What is a Contract Addendum?

The Contract Addendum Template is essential for businesses operating under Singapore jurisdiction who need to modify existing contractual arrangements. This template provides a standardized framework for implementing changes to original agreements while ensuring compliance with Singapore's legal requirements. The document is particularly valuable when parties need to update terms, add new provisions, or clarify existing clauses without creating an entirely new contract. It includes sections for identifying the original agreement, specifying modifications, and maintaining the validity of unchanged terms.

What sections should be included in a Contract Addendum?

1. Title and Date: Clear identification of document as an addendum and effective date

2. Original Agreement Reference: Details of the original agreement being modified including date and parties

3. Parties: Full legal names and addresses of all parties to the original agreement

4. Modifications: Specific changes to the original agreement, clearly identifying affected clauses

5. Confirmation of Other Terms: Statement that all other terms remain unchanged

6. Execution: Signature blocks for all parties

What sections are optional to include in a Contract Addendum?

1. Recitals: Background information explaining why modifications are needed - use when complex changes require explanation

2. Definitions: New terms being introduced in the addendum - use when new concepts or terms are being added

3. Effective Date Provisions: Specific provisions about when changes take effect - use when implementation timing is complex or delayed

What schedules should be included in a Contract Addendum?

1. Modified Clauses Schedule: Complete text of modified clauses showing both original and new versions

2. New Terms Schedule: Any entirely new provisions being added to the agreement

3. Pricing Schedule: Updated pricing information if modifications affect commercial terms
