A contract may be modified, as long as both you and the vendor agree on the modification.

Such a modification must be made in writing and be clearly related to the contract, for example by including a reference to the contract number. The modification must describe the changes agreed upon, including:

  • any changes in price;
  • any changes in the amounts payable;
  • any changes in the terms of payment.

Once the contract is signed by the purchaser and the vendor, the modification is deemed part of the contract.
