There are many forms of contracts and legal requirements. For instance, some contracts are subject to the Statute of Frauds, which requires an agreement in writing, signed by the alleged breaching party. Other forms of contracts — specifically those that deal with the sale of goods — have certain terms and conditions governed by the Florida Uniform Commercial Code. Regardless of the type of agreement, those accused of breaching a contract can raise the following defenses:

• Statute of limitations – in Florida, aggrieved parties have five years to file a breach of contract action. If a suit is brought more than five years after the alleged breach occurred, then the claimant is forever barred from recovering.
• Mistake – whether mutual or one-sided, a mistake of fact can generally excuse a party for not performing. Specifically, Florida law provides that if a contracting party is mistaken about a contractual term at the time of signing, this may serve as a valid defense to his or her non-performance.

Impossibility of performance – this is usually raised when a party is unable to perform under a contract due to issues beyond his or her control. In other words, if a condition makes it impossible for a person to perform his or her contractual duties, this defense will generally be sustained.
