Final answer:
When a change is necessary to escrow instructions, both parties involved must agree to an amendment of the escrow instructions.
Step-by-step explanation:
When a change is required to escrow instructions, both buyer and seller must agree to an amendment to the escrow instructions. Escrow refers to a neutral third party holding funds during a transaction, which are released upon completion of agreed conditions. An amendment to the escrow instructions is necessary when the terms set forth in the original agreement need to be altered, and this must be done with the consent of both parties involved in the transaction. This contrasts with changing the purchase agreement itself, arranging new financing terms, or mutually terminating the contract, which are not specifically about modifying escrow instructions but rather relate to the broader agreement between buyer and seller.
