What is the required nature of signatures on bilateral contract modifications?

In the context of bilateral contract modifications, signatures are typically required from both parties involved in the contract to validate the modification. This requirement ensures mutual agreement and acknowledgment of any changes made to the original contract terms.

When a bilateral contract is modified, it reflects a negotiated agreement where both the government and the contractor recognize and authorize the adjustments. Thus, having the signatures as necessary underscores the principle of mutual consent, which is a cornerstone of contract law. Therefore, obtaining both parties' signatures minimizes disputes regarding the validity of the modification and reinforces the binding nature of the revised agreement.

In scenarios where only one party's signature is involved, it could lead to questions regarding the legitimacy and enforceability of the modification. Consequently, the necessity for signatures ensures that both parties are held accountable to the terms of the modification and that there is a clear acknowledgment of the changes being made.
