Which is NOT a characteristic of a valid contract release?

A valid contract release typically requires mutual agreement and the presence of essential elements that define a contract, such as consideration, legal capacity, and lawful purpose. The correct choice indicates that a release does not necessarily need to be in writing to be valid, as oral agreements can also suffice in many jurisdictions. However, while a written release is often advisable for clarity and to provide proof of the agreement, it is not a mandatory characteristic for the release to be valid.

The necessity of mutual agreement is fundamental in contract law, as both parties must consent to the terms of the release for it to be enforceable. Furthermore, all essential elements of a contract must be present, ensuring that the release meets legal standards. While signatures from all involved parties can strengthen the validity of the release, especially in legal contexts where proof may be necessary, they are not strictly required for the release to be considered valid. In summary, the flexibility around the written form of a release sets it apart, highlighting that such contracts can be effectively executed without a written document under various circumstances.
