What is required for a contractor to change the terms of a signed contract?

For a contractor to change the terms of a signed contract, both parties involved must agree to the changes, and these changes should be documented in writing. This is critical for several reasons, including ensuring clarity, maintaining transparency, and protecting the interests of both the contractor and the client. When changes are not documented in writing, it can lead to misunderstandings or disputes regarding what was agreed upon, making it difficult to enforce the new terms later.

Written documentation serves as legal proof of the agreement and allows both parties to reference the modified terms if a conflict arises. This requirement aligns with best business practices and is often enforced by law to ensure that all parties have a clear understanding of their obligations and responsibilities following any modifications to the original contract.

In contrast, changing a contract at any time by the contractor alone, relying solely on oral agreements, or deeming changes impermissible would not provide the necessary protection or legal standing typically required in contractual relationships.
