This document can be used to record the variation of an existing agreement. Therefore, this amendment agreement – a change in the terms of a contract proposal should be used when the parties to an existing contract wish to amend one or more provisions of a contract or agreement that have already been signed and are in force. This agreement amends the terms of an existing agreement to allow the contracting parties to change what they originally agreed. In order to enable the parties to guarantee the security of contractual terms at all times, most well-developed agreements will not take into account a change in the original terms without explicit written agreement. This contract amendment agreement is intended to be used in such situations and defines the agreed changes that must be made to the contract in question. An optional clause is also included, allowing parties to provide reasons or other explanations for the changes. Another option is to allow situations in which a surety has guaranteed certain obligations arising from the agreement to be amended. The existing agreement should be reviewed to determine who should sign the variation agreement.
