Many contracts, at some point or another, will need to be revised. Sometimes the focus of the business changes, the ideas change, or better ideas are presented that make it necessary to alter the current contract by adding something to it - in that case, you would need a Contract Addendum.


There isn’t any need to completely re-do the whole contract when you only need to make a few additions to the current document. The Contract Addendum is as legally enforceable as the original contract and allows the parties to make necessary additions without having to renegotiate and/or rewrite the main contract again.

Frequently Asked Questions

A contract addendum allows a party to add to an existing contract without completely redoing the original document.

If you need to make any kind of additions to a contract or other legal document, you can use a contract addendum that keeps the original document mostly intact without having to renegotiate terms or rewrite the contract.

The main focus of a contract addendum is to fit the updated/added terms into the existing document. The title of the original document will be stated in the addendum, as well as the date that the original was signed. Whatever changes being made to the existing document/contract are then outlined and explained.

All parties who signed the original contract will also need to sign the addendum.

If you are revising or deleting any terms to the original contract, your addendum will be referred to as an amendment.

Generally, a contract addendum does not need to be notarized – you only need to sign the document to make it legally enforceable. A witness may be helpful if the other party attempts to contest the document, but a notary is not necessary.


Please Note: The use of a notary ensures that no one challenges any signatures later and is a secure way to firmly establish the effectiveness of your document.
