An amendment does not replace the entire original contract, but only the modified part with the amendment. Once the change is complete, the agreement must be signed and notarized by both parties. Submit the amendment with the original contract and maintain it so that anyone reviewing the contract knows that it has been amended and is therefore no longer representative of the entire agreement. This amendment agreement can be used to supplement or modify an existing contract. It should be used to document revisions, additions, and deletions of the terms of an active and fully executed agreement. If you only need to make multiple changes to a contract, it`s much easier to make a change than to create a brand new contract from scratch. Your change request should include information such as: Make sure you are as specific as possible and include the numbers and names of the subsections if they are present in the original contract. It is also possible to include a choice of law provision. This provision prescribes which state law is used to interpret and regulate the terms of the contract in the event of a future dispute.
