What factor is generally not considered when determining the validity of a contract in a breach of contract case?

The market value of the contract is generally not considered when determining the validity of a contract in a breach of contract case because the validity of a contract primarily hinges on the essential elements that constitute a contract, such as mutual assent (the intentions of both parties), consideration (something of value exchanged), and legality (the subject matter being lawful).

In breach of contract cases, the focus is on whether there was a valid contract formed and whether one party failed to uphold their obligations under that contract. Factors such as the intentions of the parties at the time the contract was created, the clarity of the terms of the agreement, and evidence of damages are critical in assessing whether a breach occurred and what the repercussions of that breach might entail.

Market value may play a role in assessing damages once a breach has been established, but it does not affect the foundational validity of the contract itself. Thus, the consideration of market value does not contribute to determining whether or not a contract is valid in the first place.
