validity of the original contract. This document is commonly used when parties need to adjust pricing, delivery schedules, specifications, or other terms without creating an entirely new contract. Under U.S. law, the addendum must be in writing and signed by all parties to be legally binding, ensuring compliance with both federal and state contract laws.

3. Definitions: Key terms used in the addendum

4. Modifications: Specific changes to the original contract

6. Execution: Signature blocks and date of modification

What sections are optional to include in a Purchase Contract Addendum?

1. Additional Terms: Used when introducing new provisions not covered in original contract

2. Price Adjustments: Used when modifying payment terms or amounts
