Contract Amendment

A written contract amendment is often necessary to change agreed-upon terms in a legally-binding agreement.


  • Requesting an amendment to an existing contract.
  • Legally modifying an existing agreement.


Once an offer is accepted in exchange for some agreed-upon value, a legally-binding contract has been made. While contract negotiations often take much more complex forms, once a contract has been created the parties are bound to its terms unless they mutually agree otherwise. Any deviation from the terms and conditions of a contract may place one or more parties in breach of the agreement, which can give rise to legal liability. Many contracts – including real estate contracts and agreements for the sale of valuable goods – can only be changed by a written contract amendment that is signed by all parties to the original agreement.

Written contract amendments are often required when small deviations from the terms of an agreement may impact several other people. However, perfect performance of every obligation under a contract is sometimes not possible. A shipment of materials may be delayed, a particular product may no longer be available, or weather can shut down work on a project for a few days. Rather than risk liability for breach of contract, use a written contract amendment to make sure everyone is on the same page.

To make sure that all changes to a contract are clear and well documented, always use a written contract amendment to document any agreed-upon deviations from an original agreement. A contract amendment legally changes an existing contract, so all parties to the agreement should be clear on exactly how changes are to be made.
