Final answer:
The contract between Tallie and Bordie is unenforceable because the statute of limitations for enforcement has passed, meaning that while the contract still exists, judicial enforcement is no longer possible.
Step-by-step explanation:
The main answer to the question of what kind of contract exists today between Tallie and Bordie, given that Tallie has not fulfilled their obligations under the contract and the statute of limitations in their state is four years, would be that the contract is unenforceable. The fact that the time period set by the statute of limitations has expired means that parties cannot seek judicial enforcement of the contract through the court system. Although the contract was valid when it was formed, after the statute of limitations has passed, the right to file a lawsuit to enforce the contract is lost, therefore making the contract unenforceable.An unenforceable contract is valid, but for some legal reason, such as the expiration of the statute of limitations, cannot be enforced in a court of law. In this case, the contract itself may still exist, and the parties may voluntarily choose to fulfill the contract if they wish, but the legal ability to demand performance through the courts is no longer available.In conclusion, because Tallie has failed to fulfill their obligations within the timeframe required by law, and over four years have passed, the contract between Tallie and Bordie has become unenforceable.
