• Which contract, which amendment

  The contract's date, title and any earlier amendments, this amendment's number and a one-line note of what earlier ones changed.

• Changes taking effect, and why

  An effective date, any retrospective application, and the reason for the changes.

• Terms changed, added and removed

  Four rows identifying each term and its new wording in full, plus separate blanks for additions and removals.

• Price, dates, supply and details

  Separate sections for payment changes, dates and duration, what is supplied and a replaced schedule, and changes to a party's name or notice details.

• Consents, confirmations and record

  Whether anyone else's agreement is needed, a guarantor confirming the guarantee extends, nothing given up unless stated, and keeping the amendment with the contract.

A contract amendment records changes two parties have agreed to a contract they have already signed. It identifies the contract and any earlier amendments, numbers this amendment, says when the changes take effect and why they are made, lists the terms changed, added and removed, and deals separately with price or payment, dates or duration, what is supplied and the parties' details.

This blank form is completed by hand and signed by both parties and, where one is needed, a guarantor or other consenting party. It confirms that the rest of the contract stays in force, that each signer is authorised, that nothing is given up unless it says so, and that the amendment is kept with the contract. Whether the contract itself requires a particular method or anyone else's agreement to change it depends on its terms, so read it first.
