Addendum: Definition, Example and Related Terms
What is an Addendum ?
An 'addendum' is a formal, written follow-up to an original contract or agreement. It's like an appendix in a book; it adds extra information or clarifications after the main document is already complete. In the commercial world, an addendum might be used to include additional details about the terms of a deal, specify the scope of work in more detail, or insert new clauses that were agreed upon after the original contract was signed. For instance, if two companies agree to extend the deadline for a project, they might draft an addendum to reflect the new timeline. Or, if they decide to add more deliverables to a service contract, an addendum would specify what those deliverables are and how they affect pricing and deadlines. It's a way to make official changes without rewriting the entire contract.
An Addendum is not to be confused with an amendment. Although they are frequently used interchangeably. An Addendum means additions to the contract. Amendments are changes to exisitng terms that were already agreed.
