Which of the following is NOT a requirement for a contract to be legally binding?

For a contract to be legally binding, it must meet several fundamental requirements, including having a legal purpose, mutual agreement among the parties involved, and consideration, which refers to the exchange of value between the parties. A notary public does not play a necessary role in the formation of all contracts. While notarization may be required for specific types of documents to enhance their legal standing, such as real estate transactions or other estate-related documents, it is not a universal requirement for all contracts. Therefore, the involvement of a notary public is not a prerequisite for a contract to be considered legally binding. This distinction helps emphasize that the essential elements of contract formation primarily focus on the agreements and intentions of the parties involved rather than on the formalities of notarization.
